Here's a bit of information: I can change the bus speed and that pushes up the frequency to 1650 or whatever it happens to work out, It almost seems like the multiplier locked itself at 16
I will run a benchmark when I get home tonight (at work right now) and post scores, but I'm not so hopeful. I mean I'm running Prime95 on stock cooler and the temp only goes up to 50C, what does that tell you?
Have you tried using the tuning program from ASUS?
While you mention this, I effectively had this problem. The motherboard was sitting at x16 after I changed via gigabyte's tuning program the vcore. Previously, it was doing x42 multi fine.
Try to disable Intel speedstep and see what happen. Change the performance profile in windows, put it on extreme too. I personally think it could be windows related problem but if disabling speedstep does not make it, you got a defective mobo. Also, try changing the multi via ASUS's tuning program!
