I went ahead and built a system using the Athlon II x4 620 and the Gigabyte M61PME-S2P motherboard. Basically it's working fine, but I have a question about memory speed. This motherboard has a AM2+ socket and uses DDR2 1066, however when I boot the computer the POST says the memory is running at 800 mhz. Does that sound correct? All settings in the CMOS are AUTO. I flashed the board with the latest BIOS and have the option to configure the memory settings manually, but I thought I'd ask before I mess with them. TIA for any help.
