Today, OhGodACompany releases it's VBIOS editing tools for AMD GPU's. This includes: OhGodATool: Edit PowerPlay in the VBIOS, or in the kernel's pp_table. This is for editing clock, memory, or voltage tables. OhGodADecode: Decode a strap's timing. A strap is the format of timing values stored in hexadecimal in AMD's VBIOS. OhGodACsumFixer: Corrects the checksum that is changed whenever you edit the straps. it does not fix the signing value. OhGodAnOffset allows undervolting on Linux - you tell the regulator what to do. It is a paid tool, and not publicly available. If you're interested in purchasing OhGodAnOffset, please send 1.5 BTC to 1buttzjpRmejg9iaZam8S9ugkkcP5dgbC. |

Great contribution to the community.
I am curious about the Offset Tool, does it add an offfset on the bios or is it a tool similar to Watttool

Just getting around to testing ohgodatool. So far I'm impressed; with this and rocm-smi it looks like I can do everything I could with fglrx/aticonfig.
If I had learned this tool last week when you released it, I could've had a much easier time testing memory straps. I used to change mclk in PBE, copy the BIOS file to my rig, flash, reboot, then test. Now it's just --mem-state 1 --mem-clock xxxx, and test the change.
And once I've found a stable mem clock, I can use it to mod the bios file without having to launch a windoze vm for PBE.
Thanks for releasing this!

While changing mclk works great, so far I've had no luck with voltage changes. They report as having changed, but power consumption does not change. I've tried changing individual dpm states to evv and fixed voltages - no effect. I've tried changing every state from 1-7, and still no effect. $ sudo ./ohgodatool -i 0 --show-core
DPM state 0:
VDDC: 800 (voltage table entry 0)
VDDC offset: 0
Core clock: 300
DPM state 1:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 466
DPM state 2:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 751
DPM state 3:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 1019
DPM state 4:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 1074
DPM state 5:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 1126
DPM state 6:
VDDC: 850 (voltage table entry 8)
VDDC offset: -26
Core clock: 1169
DPM state 7:
VDDC: 850 (voltage table entry 8)
VDDC offset: 0
Core clock: 1216

Still not possible? Any update on this? Ethos/Hiveos as main linux distros seems still have the problem to set undervolt, and can only set DPM  |
