I'm trying to find out what the maximum memory is that can be installed
in a 550 MHz Sun Fire V100. I've seen some references that say that
with a 550 MHz processor, 1 GB per DIMM slot can be addressed. On the
other hand, everthing seems to indicate a 2 GB max total memory. The
V120 (very different mainboard, I know) can go to 4 GB. Does anyone
know if the V100 is truly limited to 2 GB?

Please remove the "nospam" from my address if responding via email.

Well, any reason not to take the handbook's word for it:

Normally, no, but the same site shows the Ultra-5 limited to 512 KB, and
that's not true.

I've been told that you can use 1GB modules in a V100, but that the
machine will only see 2GB in total, so this doesn't help us.

Sunsolve also says that the SPARCclassic can only use 16MB SIMMs,
but one can apparently put 2 32MB SIMMs in the first bank, and
have 128 MB of memory in total.

Depends what you're asking.

If you're asking what is the maximum DIMM size which is supported - it's
512MB (total memory 2Gb).

If you're asking what is the maximum DIMM size which will work - I've got
no idea!
