Default PCI-e frequency too high ?

Popescu Madalin · Mar 3, 2014

Hello there.I have a question..Yesterday I've bought a motherboard named ASROCK 945GCM -s and the default PCI-e Frequency is 115.Any ideas ? I've heard that a value higher than 100 can screw up my HDD and my videocard.

I'm not sure where you heard that especially since your hard drive doesn't run off the PCI-e bus. but to change it you will have to go to the BIOS and there will be an option to change it. You should be fine though that's actually used fairly often to overclock GPU's

PCIe bus can be overclocked, but is very touchy, as it is what most secondary components talk across, including the SATA controllers, you may get away with raising it a few mhz to get a few extra FPS, but risk corrupting traffic.

Thanks for your answer,Spectre494.I forgot to tell you that : If I decrease the PCI - e frequency,my pc won't boot anymore...

Popescu Madalin :

In that case probably best to leave it there unless it causes problems. Your GPU or something must expect the 115 for some reason.
