I have been trying for two days to unlock my other two cores on my X2 BE. I followed the guides I read about switching to hybrid and such. I ran CPU-Z and it said I had a X4 but at the bottom it showed I only had two cores going. So next I tried msconfig, boot, advanced and I could only select one or two cores. I read that maybe you need to up the voltage and I tried that in AMD overdrive but every time I changed the voltages and restarted the cpu voltage and nb voltage went back to what the default was like I never changed them. Any help would be GREATLY appreciated.
