I'm was trying to tune up my now very old gaming rig. I have an FX8350 with crossfired 7970's. I don't play any newer stuff so it still does ok. I was using Speccy and it only reported 1 core and 1 thread. CPUID shows the same thing. AMD overdrive shows only one core. Windows 7 device manager does show the 8 cores. I went into BIOS and switched to manual control of the CPU and enabled all 8 cores. The utilities are still showing 1 core. Am I only using 1 core? And why is that happening? No wonder my gaming is sluggish.
