Thanks for the tips. For the record, my setup is:
CPU: Phenom II X4 945 Deneb 3.0GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor
Motherboard: ASUS M4A79XTD EVO
RAM: 2x2GB of G-Skill DDR3 1600 Mhz
Graphics Card: Saphire Vapor-X Radeon 4870 1GB
I realized that I had not installed all of the utilities that came with the CD for my motherboard. One of them was an update utility. I used that and it updated the BIOS with a more recent version. I think that's what did the trick (From original 3.7 rating to 7.3 rating for the CPU). My RAM score increased as well.
Thanks to everyone who posted helpful comments
