HP d530 SFF(DC578AV) RAM COMPATIBILITY ISSUE... PLEASE HELP! WILL SEND BEER TOKENS.

I'm having a nightmare with my HP d530 SFF(DC578AV) Intel(R) Celeron(R), 1995MHz. 248 mb.

The mother board contains 4 RAM slots. Two of which contain a samsung 128mb PC2700 DDR CL2.5 stick of RAM.

I wanted to upgrade the memory on my PC so I bought two kingston 128mb PC2700 CL2.5 sticks of RAM. I seated the sticks into the spare slots, powered on my PC and it automatically (as it does) discovered the additional memory but only said that there was now 504mb of RAM rather than the expected 512mb. I accepted the change but upon boot up the graphics were completely distorted and I'm sure there was a message reporting a windows error (from what I could make out). I removed the two new DIMM's and my PC works fine as it was! The samsung and kingston DIMMS looking COMPLETELY identical (I know that doesn't mean much when it comes to RAM).

Anyone have any ideas!?!?! They'd be much appreciated.

Very kind regards,

Matt
