RAM upgrade fail

Specs: Windows XP v5.1.2600 SP3, Pentiun 4 3.2GHz

I just got a new 1GB memory stick to upgrade a desktop PC from 1GB to 2. The problem is, the new memory has not been recognised. The PC has 2 slots, one of which was initially empty, and the memory details are: 1GB DDR2 PC2-5300 667MHz (both old and new match these specs).

So far I have:
- Tried the old and new memory one at a time - both work fine, giving 1GB each.
-- (I've done this in both slots, so I know those are good too)
-- (I always ensure the memory clicks fully into place, as I know this can be a source of problems)
- Removed and replaced the motherboard battery to force it into a full refresh, then rebooted with both memory sticks installed.
-- (Advice elsewhere said this might force it to see the new memory, but it did not work)

So far I haven't:
- Upgraded the BIOS
-- Following the Phoenix website link suggests I have to pay for upgrades, so I'll try that option if people think it will help.

The boot-up text shows "DDR2 at Row(s): 1" when both are installed, which I interpret as meaning the BIOS itself can only see one of them. Is there anything in the BIOS settings which might help?

System details are below. Note that this is a relative's PC and I see them infrequently, so won't get to try out suggestions straight away, but will do my best to provide any extra info if needed.

Make & Model: E-System Ei-314
Windows XP Professional v5.1.2600 Service Pack 3 Build 2600
Processor - Pentium 4 ("x86 Family 15 Model 4 Stepping 10 GenuineIntel ~3199Mhz")
BIOS Type: Phoenix-Award
BIOS Date: September 5th 2006
BIOS Version: 6.00 PG
SMBIOS Version 2.2
Total Physical Memory 1,024MB
Total Virtual Memory 2.00GB (though I presume that doesn't mean it's worked after all...)
-(Control Panel shows 960Mb with Physical Address Extension)
-("mem" from Command Prompt shows:
-- 655360 bytes total conventional memory
-- 1048576 bytes total contiguous extended memory)

DO NOT update bios unless the errata says exactly this issue. And it doesn't I'd bet.So don't. Never pay for a bios update. Only the OEM board maker ought to provide and update.

I'd re-check bios settings for the ram. May have to lower it or set it slower.

I am not fully sure it is the ram at all. It could be the board too but the ram is still the prime suspect.

You do turn power off and remove AC plug and press power button a few times before you attempt this each time????

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
