all help is appreciated

Switch the card thats on the mobo to "Dual VideoCards".

You'll probably only see a 1~3% performance los.

OK, I am researching my first attempt at OCing. I am not looking to 'max out' just to tweak for performance improvements that are know stable and up to around 3.0. This is primarily a gaming system, minimal photo/video processing.

First question is: to use BOIS, or the nVidia control panel. I guess there are opinions on this from what I have read. My gut tells me BOIS, but I'm a noob lol

Second, it seems my hardware is similar to many, does anyone have a 'canned' setup that they can share?

I assume my system will show up here.

additional info:

still running the origional BOIS version 0608 from 6/11/07

ASUS has version 1301 available, should I update first?

[Zippit]

update to 0801 (or was is 0803? :P)


Basically you first need to find your minimal voltage for your CPU. Do this by lowering your CPU voltage until its unstable. You can test this with OCCT, Prime95 or IntelBurnTest.

Next thing is raising your FSB. Its Quad pumped so if you set your FSB to 1600 you can calculate your CPU speed like so: (1600\4)x9 = 3600Mhz or 3,6Ghz. 1600 is the FSB, 4 is quad pumped and 9x is the default multiplier.

To come to that point of a 3Ghz OC you need to increase your FSB with increments of 25. Next check stability and monitor the temps with a program like RealTemp, Speedfan or Everest. If stable increase the FSB with another 25 until it gets unstable. You then increase your voltage 2 increments. Test and move on until you either hit an FSB wall, Temps get to high or your temps go sky high.

I hope I helped.

Could someone help me enter my memory timings?

I have this RAM.

I know the timings but how do I enter them? Like in the same order that I read them but then from top to bottom or something?

Has anyone else gotten the driver_irql_not_less_or_equal BSOD and found a fix...I get this practically every day, when trying to multi task on my system...I've googled this extensively and found nothing that helps....not sure if it's related to the board (can't have more than one sata drive hooked up without delayed write errors...or if it's related to the gpu (pny geforce 8800gt). I'm not overclocking anything and my ram timings are set properly. Can any one help?

I'd try re-installing drivers, and then a clean Windows re-install. Have you had this problem since you put this system together, or did it show up afterward?

Yep, set the bios top to bottom as you read them left to right.

Okey done that.


But I cant seem to get past 3.6GHZ I tried 3.69Ghz but even with 1.35v i cant get it stable! While 3,6Ghz only needs 1,23v

Have you tried leaving the memory settings to auto while you push the FSB?
