I had been running an E6400, 1.4v, 3.6Ghz, 1600FSB, works well.

Q6600, B3, get cheap, so I buy one till Penryn makes its debut.

This chip won't OC over 2.7Ghz, 1.24v 1200FSB. You may say, oh look, your voltage is to low, yes it is. There is a reason. If I set v to manual, the chip, or mobo (don't know which) begin to behave unusual. The bios sometimes reads a "current" multiplier of 24 at 8485Ghz??? It may boot through or maybe not. The vdroop is pretty high especially over 1.5v. It seems any amount of voltage increase makes no difference for the chip going over 2.7Ghz.

I have flashed bios to latest A30(I believe), done a full clear Cmos with jumper and reset all values to default. At default the chip reports as being a 6x multiplier at 1.6Ghz Quad. I can set the CPU multiplier to 9x and FSB to 1066, then it boots at that speed fine.

I bought this from ZipZoomFly Monday 23rd and got it Thursday 26th. It was $295.00 plus shipping, $297.00.

Should I return it for exchange and put back in my old E6400 or is this typical of a Q6600????

TIA

Maybe you just got unlucky?

Sounds like something is strange with your motherboard though.

Maybe luck but I never had problems with the board even pushing the E6400 up to 3.73Ghz with FSB around 1666 and voltage up to 1.55v, or about the chips limit.

Monday I'll decide after playing with it some more over the weekend. If it doesn't get any better I think its going back. I know its not a heat issue because it runs as cool as the E6400 did at similar speeds.

I've noticed that you are using the eVGA 680i SLI. What version of the board do you have? The NF68-AR have issue with overclocking the Quads. You should RMA it for the A1 version.

Never mind guys, I found out that my board is revision AR which has problems with going over 1200FSB with quadcores and Evga will be giving me an RMA cross ship for a replacement to fix the problem.

So if you to have an AR series 680i SLI mainboard and a newly acquired Quad and plan to OC, you will have to swap it out also.

Thanks to all that answered, the tech at Evga new exactly what the deal was, seems now that Q6600 are cheap, they are getting a lot of the same deal.
