Can't get past 2.5Ghz on C2D
First off I'd like to say that at this point I keep shooting until I hit something.
MSI P6N SLi Nforce 650i
Core 2 Duo @ 2.13Ghz E6400
2GB OCZ DDR2-800 PC6400 RAM
Anyway I'm using a Dual Core Center from MSI and the BIOS to adjust my voltage levels. I had my Vcore running at 1.5 - 1.6 and my Memory Voltage at 2.10. I managed to get all the way to 315Mhz x 8 running at around 2.5Ghz. Anything past that and the system locked up.
I know temperature isn't a problem, I have a Zalman pure-copper heatsink and my machine was at around 28c *idle* while running @ 2.5Ghz.
I'm seeing people clock past 3.0Ghz and I really have no idea what I'm doing wrong, only thing I can think of is the RAM timings but I dont have the slightest clue where to begin on that or what any of the dozen values mean, I do have it running @ 800Mhz Dual-Channel.
Any help/advice would be appreciated.
