x800 OC Voltage Question

post #1 of 8
Thread Starter 
I've got a question about my AGP GPU, I was hoping to increase the voltage to this thing to help me reach a higher clock. I trolled the forums on this and read a little about hard-modding the board, which is fine, I don't have any problem with that cause I just sucessfully hard modded my MoBo. My question is, my MoBo allows me to alter the 'AGP VDDQ voltage' from 1.50 - 1.60 - 1.70 - 1.80v, will this setting increase the voltage to the GPU the same way a hard-mod would? Currently I've got it at 1.50v, what's a safe voltage range? These are by no means small increments, especially if you want to keep the temperatures as low as possible, any advice would be great

Wouldn't that setting be for the AGP bus's voltage? Not the actual GPU voltage...

I think that setting would only change with a higher end card which demands more voltage than your X800 is drawing... As far as I know, raising the mobo's AGP voltage won't raise your actual vid card voltage. I may be wrong though.

The short answer is no, I hope you found my guide easy to understand

You will have good results at 1.55-1.6 vgpu if you have a good air cooler, its probably around 1.3-1.4 right now

Upping the agp slot voltage can fry the card

Increasing the AGP bus speed makes for a very unstable environment. Just increse the clock on the chip with AtiTools or TrayTools

Hey Mister Crowley, I checked out your guide and noticed that it was for NON PRO cards, can I still use it as a general outline for the volt-mod?

If your pcb is printed the same way it will work, but it very well may not be. (look for the voltage regulator)

If you havent already, take a look at it, I thought you might have checked
