Dear Gurus,
thanks for your answers, and sorry for the delay for this SUMMARY.
It seems to most of you that compatible RAM works well .
Here the messages I received (sorry if I lost someone) :
It seems that RAM manufacturer had a service agreement with DEC, so
that you could still call DEC Tech Support and get Field service (even
though you weren't using an original DEC part) - at NO extra cost.

I suspect that if you buy nonDec ram it will probably work OK. However,
neither Camminton or Kingston would confirm that their memory
supported ECC. Before buying, ask if their memory supports ECC. Let me
know their answer.

we use only compatible ram for all our workstations (16 alphastation 255 and 8
personal workstation 433) and had no problem so far

That is all we buy now for our 2100s and it has worked great so
far. Have not had to add new ram to a 4100 yet.

Hi! My experience tells ms that DEC uses simple 72 pins SIMMs. In older
machines they used to use SIMNs with parity (like IBM PCs used), in newer
machines you can use normal EDO SIMNs. So I sugest that you do the test,
open the box, check the access speed of the SIMNs installed and install
similar SIMNs, I had no problem doing it with a AlphaStation 255.

once a distributor sold me non Dec-Rams which didn't work. After
inspecting the new rams I found out, that the distributor hat mixed
different brands and types. I called him and he replaced the rams. Now I
have just one brand and no problems.

I used to work for DEC as a field engineer. One of the biggest problems
I had was with 3rd party memory. It got so bad, that we stopped
supporting systems with 3rd party memory.
Were these boards you are looking at made by DEC originally than
refurbished by someone else? Be VERY careful about the vendor and
source.

We use Viking Memory exclusively on our Alpha systems. There have been
no problems and the memory has a lifetime guarantee.

I think my own experience could help you.
1 month ago, i've tried to increase memory size of a
AS1000A under DU40D. after many trys, i have found
that this box need 36bit SIMM modules ( and not
32 bit or false 36bits module ). I Dont know what
type of memory is in an AS4100.

We almost always buy memory for our systems from someone other than the system
manufacturer. Our purchasing group generally buys from the cheapest source,
unless there's a known problem with a particular manufacturer or vendor. As
far as manufacturers go, we've have good success with Kingston in our Alpha and
SGI systems.

I'm using both PNY and Kingston memory without problems. They also
know what you need...
Gyula Szokoly <szgyula_at_tarkus.pha.jhu.edu>
It is likely you can get DEC to match other vendors' RAM price and have the
best of both worlds.

Thanks to Giorgio Mantini - ESRIN/RS/E Systems Administrator x685), too
He replyed in Italian and told me to be carefull since DEC does'nt
support such non-DEC RAM.
Thanks to the whole family of alpha-osf-managers
