Correct. My super Pi results was 15s which is around the right score for 3.6GHz on my system

No, i'm running unlinked at 800Mhz 4-4-4-12 @ 2T, same as I was before. I do suspect it's the NForce board, but I'm not going to read too much into it as bal3 said. It's a good test for stability, but the GFLOPS scores can be way off.

Yeah, this is why I'm not too worried Desert Rat. I ran 50 passes and I averaged about 30 GFLOPS, give or take a few (at 3.6GHz)

Make sure to disable Antivirus. And you can try and do what I did, start msconfig, disable all services and startup programs, reboot and try IBT again. It gave me a few extra Gigaflops. Using AVG totally kills my Gigaflops.
When running my Q9650 at 3.825GHz I'm in the 52 - 53 Gigaflops range.. if I remember correctly. So a Q6600 at 3.6GHz should be much higher than below 30 Gigaflops.
I'm currently running Microsoft Security Essentials, so you think I should disable that eh? And I believe you're right. I should be hitting around 40+ GFLOPS.

That's what I'm thinking. Not sure though. Could be. I've run it countless times and I'm either at 30, or below in GFLOPS

If you look at Desert Rat's Gigaflops results on the last page you see that he too has low Gigaflops results. He is using a EVGA 780i board. Something up with those Nvidia boards... No doubt...
Seems to be the case.

Let me reinstall chipset drivers. IBT should be fine.

Also, when raising vcore to those levels the motherboards voltage circuitry is being loaded very hard. And cheap motherboards with only 3 or 4 phase power circuitry can burn with too high vcores.. Also important that motherboards have 8-pin power feeding from PSU when overclocking Quad to the limits.
For Dual core overclocking 3 or 4 phase power should be fine. And with only one 4-pin powerconnector.
I would not have gone much past 1.45v vcore with a 'cheap' motherboard and a Quad Core CPU
You think the 780i is a cheap motherboard? It runs 8 phase power and just for you, 1.55v is the max you should go on a Q6600. I'm also on watercooling.

Could be something else, but eh.
I can pass 63 passes, so far on 3.6GHz at 1.45v I'd say it's stable. I could run 100 but it's not the point. Nothing but folding will stress my computer that hard.

(on edit, are SuperPi times scaling with the poor GFLOPS readings?)
SuperPi scaling is just about right for my rig at 3.6GHz (15s @ 1M)

I'd trust IBT/LinX before I ever trusted Prime95
Just as a side note: I was getting awful 3DMark11 and Vantage scores. Turns out it was the latest WHQL drivers that were causing such low scores.
I rolled back to 260.99 drivers and I got my scores back (the one's in my sig). So I'm not so concerned about this GFLOPS business.
