PCI-E Bus over clocking

post #1 of 7
Thread Starter 
Ive been reading a lot about increasing oc stability by raising the bus of the PCI-E to between 108-112.

Now i always though this was to be locked at 100mhz and never to change it. Will raising it damage it or will we get better performance and stability.

My card is a Leadtek 7800gt

Thoughts please?

I would agree with the lock. It can fry your card if incorrectly done. But if it offers stability with no risks applied. Then why not.

Have you tried google?

people raise it to either aid FSB overclocking or to help the core of there graphics card go further, there is a save operational range to stay in, goin past it can cause all sort of instabilitys and problems, with in the 108-112 stated above you will be fine.

I would leave well enough alone. Why take the chance of frying your card? I don't think it will make that much difference.

I have heard a few people claim this helps their overclocks or adds stability. However, when they go back to objectively test it... there is no difference. If you want, you can try it yourself. Just OC in 2MHz increaments, overclock, and then run graphics stability for a few hours.
Once again...

A small increase like that is very unlikely to have any detramental effects on the equipment with the exception of the early Raptor 36G HDD like I have which is very tempermental to any increase in the PCI/PCIe bus speed.
Upping the PCIe/PCI may or may not allow for higher OCs, the harmonics in electrical circuits comes into play and may ballance better with the boost in bus speed.
