Thanks for the review - useful information as I purchase my own Haswell system that I intend to overclock. A very minor quibble: prime95 is not a "synthetic" test. It is actually a real world application that happens to also work as a heat-generating stress test. FYI, there will be a new...

Run the second instance with the -A1 command line argument. Or copy prime95 to another folder and run the second copy there. Do not run two blend torture tests at the same time as it will consume more memory than you have. Run two in-place torture tests or select custom test and decrease...

Try custom with less memory OR try prime95 version 24.13

Prime95 has two sets of torture test data. One for machines faster than 1GHz and one for slower machines. I'll bet your C'n'Q setup is tricking prime95 into using the data for slow machines. If so, you'll see "Testing 400 iterations...." instead of "Testing (many thousand) iterations..."...
