Gigabyte MJ11-EC1 EPYC 3151 Mystery

[Th0mas51]

FYI, the following RAM are working fine:

- Samsung 8GB DDR4-2133 RDIMM PC4-17000P-R 2Rx8 (M393A1G43DB0-CPB)
- SK Hynix 32 GB DDR4-2666 RDIMM PC4-21300V-R 2Rx4 (HMA84GR7JJR4N-VK)

I have problem with getting working RAM for this board.

...

Can anyone share their RAM configuration ? I wanted to go with 2x32GB for my needs.

See above for my 2x 32 GB RAM config.

You have been populating the blue slots first, right ?

Some got bifurcation working on this board?

At least with the EC1 it seems to work, following the users guide. Could it work with the EC1 Bios?

Change the PCIe lanes.
Options available: Disabled, Auto, x16, x8x8, x8x4x4, x4x4x8,
x4x4x4x4. Default setting is Auto.

FWIW I requested the GPL source code for the BMC running on this motherboard and Gigabyte are refusing to provide it:

For those interested, I just ran a CPU benchmark and then a 15 minutes stress test using CPU-Z.

I'm running with hyper-threading enabled in the bios (so 8 threads), 2x8 GB of Ram, Windows 10 on a USB disk, and using the stock cooler but with new thermal paste.

The results are visible here: AMD EPYC @ 2898.29 MHz - CPU-Z VALIDATOR

According to Core Temp, the max temperature was 50°C and the power consumption of the CPU was 29.7 W.

Did you use stock fan and how was the noise?
