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!
