More memory!

Today I got a pair of 32MB 72-pin memory for my 8100. I believe once these are installed the memory will be maxed out.

 
Nice... Max memory = The best performance you will get. I coulda sworn they had 128MB memory modules for machines like that...

What IS the max for the 8100 though?

 
there are 128MB 72pin simms coius but tehy wont work in the 8100...

you could be lucky to get 128MBers to work in a 6100 or in the LC475 and 575 maybe.

 
Now all I need is the cable/adapter to go from the PDS G3 card to a HPV or A/V card. Right now it's using built-in video since the SuperMac Thunder/24's output is a bit fuzzy. That and the drive bay cover for the CD-ROM drive.

I guess that I can't complain too much for $7.50.

 
I thought 72 pin sims stopped at 32mb for some reason. my crappy old dell, which takes 4x72s has a max of 128mb. I have half that in there right now.

congrats on maxing it out, I have only one of my macs maxed out, but I plan on doing the same to my pismo as soon as I can aquire another 512mb stick.

-digital ;)

I would love to max out my Sawtooth and Blue/White G4. I'm getting there with 768MB on the B/W and 640MB on the Sawtooth.

Not really. At least not with (the classic) Mac OS. The memory model is designed in a way that software does a lot of its own memory management because it is probable that the OS will tell it that it is out of memory. I think that this created a situation where developers created much more memory conscious applications. There are, of course, exceptions to that rule. I would imagine that Photoshop is a heck of a lot more efficient while dealing with large images if it doesn't have to get creative with memory management on its own. But that isn't run of the mill stuff.

Modern operating systems do tend to benefit from extra memory. Not only because they are memory gluttons to start with, but because they do interesting things -- like cache the file system. (Well Linux does, and I seem to recall hearing that Vista does. Mac OS X, I can't check.) Of course, software is also a lot less conscious of how it allocates memory too, because software developers know that modern virtual memory implementations are fairly efficient. That being said, you still have to deal with diminishing returns.

That being said, RAM is relatively cheap these days. So, I guess, why not?

 
My feelings exactly.

RAM modules these days are large, plentiful and dirt cheap.

Unless anyone here is paying the $400.00 bucks a 128MB stick of EDO 72 pin RAM like it cost back in the day, I don't wanna hear no bitchin'. I have about 16 of those sticks myself. You can pry them from my cold dead fingers. I had the advantage of working as a tech in a mom and pop shop during the transition from 72-pin SIMMS to DIMMS. As such customers would trade in their older RAM modules for discounts on newer modules because they were faster. I was able to purchase them from my boss for a nice deal and I have had them ever since. A few died and were replaced either in conquests or e-bay deals.

I also have a cache of 32MB sticks because as we all know, the 128's don't work in a lot of machines.

If you ever search for wholesale lots, look for 72pin sticks. I bought a lot about 3 years ago with about 150 so sticks of various sized 72pin sticks. I'd say roughly 90% of them worked. The rest were turned into keychains and given away to friends.

I remember when 4MB 72-pin SIMMS were about $200 each. I also remember paying $150 for 256k worth of DRAM chips.

And I went uphill in the snow both ways! [:D] ]'>

I checked the memory and apparently I have two banks of 16MB SIMMS. It's a good thing I got another pair of 32MB SIMMs today to actually max it out. Before it would have been something like 224MB or so.

Even though the only card in my 8100 is the G3/400 upgrade, I'm not looking forward to taking it apart yet again.

 
8100s aren't that bad. I used to own one and although it was easy to take apart (for me at least) it drew little blood compared to other machines I have worked with (x86 Mostly). In fact, you know what they say, you're not having fun 'till you're bleeding :p

 
Taking the 8100 apart isn't bad, but doing it to test each bank of RAM is. When I brought it up to 200MB I took the components out of the case and laid them out on my desk in order to be able to test the RAM I had and not have to remove the logic board each time.

I always seem to get cut working on computers and cars. You aren't doing it right if you don't. :)
