512MB - not, in Compaq Presario 7461

Added 512MB to this machine. BIOS counts up to 128MB then red COMPAQ logo
on screen goes awry and machine locks up. Any suggestions? Memory seems to
match Compaq specifications (although they're vage on their website!).

Crucial, oddly, doesn't list a 7461. It does list a 7462 and indicates that
max memory is 512MB (2x256). My guess is your machine will not work with a
512mb DIMM

Sorry, should have said its 2x256MB, as per the Compaq website
(http://www.hp.com/uk/support and search for Presario 7461).

It needs to be Single/Low density RAM. For a 256MB DIMM, it will have at
least 8 chips on each side of the DIMM. If you put a high density DIMM in,
only 128MB of it will be detected.

HH,

There are 8 chips on each side of the boards that I have. Should there be
more? Is there some other way to determine low/high density?
