CPU won't overclock from bios

post #1 of 9
Thread Starter 
If I exceed 349 MHz FSB from the bios my computer won't even post after a restart; I have to reset the bios manually to be able to do anything. However, I can exceed 349 MHz if I use a software overclock program from the desktop. I currently have the CPU core voltage set to 1.3V (which comes to 1.28V actual) and the NB voltage set to "Middle". Can anyone help me with this problem?

try to not use a crap Asrock board for starters. Except for the really high end asrock boards, most of them suck for overclocking. Gigabyte or Asus is the way to go if you wanna do some major overclocking.

try setting your northbridge voltage to high and see what happens. And check for a bios update.

I don't really have much choice about which motheboard I ue ATM.

Nice idea about but it didn't work . And I already have the most recent bios version.

Do I need to worry about any of these things: DRAM voltage, SB voltage, VTT voltage, GLTREF voltage? At the moment they are all set to "Auto".

Well if your overclocking your FSb you are overclocking your RAM.
try lowering the RAM:FSB divider by one notch. Always try to keep your ram at rated speeds unti you have your CPU completely stable.

Errr.... I am ashamed to say I don't know what that means . My FSB is currently at 348 MHz an according to CPU-ID the DRAM frequency is 348.4 MHz. Is that what you mean? Should I increase the DRAM frequency in the bios?

Well the DRAM is running below rated speed, so that isnt the cause.
Up the CPU voltage to 1.35v.

Is there much of a difference between overclocking using the bios and using software? I'm only asking because it looks like using bios is out for the moment

I have had this problem before with Intel Extreme Tuning utility. I had to uninstall it. Also try taking out all your RAM and powering your system on waiting for it to (beep) or reset. Put the RAM back in and try to overclock.
