My Spec:

-AMD 9950 2.6Ghz Quadcore Phenom Black Edition Processor
-Abit AX78 Motherboard
-ATI 1GB HD 4670 PCI-Express Gfx Card
-4GB DDR2 Kingston PC2 8500 1066Mhz RAM

AMD Overdrive recognises and allows tweaks to the CPU but the Motherboard and Gfx Card shows no information and cannot be tweaked.
