Description

Hello,
Before opening an issue on memtest issue tracker,
I would like to know if the DDR3 SPD reading is correct because with memtest 7.20 (64bit build),
the main screen is fully empty, instead of showing:

Memory SPD Information
----
- Slot 0 : RAM SIZE / SPEED / PART NUMBER
- Slot 1 : RAM SIZE / SPEED / PART NUMBER

Also, no mention of the RAM CAS just above. It is empty.
Otherwise the test is running correctly.

I'm having the same issue with a t400, r400 & t500 and memtest 7.20 (and earlier)
All my lenovo are running coreboot 24.12 and have CONFIG_DUMP_SMBIOS_TYPE17=y
Otherwise dmidecode have no issue reporting those values, see below.

Any advice appreciated. Thanks.

$ dmidecode -t 17
# dmidecode 3.6
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.

Looking at memtest86+ bug 2, it seems like they don't depend on the firmware for the SPD information, so I think this would be an issue with Memtest86+. I don't have any reason to think that the SMBIOS information isn't correct.

https://github.com/memtest86plus/memtest86plus/issues/2

I'm going mark this as resolved for now, but go ahead and reopen it if you have more information that points at coreboot being the issue.
