Upgraded my P4T533-C to P4T533. I got it used, but I can't install a thing. Tried setting up the RAID, but when trying to install windows, I get BSOD'd. My WD HD had a bad sector, so I ditched the RAID, but I still get BSOD, reboots during/after windows installer, etc. I'm thinking there is something wrong with the RDRAM memory controller. The error message says something about IRQ_NOT_LESS_OR_EQUAL and also WRITING_TO_READ_ONLY_MEMORY. Any ideas? BIOS is 1006 beta. I'm going to flash 1006 release.
