Starting with my system info, even though it's in my signature: Phenom X4 9650 @ 2.3GHz 4GB DDR2 800 Gigabyte GA-MA780G-UD3H Alright. I've got the FSB set to 240, and the multiplier to 11.5. As far as I know, this should be giving me a clock speed of ~2.7GHz [I've gotten this before, note]. But for some reason I'm only getting 2.3GHz. Here's speccy: Code: Cores 4 Threads 4 Name AMD Phenom X4 9650 Code Name Agena Package Socket AM2+ (940) Technology 65nm Specification AMD Phenom(tm) 9650 Quad-Core Processor Family F Extended Family 10 Model 2 Extended Model 2 Stepping 3 Revision DR-B3 Instructions MMX (+), 3DNow!

I have a feeling it's my issue. EditEdit: I'm going to keep playing with it, but I'm not really sure if anything will change, if I fix it before I get a reply here, I'll report back.
