Well I picked up a Q9550 the other day, and noticed very inconsistent temps. At only 1.288v, coretemp reports core 0 at 80c, 1 at 75c, 2 and 3 at 70c at 100% load. This ratio starts at ~60c. So according to the Realtemp documentation, I should set the TJmax to 90c for the first core, 95c for the second, and leave 100c for the rest?

I mean, 80c load with only 1.288v can't be right, running a Big Typhoon on it, both CPU and HSF are lapped. Ambient is 68F (20c)

Nope, you don't need calibration you need a better cooling solution or check your mount for BigTyphoon.
You can do whatever calibration you want but distance to TJMax will be the same and when it will be 2 your CPU will start to throttle. Despite you fancy calibration. :)

Hmm, really? Well it's not like i'm unstable at those temps, but I always thought the BT would be enough. I've mounted and remounted, no change. Will a Ultra120 be better?

Sensors are correct. Bios is 2102, and it has had the same temps in my Maximus Formula, P5Q Pro Turbo, and my P5Q Deluxe.

The thing that bothers me is the clear disparity between the cores - core 0 is always 10c hotter than 2 & 3, and core 1 is always 5c hotter than 2 & 3.

I don't think Intel bothers to set TJMax consistently across all 4 cores of a 45nm Core 2 Quad so I wouldn't worry too much about reported temperature differences between cores.

Core 0 tends to be the most accurate on most CPUs and 80C is on the hot side for one of these CPUs to run at when overclocking. If you are stable then you don't have to worry about anything but if you're not then it's time to invest in a better cooler or try installing it a few different times to see if these temperatures improve.
