trouble overclocking 2.0A

[DanTMWTMP]

First of all, how do you set the pci ratio thing?...people have been able to set the pci to regular speeds while the cpu goes higher....

well, aside from that, I'm trying to oc to 133 FSB. The max i can go is 111 FSB. Whenever I set the FSB to 133...the bios reverts the CPU back to 100 FSB upon bootup....this is very annoying and I bought the 2.0A soley for overclocking....u can see my system specs below.....oh and my ram timings are the least aggressive...i set it to 266 (i have samsung pc2700 ddr). ....any suggestions?

there should be somewhere in the bios an option to manually select pci/agp bus

also did you try to raise voltage?
those 2.0a werent all that good ocers, so probably a vcore of maybe 1.65-1.7 is needed

sometimes raising ddr voltage is needed too

heh, those were the first things i tried.....the voltage stays @ where I want it...it's just that the bios puts my cpu back down to default if i do any FSB higher than 111

Don't bother with the 2.0A's... i tried oc'ing mine and my friends too, *sighz* i can only get mine to 2.5(125fsb)stable with 1.75vcore... but i only run @ 2.3(115fsb) with 1.625vcore... memory @ 2-2-5 1T, =/ ... my friend's 2.0A won't even go 110 bus with 1.75 =X

well, the problem w/ mine is that the bios reverts it back to 2.0 upon reboot...i just want to get passed this hurdle.....after that, i'll find out if the chip is stable to overclock to 2.66

It's probably failing the overclock, so it reverts to the stock speeds so it can post. That's not a good sign for overclocking. The abit probably has to be able to post at stock voltages before the bios voltage you set kicks in. Therefore, if your cpu can't post at 2.xx at stock voltage, it will never get the chance to run at the voltage you set in the bios. You can always do the pin mod on the processor so the motherboard thinks the default voltage is higher.

yeah i saw the pin mod @ hardocp...but it's not garanteed that the chip will oc to 2.66...


well, neways, thanks guys for ur insight
