I could do 25 pass linx, run 200% memtest double instances and run 3 cycles prime95small. I changed CPU GTL Voltage Reference from 0.63x to 0.62x and set cpu skew @ 100. I dont know if its my idea but now all core temps are the same under load. Before these changes the core 0 was 2-4 degrees higher than core 2 and 3 and core 1 was always 1-3 degrees lower core 2 and 3 - under load.
