PCI-E Bus speed?

post #1 of 16
Thread Starter 
OK, I do know what it is but I want to understand overclocking it more. The Hz are set to 100 at the moment and I end up with a 2500 on the bus speed. So the multiplier has to be 25. But where does that come from? Is it locked?

So I can change the PCI-E's clock speed to double what it is now. Are there benefits from this? I mean my CPU to mobo speed is currently like 1500.

Please let me know what's up so I can help myself better. Thanks guys!

Leave it at 100MHz since it is independent. Do not change it or you risk data corruption.

Before you touch it let me tell you I have heard very bad things about frying things and corrupting HDDs with the PCIE Freq. But I know nothing about it.
Just a warning to learn truly what it is before you go testing

the pcie bus is not the same as your fsb. Pcie is kinda like pci bus its what goes to the slots like for your video card.

So, I'd burn up my 8800 GTS?? Dayum! It may not be the best but it wasn't cheap! Thanks for the info.

You are not really burning up anything. The issue is that the data passed around is corrupted since the frequency is too high. This would eventually corrupt your HD and you will have to reinstall OS. Besides, overclocking the PCIe bus yields no performance gain.

the only reason it can cause hard drive corruption is because the PCIE bus speed is linked with the southbridge.

the southbridge has as built in SATA controller, thus if you up the PCIE bus speed your also upping the SATA contoller/ USB controller speed etc etc

Yeah like I said, corrupt Hard drive
I wasn't sure about the frying components thing, I heard someone talk about frying a GPU, but there was no merit to it.
You guys explained better Corrupt hard drives and no performance gain FTL...

Hmmm... That would explain why there are higher numbers for the Southbridge to PCI-E than Northbridge to PCI-E under voltage controls.
