Hi,
I want to upgrade the ram on my Ultra 5 (currently running Solaris 9)- I've seen part no. PN 370-3798-01 for sale.
I've checked on
Sun's website and it says the above module is a 50ns DIMM and was originally only in Ultra5' s that had 360MHz or faster UltraSparcII cpus and 24bit PGX graphics.
As I have the older 270MHz Ultra5, I assume that the existing 128MB of ram is slower 60ns ram. What I want to know is would there be any issue in using part no. PN 370-3798 to upgrade my machine? Will it simply run at 60ns? Should it be compatible if I was to replace the existing ram in my machine with this ram, if I can't add it to the existing memory?
Cheers,
Steve
