I know this isnt the exact type of question that should be in this forum, but i was hoping someone could help me anyway. My problem is: I dont know how to check what opteron I have. i have an IBM xSeries server 226, the processor is an Athlon Nocona 2.8 ghz L2 em64T x86 microprocessor. I'm wondering if it's Opteron Revision F's or later. or if it's revision E Opterons or earlier. Can anyone help in figuring this out?
