PCIe Frequency Setting

[RaXoR]

Built my computer a few weeks ago and was setting up the BIOS. One thing I noted but did not change was the PCI Express frequency. It was set to 100 by default, but ranges from 100 to 200.

Motherboard: Newegg.com - EVGA 123-YW-E175-A1 LGA 775 NVIDIA nForce 750i SLI ATX Intel Motherboard - Intel Motherboards
Video Card: Newegg.com - EVGA 896-P3-1267-AR GeForce GTX 260 Core 216 Superclocked Edition 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

Can I / Should I change it up to 200?

No leave that alone. I don't know exactly what it does but everything I have heard says to just leave it alone. One guy on the EVGA forums said you can bump it up to 105 but it didn't seem to change anything when I did it so just leave it alone.

it's good for 3DMARK runs. Bump it 140-165 and you'll see an increase in score.

Oh really? Hmm I might have to try that sometime. I take it its not best to leave it up there or is it basically just another form of overclocking?

 

[thirdshiftdj]

No, I wouldn't leave it there for daily use and yes its another form of overclocking. Between 105 to 120 helps and is pretty safe. Running any higher I would only recommend when making a 3dmark run. Boosting the pci-e frequency helps w/ more bandwidth and texture loading. IE: gain some fps while gaming and higher scores in 3dmark.

edit: Like any OCing just be careful when doing it.

thats odd, i read all over that increasing the frequency messes with the SATA controllers and can corrupt data, and cause general instability if overclocked.... is that not true?

 

[thirdshiftdj]

oh thats true for sure. Thats why I say to be careful. Just like any ocing there are risks that you take.
