Don't give up yet. And for the record, I'd say bluescreen is better than having your pc freeze.
This board has lots of "fsb holes". It might not work well at say 1500 but will work at 1550 to 1620 then fail till around 1700 again. It also depends a lot on the cooling on how high you can push your board. Plus different boards and different cpus are not all made equal, so it's trial and error to find out what your board and cpu can take.
I personally have one of the best air coolers on my cpu with two 120mm fans hooked up to it at 2000rpm. Plus I have four 80mm fans blowing air direct onto the board (plus the usual case fans) and I leave the side of my case open. The better your cooling, the more stable your board will be.
Start at 2.66Ghz on your cpu and increase your fsb by say 40 or 50Mhz a time from 1333Mhz (default). If you run into a troublesome fsb area, push past up to a couple hundred more Mhz to see if you just hit a fsb hole. Personally I find over 1840Mhz on my board is too much for it to handle. I've probably hit a fsb hole there, and the jump to get over it is just too much for my board to handle with just air cooling and the stock northbridge heatsink (which I believe is not copper although it's painted a copper colour).
For me, the areas I'm able to get my board stable is at 3.2Ghz and almost anywhere in the 3.4Ghz to 3.6Ghz range. Between 2.9Ghz to 3.1Ghz and 3.3Ghz and 3.4ghz areas I had lots of stability issues.
Also, the lower your able to keep your voltages on the HT, NB and cpu, the less heat you will generate and the more likely your board will be stable.
So really, it's a lot of trial and error till you get a feel for what your board can do with your cooling. First find a fsb where your board is stable, then lower the voltages as low as they can go while being stable, then try for some more fsb and up the voltages again if needed.
If your board totally locks up (as in, you cant even boot to the bios), just unplug the psu, take out the motherboard battery (supplies power to bios when pc is off) and switch the cmos reset jumper for 10 seconds, to revert back to stock settings and you should be good to go again. I only had to do this once on my board out of maybe a couple hundred attempts at changing the bios settings trying to refine my overclock.
Once you do manage to successfully find a stable overclock for your board, it's quite a euphoric moment of achievement.Edited by pmurgs - 1/5/10 at 10:20pm
