I have an old Enterprise 3000 with two 250MHz UltraSPARC II processors. Now
I'll get two Sun UltraSPARC II 400MHz CPU modules with 8MB Cache (P/N
501-5661). Will these run in the E3000? Do they require any certain firmware
and/or board revisions?

Yes,

Are you adding a CPU board or will you switch CPU:s?
You need clock board 501-5365 to provide a 5x (5x84=400MHz) frequency.
Update to latest prom patch before installing them.

If you have cpu-board 501-2976 only 2MB cache will be used (X2600A),
if you have X2601A or X2602A cpu-boards all 8MB will be seen.
If you have older clock board than 501-5365 the cpu:s will be recognized
as 336MHz I believe.

I had a Sun E3000 with the following spec:

1x501-2975 clock board
3x501-2976 CPU/memory boards
6x501-5235 400 MHz / 8MB cache CPUs

In this configuration (i.e. with the slow clock board) the CPUs ran at
336MHz. The clock board was then upgraded to 501-5365 and they now run at
400 MHz. I'm a little concerned about the cache size though - prtdiag -v
shows 8MB cache per module but the sunsolve page indicates only 2MB will be
used - is this the case?

Many Thanks,

James

I want to switch. The E3000 currently has two 167MHz 1MB Cache CPU's on a
501-2976 CPU Board, so I will have the 2MB cache problem. But I have an
501-4286 clock board from which Sun says it's a 83/100MHz clock ("Clock
501-4286 supports 167, 250, 336, and 400MHz modules"), so hopefully I'm at
least fine with that. I'll post my results as soon as I receive the CPU's.

Thanks for the help!

Actually you would be fine on a E3500 with 100MHz bus. But with a 83MHz bus
you really need the 5x multiplier! But we'll see! A clock board is usually
really cheap.

Hmm, from what I found out until now my clock board is 100MHz safe, but my
I/O board and my CPU board are not. Seems I have to replace the CPU board
simply because of the cache issue so I can get a 100MHz one, so I need a
100MHz CPU board and a 100MHz I/O+ Board. Do You have an idea how much I
should pay for such boards in Europe?

But then, even at 336MHz the CPU's are much better than the 167MHz USI I
have currently...

Last time I looked the cheapest I found was about $1000 ea.

Can anyone confirm the cache limitation is an issue? I've just run a bunch
of tests on my E3k with 400 MHz/8MB CPUs and the 501-2976 board and as far
as I can tell, all 8MB is being used,

Thanks,

James

Oops, that's more than the whole system is worth...

Hmm, when I get my CPU's I'll check that. I wouldn't be too unhappy with
only 4MB _if_ the system otherwise runs fine. How did You check the cache
size?

Forget 100Mhz - your E3000 backplane only supports up to 83Mhz.

What you need (as someone else suggested) is a 5:1 clock-board. Using
this the backplane, all CPU boards and all IO boards run at 80Mhz, and
the CPUs run at 5x the bus speed, or 400Mhz.

I'm not sure about that since Sun says my backplane is 83/100MHz...
