I have 4x 2gb Dominator PC8500 ram moduls one par is rev 1.1 and the other is 1.2 if that makes a diffrence. I have tried alot of settings on the ram now with alot of diffrent timings but it dosent get stable at all. Do u have any tips?, I have read the dominator thread on extreme bandwith section and they have 8gb of ram stable on alot better timings then I have. What am I doing wrong? I will post bios settings that works for my 4gb setting:

That has worked for over 1 year 100% stable with 2x2gb modules, now what should I do to get 4x2gb stable? is it impossible?

Here is the memory thread btw the first postar has the same mobo as I have and only diffrent cpu and his memory runs fine on alot higher fsb and tighther timings:

and note I am still using bios 1307 is that my problem?
