There's a noise sensor which can adjust fan speed for maximum quietness with good thermals. Saw it on the KitGuruTech video. The noise sensor isn't there to spy on you though.

Sadly none of the mITX boards have more than 6 external USB ports. My old ASUS mITX has 8! And in really small mITX cases you can't add a bracket with more USB, because the two brackets are already used by the gfx card. Guess I have to wait for an enthusiast mITX board )-:
Are they really going up? I have 2 USB devices plugged in to my system - a keyboard and a mouse. I occasionally plug a USB stick in one of the front ports to transfer files. My phone and tablet sync over wifi, they don't get plugged in. I have a charger behind my desk and a cable to charge them. My printer is on the network. The one place I DO need lots of USB ports is also the place where I have a small cube case machine, with no discreete GPU, because it doesn;t need one. On that one I added a USB PCI card to get enough ports. In addition to the keyboard and mouse, that machine is on my workbench where it connects to several electronic test instruments and I have multiple cabled for programming microcontrollers. I also have a USB microscope for board inspection. And then I have 3 more USB devices connected for my other hobby that shares the bench. Plus a front port kept free for USB sticks. So the use case I have for more USB has the PCI slots open to add expansion cards, the use case where I have a discrete GPU eating up the slot space doesn't need an excess of USB ports.
But the new oculus stuff only uses 1 usb port, so that right there is a drop. I use 2 for keyboard and mouse, one for a wireless controller, and one for my HMD.
Must be nice to have no external hard-drives, I have 3 all needing their own USB 3 port, along with a Logitech dongle that runs both my mouse and keyboard, finally a Bluethooth dongle as my computer has none built-in. Yes I would need 6 USB ports (one open for USB sticks) just to keep even.
No, I have 3 usb ports on my laptop and i only use 1 for my mouse. As it turns out, the most amount of usb ports i use at once is two when i am making a wired data transfer with my mouse plugged in. Actually, I almost never transfer data to my phone with a wire, instead just sharing them via bluetooth. and considering i never make large data transfers to my phone, this works out just fine. as for a desktop, however, i'd like a minimum of 3 as i'll always have not only a mouse, but a keyboard plugged in all the time.
I think AMD screwed up here with pricing their platforms appropriately. I understand the push for PCIe 4 but they can't have average motherboard prices hovering between $200-$300. There has to be $100 motherboards to be taken seriously especially by OEM's if they want 4000 parts to become mainstream.
But maybe they don't...maybe they plan to milk the 3000 parts for a few years. After all, there isn't much reason not too. They have no competition from Intel in the budget segment right now.
Replace AMD in your sentence with motherboard makers AMD it not setting the price for them. Looking at list of boards here is seems most of them added features just to jack the prices up.
On one hand, you're right, on the other, AMD provides the chipset and specifications, and the fact that NO OEMs seem to be able to make cheap boards suggests that there's challenges with meeting the spec at a certain budget.
U have to understand amd didnt fuck up.motherboard companys didnt too because theres thing like covid and mb are made in china so Its more expensive to them now.And they have less stock and they still have to make money
I'm kinda disappointed they ended up missing the opportunity to go PCI-E 4 for the CPU to GPU link. With 2 10gbs USB ports, 2 5gbs USB ports, 10 flexible PCI-E lanes that can be NVME/ Sata ports or add on controllers on the chipset there's plenty of bandwidth there to be bottlenecked by a 4x PCI-E 3 link to the CPU. Going PCI-E 4 would make this somewhat less of a bottleneck and could support for example 2 NVME PCI-E 3.0 4X drives at full speed. The B350 more balanced in this way but sadly it was because the PCI-E off the chipset was only PCI-E 2. Hanging 16x lanes worth of things off a 4x link isn't great when they could have doubled that link bandwidth pretty easily.
That‘s X570. If you need the additional storage bandwidth, this is what you should go for.
Alternatively there is the Aorus board that offers the 8x CPU plus 2x 4x PCIe 4 lanes for nVMe drives plus the PCIe 3 lanes from the chipset. That could be an alternative and eight PCIe 4 lanes for the GPU should be fine with the next gen GPU, except perhaps for the top of the line models.
