C1 means detect memories
-auto-detection of DRam
-auto-detection of L2 cache(socket 7 or below)

P4 3.2GHZ
kingstom 1GB DDR 3200

Look at the motherboard manual. It looks like you have to install memory in even numbers. (2 or 4). Means you need to install either two or four memory sticks, can't run on just one.
