Overclocking Issues. Q6600

I have a Gigabyte EP45-UD3P and I'm trying to overclock Q6600 to 3.00GHz. I set the Bus speed at 333 with a multiplier of 9x, now the problem is, when I open CPU-Z the multiplier says 6x (2GHz) and will jump up every other minute for about 2 seconds to a 9x multiplier. Is it CPU-Z that is making this mistake or is my set up wrong?

Prime95, bout to go check out the other.

Prime95 stress tested for 3 minutes 0 errors 0 warnings.

You should stress with prime95 for a few hours, atleast. There isn't a set time really, but I've actually gotten prime errors after 12 hours of stressing. Check out this guide for any help.

I'm on stock cooling for now, when I get a nice heatsink and fan I will definately be pushing it.configme

Stock cooler. Check your temps when running prim95. I bet they are well over 65C on the cores. I would't overclock until you get some proper cooling.

No he shouldn't. I did some tests with stock cooler and the cores hit 90C after a few minutes at 3Ghz

Max temp I hit after crysis for 5 hours was 75c after which it goes down to 40-50c. .configme

That's too hot. Crysis doesn't even stress the Q6600 out like prime95 would. It's possible go to 90C with prime95 mine did for the few minutes I tryed.Cores over 65C is not so good I believe. As above says reduces you clock until you get a good cooler for overclocking.
