Soft over-clocking 8400GS?

post #1 of 7
Thread Starter 
Hello.

I recently picked up a cheap used PC for turning into a media box, and I was wondering what I could do with this accompanying graphics card.

It a variation of the Nvidia GeForce 8400GS.

My main hope is to be able to software overclock it, without a voltage increase.

Does anyone know how much I might be able to OC this, without drawing any more power than a stock PSU can provide? At least until I find a compatible power supply to upgrade the tower with...

MSI Afterburner or Riva Tuner - These are programs I would use.
HOWEVER, that graphics card uses a heatsink instead of a heatsink/fan setup. In that case, I would not recommend overclocking it at all.

Could I do a minor increase, without a fan? 10 to 15 % maybe?

I have an open motherboard port for powering a fan. Could that be used in a make-shift config, assuming I mounted it close enough to the heatsink? I know it wouldn't be controlled by the gfx card's cpu...

Just go for it, if it gets too hot, then stop. There is very little chance of "hurting" the card.

For higher resolution videos, it reduces framedrop, and this is using a minimal Linux with Mplayer.
