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

[EECS]

@David,

I reran the MemTest86 v8.4 Pro build version 1001 in Single CPU mode with the suggested CPU #1 (rather than CPU #0).

In this attempt, I tried limiting the DIMM count to 1 and I still encountered the hang.

The Supermicro BIOS version 2.1 was released 5 months ago (in February 2020).

I’ve attached the new log files with the corresponding screenshot of the last time updated. I am unable to post the other screenshot unless I create a double forum post.

EECS,

Others have reported similar problems with SuperMicro boards.

One suggestion was to change the CPU selection to CPU #1, instead #0.
We think their BIOS is buggy.

I am encountering hangs at around 1 hour and 30 minutes testing on Single CPU mode in version 8.4 Pro Build 1001. This issue continues to exist even after disabling SMT.

I installed Linux successfully with no issues and have not encountered hangs for days.

Motherboard: Supermicro H11SSL-NC R2.0 (BIOS version 2.1)
CPU: AMD EPYC 7302P 16C/32T@3.00GHz
RAM: Samsung M393A2K40DB3-CWE 16GB DDR4-25600 3200MHz

Attached log file and a screenshot of last time updated.

Also experiencing a hang during boot at "Testing multiprocessor support". Hang occurred in version 8.4, 8.4.1003, and 8.4.1.004; however, I was able to successfully boot with no issue on version 8.3 on the ASRock B450M PRO4.

I have two different systems that I have tried, the above was only tested on one system (ASRock B450M PRO4), but both systems experienced the same issues.

Thanks for the logs.

We found a memory related issue that may have corrupted the memory used by the UEFI firmware, which may have caused the hang in v8.4 but not in v8.3.

We have created a new thread to track the v8.4 builds and related issues.

Please give the build a try at your convenience.

I have two different systems that I have tried, the above was only tested on one system (ASRock B450M PRO4), but both systems experienced the same issues.

System One
=========
Motherboard: ASRock B450M PRO4 (BIOS VERSION 3.60 and 3.90)
CPU: AMD Ryzen 2700 (no overclock)
RAM: G.Skill 16GB DDR4 3200MHz F4-3200C16D-16GVKB (stock speeds, no XMP profile)


System Two
=========
Motherboard: ASRock B450M Steel Legend (unsure of BIOS version, will update later)
CPU: AMD Ryzen 3400G (no overclock)
RAM: Corsair 16GB DDR4 3200MHz CMK16GX4M2B3200C16 (XMP profile enabled)

Will upload logs for the second system when I get a change. I was also going to include the logs for the successful boot on version 8.3, but for some reason any USB created with the 8.3 image will not showing up in file explorer and therefore is inaccessible (diskpart shows the disk, but can open).

Yes. I mentioned that mouse works ok in BIOS and Windows 10

[David (PassMark)]

Logitech MX mouse is too smart for its own good.
Seems it is non standard and needs Logitech device driver to work correctly. What happens if you go into the computer's BIOS screen? Does the mouse work there?

Hi
Maybe I should add future comments to the other thread below as now reasonably sure my issue not due to Multi-CPU issues [I was just mislead by the screen messages]?
http://www.passmark.com/forum/memtes...et-screen-size

I thought I'd give my new computer a soak test with v8.3 anyway and it seems to run ok - 0 errors so far

A new issue is with my mouse [Logitech MX] - moving it 10cm moves the mouse pointer about 1mm on screen i.e. it does seem to move with mouse movements, just extremely low resolution.
This made the mouse pretty much useless so I had to use the keyboard [which is not the end of the world]
The mouse works OK when I used it when in the computer BIOS [or when boot up into windows], just memtest86 has issue

Hi
With 8.4 v1004, screen message still hangs at same point "Testing multiprocessor support..." [I left for 10mins] but the log gets very sightly further
2020-04-17 14:10:27 - [CONFIG] This platform has 16 logical processors of which 16 are enabled. # Log for v1003 used to end here
2020-04-17 14:10:27 - [CONFIG] SelCPUNo = 0
2020-04-17 14:10:27 - [CONFIG] CurLang = 0
2020-04-17 14:10:28 - [CONFIG] ConsoleMode = 0 (MaxMode = 4)

With 8.3, it seems to work - it [auto] went into a test
The equiv log for above shows
2020-04-17 14:29:08 - [CONFIG] This platform has 16 logical processors of which 16 are enabled.
2020-04-17 14:29:08 - Console size = 80 x 25
2020-04-17 14:29:09 - Screen resolution is too high (1920 x 1200). Setting screen size to the maximum 1920 x 1080
2020-04-17 14:29:09 - Unable to set screen size
2020-04-17 14:29:09 - Screen size = 1920 x 1200
2020-04-17 14:29:09 - Char width=8 height=19

Maybe the 'too high' resolution 1920 x 1200 is not being handled correctly by 8.4?

P.S. It would be convenient if app displayed to screen the version of software being run e.g. the same string as put in log file?
MemTest86 V8.4 Free Build: 1004 (64-bit)

Thanks

Thanks for the logs.

We added some more debug output, as well as disabled setting of the graphics resolutions. The screen may look off but hopefully it is a temporary workaround for the hang.

Please attach the logs if possible.

If the problem still occurs, can you also try the previous MemTest86 v8.3 release and see if the problem occurs as well:

Mine is hanging on Testing multiprocessor support... as well. I also just tried version 8.4.1003, but had the same problem. My log is attached.

Link with the space %20 has been fixed.
We'll take a look at the logs and get back to you.

[Chris Grant]

I'm also getting the hang on Testing multiprocessor support... I've tested with both the GA version and the version 8.4.1003. Please see attached log.

Cheers

Hi
Thanks for the quick response
I rewrote my USB SD card with your new 1003 version [i.e. my MB will not now be in blacklist] and it hangs in the same spot i.e. last entry showing on screen is 'Testing multiprocessor support..."

My monitor [ancient Dell 2407 - resolution 1920 x 1200] is attached to computer graphics card HDMI port [Radeon 5600XT]
I don't know if this is relevant, but the 9 lines of info [Starting "Retrieving hardware info. Please wait..."] don't start at top left of screen - they start about a third way down screen and a third of the way across from left

FYI: I also got the 404 downloading your link - seems there's an extra space at end. If copy link, shows as '%20' - if I stripped this off, then it worked
i.e.
https://www.passmark.com/temp/memtes...b-8.4.1003.zip%20

We suspect it might be related to this issue, which is related to setting the screen resolution.This occurs immediately after configuring the multiprocessor settings.

If possible, please upload the MemTest86.log file as before.
