Pretty average 2570 Mhz from 4800+

ABIT AN8 Ultra

AMD 4800+ @ 12 * 14 = 2570

Hi,

I'm begining to think I've missed a setting somewhere in the BIOS as I was hoping to reach 2600 Ghz at least.

All I've really set is the DRAM timings and the FSB. If I go over 214 on the FSB it dies in Windows.

Is there another setting that ensures the FSB only affects the CPU and not all the other devices OR something else I should try?

Any help appreciated......

Drop the HTT multiplier to 4x for up to 250 FSB, then again to 3x for anything above 250.

Mmm 2600ghz would sure be fast you means mhz?

You may need to up your cpu voltage up a bit. Push it up 5mhz or so at a time and test it for a while though!

Ive just bought this chip knowing that they aren't the best clockers but wanted to upgrade my 929 rig that may be all she will do, its a bit hit and miss with these chips. You will need to up your volts as Xez states and keep any eye on your temps.

939 surely?

See how far your motherboard and CPU can go before testing the ram. Put the ram on a low divider for now say 133 mhz.

If your are getting 2.5ghz on stock volts that aint to bad. Up your vcore a notch (1.375) and then increase fsb 5mhz, test for stability and then if its ok up the FSB again another 5mhz - keep going until it gets unstable then increase Vcore another notch (1.4) then go back to inreasing FSB. Keep going until you either reach 1.6 vcore or 60c LOAD temp as they are really the absolute limits on air cooling.
