Sorry for bring up the dead, but I have to post this info about my gf2 mx400. I was at yuandrew's house and he put the gf2 in his rig with a thermaltake crystal orb and as5 on the core. We were testing it and it got up to 240/280 stable and when we tried 240/290 and 240/285 it crashed and woulden't take it. For some reson in the pIII it would go up to 235/290 but the memory was cooled by 80mm fan that cooled the memory, and here that wasn't the case so that may explain why the memory woulden't go just as high, but I have to say I thank him letting me use his comp and do this testing. I still havent found a gf2 that oc'd as high as mine, and am still not sure if it's memory is sdr or ddr, but it still is a great little trooper that I got for $10.
