As the title says for loads under 4 threads the CPU is not stable. I've been having highly random crashes for months now with this CPU and after going through different motherboards and RAM I've come to the conclusion after testing with memtest and prime95 that the CPU is not working as it should. The CPU has never been overclocked or overvolted previously.
My testing with prime95 shows that whenever I set the thread count to lower than 4 prime95 finds errors within minutes and once I turned off boost (CPU runs at base clock of 3.6GHz) the CPU runs prime95 fine with no errors. Since discovering this I've tried overvolting with an offset thinking maybe the CPU is not getting enough voltage but I'm still getting errors. I'm not sure why this CPU is not stable at boost and was wondering if anybody has seen this before? This CPU was bought at launch so maybe I got a bad chip.
