Finally: Overclocking EPYC Rome ES

[Frk]

Just a small update on my attempt to rewrite @Zhang ZenStates Linux version with support for dual-socket mainboards to use SMU instead of MSR; I’ve got it somewhat working—thanks to Claude Sonnet 4, but it still needs more testing and fine-tuning before I can release the code. Here's a PassMark test running on Proxmox VE 8.4, overclocked to 3 GHz:

Did you try this? That's the only version I remember seeing with amd CBS menu

edit: if someone would be able to apply that fix to the 2.1 or 2.0b bios that would be sweet. 2.0 missing all the fixes for nvme etc.

Am I correct in understanding that the onboard NVMe ports on the H11DSi-NT are not functional with the (modded) BIOS version 2.0? I’d appreciate any additional information on this, as it would help me avoid potentially purchasing cables and drives that I can't use or return.

Thanks!

they are direct outputs from CPU2 PCIe ports, with correct bifurcation they should work.

I am too bad in English, so not able to read all of 49 pages.
I tried to upload Rome_H11DSI_Rev2 BIOS into my H11DSI motherboard and there is an error: 38-Error. Milti Tank ROMs' ROM ID are not allowed the same. What should I do?

Is the improvement only for dual-socket?
Can you post a link to the binary so I can test it on mine? I have a single 100-000000053-04.

Please help me...

you normaly run flash.nsh
multi tank is if the BIOS is Naples/Rome(32mb)
if your mobo has 16mb chip you need SPI flasher and test-clamp

My motherboard has 32mb chip.

My motherboard has 32mb chip.

read the readme for H11, how to update bios.

read the readme for H11, how to update bios.

The main idea is format USB flash as FAT32 and run
fs0:\ flash.nsh BIOS.FILENAME

But after makin this I see:

This continues again and again. I think it means the problem is inside the file.

don't know what's inside your BIOS.BIN
and i never updated BIOS with Afu tools, i use BMC/IPMI all the time,
especially modified BIOS do not work with AFU.

This is the file "Rome_H11DSI_Rev2" from the 1st post in this topic. I have just renamed it.

Does not work on my board. Needs signed BIOS an can't pass the secure validation.

not valid BIOS can't even flashed with AFU.
you need SPI flasher with SOIC test-clamp (or soldering)

Anybody flashed midified BIOS without SPI flasher?

works normaly with old BMC Firmware, if you update to latest it accepts no unsigned firmware.
all BIOS here are from times before new BMC Firmware with protection.

I've bought 2 boards with new firmware. Is there a possibility to downgrade?

 

[RolloZ170]

Is there a possibility to downgrade?

afaik only with SPI programmer.

Any update on this? I would also love to test this. I have 2x systems one w/ (H11SSL and single 100-000000054-04) and another (H11SSL and single ZS1711E3VIVG5)

Reporting back on Epyc Milan ES 64c 100-000000425 -3.7Ghz & Asus KRPA-U16

Release MilanOverClock · SKlayer/EPYC-Overclock

This does seem to work on changing freq
Vcore however does not, getting 1.3xV on 4.2Ghz, 32cores/8ccd/HT-off, 400w+ CPU/550+ at the wall
EDC limit also seems to do something
Also, L3 cache speed is halved when changing freq

Hello
I've bought SPI flasher and want to flash my H11SSL-i with custom BIOS. What should I do?
How can I find BIOS chip? There are too much 8pins chips.
