No, 5:6 isn't that bad. 1:1 is better, but not in any sense necessary. And I thoroughly agree that 3.6GHz on an e6600 is a bit on extreme on air, unless you've got some really premo air cooling happening.

What you might try, though, is reducing your multiplier to 8x, and try getting to 400 FSB at 3.2GHz. Up to you.

P.S. In my reply to your original post I meant to say you "may" have to up the NB voltage...the "may" was missing.

What's the advantage of changing my multiplier? A better ratio?

PS. Thanks for all the help. I've had a hard time finding info specific to my situation.

If you keep your current multiplier (9x), then at 400 FSB, your CPU would be running at 3.6 GHz. It might not be able to run at that frequency. However if you lower your multiplier to 8x and set your FSB at 400 MHz, this will allow you to run your CPU at 3.2 GHz and still achieve your 1:1 FSB:RAM divider.

what he said

and clock speed isn't the whole story when it comes to proc performance...say you've got two processors both at 3.6 GHz, one at 400 FSB x9 and the other at 600FSB x6...the second one is gonna smoke the first (all other things being equal, and both being stable). Not a particularly *likely* example, but true nonetheless

Sweet. I'll do that right now. Should I try a low voltage first? I'm thinking I don't need to go above 3.5v.

oops. Typo. I meant 1.35volts.

Also, my bios is locking up when I run at 400Mhz FSB. It would be 1600 Rated FSB to achieve the 400Mhz @ an 8x multiplier right?

[TriBeCa]

tell me you didn't actually mean 3.5

I'm now officially scared of overclocking ram, I took out 1GB of my ballistix, I was at 3-3-3-7-1T: 850Mhz: 2.35V, ram died, PC would not boot, first I was getting crashing in Bios, then no boot, tried resetting Cmos, did not help so I took one stick of ram out and the PC was fine, shame I aint gonna be able to play Bioshock when it comes out coz 1GB ram wont help and the damnd ram wont be here by then.

Has anybody else encountered problems where PcProbe II displays the Vcore incorrectly? (it's showing 2.14V while CPUz is showing 1.2V) I'm not getting any errors in orthos and my temps are good.

Dont trust any software to read voltages

Can you fill out your system specs so we know what you are running. Try 1.35v and +100mv, it should be enough to get you to post.

1600 is right, yeah. Did you work your way up to 400 MHz? And Asce is right...more like 1.45 than 1.35 at that speed. Also, if you're having stability problems, do try increasing the voltage to the NB.

By the way, did you reseat the NB heatshink on the board? The thermal pad that ASUS uses is total crap.

Before you RMA the RAM, make 100% it's the RAM and not the DIMM slot on the board. MY OCZ Platinum's killed two of the DIMMS on my first board.

Is that easy to do? I guess it would involve taking out the motherboard. I've mounted a 60mm fan on the heatsink and it didn't do much at all...which would indicate a problem with the thermal compound used. So it's just: Take out motherboard -> use pliers to remove heatsink -> benzine/alcohol to remove the thermal compound -> apply arctic silver -> reattach heatsink?
I dislike having a northbridge running hotter than my CPU
