ep45t-ds3r overclock won't latch memory

[rumblpak]

I'm running the f4c bios currently and I have a stable system right now. The issue is that I would like to be able to overclock as I'm running an H50 to my cpu it can go much faster. Only problem is, as soon as I take my computer anywhere out of spec it wont latch the memory and refuses to boot.

Any guesses?

ep45t-ds3r [f4c]
intel core 2 quad 9650
G.Skill F3-12800CL9-4GBNQ running at 1333 at 7-7-7-20

thanks,

Re: ep45t-ds3r overclock won't latch memory

Apparently it is an issue with the memory latch and memory voltage in the beta bios, reverting to the F3 bios allows me to overclock and change the memory voltage without a hard crash. Now to get to 4.0GHz stable...
