Is it safe to increase PCIE frequency?

Last response: in Overclocking

I got an AsRock 945GCMS mobo and the cpu fsb and pcie fsb are linked together :(  When set cpu fsp anything above than 224 the computer wont boot but when i increase the pcie frequency too above 100 then i can increase the cpu fsb even more, so is is safe to do so?
my cpu : Intel E5200 @ 2.8GHz (224*12.5)
gpu : XFX GTS 250 1GB
psu : Cooler Master 650W
mobo : AsRock 945GCMS

Highest PCIE frequency I have had success with was about 110MHz. Higher than that and my eSATA controller, LAN, and sound card go missing.

It is normally pretty safe, just remember that it can develop glitches quite quickly.

i just set the PCIE to 107 and cpu fsb to 240. Everything is going fine but hw do i know if its safe and stable now?


You can use Prime 95 to stress test your system. Blend tests test the whole system for stability and small fft tests just stress the CPU. I do not know what RAM you have but if you can run small fft tests fine and not blend tests then it is your RAM holding you back.

Just keep your RAM at or below rated speeds while overclocking the CPU.

I have the same motherboard as you before.

Yes, that motherboard will not allow you to overclock the CPU FSB much until you increase PCI-E speed as well.

If you do not use any additional card that uses the PCI interface as well as any SATA hard drives you should be fine.

how long does the test run, i ran the blend test for 3hrs and abt 10 tests were succesfull and more was going on. On top it said preparing workers. I closed it now since it taking long, so how long does it normally take to completed the test ?
