I've seen my X2 fluctuate when I start the second instance but only for ~ 5 seconds

Try leaving the 1st instance going for 30 sec before starting the 2nd

If your mount is even the tiniest amount uneven one core will not be cooled as well as the other = unstable
I understand what you are saying but cpu is 38C under load with a 30C ambient. I have 1/4 turned the top nut and checked temps while cpu is under load the adjusted the bottom nut give or take a quater turn at all times watching temps. Also did this in the bios as well. Temps are good under load.

Even tried adjusting nuts slightly while trying to run dual prime.....no matter what I do one core will always be 100% and the other will be jumping all over the place.....then it seems to switch over and the one core that was jumping up and down goes to 100% and the other that was at 100% starts to jump all over the place.

Faaaaaarked if I know what's the matter.

Wonder if it's my PSu no giving enough juice, 12V is sitting on 11.7V that's with 8 fans, pump, 2 x 512MB 7800GTX's, 4800 X2, 2 x 74gig raptors....you'd think the Silverstone 650W would handle it.

The system seems REAL slugish when I try to run dual prime. Things have micro freezes eg, opening explorer or web pages etc.

Bloody hell the comp ran better on air

650W Silverstone's 12v can be adjustabled externally just up the 12V rail while connected to a DMM
