I replaced my 9850BE with a 9950BE. The 9850 was stable at 3.0Ghz@1.32V but it could not boot up over 3.2GHz. Strange but the 9950 needs 1.36V for prime stable operation at 3.0GHz but it able to boot up even at 3.4GHz@1.5V.

I got this CPU inside the box:



The CPU is exactly the same (except the last 3 digits in the SN) with that 9950 which appeared in the first Greek 9950 review. They were able to get 3535Mhz@1.475V in a MSI K9A2 Platinum(!!). After that I found a Japanese guy who has also the same CPU (except the last 3 digits) and he was able to get 3503MHz@1.45 in an ASUS M3A32-MVP Deluxe and PI stable 3209MHz@1.30V.

I have to say that something really wrong with the DFI LP UT 790FX-M2R + 9950BE pair. I use the latest 612 beta BIOS but I've already tried the latest final as well.

I can't wait for the SB750 boards... I'm going to throw out this board through the window. It has given me much headache since december...
