I'm sure I could get past that with kinda normal settings but for anything higher the CPU only seems happy with a 9x multi. The ram seems to have great bearing on things as well, You need to drop it to 667 and up the voltage. I have no idea of the SPD settings for your ram so manually set the big 4 that you have listed and manually set all the others to their slackest for starting off with. I could only get to 290 fsb with the OCZ but up to 312 stable with the Geil. Hmm where did my sig go, I suppose thats wot I get for ticking on the box and not reading it. I'm just on my way out so I'll fix it later.
