Sent the SOC back to overclockers and ordered an Gigabyte GeForce GTX 480 SE instead. Installed the SE and it is better in every way. Even clocked at 820Mhz it is more stable, runs on less voltage and runs 15 - 20 degrees cooler while gaming. Very happy with it. Recommend the SE over the SOC to anyone mulling it over.
lol perhapswhen I joked that they'd binned the cores the wrong way round (SE/SOC) perhaps it wasn't a joke lol ?
otherwise there shouldn't be any difference
as far as I am aware other than the slight revisionon the PCB number (probably removes the dual bios switch etc) - they're the same cooler etc etc - 15-20C cooler is a massive amount!!
whats your current load temps then ?
mine even at 760 - gets to 95C after 15 mins of Furmark - but in general gaming stays below 81C
