would it work effectively to have 1gb and 2gb ddr2 667 ram together using asrock wolfdale fsb1333 ddr2667 motherboard dual core cpu.thanks
DDR2-667 is the correct RAM to run with a 1333MHz FSB CPU. However, if you pair up 1GB + 2GB, the board will probably run the RAM in single channel mode. Regardless, it's still better than either 1GB or 2GB.
