Hi all,

Thanks for the answers from the follow system adm/managers (in chronological order),

Edward C. Zimmermann
SOMESH
Kumara Swamy-WIPRO-NA
Law Hon Man
Gruss, Dieter Gobbers
Michael Galloway
Matthew Stier
Rick Reineman
Rich Kulawiec
John Reynolds
Mark Bergman
Glenn Satchell

here is the answer in short:

Sparc4 and 5 can exchange RAM but not with any sparc10/20 or utlra.
Sparc10/20 can take Ultra RAM
Ultra can take Sparc10/20 RAM providing that the RAM speed is 60ns.
