MemTest86 6.2.0 issues in parallel mode and certain CPU cores

[jbhelfrich]

So a final update from me on the issue: I wasn't able to get the BIOS version to run; while the motherboard does have legacy BIOS support, it seems it checks all of the UEFI options before it checks for legacy boot options. So the only way I'd be able to test it would be to remove the boot managers, which is a bit more involved than I care to get at this point.

Hi,

I'm having the same issue, i.e. Memtest freezing when run in UEFI mode on multiple cores on an AMD 970 chipset based motherboard. I have reached out to Gigabyte - my motherboard's vendor - about this issue, and once we clarified how to run memtest, they were able to reproduce the issue on multiple 970 chipset motherboards.
Based on my investigation what happening is that the whole south bridge is freezing or dropping out during some USB operation, but I can't determine more as the logging stops to the USB drive when the SB becomes unresponsive. Gigabyte is saying, that memtest is incompatible with these boards, as the issue does not happen on Intel setups.
The issue is quite simple to reproduce: start memtest 6.2 on anything else then core0 on an AMD 970 based PC with test 3, and it will immediately hang.
I think this is some firmware issue, as similar freezes happen under Windows too, just there it is a random thing, while with memtest it can be easily reproduced.
Is there any way to write any logs to the screen, as it seems the issue is limited to the south bridge, and NB connected peripherals like the screen, continue to work?

I had a similar experience leaving it to run last night, EFI v 2.31, set on round robin and test 5 x500. It completed 10x test 5 and then froze as it was switching to CPU 1, see penultimate line. Was unable to access the interface at all (esc had no effect). The last line below is the first line after a reboot to restart the program, which worked OK.

FYI was not able to upload the log or the zip of the log to the BB for unspecified reasons. Have had to truncate the text due to the BB message length limit.

Thank you, asterx! I'm glad some motherboard manufacturer actually wants to try things for themselves. ASRock's tech support just kept insisting that the SMT mode is an option and that it should be disabled, because according to some forum posts this has caused issues...

Sylvester, could you share your system specs?

[Sylvester]

Sylvester, could you share your system specs?

Sure.

Mobo: Gigabyte GA-Z97MX-Gaming 5 (1.0) BIOS:F4
VGA: GTX 770 (GV-N770OC-2GD)
OS: Win 7 Ult x64 SP1

[asterx]

It was not easy to get this far with the vendor, so it would be good now, if the Passmark team would reply something on how to proceed, as now the vendor is pointing on memtest incompatibility. (Which could be the case, as now it seems the issue is happening with Intel boards too.) Is it possible that the AMD and Intel boards share some basic UEFI / BIOS code that could be causing the issue?

[asterx]

Hi Sylvester,

could You please open a support ticket with Gigabyte about the issue?

[Sylvester]

Are you saying you think the bug is due to a flaw in the BIOS programming?

Unfortunately I am currently using the F4 BIOS which is not the most recent BIOS. So I would be wasting eveyone's time if I did that asterx.

I am not willing at this point to upgrade the BIOS to the latest F6 because once upgraded it cannot be flashed back to F4. I have been discussing this with Gigabyte already due to the bunch of different BSODs I have been trying to track down.

Sorry but you are not able to revert to F4 after updated to F6. You may return the board to us if you want to revert to F4 BIOS.

Why not you give a go update to the latest F6 BIOS to check it helps?

This board has a backup BIOS system which is set to F4 BIOS and cannot be user upgraded.

Which means if the F6 has a problem, I cannot flash it back to F4 or recover it with the backup BIOS which may have automated aspects and could end up hosing the BIOS. So I may have to send the board away to get it fixed, not a risk I am willing to take unless I absolutely have to.

Currently the single core memtest seems to suggest that the source of the BSOD is the RAM. If true this means I wont need to update the BIOS to fix the BSOD, just fix the RAM.

Sylvester,

Did you try other CPU modes such as Parallel, Sequential or CPU1 in single mode?

We are trying to gather information to determine if it the issue described by OP is exclusively on AMD CPUs, or is a similar but different issue on Intel chips.

[Sylvester]

Keith, no I hadnt but I just did a quick trial, using tests 0,1,2 and managed to get it to lock up on Sequential if that is any use. It seemed to have no problem with Parallel or CPU1 and I could not replicate Round Robin, not sure if the test types make a difference?

Here is the test start to the end of the log.

Thanks for that. The problem appears to manifest when the CPU is cycled from 0 -> 1 -> .... 7 -> 0 -> 1. We have seen this issue on other boards as well (in one case, the vendor contacted us directly to help them debug the issue). This particular issue, however, seems to be different from the previously described AMD issue.

I'm having a similar issue which in my case is definitely UEFI related somehow.

Board: Asrock 970 Extreme3 R2.0
CPU: AMD Phenom II X2 550

When booting memtest using UEFI (i.e. run memtest v6) and run just on Core 0 it runs without error.
If I try to run single on Core 1, it immediately freezes.
Also if I try parallel, round robin or sequential, it consistently freezes as soon as it goes to run a test on Core 1.
Interestingly, if I boot memtest without using UEFI (i.e. it loads memtest v4) I can run parallel without error.

Grum, do you konw what BIOS firware version you are running?
I have added this system to the list of known bad systems.

1.60

There is one later version on the Asrock site but the description only says 'Add warning message when unsupported CPU installed' so I'm not expecting any change if I did update.

Edit: I just updated to the latest bios version (2.20) and it's still the same. Memtest v6.2.0 freezes immediately when using Core 1 but memtest v4.3.7 is working fine using parallel.

Millions errors

Hi, i have similar problem. logs and html attached
iam using v 6.2.0
https://drive.google.com/file/d/0B1Z...ew?usp=sharing
https://drive.google.com/file/d/0B1Z...ew?usp=sharing
sorry, i cant attached files in your file uplod( iam using google drive.
in single CPU mode pass 1 run without any errors.
in multiple CPU mode i have a lot of same errors in test 3. Than i stopped test.
Iam trying to change ram slot, it didnt help.
May be i need to test RAM with lower version of Memtest?
The reason for test is that i have problem like irql_not_less_or_equal, iam not writing code of error =( and i cheked HDD. HDD is OK.
PS. sorry for my eng =)
