RAM Upgrade not working

First of all - sorry if this is in the wrong area, it coulld have gone into so many areas!!!

I have a ASRock P4i65GV Motherboard and have bought 2 1GB PC-3200 RAM.

However my motherboard will not recognise the RAM.

The sticks are brand new, but I id not clear the BIOS first. I updated the BIOS to the latest that I could find as I thought it was that.

I now have a feeling that the reason is that the Motherboard can handle the Memory but the processor can't.

According to CPUz:

Motherboard

The manual said -

So I guess I need a bigger processor - starting to get a little over my head now.

Any Suggestions?
