Question 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.

I have:

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.
Thanks!

I've heard about this too but don't know how to do it.

Anyone wish to comment?

is the ram for overclocking or is it value ram?

Disable stuff you don't need, like themal throttling, etc. Then set the RAM timings to SPD and lower the FSB:RAM ratio to something like 3:2 or 5:4. Increase the Nortbridge/chipset voltage if possible on that board.

This is just to make sure it is not the RAM limiting the CPU/FSB. You can try to get the RAM running at a higher speed afterwards.

i'm not sure but i'm thinking that perhaps the 650i suffers the same FSB issues as it's big brother the 680i :/

It can't be worse than the X975 chipset, and I'm at 430 FSB.
