Max Ram on IBM Aptiva.

I'm not sure if this belongs in overclocking, but if it's not it should be. How much ram can you stick in an IBM 5137 with a k62 200? The motherboard manual says 64mb pc 66 max. I bought one at a garage sale today for $15.00. I wanted the OIP 52x cdrom someone had upgraded it with. It had 2 DIMM slots and advertised a wopping 24 MB of system ram on the front sticker. It was a bit dodgy and took three tries to load Win98SE, but finally it got it right and finished installing with no conflicts, but bios and windows both reported 272 mb of ram. Bios also said I had one 16MB DIMM and One 6MB DIMM!!! I shut down and took a closer look at the ram sets. One had a loose clip and I pulled it out. It was a stick of 256mb PC133. Now I knew why it took so long for the boot memory test!

It's probably an old K6 200, the long forgotten K6-1 (Never called that but I'm sure you understand.)

One issue that system may have is that it can probably only cache 64MB of RAM. With 272 everything is probably loading into the uncached RAM and seriously slowing the machine.

What is the chipset on the mobo? That would be the important thing to check for if you want to know how much memory it would recognize and how much of the memory is cacheable! So, if you could give us the info on what chipset the mobo has, I should be able to give you more info on what the mobo can support on that system!

Do you mean Aptiva 2137? Go to www.crucial.com and look it up. Once you've chosen the model number, it will tell you how much RAM that board can take.

Actually, I did that after first checking the IBM site. They both say 32mb PC 66, Max ram is 64MB. Them IBM's are tougher then you might think. It was working but like Rugar pointed out the max it could cache was 64MB. That's why it was crashing with the 256MB stick in it.

In this case chipset is not #1 thing here to how much mem it can handle. Its the cpu-as in its limited to how much mem it can address fast enuff. Over 64mb and it wont ever get to it! LOL Like sticking 256mb ram on a p 166mhz is a waiste.
