OK, I got a really nice condition Thinkpad 600X with a 500mhz processor from a friend and installed Windows XP. The PC runs fine but I get a lot of hard drive activity. Thinking it was the OS using virtual memory I decided to upgrade the RAM. I picked up two 256MB PC100 low density sticks of RAM and installed them. Now when I boot I get a 255 error, which is a memory error.
I have tried each stick of RAM individually, in both of the RAM expansion slots with the same result. I flashed the BIOS and still no joy.
Is the problem the low density configuration? I had read that the low density RAM would likely be more compatable than high density. True?
Any thoughts or help would be greatly appreciated.

Welcome to the forum!
Your DIMMs have 8 chips per side, for a total of 16 per 256MB stick, correct? What brand are they?

My best guess is that the RAM you've purchased is of substandard quality, making the good old 600X unhappy...try locating the original Micron RAM (IBM-branded) for these machines, either on feebay, or post a WTB ad in TPF's marketplace:
