I had 2G of RAM, but the system can take up to 4G. I plugged it in and indeed, the bios tells me that 4G is present. However when I boot, the kernel does not find it all. The system is a 10 year old 686 and from dmesg: DMI: Dell Inc. Precision WorkStation 370 /0 M3849, BIOS A04 03/16/2005 [ 0.000000] 887MB LOWMEM available.

I suspect a kernel misconfiguration, but what?Heya, some thoughts on that: 1.) Are the RAM-modules the same? FSB, manufacturer? Double - Single sided? 2.) Did you try the modules on another system? 3.) Check if the MB supports Single - Double sided modules and if on both slots? 4.) Some 686 CPU's don't play well with PAE. Had some of them during my time. And yes it's definately a HW problem. I read somewhere in the replies to update your BIOS. That might help. Had some of those as well.
Thanks for the thoughts, but for a 10 year old system, it's more effort than it's worth to fix. 3.1G of ram does what I wanted (stops swap). I don't update this system very often, so if I really need more capability, I'll probably just replace the whole system.
Actually this is my least capable box. My development system and laptop are both quite a bit more powerful. My core2 has 10G of ram and my i7 laptop 8G. It's great for email, browsing, and ssh to other boxes though.