On the plus side, with Ryzen you have four dedicated PCIe lanes from the CPU for nVMe (16+4+4 vs. 16+4 on Intel).
The X570 goes whole hog on PCI-E 4 with PCI-4 hanging off the chipset too and it supports more PCI-E and SATA and USB devices hanging off the chipset so while the CPU to Chipset bandwidth is higher it's actually even more imbalanced between the combine possible bandwidth of devices possible off the chipset and the CPU to Chipset bandwidth.
Going PCI-E 4 for just the CPU to Chipset on the B550 would have given the option to decrease that imbalance and one PCI-E 4x link shouldn't have driven the power up too high.
Then most people wouldn't buy X570 and get B550 instead as there wouldn't be much of a difference. That, and having less PCIe 4.0 stuff lowers the power requirements a bit.
I personally held off on X570 because I knew I basically only needed the GPU and NVMe drive to be PCIe 4.0 for the most future-proof setup. I figure I'll buy new again when the new AM5 socket is released with Zen 4. Plus, some of the B550 boards have a Type-C front connector, which will go with the new ITX case I'm getting that has one on the front.
Yes, but then you need to add a separate PCIe controller on the chipset to handle just those 4 lanes. The market probably isn't big enough to make it worthwhile.
True, but would that not have brought back the requirement for an actively cooled chipset? That definitely contributes to cost, so it makes sense to cut that from the package.
Personally, I'm happy that we've finally left PCIe 2.0 behind. Such chipsets still being sold in 2020 is horrific.
I was hoping to build several B550 APU mITX systems this week, but the lack of a compatible APU has stopped those plans. AMD's decision regarding to use a prior generation micro-architecture for its APUs in addition to their decision regarding AM4 firmware size limits are really colliding to create a missed opportunity here. If the iGPU in the Comet Lake processors was better, I'd be picking up H460 or Q470 boards right now instead.
My understanding is that the firmware size limit wasn't created by AMD. The motherboard makers could always use firmware chips with a larger capacity. Intel doesn't have this problem since they only support one or two CPU generations per motherboard :-)
I've read elsewhere that Zen1 processors supposedly had a 128 Mb address limit for UEFI firmware. It sounds suspect, but looking back at early AM4 boards, I don't recall any with either 256 Mb chips or striped 128 Mb chips, so maybe it wasn't simply due to the significant jump in price for 256 Mb chips over 128 Mb ones.
Likewise, looking to replace my aging 7 year old HTPC with a mATX B550 and a Ryzen 4700G but radio silence from AMD on releasing compatiable APU's for the B550's, We now have the long overdue Budget motherboards but no APU's. Dissapointed.
I understand the frustration however if your buying a Budget Board then surely a budget CPU is the best fit, also new APUs are inbound according to all the rumours, meanwhile your older APU will fit just fine I believe, I expect the new APUs will have Navi cores as per the Xbox and PS5 but of course they probably cannot be released until the new Navi cards and consoles are out, think about it though what a sea chamge folks are now waiting eagerly for a new release from AMD because they know it will kick ass not close the gap to Intel, its a good time to be a customer!
Interesting that the GIGABYTE B550 Vision D board's Type-C ports don't have the Thunderbolt logo next to them. I wonder if Intel won't all the logo to be use on AMD systems.
"Although on paper, there isn't much difference between B450 and B550 with slightly more SATA available due to the removable of eSATA support, both remain PCIe 3.0 bound."
The B450 only had PCIe 2.0 lanes. Huge difference from the B550 IMO
Agreed. That's going to make a huge difference for boards with secondary or tertiary M.2 or U.2 ports that hangs off the chipset. That goes double if they only get 2 PCIe lanes instead of the full 4.
This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots. It seems that motherboard makers are totally f up(sorry for the expression) the more reasonably priced models in that area.
Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.
Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks!
Colour me disappointed. I was hoping to do a mATX file server build using an APU. No support for existing APUs, no ETA on when consumers can buy the newer APUs, and most of these boards only have 4 SATA ports.
I really don't want to have to buy a crappy NVIDIA 710 just to get it running.
