Higher PCI-E bus frequency = Higher OC?

[Nightsilencer]

Hey guys;

Currently I have my Asus 8800GT @ Core: 700mhz; Shader: 1705mhz; Mem: 1030mhz(2060mhz effective). You all know 8800gt stock speeds, and I cant say it's a bad OC at all. This brings my 3dmark 06 score up from 11k to 13k(almost 14k actually). That's breaking into 9800GTX+ territory right there.

This is as far as the card will go while being stable, apparently. At least @ stock voltages. I don't really know how to increase my GPU voltage, and I don't think I have the know-how to do it without breaking it 😛 Is there an "easy" way to do it?


Apart from that, I would like to know something. Would increasing the PCI-e bus in the BIOS help with a higher OC?

I keep the PCI-e bus @ the normal 100mhz, but would pushing it to 105 or so help in any way?

Basic PC specs:

Asus P5Q Pro

E8400 @ stock (no need to OC yet)

ASUS 8800GT Glaciator

4GB RAM DDR2 800mhz - Transcend

I doubt it, the ceiling on your chip is most likely reached as your chip is already running at whatever frequency you already set it to. Changing the speed at which your card communicates with the rest of the system really has nothing to do with the overclock as your card is most likely not starved for bandwidth.

You're really chasing a red herring.

Some nVidia cards overclock themselves when the PCIe speed is increased.

higher PCIe speed = greater probability of dead card

should just keep the PCIe speed at 100 MHz and OC the GPU / VRAM speed

I believe some 9600 GT did that because they used the PCIe bus as the clock generator.

Ran a PCI-e bus @125 made a difference in 3dmark in sli for a year.
When the first 8800gt came out blew 1 card at 145 PCI-e bus .
Only ran 8 3d marks before card died.
Reset to 100 when new card came in + i keep mem below 975 core 745 water.

Supposedly GTA4 shows an improvement but other games I doubt it helps.

hrmm... sounds interesting... but i'm poor so i'll not try that can someone test this theory ? post results... ?
