Adding Memory to rp2450

Well it is time to increase the memory in our HP-9000, rp2450. It has 4-512Mb memory sticks and 4 empty slots for more. I know they have to be installed as pairs.
Can I use a pair of 1 GB memory sticks or do I have to stay with 512s?

The answer is in this document.

I'd say yes, but you should verify.

Yes, you can mix RAM of different sizes as long as they are installed in the required pairs.

Re: Adding Memory to rp2450

This document has the configuration rules on page 125:

http://docs.hp.com/hpux/onlinedocs/2411/rp24xx_customer.pdf

"Memory Configuration Rules:
rp24xx servers have 8 slots (4 DIMM pairs) on the system board for memory DIMMs. These slots are numbered 1 through 8. The following rules govern the installation of memory DIMMs:
- 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 slot numbers.
- Install DIMMs in numerical order starting with slot 1 (1, 2, 3, etc.)"

So if you purchase 1GB DIMMs, install them in the #1 slots, move the smaller ones to higher slots.
