105917 2002-12-14 07:24:00 I "play"with an old pentium pro 200 that has been reduced to running on only 2 x 16mb of 72 pin edo ram.I'm looking at the advts/auctions to get another 32mb & i'm a bit confused.Must any additional ram be the same make as already in the machine? eg samsung.Does 60/70ns make a difference to what will be ok for me? Where the word simm is used does that make a difference? Is all 72 pin edo ram double sided with 8 chips on either side? what will give this computer a boost? Your help please.Dave in chch amyes5 (2773)

Additional ram doesn't have to be made by the same manufacter as the current ram in your system - It just has to be compatible with your motherboard
Where the word SIMM is used does not make a difference, however (from memory - so I could be wrong) not all 72 pin edo ram is double sided with 8 chips on each side.. As each chip stands for 1MB of memory (I think that's how it worked in old ram)

105919 2002-12-14 21:18:00 I updated an older computer (P166) using 128MB chips from DSE. The only issue was the MB's inability to use single sided memory and I had to buy double sided (memory chips on both sides) otherwise only half of the memory capacity was recognised.

Faster memory can run slower but not vice versa so unless your MB is particularly critical in its memory demands 2 x 128 MB double sided chips would probably work fine. I wouldn't waste time adding 32MB of old memory. At today's prices take it up to 128 or 256MB.

If in doubt, post your mother board model details and someone will soon come up with a definitive answer.

105920 2002-12-15 01:17:00 If you are restricted to 72 pin SIMMs, you will need EDO . (You can use EDO ram with Fast Page, but not the other way round) .

60nS/70nS: if you have 60nS get 60nS; if you have 70, use whatever you can get .

If you have parity ram, get parity ram . You can tell by 9 chips (or a multiple of 9 chips) versus 8 chips . {Or 3 chips (or a multiple of 3) versus 2} . Yours will be non-parity, because you mention "8 each side" .

Chips on both sides: They use both sides if they need to get double the capacity on one unit, with a particular ram chip . It doesn't matter . "Single sided" SIMMs will probably be later production of a given size .

I got a quote from DSE a while back, maybe 6 months, and for 2x 64 MB Chips (128MB RAM Total) that would have cost well over $400! Why not build a new PC for that amount?!

I'd suggest that if its EDO RAM, You're gonna be hard-pressed to find anything more than 16MB Chips, maybe if you're really lucky like I was, I bought 2x second hand 32MB Chips for on $50!

My 2c worth anyways . .
