here is a mobo that supports 125w cpus and some ddr2 ram http://www.gigabyte.com/products/product-page.aspx?pid=...
however under specifications it says
"Support for DDR2 1200(O.C.) /1066/800 MHz memory modules"
im suppose im just a bit confused about wether even though it says "1200(O.C.) /1066/800 MHz", if i can put 533mhz in it as it might just be listing top speeds rather than all the speeds.
Look at the CPU support page. If your chip is a C2 version then it will work with the shipping BIOS version F1. If you have a C3 chip then you need to update that BIOS, or hope it ships with at least the F3 BIOS, or it won't POST.
