It is a strange problem... I'm not very worried though, my performance seems fine even after starting many virtual machines and using all my memory.

I started a discussion for this issue here:

man i quit on trying HT ON, i settled to run it HT OFF.
i was really getting mad cause it was working before and now its no go..


i dont like the fact that when you load it with lots of ram, it does not reach the same full temp as a >9gb problem load.
ex. when you load a 5Gb problem size it reaches 83C on hottest core, and when you load <9GB it lingers 10C lower than then 5gb problem size test.

AIDA is a Single Threaded Bench Test, i used i7TurboGT to monitor the
multi's and the core/thread when troubleshooting.
