Try lowering the MCH core voltage from the base setting of 1.10v to 1.05v.

I know this sounds counterintuitive, but it has worked perfectly for me and several others with this Gigabyte board and 2x2gb of RAM. It brought instant rock solid stability.

There are several posts on this.

You might also want to update to the latest bios version, which is F10. (But try to get the board stable first if you can.) I believe that the bios updates contain some small (and maybe not so small) bug fixes that are not documented with the releases.

Thank you for the reply. I will try Mch core voltage of 1.05v. Also, Can you point me to a good post about Mch clock skew? I am not sure what that is for.

Sorry, I'm not knowledgeable about the MCH clock skew.

Please let us know how the MCH core voltage reduction works.

Sorry it has taken me so long to reply, I was spending too much time oc'ing and needed a break. I ended up overclocking my e8400 to 3.8 and setting the ram to 1:1 which is 846. I also raised the performance level to 9 from 8 and now it is memtest stable overnight. Thank you for your help. I will probably need it again. :)

Oh I forgot to mention that my mch voltage is at 1.1 and that seems to be stable.
