Performance increase by upping the PCIe from 100Mhz to 109Mhz?

post #1 of 8
Thread Starter 
Performance increase by upping the PCIe from 100Mhz to 109Mhz? To me it seems like a no brainer that the higher the speed the better. But, I get the feeling that it is otherwise? Any thoughts?

Upping it gives you no real benefit and in most case's will caust instability and if its too high can damage your component in the bus.

i dont think it will have much, if any increase because the cards dont even use the maximum bandwidth of the slot to start with.... we still havent maxed out the capabilities of agp slots, which run at 66mhz...

If you are looking for little gains look for your manufacture's suggested BIOS settings. I know eVGA has them on their website. It will tell you a basic idea about what everything should be set at.

My MSI 6600GT has no benefits at all. I tested from 50 Mhz to 200 Mhz and got within 10 3DMark05 points each time.

Yea I too would not recomend it. It gives very little if any benfit at all towards performance and like Jori said, can cause lots of instability. This instability is only increased when you are overclocking the card too. I would just leave it stock.

Good luck

I haven't experienced any instability and I've got mine up to 115Mhz. The only reason I raised it was because I wouldn't get video with the FSB clocked higher than 218MHz. Once I adjusted the PCI-E bus, everything booted right up, so far as I can tell everything is stable.

As shown in this post it ran with OCCT and Prime95 for 6 hours without a hitch.
