9595s & Max Performance
David Longley
would like to upgrade the CPus and RAM to max. I believe the 9585s are
max 64MB and DX66/2? But what about the 9595 (95A). The standard CPU
seems to be either P60 or P90. What can they be upgraded to and how?
Does the 95A ONLY take ECC RAM? I've tried other types and just get an
error code.

Apart from that: Parity maxes out at 64MB (8 x 8MB) on the 95A, while ECC can
be at least 128MB (8 x 16MB on P60/66) - if you manage to get the proper SIMMs
anywhere. Only 70ns modules are supported and these must have IBM presence
detection.
The "big" 9585 models -xKx and -xNx allow to install 8 x 32MB Parity / 70ns for
a max of 256MB .... but no ECC. See Louis' page for details on the 85 "ECC over
Parity" structure.

Another question - the card on the 9595-BOC I have is an IBM SVGA-NI -
how do I install that under NT 4? I've downloaded the drivers but they
are no use, VESA and cira 1992.
At the moment I'm running on 16 cooours and 640 x 480 and I need to go
to at least 256 and 800 x 600.
Where can i get some ECC SIMMS from then <g>..
Also, what's the max cpu they can run......
Thomas J Watercott
its running 256mb
Peterwendt

Ah .. well .. if it is a P-90 platform.
This is the same as in the Server 500 and supports 32MB ECC. The P60/66 does
not ... at least not if you query the "supported memory modules list" from the
machine BIOS with the Netfinity manager ....

What machine ? The 9585-xNx (big) or the "small" one with the soldered SX cpu
... or the 9595A with various boards.
Depends on. I run my 9585-0NG with the Kingston Turbochip with the AMD 5x86-133
for about a year and a half. At 128MB RAM it is a good server - but I would not
put additional software on top. And no DNS server ... that takes more
performance than this thing can give. Did not test it with the PODP. It worked,
but I needed the chip for something else.
The small 9585s with the 50-pin onboard SCSI cannot be upgraded that far. Don't
know what they take - a 487SX most likely or SX-Overdrive. IIRC someone tried
the Kingston Turbochip on it to no avail. Simply did not work.
>Also, most urgent, I have a n SVGA-NI card in - and I'm rnning NT 4,.
>It's not detected. Drivers from IBM are no good..
The card is basically a VGA card. The chipset is from TI and undocumented.
There are some OS/2 drivers that allow 256 colors at 640x480 and 800x600 / 16
colors at 60Hz refresh and 1024x768 / 16 colors at 43.5Hz refresh - and that
was it. Currently I am testing the same card under Linux - but there is nothing
that at least fits "so-so" (means: for 640x480 / 256 colors). The chipset is
totally proprietary and must have been rather cheap for IBM ... the thing has
512K VRAM and an 80MHz RamDac from Inmos ... that should do the trick. But the
internal registers are different to anything I know. And I really dislike the
idea to "reverse engineer" the OS/2 drivers !
>I need to go to 256 cols and 800 x 600..
>Can you advise.
Use an XGA-2. The XGA-1 does not support 800x600 and there are no alternatives.
There were a lot XGA-2 offered N.I.B. just recently on the newsgroup for a good
price (20 AFAIR)

I'm sure you already know this, but the 9595 with P60/66 supports 256MB of
ECC ram just fine. I've been running such a beast for almost two years.
The memory is properly identified and tested by the diagnostics, and
further, is listed as supported for the Pentium models on IBM's web site.
Here's the reference for the 9595-OQT:

Since that's such a lengthy URL, here's what it says about memory:
16MB std (2 x 8MB, 70ns) / 256MB ECC, 64MB parity max / 8 sockets
ECC memory standard.
Memory must be installed in matched pairs.

you regularly check the auction sites. I've managed to find enough to put
256 MB each in two 9595A systems, and the Server 500 I just bought has 224
MB (6X32, 2X16).
The price has been going down, as well. I got the last 256 MB for under
$200.

How do you manage this? I have yet to see any 32MB SIMMS on EBAY, and
keep asking here every month or so and have had no offers.
If you see any more, please let me know.

I just did daily checks for a few months--eventually, everything turns up on
eBay. You may have to search under various categories--it's amazing how
often stuff is incorrectly described and categorized. As you know, if
you're willing to get up very early or stay up very late, you can often get
some surprising bargains. The next time I see some 32 MB ECC simms, I'll
post a reference here.
Also, it's often cheaper to buy entire systems than components. I paid $300
(plus $35 shipping) for the Server 500, and it comes with P90 complex, 224
MB of ECC ram, Cheetah raid adapter, two Adaptec SCSI cards, three 1 GB
drives, and some NICs, etc. I intend to junk the box and use the components
in my 9595 systems.
Of course, I've missed even better deals--I once saw a similar Server 500 go
for under $250.00. And I think Peter gets them free--he finds them in
dumpsters or gets paid by customers to haul them away.

Yup, it's definitely that Netfinity poobah told Peter's
machine of its limitations. The 9595-xNx here with the P66,
148 MB of ECC RAM and 2 parallel ports, but without Netfinity,
runs steady as a rock. That's with BIOS v10 and two 32, four
16, two 8 MB ECC SIMMs.

NOT with the 6 other 8 meg NON-ecc simms. Had to go back to just 64
meg.

That's not just some SLC desktop box you're talking about tossing
out there CB! It is the last great pure MCA box ever made!
Have a heart and save that noble box. If you have to take out
some goodies, well fine, but you'll find lots of people that will
pay over $100 for a minimally configured Server 500 box.
Being capable of handling 18 drives is no mean feat. It's
impressive even if you drive it with a P66 processor.
Taking a completely tricked out system and reselling it as a
basic system is something I've done often enough, but it still
leaves an MCA system in circulation, and the other parts
benefitted another MCA box somewhere.
A friendly suggeston from a PS/2 lover that wishes you all the
best....

I wish it were that easy.
My customers tend to keep them for themselves. Only managed to pull out some
T3-9595s a 9595-S23 (euro -1NT) a 9595-S30 (euro -1PT P60) and my Server 520
with the unlucky Micronics Dual P-133 PCI/MCA board. (And Mylex DAC960P PCI
controller ...)
No 500 boxes. Nowhere.

I'm looking for some too (32MB ECC SIMMS). Is the P233MMX CPU a straight
drop in for the P90 (surely not)...

Don't worry--I won't really junk the Server 500. I'm just going to strip it
and store the carcass until later. I'm going to be moving soon, and one of
the criteria for my new house will be sufficient room for a big computer
lab. Like half a basement, or similar. And I want to put in a soundproof
server room for noisy monsters like the Server 500, as well.
But that's a few months away.

Don't make the mistake of stopping at "half a basement", go for the

Now that's the spirit.
I personally think we can solve this problem of PS/2
computers going to landfills by just having every PS/2 user
store 100 computers & monitors in the basement / attic until
they could be reintroduced during an age of new
enlightenment!