If you're booting Linux, you might be able to get away with either a good old fashioned serial cable (a lot of boards still have a serial port header) or a USB-HDMI/VGA dongle, since these are supported by the mainline kernel. The main issue might jus tbe getting the BIOS to boot your install media, but a serial port might work still here.
You could also just borrow a graphics card from any other system you own to do the initial install, and then let it run headlessly once it's up and running.
I am booting Linux, and have tried completely headless in the past. It's not really worth the trouble (especially if I need to quickly diagnose issues), I'd rather just buy the crappy GPU.
I'm probably missing something, but what's the point of including HDMI/DP/DVI outputs if the boards don't support APUs? Aren't you going to need to use the output on your dGPU anyway?
I appreciate the summaries on the last page, but wish it could be enhanced a bit. E.g. what's the cheapest board with 2.5G Ethernet? What are the cheapest boards in general? I probably wouldn't go with the cheapest one, but given the prices on a lot of these, it's likely I would choose one of the less expensive ones.
So checking my local store's inventory, they have 25 B550 boards in stock, of all varieties, but are completely sold out of both B450 and X570 (there are a few cheap A320 boards available as well, and nine TRX40 boards that start at $450).
Something tells me Ryzen 3000 chips have been selling quicker than the motherboard manufacturers can keep up, and maybe that's part of the reason B550 prices are starting out high. If they're selling out, it makes sense for them to start with a higher MSRP, which they can always lower if demand falls.
Unfortunately for AMD, if B450 doesn't come back in stock, that's going to hurt Ryzen 3000 sales. Intel mobo inventory is also a bit limited, but about half of the Intel models they offer are available, including some in that $75-$125 range, versus about 15% of the AMD models being in stock currently.
I think the delays are all shipping-related. It's affecting all computer parts, like power supplies, motherboards, and the like. I wish a bunch of the mfgs would just pool resources to buy dedicated air cargo flights; maybe pooling will mitigate some of the losses on the lower margin items.
Hmm, these seem mostly...pointless? More expensive than B450 by a lot, barely cheaper than the superior X570 boards (which have more PCIe lanes, more USB ports, etc)...these really need to be $50 cheaper across the (mother)board to make sense, IMO.
It is interesting comparing similar X570 and B550 models within the same brand (or subbrand like Asus ROG or Gigabyte Aorus). It really seems like pricing is VERY close between them.
Of course, if the VRMs are comparable, then for 90%+ of users, a X570 and a B550 are basically equivalent. In some cases it's almost like you're giving the user a choice between a newer B550 board with WiFi 6 and an older X570 board with AX but more USB ports or something, for within a few bucks of the same price (if you can find them at MSRP and in stock, which really has been an issue of late.)
I was looking at the boards on morning of Jun 16th. Very few B550 boards in stock (not too unusual so soon to release) and prices were high, in the range there just a few months ago I could have bought an X570 board. However, X570s were mostly out of stock everywhere I looked, and those in stick were generally pushing $300 USD or more. I suspect either manufacturing has not completely ramped up after COVID-19 in Asia, or that there is still a shipping back-load via ocean freight bearing ships between Asia and North America. Maybe if we ever see a return to a semblance. nce of normal, prices might lower and parts return to stock,
Right - In February I picked up an X570 board for ~$30 under MSRP, so equivalent B550 board (same OEM, same 'line') would actually be a few bucks more... but adds a Thunderbolt header, WiFi 6 and 2.5 gig Ethernet (in exchange for PCIe lanes/slots and USB ports, and a 2nd m.2 connector). In the end, I think the X570 was a perfectly good choice on sale.
I love that summary table. I wish it had an entry for “8 or more USB-A ports”. I actively use 15 on my desktop. The fewer PCIe cards and hubs needed, the better imo.
Thanks for giving detailed and, hopefully, correct information about the PCIe configurations on these boards. Unfortunately many of the motherboard manufacturers don't give that information, make the information hard to find, give wrong information, or some combination of the above with regards to PCIe configuration.
Out of curiosity, what happens when you put a pcie 3.0 x4 ssd in an x2 slot when the ssd's maximum read and write rates don't fully saturate x4? Is it just limited to the ~2GB/s bandwidth of the slot or does the ssd do something worse?
