Mav, what version of memtest did you use to burn in? For some reason my ram has gone upto 267fsb 100% but I havn't give it a single run with the burn in method, only been doing a sigle pass to find the 60 errors mark so I can burn them in but have just been increasing by 2mhz and am at 267fsb with no errors after 8 passes

. I also increased the voltage to 3.43.
These ram really are special. They even run Battlefield 2 with no stuttering just like a pair of crucial ballistix 2x1gb sticks I had.
Mav what is the theory behide putting the dimms in the freezer:? . How did you protect them against condensation?
