Overclocking GPU in Ubuntu?

post #1 of 6
Thread Starter 
Hey guys,

I'm currently in the process of setting up a folding rig with an MSI GT430 and an undetermined Athlon X2 (I pulled this from the old family computer which I did not build, so I'm not sure exactly what it is).

I'll be running Ubuntu on the rig, and I usually use MSI Afterburner but it doesn't seem to be compatible, what is a compatible program which supports overvoltage?

Also, and this applies to CPU as well, which monitoring programs are compatible with Ubuntu? I usually use HWMonitor and CoreTemp for CPU temp, and Afterburner and HWMonitor for GPU temp.

Thanks in advance,
LAF

For your GPU clocking question, research NiBiTor. That will allow you to modify the GPU's firmware for clocks and voltages, but you will have to use a Windows pc to set it up the first time. I'm sorry I don't have any input for your other questions, but it's a start.

So you're saying, overclock it using my main rig, and then just put it in the other rig?

You'll have to for that route. Find the card's stable clocks and voltage on a Windows pc, then flash a NiBiTor modded BIOS to the card using NVflash booted from a removable device. That will set your card to your clock settings of choice and keep it there. You can revert to the original BIOS (or an updated file from MSI, in other words an official build) if you wish. The caveat is if you melt your card and cannot re-flash the bios to an official version you may get dinged on a warranty replacement.

Sorry about the Win-centric response.

Coolbits can be used to overclock older NVIDIA GPUs in linux, however it doens't work with the newest (400 or 500 series) GPUs. I have read that NVIDIA said overclocking is coming to the mewer GPUs in linux but that was months ago and haven't heard anything since. BIOS flashing is the only way to go.
