List of Motherboards with issues when running MemTest86 in multi-CPU selection modes

[sugob]

Hi

[this thread (although old) seems similar i.e. "Hang on MemTest86 startup during multiprocessor test" so hopefully ok to post here]

When booting [USB] MemTest86 [v8.40 free] to test my new rig, it seems to hang during the startup multiprocessor test -

Processor: AMD Ryzen 3700X [8 core]
MB: ASRock X570 Phantom Gaming-ITX/TB3 i.e. AMD X570 chipset. UEFI v1.70 09/11/2019
RAM: 32GB OLOy 3200MHz 16-20-20-38 [2 sticks, 64GB total]

I tried adding this MB to the blacklist but now MemTest86 startup hangs showing 'Getting memory controller details...'

Everything running stock i.e. no overclocking etc. Windows 10 installed with no issues - task manager shows correct CPU & cores, memory etc

I have attached the MemTest86.log [I tried to cut out the entries for 2 failed boots - one before and other after I added MB to blacklist]

TIA for any help/clues

Cheers
M

Hello,
I ran the latest version of Memtest86, and it would hang on the Multiprocessor Test as well.

• Motherboard: ASUS Crosshair V Formula Z
• BIOS: 2201 03/23/2015 -- Was the last release of BIOS for this board
• CPU: AMD FX-8120, 8-Core Processor, 3.10Ghz
• RAM: 4x 8GB G.Skillz Tridentz DDR3-2400 PC3-19200 10-12-12-31 (Wanting to test these).

Thanks for letting us know. Can you attach a copy of the MemTest86.log file located under EFI\BOOT\ of the USB flash drive.

We will add the board to the blacklist.

Hello ,
when Memtest86 starts, the program hangs at 0:00:04.
Pass: 16% Test: 0%.

• BIOS version: 2.08 (06/28/2019)
• CPU: Intel Core i7-5820K

ASUS has fixed the firmware on some of it's motherboards. See the red text in the 1st post of this forum thread.
From the limited contact we have had with ASUS it seems they don't consider it a big enough problem to systematically fix all their boards. Very likely you will be ignored unless you are planning on purchasing 1000s of boards from them.

• Motherboard: ASUS PRIME X370-PRO
• BIOS version: 5220 (2019/09/24)
• CPU: AMD Ryzen 5 2600

MemTest86 v8.2 Free tells me "**Warning** Your UEFI firmware has limited multiprocessor support" when I go into CPU Selection.

Is there any additional information I can gather to help with support for this motherboard, or to help encourage/enable ASUS to make fixes?

@keith here is the log attached

Thanks for that. There appears to be a bug with the UEFI firmware's multiprocessing subsystem as shown in the following log entries

2018-10-22 14:48:05 - MPSupportTestMPServices - CPU #31 completed but did not signal (event wait time = 1337ms) 
2018-10-22 14:48:05 - MPSupportTestMPServices - AP dispatch test complete
2018-10-22 14:48:05 - MP test failed. Setting default CPU mode to SINGLE

We have added the baseboard to the blacklist to prevent it from running in multithreaded mode (until MSI is able to provide a fix)

• CPU - AMD Threadripper 1950X
• Summary of the issue you are experiencing - freezes in parallel mode on test 3 (2?)

Thanks for that, we have updated the list. Do you by chance still have the MemTest86.log file for the machine (located under EFI\BOOT of the USB flash drive). If so, can you upload or e-mail to us.

Are there issues with new AMD Threadripper 2nd gen CPU's (2950x)?

We aren't aware of any issues. But we don't have a 2950x to test with yet either. Send us the debug log file if you want.

Are there issues with new AMD Threadripper 2nd gen CPU's (2950x)? Running memtest86 Pro 7.5 build 1001 and no multicore support, only 1 thread active on test 7 (moving inversions). Asrock Taichi X399 mainboard with L3.32 BIOS. Multicore support was working on the same board when I had TR 1950x installed.

iz1016,
Thanks for the information.

Hello,

Tried running memtest86 7.5 on Asus Strix X370-f with BIOS version 4012 and it booted into V4. When I launched into partition with V7.5, it would load without multicore support.

I looked at the blacklist in the UEFI file and see that this board is listed there but it isn't listed here. I'm just wondering when it was added and what specific issue it had? I tested using memtest86 a couple of weeks ago and it seemed to work fine (although for whatever reason, I can't find the USB I had it on and can't remember the version of memtest86 it had on it). Is this a newly reported issue?

I removed from the blacklist file and so far it appears to be running ok on my system.

Thanks
