Damn KTE! Thats some extensive testing :P :P Appreciate it

Now, the DLL which I am using is written by me from scratch since my search for a CPUID library failed miserably. It seems the real time CPU clock on the X4 is operating at the NB's frequency and not the core frequency. Interesting. (thats why the NB frequency is showing instead of the Core frequency, just a educated guess.)

Also slightly confused with your "x threads - y cores" results. For example, in the "2 threads - 1 core" screenshot, have you disabled 3 cores from the X4 and run the benchmark with the Core - 2 option? The 4 thread - 4 core result really intrigues me. Please post that screenshot (as mentioned below to help me debug this.)

I have updated my code to read the cache of AMD cpus now, care to give 0.9.7 a spin and please (if possible) take a screenshot of a 1E8 run (4 cores) + taskmanager (showing the 4 cores/utilization) + CPUz screenshot. You can use the "Screenshot" button on SuperPrime itself to easily save the screenshots
