Memtest86+ don't boot on MSI MAG X870E Tomahawk WiFi with 7E59v2A95 or 7E59v2A94 bios

Memtest86+ doesn’t boot when the BIOS version is 7E59v2A95 or 7E59v2A94. Both versions are probably pre-release BIOS builds with AGESA PI pre-1.3.0.0. After run Memtest86+, there’s only a black screen with a “-” on the left side, and nothing happens. On an older BIOS (two versions back) everything was OK with the same settings.

Tested with Secure Boot enabled and disabled on the motherboard, and with Ventoy configured with Secure Boot support enabled and disabled. Key certificate enrollment was done. I also tested different boot modes alternately. What’s strange is that it should start with UEFI + Legacy and Secure Boot disabled, but it still doesn’t work.

On the BIOS versions where it worked, I used Ventoy with Secure Boot support enabled, with the Memtest86+ image as a file on the Ventoy USB drive. Secure Boot was enabled on the motherboard, UEFI-only, with no CSM/Legacy.

Any report (working or not) on MSI motherboard will be greatly appreciated! Thank you!

It is working on my X870E Edge TI WiFi with the latest BIOS 7E59v1A82 with Agesa 1.3.0.0 and secure boot enabled disabled.

Thank you! I really don't understand what could be wrong here and how to fix that issue. I've carefully checked the whole changelog for AGESA1.2.7.1 and can't find any related change (a FWDEV or PLAT # could be helpful). "Self-modifying" code is of course used for relocation, but that's a mandatory root feature without any security drawback. Anyway, the BIOS just crashing/freezing without giving an error message is quite disturbing for users.

Check PM

I worked on a fix that seems to allow Memtest86+ to run on a Gigabyte board that previously freeze.

The PR has been pushed here if anyone want to look at the code : https://github.com/memtest86plus/memtest86plus/pull/604

I compiled a binary with this PR : https://memtest.org/download/beta/2026033104-mt86p-8.10-beta.zip
You just have to extract it (with the embedded /efi/boot folder structure) into a cleanly formatted FAT32 USB Flash Drive to try booting it (Secureboot must be disabled).

Any report (working or not) on MSI motherboard will be greatly appreciated! Thank you!

I tested iso x64 nightly 8.10 and all work now via Ventoy with memmode, but show 24°C on both DDR5 6000Mhz 30-36-36-76. That's too low?
Edit:
After end of test show properly temperature 35°C
