Memory upgrade not accepted after restore

Compaq / PRESARIO 6000
March 27, 2010 at 10:13:38
Specs: Windows XP
Presario 6092EA - Having upgrade my RAM to 2GB a couple of years ago, I have just restored the computer to factory settings with the restore discs. Now it won't accept the new memory saying only accepts up to 512MB (although the old RAM which it does accept is 768). Checking with the Crucial site again it still says I can upgrade to 2GB. Is this something to do with the BIOS?
NB I have installed XP service packs / windows updates and HP drivers

"Now it won't accept the new memory"-I assume you mean that only 512MB is listed in Windows XP under system ?When you upgraded to 2 GB, did all 2 GB always show under Windows XP before you restored the computer to factory settings ? Also, does 2 GB show now in the BIOS ?

Thank you for your speedy response.
When starting up, the computer immediately says 220-
Unsupported Memory Module.... Memory modules larger than
512 MB are NOT SUPPORTED.... System halted- so I can't
get as far as the BIOS or starting up in Windows.

Although when I first did the full restore I had the new memory
in - it suddenly said this on a start up and I then found the old
memory and replaced it. The only thing I think I could have
done is to update software for the chipset and ROMPaq from
the HP site. Since then I have reinstalled the restore discs

With the old memory in and using F10 it says in the BIOS
that I have 768MB (which is correct). I can't see anywhere a
maximum capacity - the BIOS options seem more limited
than I have seen in examples - Headings are FILE.

On start up in Windows - windows XP also recognises

In the specifications data from HP it says
configurable memory 128, 256, 512 (2x256), 1GB (2 x 512)
maximum capacity 1 GB
Total DIMMS 2
Total DIMMS Open one if 128, 256 or 512 used

However when I run the Crucial check it still says I can install
2GB (2 x 1 GB).

This is all very strange when the computer ran fine with the
new memory in for a year. However I can't remember
checking what windows was seeing (sure I must have done
but can't swear to it!)

As a follow up - I have just remembered that I made a note of
settings before I did the system reset and I did note that
Windows XP could see 2 GB RAM.

Sounds to me like the crucial scan is wrong. You could check your motherboard's site to see if there is a bios upgrade. It should give you an explanation of what the new bios upgrade consists of.

Well crucial was right up to a week ago when I reinstalled!

How do i find out what make is my motherboard? On the HP
driver/software site it has NVidia Chipset Support and CPQ Flash
Utility ROM update (for 686Y4 ROM family)

HP site does not have any BIOS software mentioned.

Thanks for your time.
