Hello Everyone, After running the CPU-Z utility, I notice that my multiplier on my AMD Phenom X4 955 BE is jumping from 16, to 4, to 10.5. When I first boot my computer up and run CPU-Z, the multiplier is set at 16x, but after about a minute it drops to 4x. Every 20 seconds or so it jumps to 10.5x then back down to 4x then sometimes up to 16x (16 is factory default). I have reset my BIOS to default with no overclocking and even updated to the most recent BIOS version from Gigabyte. The motherboard I am using is a Gigabyte GA-MA770-UD3. I have disabled C1E in the BIOS as other posters mentioned. What else can I do to get the multiplier to stick. Thanks in advance for your help!
