DDR4 SPD Bank switch not working on TRX/Threadripper #123

Open shr-project opened 2 years ago

shr-project commented 2 years ago

The frequency seems correct for my TRX3970, but the Memory throughput looks very wrong (~600MB/s instead of ~15GB/s) aand sometimes it detects used XPM 3200Mhz correctly and sometimes it shows 2666Mhz.

Screenshots are from beta2, but the same is reproducible with beta3 as well (official release build as well as locally built with gentoo).

x86fr commented 2 years ago

The XMP detection issue is a ASUS-specific bug with some latest BIOSes they released. It's a race condition on the request sent to the SMB controller between Memtest86+ and an internal temperature check done by the motherboard. I must add a fix somewhere in the code to check if another request is processing.

The low memory bandwidth bug is due to the giant L3 cache. Bypassing or nullifying the effect of such a large cache to get the raw memory bandwidth is quite a challenge. The correct way to do this is probably to use MTRRs to set a memory area as non-cacheable, but it's not that easy on a multi-socket platform.

Same here, on TRX3960 MSI platform it 's saw 4 X DDR4-2400 ....??

OK, the bank switch is not working, preventing the correct reading for Vendor, SKU and XMP datas in Bank 2 while data in Bank 1 (capacity, Jedec speed, etc.) are read properly. It's probably not very complex to fix, but finding such a platform for debugging is the main challenge. I will ask the betatester team.
