Having put the Z620 back together I checked that the memory was in the
tight places, it's dual Xeon with 12 memory slots and, of course, works in
pairs.

I used the sheet from HP to ID the slots and then tried to use CPUz, SIW,
Speccy * Task Manager to check, they all come up with different answers!

Incidentally none of the methods I tried nor the HP sheet seem to think
Bargain Hardware's use of the slots was right!

I have asked on the HP forum but does anybody know a definitive way to
tell which slots I am using?

Fill them all up?

HPs I've worked with have (like Dells) a sticker on the inside of the
case with slot labelling. Otherwise, just found the actual guide - which
wasn't on the Z620 product support page, but DDG managed to index it. It
has all the labels!

Many thanks Jaimie :-)

The area where the sticker was is just a few strips of glue now, I can
print the page from the link you sent me and stick that there.

What confused me was that CPUZ said slots 1, 8, 9 and 12 were in use when
I had religiously followed that guide. However, CPUZ is right, with a
strong enough magnifying glass I can just about make out the DIMM slot IDs
and they are 1, 8, 9 and 12.

I will work on the basis that since I have put them in the order the
instructions say that must be OK, there are no warning messages.

Thanks again!
