I think I made a mistake when running that benchmark. There must have been a background process running, as it is notably slower than when it was clocked at 3.2gHz. If I get access later I'll re-run it.
This is a partial result from before @ 3.2:

RDP to the rescue!

Re-purged, re-updated :smile:

Is there a final or recommended inventory list for the SB system?

Just an update from me, my 2133 ram now has unrecoverable read errors.

I did some more reading, and sandy bridge cpus are only rated for 1.5V ram. It can do 1.65V ram, but your technically over-volting the memory parts of the cpu.

This is what i'm running with atm:

1600MHz @1.5V I haven't found anything faster that is still at 1.5V.

I do notice the difference. In my pseudo-scientific testing I've found that faster ram does yield better performance for prime hunting (P-1 saw the biggest improvement). Sorry I don't have proper figures, but it takes so damn long to do tests properly :)

Also I found too the biggest improvement in stability came from increasing the "QPI/Vtt voltage" from 1.05 to 1.16V.