Yeah, it will transfer just a bit under 2 GB/s due to overhead. I had this same issue with my H97 board and my Samsung 970, so I opted to purchase a cheap M.2 PCIe 3.0x4 card. HD Tune showed an improvement, but not by much to notice much real world difference.
And here it is a couple of weeks after the 'release' and there are no boards (well, no mATX versions) to buy...unless you want to deal with the scalpers on NewEgg asking $25 to 35 over the regular price - oh, and BTW, they will ship/deliver in mid-July - AND I see no reviews or comparisons other than manufacturers' sites advertising for the B550 boards. The few articles I see are all based on the pre-release data and not from actual delivered, installed and tested MBs. Poor AMD hardware release, as far as I am concerned.
The second M.2 slot for the Aorus Elite seems to support PCIE3.0x2 instead of x4 stated in the review unless I read wrong. Could anyone else confirm? This is the swaying factor for me to lean towards the Mortar. Specs from Gigabyte website below:
Storage Interface 1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 2242/2260/2280/22110 SSDs: 3rd Generation AMD Ryzen™ processors support SATA and PCIe 4.0 x4/x2 SSDs 3rd Generation AMD Ryzen™ with Radeon™ Graphics processors support SATA and PCIe 3.0 x4/x2 SSDs 1 x M.2 connector (M2B_SB), integrated in the Chipset, supporting Socket 3, M key, type 2242/2260/2280 SSDs: Supporting SATA and PCIe 3.0 x2 SSDs
Almost all of the boards include PS/2 connector. Why they put it in 2020? They stopped making PS/2 devices 15 years ago. Better would be to have an empty space there.
Hey, so is there any cheaper alternative to the Aorus 550M Pro with similar or better feature set? I'm in the middle of building a Ryzen system with 3300X and motherboard is the last thing I need to decide on. Other mATX at the same price or cheaper just don't look as good as the B550M Aorus Pro.
I need help..the mob manual says the m.2 slot for the chipset suport sata n pcie 3.0x2..but this review says it suport pci3.0x4..i bought a samsung 970 evo with a pcie 3.0x4..can it be used in the slot
Help me..i cant understand which one is true..the 2nd m.2 slot for chipset runs at pci3.0x4 or pcie 3.0x2(mob manual).and can a pcie3.0x4 be used in the slot
Question, is this board capable of overclocking and does it have a good power phase design? I was wondering because I want to build an all-white system but then came across another concern of this motherboard and that is if this supports BIOS Flashback feature so that I don't have to go out of my way to purchase an older gen CPU for it to support my 5900x
My personal computer running Debian has had four GIGABYTE B550 Vision D motherboards. The first and fourth had NIC initialisation on power up problems. The second one's NICs died after ~6 months. The third did not show voltage/temperature values properly. GIGABYTE warranty agents wrote "We do not give support to Debian OS".
how many usb ports are there to connect to the front of the case? (sorry if this doesnt make sense, im picking parts for a pc and a bit dumb when it comes to things like this)

The Asrock B550M Steel Legend has 8 port on the back:4x USB-A 3.1 ports
1x USB-A 3.2 port
1x USB-C 3.2 port
2x USB-A 2.0 ports
And you still have two USB 2.0 internal header, plus two USB 3.1 internal headers.
So that allows you to have another
4x USB-A 3.1
4x USB-A 2.0 ports.
so that's 16 Ports
Now if you like me and need Internal USB 3.2 USB-C header, you can use the PCIe 3.0 x2 m.2 slot to add one of these:
https://www.delock.de/produkte/S_63998/merkmale.ht...
or if you want two more USB 3.1 internal header you could add one of these:
https://www.delock.de/produkte/G_62843/merkmale.ht...
So if you can live without a second m.2 slot you have four more USB-A 3.0 ports.
That gives you 20 USB ports without giving up a PCIe slot.

