I had HP 9000 L1000 server with 512MB of RAM. I bought 2GB RAM kit from
Kingston , installed it and everything seems to work correctly but when
I check with cstm, I get following:
....
Hardware path: 8

Basic Memory Description

Module Type: MEMORY
Total Configured Memory : 2560 MB
Page Size: 4096 Bytes

Memory interleaving is supported on this machine and is ON.

then:
WARNING: Current loading of DIMMs failed thermal loading order check.
Operation with this DIMM loading could lead to unreliable
system operation and degraded device lifetimes. Refer to
DIMM
loading rules and re-distribute DIMMs.

What does it mean?

Doesn't like the physical layout of the memory as installed. The rules
are:

* Memory must be installed in DIMM pairs.
* The capacity of DIMMs within a pair must be the same.
* Install DIMMs with the greatest capacity in the lowest t
numbers.
* Install DIMMs the following slot order: 0a/b, 1a/b, 2a/b, 3a/b, and
so on.

You've populated slot pairs 0 and 6, but not 0 and 1 (as expected). Those
numbers can be found on the memory carrier board. Move the modules from
slot(s) 6 to slot(s) 1!

Enjoy,
Ulrich
