    Finally: Overclocking EPYC Rome ES

    Thanks for replying, I not so sure that if my 6800xt is connected to this GPP Bridge, but the error is gone when I force the pcie runs at gen3 in bios. So there maybe some problem with pcie gen4.

    Finally: Overclocking EPYC Rome ES

    Hi, got a 7452QS with EPYCD8 and 6800xt, GPUZ shows that PCIE runs at Gen4, but there comes a lot of PCIE error in windows event, so question is if there is anyone use the 7452QS with PCIE Gen4 runs well without pcie error? Thanks

    Asrock wont support EPYC Milan on the EPYCD8/EPYCD8-2T

    Just a thought, maybe we could try to cross flash the bios of ROMED8 to EPYCD8, to see if it could boot, with the build-in Dr.Debug, maybe we could figure out how to get milan work on this board.

    Maybe there are some internally freq throttling, I see the freq is constantly 3.45G@1.05v

    I have and 32c 57-04 qs, and the VID is 1.26v+ in 3.45G. When I manually set the voltage to 1.05v ,the cinebench r20 score is lower than 1.26v+, even lower than 3.0G.

    Hi guys, I recently purchase a 7452 QS 57-04 on EPYCD8, 8x16GB 2400. And I found that some temperature in HWInfo64 was ridiculous high: As you can see that "CPU Die (average)" was around 72°C and when I run the Prime95 torture test it'll quick raise up to 100°C (TjMax), but the CCD temp seems...

    Can anyone tell me what is EPYC 7D12

    emmmm, maybe you are right, they will check the entire BIOS image to build a trusted root

    Can anyone tell me what is EPYC 7D12

    Or maybe we could extract the PSP fw from dell and then plant into our custom bios, but this base on the hypothesis that there is not any bios signed/verify procedure in EPYC boot

    Can anyone tell me what is EPYC 7D12

    See through the article, I figure out that: 1. AMD has implement some mechanism that allow server vendor like DELL to install a public key into PSB (Platform Secure Boot), and then the system will only boot with the firmware signed with corresponding private key. 2. PSB (Platform Secure Boot) is...
