It is a CAB2E.
Well, I've been running it at 2100 for a while(2-3 months), playing BF2 so I figured it was pretty well burnt in by now. Decided to go up more this past weekend. I tried 2450 at other current settings and it locked in 3DMark05. Bumped it down to 2400 and everything was perfect. Played BF2 for 5 hours solid no problems. I need to bump the voltage on both cpu and mem and se what it can do.
