is expecting EDO and you put SDRAM in there
We are talking about PS/2 SIMMs. There
are no SDRAM PS/2 SIMMs, only FPM
and EDO. As the SIMMs work in a Indogo2 R10k I asume they are FPM and
that is what the Indy should accept. But it seems thay are just to big.
Yup... that's the problem. It's FPM to go with all the ARCS SGIs that
have 72pin "PS/2-memory" slots. No need for ECC RAM, no support for
EDO at all.
My understanding so far is that Indy and true R4K Indigo 2 share quite
a lot of concepts on the hardware level. R5K Indy is basically the
same machine, but with a different PROM and CPU. All these old
machines apparently can't go beyond 32MB per SIMM resulting in a max
of 256 MB for any Indy and 384 MB for R4K Indigo / Indigo 2.
Right from the start only the 64bit machines like R8000 or R10000
Indigo 2 support larger modules, leading to the GigaRAM Indigo 2 at
least.
Aside from the apparent great feeling of running a Crimson my
favourite for months is the R10000/195 High Impact Indigo 2 I have.
Runs not too hot, not too loud for my taste... and delivers decent
performance even under IRIX 6.5.$somewhat.
As for 24/7 business a R5000 Indy is my choice. Silent and with low
power profile, yet more than fast enough for what I do on my server on
a daily basis.
