Asus BIOS help? - Overclock.net

BlankThis · 11-22-08

Well I've been trying to OC my processor and I'm rock stable at 3.325GHZ with 1.30v set in BIOS. That's 12.5 x 266. But once I try upping the FSB to 280 it's unstable unless i put about 1.38 (Which is outside the safe zone for the chip) so can I up the NB to help with stability and what else? I find Asus uses different terms then what I'm used to seeing here...

Handing out +REP like candy for those who deserve it

I have the same board, leave the nb and fsb termination on auto, set you strap to 333 and up you cpu volts 1.375v and cpu pll to 1.66v just try it

What's the "strap" and what will setting it to 333 do? And what does CPU PLL do? I see it but I didn't know what it is so I left it at stock.

To my understanding it has to do with OC'ing quad cores

Oh... Looking for dual core, 45nm help here

The FSB strap to NB is the clock Intel assigns to the NB. It has to do with the ratio between FSB speed and RAM speed. Some straps work better with some FSB than others. It really depends on your board. You might want to read this regarding straps. It's specifically a review of an x48 Asus board, but it explains the straps.

Here's a good explanation of CPU PLL.

i am using a 45nm dual core m8, if you look at system specs ours are very similar, cpu pllv will help general stability weather in dual or quads, quads need higher cpu pll than duals. strap is what he said, but on this board its a tad weird I would say that you are either using to little volts for the oc you want or your ram is being buggy, just remember when you set 1.3v in bios you actually are only using 1.28v real life so you have some play for the "safe zone". I run 1.45v + 24/7 on my E8500

I thought max safe volts for 45nm's was 1.3625v in BIOS.
