The vdroop is probably hurting the overclock. Try a bit more vcore, but then again, you're already right at 70C. Maybe try a cooler reseat as well? that's really hot for that voltage and clock speed.
Unstable Quad core Q6600?

is this normal for prime? and my quad?

Ok, first of all use small FFTs to test CPU stability, and second, yeah some variation is normal, but that looks a bit extreme for 10 mins into the test. Also looks like something needs lapped. 8C difference in the core temps.

Make sure you're runnings SMALL FFTs for CPU stability testing. Who recommended that cooler? I would have gotten a Xig over that.

Well, you do have a B3, but still, i doubt that chip is an inferno like mine. You use the correct amount of thermal grease?

That's not the correct way. Just put a rice sized dot on the middle of the CPU and let the cooler spread it.

OK:
1) You have a B3, they run hot
2) Still, that seems really hot for that vcore
3) You did not install the TIM properly. You need to apply as one thin line (preferbaly across the dies) Should be roughly the size of an uncooked grain of rice. Let the heatsink spread it out for you. if you did it with your finger, you most likely used too much. (which can also increase temps)
4) You will need more vcore than that to stabilize. However, your temps are getting high as it is, so deal with that first.
5) that cooler does not seem to be that great. I would clean all the old TIM, reapply and see how it goes.
edit:
6) Look up a pencil mod for that mobo. It will help stabilize the vcore and eliminate most of the vdroop. I had the same mobo and loved it.
7) Check with the manufacturer and make sure that you are running the RAM at the right voltage. Default on that mobo is 1.8v (so you are running 1.9v) which is fine, however, some RAM calls for 2.0-2.2.
8) Run memtest just to rule out the RAM. When testing the CPU, run as small FTT's to test just the CPU.
9) Listen to ljason8eg. He is on the right track

The temp and testing variations are normal. I have seen some cores off by 12C. I was testing mine last night and I had 7C-8C difference between the 2 dies.
