I've got the DK and 9850. This is my very first rig to overclock.

In my overclocking I'm to the point where I just need to invest in water cooling. I'm able to get to 3.0 and pass a few minutes of prime95 blend but I hit 58C and get scared.

I think this is definitely overclockable even for a newb, I've just found that it has low ceilings with the FSB. With DDR2 about 236 and DDR2 1066 around 210 in my experience.

I don't know if some of you got lemons or what, but I love this gear.

I run the DK, 9850 and 2x2G OCZ Reaper HPC @ 1066.

Currently I'm at 14.5x200=2.9G passes prime blend for 15 min, will run longer tests soon.
