I'm still not sure whether or not my memory is "fixed" - first boot this morning resulted in a long beep with C1 code which is a memory error, then my mobo went to safe mode (800mhz 5-5-5-15) so I had to manually set it to 950mhz 4-3-4-10 again. It's working fine now but I'm dubious about my most recent kit. Perhaps the freezer can make it better for a while, but if the previous owner had this kit at 2.5v for extended benching sessions, that's a bit of a death sentence. Still waiting to hear from him.
