A few days ago I built a system with these specs:
Biostar t43d2-a7
e5200 with a VID of 1.15, CPU-Z says it was getting 1.12 originally
4GB Corsair DDR2 800
Corsair 400VX
I decided to try to do some overclocking with the stock cooler. I went up 10 mhz at a time in the bios, decreasing the RAM settings as needed to keep it under DDR2 800. I ran around 20 minutes of a Prime95 torture test at each step, the repeated.
I was surprised that I got all the way up to 3.375 Ghz (270 x 12.5) before Prime found an error. I went into the BIOS and raised the voltage +5%. The computer then refused to post. I tried a few different methods of clearing the CMOS with the jumper, and I got it to reset eventually.
Then I ran an Intel Burn Test at stock speeds just to see if it was working right. I left it alone to do the test, and a few minutes later I found that the computer would start up with the fans spinning etc. but wouldn't post. I tried resetting the CMOS with the jumpers in different ways (PSU off/on, pressing the power button when the jumper was on 2/3, etc). It still will not post. Note I never actually changed any settings after the first CMOS reset.
That's where I am now. I would be OK with the stock settings if I could just get it to post.
