overclocking nvidia card on linux

karnajh · 03-09-2011, 08:17 AM #1

hello,

No i have a GT 430 1gb, it's a small but good card <55 €

In windows i can overclock with nvidia soft, but in linux i can't find when i can make this, have you idée on this.

I have read, load the bios in windows, change the bios and re upload on the card, is a good way ?

Now on my linux64amd, with 4 virtual machines run, i have 50 FPS in mario double dash, is good..

Thk

You can use NVClock.

A word of advice though, OC'ing a card like 430gt wont bring any performance increases in dolphin. I'd go as far as saying zero improvement.

If anything consider overclocking the CPU instead.

Hello,

nvclock is for old nvidia, in windows if i overclock my gt 400 from 700 to 850 mhz, mario is more fastest, sure at this time i overclock my cpu 3.2 to 3.6 Ghz

Only play with nibitor and nvflash is possible but more complex and can have terrible issue...

You could also enable coolbits.

Log as root, go to /etc/X11/xorg.conf and under device add this patch.

Code:

Section "Device"

    Identifier  "Videocard0"

    Driver      "nvidia"

    VendorName  "Videocard vendor"

    BoardName   "nVidia Corporation Unknown device 0391"

    Option        "Coolbits" "1"

EndSection

Restart the machine and you can OC in nvidia settings.

I last used CB on Debian, fw 255.xx. Haven't tried since then though.

The riskier method is indeed modding the BIOS with nibitor like mentioned in that thread but if I were you, I'd just get a pre-made BIOS with the higher clocks unless you really know what you're doing.

You could also make multiple BIOS, one for standard clocks, one for OC etc. and just flash them as you deem it necessary for your current needs.

I had too much hassle with it though, using Windows 7 for gaming now & Linux for other stuff. Afterburner is so much simpler, & updated to work with newer cards all the time.
(Plus you don't have to use Wine for PC ports that aren't available on Linux).
