If that's your attitude, remind me never to have you build me a system.
"So there is no way I can run two stick of 667 on this board???"
I have no idea what you have or what you've done. The RAM *should* work together in dual channel mode provided the specs are the same & the BIOS is configured correctly.
For another $10-20 you could have gotten a modern AMD 780G board with 4GB of DDR2-800, but to save a few bucks you got a board based on an old chipset & only 2GB of DDR2-667 which apparently doesn't work properly.
You got what you paid for....
