Well there's obviously a lot of interest in these so I'll try and keep this post updated as to progress. Installed last night on a DS3 with 2gb of Corsair PC5300 and a 1900xt. Haven't had much chance to play with it yet but it's sitting nicely at 2.62Ghz (7 x 375) at the moment, done a couple of quick 3dmarks and some stability tests and it's rock solid. No extra volts added yet. Cooling is a Zalman aero flower, the Gigabyte hardware monitor reads 37c under load but I have no idea how accurate that is.
