That's exactly what I have done..... ECS K7S5A and it is going great.
My P4-rig has it's motherboard back in Taiwan at present, so I have thrown my stick of DDR at it, and it is running really well.
Windows XP picked up all the necessary changes in the repair function, and it is as though I have my own PC back running again.
What a (temporary) relief!!
Great idea, and a great stable board...... not a single crash in sight. Temps stable around 30 degrees, so I'm a happy chappy.