My understanding is that the firmware size limit wasn't created by AMD. The motherboard makers could always use firmware chips with a larger capacity. Intel doesn't have this problem since they only support one or two CPU generations per motherboard :-)Lucky Stripes 99 - Tuesday, June 16, 2020 - link
I've read elsewhere that Zen1 processors supposedly had a 128 Mb address limit for UEFI firmware. It sounds suspect, but looking back at early AM4 boards, I don't recall any with either 256 Mb chips or striped 128 Mb chips, so maybe it wasn't simply due to the significant jump in price for 256 Mb chips over 128 Mb ones.Redstorm - Tuesday, June 16, 2020 - link
Likewise, looking to replace my aging 7 year old HTPC with a mATX B550 and a Ryzen 4700G but radio silence from AMD on releasing compatiable APU's for the B550's, We now have the long overdue Budget motherboards but no APU's. Dissapointed.alufan - Wednesday, June 17, 2020 - link
I understand the frustration however if your buying a Budget Board then surely a budget CPU is the best fit, also new APUs are inbound according to all the rumours, meanwhile your older APU will fit just fine I believe, I expect the new APUs will have Navi cores as per the Xbox and PS5 but of course they probably cannot be released until the new Navi cards and consoles are out, think about it though what a sea chamge folks are now waiting eagerly for a new release from AMD because they know it will kick ass not close the gap to Intel, its a good time to be a customer!Gigaplex - Wednesday, June 17, 2020 - link

"Although on paper, there isn't much difference between B450 and B550 with slightly more SATA available due to the removable of eSATA support, both remain PCIe 3.0 bound."The B450 only had PCIe 2.0 lanes. Huge difference from the B550 IMO
Lucky Stripes 99 - Tuesday, June 16, 2020 - link
Agreed. That's going to make a huge difference for boards with secondary or tertiary M.2 or U.2 ports that hangs off the chipset. That goes double if they only get 2 PCIe lanes instead of the full 4.a5cent - Friday, June 19, 2020 - link
Yup, exactly what I thought.Equally "BIG" is that B550 finally has more PCIe lanes, so adding more NVMe drives doesn't require downgrading other ports like it always did on B450.
B450 was a firmware upgrade for the budget B350 chipset. B550 is the first time this tier of AMD chipset doesn't suck.

This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots.

Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks!mrvco - Tuesday, June 16, 2020 - link
I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit.Kougar - Tuesday, June 16, 2020 - link
Most of these boards are a serious VRM upgrade over the B450 boards. If I was buying Ryzen right now I'd easily go B550 over X570.So, only the ASUS boards offer bios flashback? Seems like a cheaper, just as userful version of dual BIOS anyway.

Colour me disappointed. I was hoping to do a mATX file server build using an APU. No support for existing APUs, no ETA on when consumers can buy the newer APUs, and most of these boards only have 4 SATA ports.I really don't want to have to buy a crappy NVIDIA 710 just to get it running.
mm0zct - Wednesday, June 17, 2020 - link
If you're booting Linux, you might be able to get away with either a good old fashioned serial cable (a lot of boards still have a serial port header) or a USB-HDMI/VGA dongle, since these are supported by the mainline kernel. The main issue might jus tbe getting the BIOS to boot your install media, but a serial port might work still here.You could also just borrow a graphics card from any other system you own to do the initial install, and then let it run headlessly once it's up and running.
Gigaplex - Wednesday, June 17, 2020 - link
I am booting Linux, and have tried completely headless in the past. It's not really worth the trouble (especially if I need to quickly diagnose issues), I'd rather just buy the crappy GPU.IBM760XL - Tuesday, June 16, 2020 - link
I'm probably missing something, but what's the point of including HDMI/DP/DVI outputs if the boards don't support APUs? Aren't you going to need to use the output on your dGPU anyway?I appreciate the summaries on the last page, but wish it could be enhanced a bit. E.g. what's the cheapest board with 2.5G Ethernet? What are the cheapest boards in general? I probably wouldn't go with the cheapest one, but given the prices on a lot of these, it's likely I would choose one of the less expensive ones.
Gigaplex - Wednesday, June 17, 2020 - link
They will support the Zen 2 APUs, which aren't out yet.IBM760XL - Tuesday, June 16, 2020 - link
So checking my local store's inventory, they have 25 B550 boards in stock, of all varieties, but are completely sold out of both B450 and X570 (there are a few cheap A320 boards available as well, and nine TRX40 boards that start at $450).Something tells me Ryzen 3000 chips have been selling quicker than the motherboard manufacturers can keep up, and maybe that's part of the reason B550 prices are starting out high. If they're selling out, it makes sense for them to start with a higher MSRP, which they can always lower if demand falls.
