Which memory type do I have in a 9117-570 2

[DonDavisFCB]

I have a 9117-570 and need to order more memory for it.
I have been told that I need to know if the currently installed memory is DDR1 or DDR2 because they cannot be mixed. How can I find out wihout cracking the case?

check the vpd for the CCIN number of your dimms:
lscfg -vp|grep -p DIMM
note the "Customer Card ID Number"
then go here:

and search (Ctrl + f) for the 4 digit CCIN and it will tell you the type and size of your dimms.

DDR2 is 3volt memory and is only available for high end (1.9Ghz or 2.2GHz processors) p5-570.

If yours is a 1.5 or 1.65GHz model it will be DDR1 (5volt) memory.

p5wizard,
Your voltage differences appear to be in question.
My 3rd party vendor at first knew nothing. Now he is quoting this:

PC133 – 3.3v
DDR1 – 2.5v
DDR2 – 1.8 v

Do you have a reference I can point him to?
Thanks!

Well, p5-570 processors come in "standard" (which use DDR1 memory DIMMs) or "low-voltage" - for 1.9 or 2.2GHz only -(which use DDR2 DIMMs).

I was googling after your question yesterday and came across the 5V and 3.3V values, but can't find that info right now.
