Both those kits will do 3800c14 at or below 1.5V


I have a friend on another discord that RMA'ed his Unify-X because of this problem you're reporting.
I would suggest doing the same.
I wrote a support ticket with MSI support. Lets see what they have to say about it. I can not believe that it is a hardware defect of any sort. Just some BIOS setting or mess up on MSIs part. Also wrote to AMD about it, in case it has something to do with AGESA (do not believe this, but still possible).
 
Hello all,

Looks like today MSI released "stable" BIOSes with AGESA 1.2.0.3b for both boards, replacing the previous beta ones on the Support pages:

Version: 7D13v13
Release: Date 2021-07-05
Description: Update to AMD ComboAM4PIV2 1.2.0.3b

Version: 7D13vA3
Release: Date 2021-07-05
Description: Update to AMD ComboAM4PIV2 1.2.0.3b

I haven't tried to flash my Unify non-X yet, will try to share impressions once I do. :)

The release dates are strange. Also the version is A30 while their most recent beta bios is A32
 
Guys can you test your nvme drivers on this board?

This is my ADATA SX8200 PRO GEN3 1TB bought 1 year ago before the NAND fiasco.

It's rated at 3500/3000 which worked fine on my B450 board as you can see here:

2518612


This is on the Unify-X

Running from CPU:

2518611


Running from the chipset:

2518613


Clearly the drive is good so the issue lies with the board and it's terrible PCI-E layout...
Would love to see your own testing.
 
You can't compare speeds at different drive capacity usage.
@weleh still has ~50% disk free, would that degrade the write speed that much? :unsure:

Anyway, here's mine with the exact same NVME drive:

Rectangle Font Screenshot Technology Parallel
 
Anyway, someone else run crystalmark to check performance.
I attached a CrystalDiskMark screenshot in my post above. If there are no fundamental differences in PCI Express layout between the Unify-X and non-X, your theory here doesn't seem to hold water:

so the issue lies with the board and it's terrible PCI-E layout...
 
For the chipset I used M2_2, it was just to rule out issues with the drive itself (second picture).

The drive is ran on M2_1 as it's supposed usually (first picture).

Now the question is, can I run CPU mode on M2_2 and keep PCI_E1 at x16? Or does it automaticaly go to x8 even if M2_1 is unpopulated? Just to confirm it's not the drive slot that's ****ed?

Only one besides M2_1 that is full x4 without downgrading PCIE x16 slot is the bottom one from PCH M2_4 which is gen3.

I went ahead and tested on mine which only has 10GB used on my SN750 but results are:
M2_1 run1: 3420/3113
M2_1 run 2: 3433/3109
M2_2 cpu: 3435/3092
M2_2 pch: 1786/1691
M2_3 cpu: 3434/3108
M2_3 pch: 1787/1706
M2_4 3396/3110

I used fresh crystal disk mark from the download site ver 8.0.4 x64, set 1 run of 1GiB like in your photo.

Odd thing was when I switched M2_2/M2_3 from CPU back to Chipset, I had to remove the drive for it to detect it again in slot 3. Not that big of a deal just kind of weird. I ran test from first M2_1, M2_2 pch, M2_2 cpu, M2_3 cpu, M2_4, M2_3 pch, M2_1 test 2 last.

Mine doesn't appear to have issue with the M2_1 slot. If you don't have a 2nd drive to try in M2_1 slot then RMA I guess is only option. It is pretty weird because you get full read speed of gen3 but the write is messed up so the link speed seems to be fine.

Many thanks for your testing!
Since my drive is Gen3 I'm not bothered about Gen3 vs Gen4, all I want is x4 full speed.
I'll test the M2_4 to see if it's a problem with M2_1.

Again, many thanks!