Unfortunately for AMD, if B450 doesn't come back in stock, that's going to hurt Ryzen 3000 sales. Intel mobo inventory is also a bit limited, but about half of the Intel models they offer are available, including some in that $75-$125 range, versus about 15% of the AMD models being in stock currently.

I think the delays are all shipping-related. It's affecting all computer parts, like power supplies, motherboards, and the like. I wish a bunch of the mfgs would just pool resources to buy dedicated air cargo flights; maybe pooling will mitigate some of the losses on the lower margin items.Oxford Guy - Tuesday, June 16, 2020 - link
"Most of these boards are a serious VRM upgrade over the B450 boards. If I was buying Ryzen right now I'd easily go B550 over X570."Why does that matter? Overclocking died with Zen, especially Zen 2.
As long as it doesn't throttle, you're good.
althaz - Wednesday, June 17, 2020 - link
Hmm, these seem mostly...pointless? More expensive than B450 by a lot, barely cheaper than the superior X570 boards (which have more PCIe lanes, more USB ports, etc)...these really need to be $50 cheaper across the (mother)board to make sense, IMO.sing_electric - Thursday, June 18, 2020 - link
It is interesting comparing similar X570 and B550 models within the same brand (or subbrand like Asus ROG or Gigabyte Aorus). It really seems like pricing is VERY close between them.Of course, if the VRMs are comparable, then for 90%+ of users, a X570 and a B550 are basically equivalent. In some cases it's almost like you're giving the user a choice between a newer B550 board with WiFi 6 and an older X570 board with AX but more USB ports or something, for within a few bucks of the same price (if you can find them at MSRP and in stock, which really has been an issue of late.)
[email protected] - Wednesday, June 17, 2020 - link
I was looking at the boards on morning of Jun 16th. Very few B550 boards in stock (not too unusual so soon to release) and prices were high, in the range there just a few months ago I could have bought an X570 board. However, X570s were mostly out of stock everywhere I looked, and those in stick were generally pushing $300 USD or more. I suspect either manufacturing has not completely ramped up after COVID-19 in Asia, or that there is still a shipping back-load via ocean freight bearing ships between Asia and North America. Maybe if we ever see a return to a semblance.nce of normal, prices might lower and parts return to stock,
romrunning - Wednesday, June 17, 2020 - link
Shipping is main culprit here - big problem, including extra time spent in customs at ports (like LA in the US).sing_electric - Thursday, June 18, 2020 - link
Right - In February I picked up an X570 board for ~$30 under MSRP, so equivalent B550 board (same OEM, same 'line') would actually be a few bucks more... but adds a Thunderbolt header, WiFi 6 and 2.5 gig Ethernet (in exchange for PCIe lanes/slots and USB ports, and a 2nd m.2 connector). In the end, I think the X570 was a perfectly good choice on sale.willis936 - Wednesday, June 17, 2020 - link
I love that summary table. I wish it had an entry for “8 or more USB-A ports”. I actively use 15 on my desktop. The fewer PCIe cards and hubs needed, the better imo.GNUminex_l_cowsay - Wednesday, June 17, 2020 - link
Thanks for giving detailed and, hopefully, correct information about the PCIe configurations on these boards. Unfortunately many of the motherboard manufacturers don't give that information, make the information hard to find, give wrong information, or some combination of the above with regards to PCIe configuration.Out of curiosity, what happens when you put a pcie 3.0 x4 ssd in an x2 slot when the ssd's maximum read and write rates don't fully saturate x4? Is it just limited to the ~2GB/s bandwidth of the slot or does the ssd do something worse?
Lucky Stripes 99 - Wednesday, June 17, 2020 - link
Yeah, it will transfer just a bit under 2 GB/s due to overhead. I had this same issue with my H97 board and my Samsung 970, so I opted to purchase a cheap M.2 PCIe 3.0x4 card. HD Tune showed an improvement, but not by much to notice much real world difference.Allan_Hundeboll - Wednesday, June 17, 2020 - link
