Finally, I had to replace the motherboard and
after that it started recognizing 4GB Memory.
Thanks a lot!

Hello all,
I have ultra 450 Enterprise server on which I installed 4GB memory.
It shows only 2GB memory while booting.
I installed 256MB memory modules and all banks of A, B C and D are full
so no question of order even.
Also tried to reshuffle memory inorder to confirm that modules are
working fine. Memory modules are of Make Kingston.
Sun web page says that Ultra 450s are capable to expand the memory upto
4GB.
At Ok prompt if I type command banner, it says 2048 MB memory and
openboot 3.20.
Any ideas why it is happening. Is there are any issues with OpenBoot
version.
Note: On the same machine I faced the problem of NVROM password which is
fixed by replacing the NVROM from SUN.
The output of memconf is as below. It still shows the few slots are
empty even if there are memory modules installed.
./memconf
hostname: ultra450
Sun Enterprise 450 (2 X UltraSPARC-II 296MHz)

Appreciates all your valuable suggestions and time spend on it.
