Yup, on the 8rda+ I could barely hit 2.6ghz with 1.75v - 1.80v vcore. Now it's rock solid at 2.8ghz using 2.0v. Bootable and totally usable at 2.9ghz 2.1v. At that speed, after a few prime95 tests the screen blanks out. The mobo I'm using now is straight out of one of my folding@home rigs so there is no extra cooling at all besides some AS3 on the NB. I'm going to try putting heatsinks on the voltage regulator and ramsinks like I did on my 8rda+.

This chip runs pretty sweet considering I only have a few hours of use on it so far. 2.9ghz stable seems really possible. Just not on an NF2 based board I'm afraid...

By the way the 15x multiplier is working by setting the bios to 7x.
