Ok, so two lighting fast responses later...

The essential details are ECC DIMMS. The system has a 144 bit memory path
with 128 bits data and 16 ECC. DIMMs must be installed in pairs with each
supplying 72bits of the data. Dataram do 3rd party boards which are fully
supported by Compaq. Cheap too. ( 400 UKP for 512Mb)

I believe that they are double-buffered ECC SDRAM (the low
density memory works quite nicely in 440LX motherboards ... not
sure if it is PC100). Dataram makes a replacement part for it that
actually has a high enough density to be interesting ... I think
that the Kingston parts were all fairly low (this may have changed,
I tend to just use Dataram as they have a nice edu discount).
For some details, see:

So, I have the vague feeling that the PC100 ECC SDRAM the user bought
is not quite what he thinks it is as it doesn't work and, from the
above, it would suggest otherwise.
Still, the suggestion from Joe was to move to the next chapter of BOFH
and consider 3-phase supply to the user and removing support from him
(I wonder in which order...). It also seems that Dataram is popular!
Thanks to both for replying.
