I will be adding to post 1 information concerning conventions I'm seeing in varying manufacturer 290 / 290X roms to set the DPM 0 -7 Freq.



On the left is table for Stock AMD R9 290X bios, middle is Vapor-X R9 290X STD Edition and right is the Vapor-X 290X OC Edition.

When manufacturers create a OC bios GPU Freq for DPM 0 & 1 will always be 300 MHz & 516 MHz . DPM 2 -7 will be the percentage shown of DPM7.

For example if I was setting GPU clock as 1100 Mhz then DPM7 would be this then DPM 6 would be 1100 x 97.7% = 1074.7 (rounded up to 1075) .

RAM Freq DPM 0 is always 150MHz and DPM1-7 are full RAM speed.

It looks like I've got the GPU core voltage offset mod I was after! biggrin.gif

My stock bios offset of +31mV was not enough to get me 1100MHz / 1525MHz , but now with the bios set to +44mv!

Will be adding info to post 1 after some more testing! smile.gif .

Thanks for this guide, i've tried to modify the temp and rpm values of the bios of my r9 290 vapor-x OC, to stop the fans in idle, but it didn't work. There are some other value to modify to have full controll on the rpm and stop the fans?

No idea, sorry.

On my Vapor-X 290X it has a switch to enable outer fans to stop spinning at low gpu usage.
Warning: Spoiler! (Click to show)



Your Vapor-X 290 also has this feature / switch.

Thanks for reply, i know i can stop the external fans, but even with only one fan spinning, the gpu is more noisy of all my system. I've set the first rpm to 0 in the bios and in the catalyst i can see fan speed 0% but the fan still spinning at 20%, i've tryed to modify the fan speed with MSI Afterburner, speedfan and sapphire trixx, but didn't work. I suppose there are some other values to set min rpm to 0, or to control the fans separately but i can't find them anywhere.

Tried a test in VBE7 to see what values change on a 7970 rom when fan profile edited to have minimum of 10% and it changes %rpm1 hex values that are in the fan profile editing in post1. As some things in post one where sussed by doing this and checking for comparable in 290 / 290x rom.

Those values you've edited anyhow, so like you would think there is a setting in bios which forces a minimum of 20%.

Difficulty in searching the rom is it could be a D0 07 you're looking for or a 14.

I too have tried setting MSI AB , Sapphire TriXX to lower % but it doesn't work.

*** edit ***

To all other viewers in further testing phase for voltage editing to bios and will soon be adding information to post 1.

Got a 290 trix a few days ago and planed to under-volt it.
After reading a bit it seemed that all AMD bioses are locked via signature. Later I found out that was not the case anymore for the Hawaii chips. Just to then find out that there is no bios editor out for it... oh well

Seems you could become my savior just in time. biggrin.gif


All the tools like Sapphires Trixx kind of work to test voltages and gpu/ram clock. But they have to many quirks for me and I also use the GPU under Linux.
The idle status seems to be my current unvervolt limit for the ram when working with offset voltage. I guess that has to do with the ram speed being at max for anything except the lowest power mode.

With trixx I'm currently running 1000/1200 with -75mv (native this card runs 1000/1300 + 12mv)

I am curious how far I can undervolt with full access to the dpm tables!
