Modded ASUS P5Q/Pro/Deluxe/Premium BIOS

[SPiTFiREgr]

Yep thats the same OCZ kit as I have. I wasn't looking for memory that clocked really well, just something that was fast stock and maybe had enough wiggle room to go to ~1150MHz. After 5 RAM kits I'm convinced the memory I have can't all be crap clockers, and theres another limiting factor somewhere.

Do you mean that you have tested OCZ kits with the P5Q PRO and there is a limiting factor somewhere else but the sticks themselves? When you say 5 ram kits you mean five OCZ2N1066SR1G kits?

I'm currently running those OCZ2N1066SR1G at 1154Mhz with 360FSB (5:8 ratio) and they are stable. But as i said raising the fsb (and as a result, memory write bandwidth) there is instability with blend stress (large fft).. Do you mean the same?

If high memory write bandwidth is the cause of the instability with certain memory modules then the only thing i can think of as the cause of the problem is inappropriate timing settings set by the motherboard (because there are some timing options that cant be set by the bios. even with manual selected ofcourse).
