I just built a system today with the AMD Phenom II x4 965 Black CPU and the MSI 880GMA-E55 mobo. I flashed the BIOS with the latest working MOD version 25.2 with the MSI SLIC2.1. (It was in the MOD section here in the forum) I just noticed that Windows only sees 2 of the 4 cores in teh performance meter. However in the BIOS, it's showing me 4 cores. Can anyone enlighten me? Is the BIOS mod that I flashed bad? Or is there something wrong with my install? I havent noticed any problems other than this CPU core issue. I probably would not have noticed it, but when I tweak the systems I build, I always go into the advanced options of MSCONFIG and check mark the number of processors. In this case only 2 is available with began me down this road. I've already gone through all the BIOS menues making sure there wasnt some sort of setting to reduce/disable/ core features but nothing like this stood out @ me.
