PCIE Bandwith and voltage in BIOS

post #1 of 11
Thread Starter 
I found in my bios an option that says PCIE bandwith and it shows -normal-fast-turbo- it was in normal, and i put it in turbo... and restarted... when I see in Atitool the card was overclocked from 450Core to 518Core and 685Mem to 730Mem and it run smoothly without artifacts and good temps...
Is recommended to leave it at turbo mode?

Other Question...
Also i want to push it a little more so i put 530Core and 740Mem but Ntune failed to pass the test.... what i have to do if i want to overclock it? I have to overvoltage PCIE +0.1 in bios?

If I put PCIE voltage at +0.1 in bios can i fry it?

Yes it can cause problems if you increase your PCI-E voltage, thats one you pretty much want to leave as is, it can cause various problems and its best to just leave at stock voltage. About it overclocking the card, I am not sure, I would say if it stays artifact free then it shouldnt be a problem.

Dont think 0.1 will fry the card. Run ati tool for 15+ min. If thers no artifacts you are good to goo with "Turbo" mode.

i think the stock settings for pci-e is 100mhz and 1.5v
and i dont think its a big deal overclocking your pci-e slots. just dont go nuts over it.

well the reson it is not recommended to change your PCI-E frequency, not the graphics card overclock but the slot frequency is because if you are using SATA hard drives it can corrupt data because somehow or another they are connected? Not sure how myself but try it and find out
