I picked up a
pair of SM91-2's on eBay years ago. They do indeed
work in
an SS20 -- for a while. Then I think the heat
catches up with them...
Every time I installed them (I must've tried singles and pairs) it
would
be fine, I'd go do something else, and
I'd come back to a locked up
machine.

I have a SS20/2xSM81 as my SMP Sun- haven't used it much yet but if in
general they have stability issues I should probably do something else.
I ran a SS20 with Dual ROSS 125MHz CPUs. They got seriously hot. Also ran
another SS20 w/Dual SR71s. Both the SR71 and ROSS needed an unique EPROM
upgrade to run without "freezing" (hanging) the system. Perhaps that's the
issue with your SM91-2 (as opposed to heat)???
You might want to post a query to the suns-at-home at net-kitchen.com list to get
the EPROM upgrade if required for the SM91 (if someone else doesn't respond
on this list with same).
Cheers,
Lyle

I have had the same experience with 80MHz CPUs in my SS20. I finally
had
to settle for 2x50MHz and some stability instead.

I've been nice and stable with a pair of SM71's. What I think would
be cool to try is a pair of the dual CPU boards for a quad CPU system
(I think they were 50Mhz). I ran my SS20 like this for quite some
time before I upgraded to an UltraSparc based system.
My big problem is with the hard drives, most of my SCA drives are
7200 or 10k RPM, which tend to run to hot for Sun Pizza boxes, and
the bearings seem to go out.

Those would be SM100s. Made by Ross, Cypress chipset, 40MHz, no
L2 cache, and ungodly slow. A system with two SM51s will run rings
around a system with two SM100s.

Oh, THOSE...I thought they were only used in the SS1000? Or am I
getting them mixed up with another module?
The SM100 really is a piece of garbage, though. Sun knew
(according to a former Sun employee) that they should never have sold
them, but being able to say "we have a quad-processor machine" was
worth quite a bit to them at the time.

They might have only been *sold* in the SS1000, but I've definitely run
them in the SS20. I suspect the configuration would probably be called
something similar to SS20/514.

Wow, that's a new one on me. I've used more Sun hardware than
most (not trying to sound like a weenie), and have never seen one of
those, at least not that I can recall.

While they're something I've wanted for years, I have to admit that I
have absolutely no use for them, and they would most likely be better
off going to someone that would use them. I haven't powered on my
SS20/712 in nearly 5 years. Now if OpenBSD supported multiple CPU's
that would be a different matter. :^)
Now the real question is which is worse, the heat from a SS20/514, or
a SunBlade 1000! The SunBlade puts out so much heat I only really
use it to low-level format HD's for my VMS box. :^(
