I don't get it; what do you mean by pushing it. please explain in detail. thank you
Apologies, let me rephrase.
By push I mean increase the workload to as close to 100% as possible. You mentioned that you disabled Speedstep, but it might be useful to check what the CPU does under a high load. I believe there is a piece of software called prime95 that can be used to stress-test your CPU.
