Ok bollocks.

Just opened the case up.

I have two x light purple slots, that my current memory is sat in. It doesnt say on the label on the stick what they are.

I then have 2 x blue slots that are empty.

The header on the motherboard says Dual DDR 400.

Also says Dimm1 Dimm 2 Dimm 3 Dimm 4.

So I assume they are all the same kind. Any ideas?

All 4 slots look identical bar the colour as well.
