I've got the + version. I used the supplied heatsinks on the voltage thingy chips and replaced the NB heatsink with an old Pentium 5x5 sink with a nice fan. Got my motherboard voltmodded too. I reached 2750Mhz with my Clawhammer with 1.85V though a little bit unstable,I had the LDT on 4x. I think you should try to get that stable too. For now its the psu thats holding me back , the voltages fluctuate way 2 much about 0.1V on both Cpu and Mem. But hey what else do you expect with a no-name 300W . System won't even boot with a Vcore of 1.9V . When I get a new psu I hope to break 2.8Ghz.

btw:
I've got an AMD 64 3200+ 1Mb Cache XPMW
