PCI E Voltage

post #1 of 5
Thread Starter 
Can you overclock your graphics card more if you add more voltage?

Sure can, thats why you also have Volt Mods for graphics cards... Generally PCI-E voltage is better for stability when running your processor at higher speeds though...

No, do not touch the PCI-E voltage. Only increase the PCI-E frequency (no further than 115 MHz if using SATA drives) to allow stability on higher OCs.......
Most boards don't even come with the option to add PCI-E voltage.....and they shouldn't.

Now if you add voltage to the GPU or video RAM then that's another story.....it will allow higher OCs in that manner.

PCI-E voltage will give extra stability when running high speeds on the CPU and GPU especially in a Dual-GPU configuration. When i was running my 3870's under DICE last night, i couldnt get my QX9650 stable past 5816mhz without some extra PCI-E voltage for 3d benching. For 2d benching PCI-E voltage does not need to be touched.

Well that's cool, I've never even owned a board with PCI-E voltage, and I've never heard of WR guys like Kinc or K|ngp|n messing with PCI-E voltage....but if it got you higher OCs then that's cool.
Are you sure that you're not thinking of PCI-E frequency or FSB Termination voltage or something?
