[parisc-linux] Which Memory to use on a 715/80?

[Christian Weerts]

My 715/80 has a memory problem. Perhaps i need new memory.
Which is the right one to buy?

Thanks! That's what I'm looking for the whole last week.

Can I use other SIMMs with ECC from any other contributor,
or is the use of these SIMMs recommended?

Well, don't think any other manufacturer made memory for the 715
series.  I have looked at Dataram and others, but they only seem to
have memory for the D,K,N,L, and A class servers.  What size are your
simms in your box?  I have some 8MB ones laying around here that I'm
not using.  It's the same memory that is used in the 712's.

I thought Kingston *did* (maybe no more).
Might still check there.

I recal by head (and might be wrong) to have used pc-based memory modules in
a 712/80. There was something with parity (it needs it or it hates it, don't
know).

Try what the bootloader says if you fit it with pc-based memory modules,
that have the same physical lay-out. (edo-ram is a term that comes to mind,
try it or it's predecessor).

I might be totaly wrong here, in those days (a former job) I was using both
SunSparc stations and HP 712 machines.

I don't give any guaranties....

You usually hear that HP uses similiar form but completely different
ram. But that's mostly on 715/735/800, maybe 712 was different. That
would be a pleasant surprise.
Mostly you always want parity. I would doubt anything explicitly
demanding no parity.

EDO AFAIK never occurs together with ECC so that's the word to avoid
when looking for ram for older workstations ad servers.
36-bit FPM True-parity ECC SIMMs are what work in, for example, DEC
Alpha AXPpci, Multia, SGI Indy, Indigo², matching Challenges, IBM RS6000
7006 and other machines of the era and most(?) pc's. No kind of EDO ram
works.

Sparcstations mostly use weird rams like JEDEC DIMM's apart from the
very old ones that use 36-pin simm's that seem regular.


This is what I remember. No guarantees either.

715/725/745 and the 712 all use the same type memory.  The 730/735 used
another type, and the 755 used a unique type.

Harri is right here, I was mixing SunSparc and HP-PARisk architectures. The
712 memory does NOT fit (without a hamer).

Sun Sparc ELC and SunSparcClassic (and similar Sparc 4C architecture?) can
use the same memory modules as 486-PC's. Those are NOT edo ram as in
pentium-pc's, however they do fit... It might not be what Sun tells, it is
wat is currently running at home...

I've tried EDO ram in a SParc Classic but it does not show up. After a short
test (15 minutes power on and try to use it) I experienced no damage on both
processorboard or memory. Then, again: no guarantees...

Now I know where the name "tucows" comes from ;-)

I've tried FPM Parity RAM in my 712 and it didn't work. I'm shure it's same
on 715,
but you can get it quite cheap on eBay.de (Computer/Workstations).
I have 48MB (6x8MB) spare modules, if you are interested, i sell them to
you. Send me an off list mail.

That's not true, there are some EDO Rams with ECC, 'though rather rare.

Sun SPARCstation LX/ZX also use 36bit (true parity) FP-RAM. The
ones you find in old 486 will just do fine, if they have ECC.

EDO Ram is not supported on SPARCstation classics/IPC/IPX (sun4c) and
SPARCstation LX/ZX (sun4m). You NEED FastPage mode (aka "normal", pre-EDO) =
RAM.
IMHO that's strange, since EDO RAM is supposed to be backwards compatible
IIRC. Or was this just a feature of 386/486 Motherboards?
