openSUSE Forums: Second CPU not recognized

openSUSE Forums openSUSE Forums

Second CPU not recognized Feb 14th 2013, 02:12 I've been searching for a while and clearly must have my terminology in a big mess when it comes to the whole CPU / Processor / Core thing but in any case. I am running a Dell precision T7600 box with 2 Intel Xeon chips, that's dual 8 core chips. For whatever reason I can't seem to get the other to show up. I've run the various commands that check if it sees the second chip. I booted on my windows partition, and that sees all 16 cores. I even thought I might have messed something up in the bios when I turned off hyperthreading but that seems to be of zero help. (32 cores show up when I am in windows but still no luck in linux with hyperthreading enabled). My BIOS shows 2 8 core processors, pretty much everywhere except linux.... I've tried a command along the lines of acpi=off. I am unfortunately tired and out of ideas of what it could possibly be. Does anyone have any recommendations for me? I am running opensuse 12.2
