Writing a CPU heater

I was talking to pm and he said he thought I probably wouldn't be able to write one... he's right of course. All my attempts result in lower CPU temps than prime 95 ;).

Anyway, maybe some people have input as to what I'm doing wrong.
I'm trying to do an FPU & ALU operation every iteration, an L2 access every ~24 iterations, and a main memory access every 75-150 cycles. I figure that should provide some nice heating. everything would actually probably be about half that, since each "iteration" would probably be longer than 1 clock cycle... especially if you test for validity of results

Two problems with actually implementing that:
1. to actually produce useful results, you need to TEST everything to make sure it comes out right. how do you do that without reducing heating? (since I assume that the processor can make "mistakes" before completely locking)
2. I dont know how to force an L2 or main memory access without creating huge arrays and jumping around. thoughts?
