Ei-Sysytems RAM Upgrade

Hi,
I have an old(ish) Ei-204 UK and am desperate to upgrade the RAM.
Should be a simple DDR2 upgrade but the (three) different types I've tried don't work - the unit won't boot once I've changed. All were approved (apparently) for this machine.
Returning the old RAM works fine.
I've tried every combination of the 2 x 1GB RAM (one at a time in both slots, both together in both slots, etc) but nothing seems to work.
I've even been back to PC World and they tried the RAM they sell - again no joy.
The motherboard looks like a pretty standard Foxconn unit - is there anything else you can think of?
Thanks,
Simeon

Full spec from label is :-
E-S Ei 204-UK
512 MB DDR2 memory
80 GB hard disk drive storage
DVD RW dual Format
Unichrome Pro 3D/2D Graphics and Video Integrated
Fast Ethernet 10/100 LAN
6 USB 2.0 Ports

If you look on the motherboard there should be a number

P4M800P7MB-RS2H

2 slots ddr2 or dimm

you cannot mix DDR2 and DIMM

The 1gb memory modules need to be low-density
I.E. chips on both sides.
The motherboard can only recognise 512mb on each side of the memory module

Check the BIOS for the correct memory speed and voltage settings

You could also try the free Crucial memory scanner from click here. It will scan your PC and then inform you as to what type of RAM is compatible and also the maximum you can use.

Guys,
Thanks for your help.
I've tried high and low density boards, but not the Crucial memory scanner. - I'll check tonight and get back to you.
Cheers,
Simeon

Here's what I bought originally (from aememory online) :-
Tech Specs (12-616)
General
Storage Capacity 1gb
Upgrade Type System specific Memory
Type DRAM
Technology DDR2
Form Factor DIMM
Memory Speed PC2-4200 (533MHz)
Data Integrity Check NON-ECC
RAM Features UNBUFFERED
Module Configuration 128x64
Supply Voltage 1.8V
But they didn't work...
They then replied as follows :-
This is indeed a chip density issue, the modules you require for this system need to be 16chip (yes those black oblongs are the chips on the modules).

The new parts didn't work either, so now I've sent both back...
Their system scan showed this :-

Thanks.
Found it but can't see anything there that helps me understand...
It does specify 'Single channel DDRII 533 / 400 x2 DIMMs' but I'm not sure what the 533/400 means, although I'm guessing it's the speed.
Anything here that indicates why the RAM I tried wouldn't work?
