So I'm trying to overclock my E6500 and I hear people can easily get it to 3.6GHz. Last night I tried OCing a bit and I got it up to 3.3GHz then became unstable. I tried again today, I had my CPU at about 24C - 25C when I started and eventually when I got up to 3.3GHz my temps were only ~35C. Each core was about 50C however. Using Prime95 to check stability, it seemed stable at 3.3GHZ, until I tried running 3DMark03. On the second CPU test (I think 5 or 6 tests in) it rebooted.
I'm using AsRock OC Tuner to OC for now, I was gonna set it in the BIOS once I found a stable speed. I might have been going too fast with my increases in FSB and not letting Prime95 run for as long as it should have, would that factor in on not getting it up to 3.6GHz?
And in case your RAM clock is set correctly, check the voltage being fed into the CPU, you might want to up it by a notch, but make sure to stay within your CPU's specifications. I think the max voltage for a E6500 is 1.5V.
Went googleing for E6500 overclocks and found this again. So I was OCing again and I had it up to 3.4GHz/310FSB, then during a torture test it crashed with a BSoD ending in 124, apparently needs more VTT. So I uped the VTT from 1.2 to 1.37 and ran into the same problem, BSoD. Except this time it was another error ending in 3b. I can't find any info on the 3b error code, except some guy on Overclock.net suggesting it's RAM.
