Having problems with your Intel Core 2 Duo E8400 LGA775 3.00GHz 6MB Cache 1333MHz FSB Dual Core Processor (BX80570E8400A) ?

My E8400 CPU is only showing one core instead of two

\015 My CPU is only showing one core instead of two. I've had this system for a year and recently noticed that Task Manager was only showing one core. I used 3 other utilities to see if they showed one or two cores - all show only one:CPU-ZProcess Explorer v 11.33Ashampoo Core TunerI ran the Intel Processer Identifier utility and it reports two cores, but it doesn't give any process/load info so I assume it's just picking up the E8400 ID and reporting two cores.\015

Can you mix 1gb and 2gb dimms in the same machine (for a total of 6gb)? I added two 2gb 1066 DDR2 dimms (''OCZ'') to a PC that already had two 1066 DDR2 1gb dimms (''Kingston''). I moved the 1gb dimms to sockets 3&4 and put the two 2gb dimms in sockets 1&2. BIOS settings are on ''Auto'' for all memory (5-5-5-15). When I boot the system, BIOS only detects 4GB of total memory (as does Windows 7 64bit). The two 2gb dimms aren't even recognized (yes, they are seated properly). Can I not mix 1 and 2
