I’m not throwing them out at this time. I have a total of 640.0 mb and the system seems to run fine at this point. When I do throw them out, I’ll just get another 512 PC100/133 to match.
Wasn’t suggesting you throw it out. I was saying take them out, see if your BSOD install problem goes away. When installing an OS, any OS, pare the system down to least amount of stuff. No extra cards, etc. Mixed memory, in general is one of the first things to look at on BSOD.
You may not have a problem with ME, as it’s entire max memory footprint falls inside of 512mb. Depending on how the chips are installed, 512mb could be entirely on the one chip, not spanning all 3. XP however will attempt to use up to 2gbs for the 32 bit home version, meaning the memory footprint will encompass ALL those chips. If there’s an issue with incompatibility between them, XP will barf out.
As a simple way to eliminate that as an issue, and believe me, I’ve been a tech since the 80s, it won’t be the first time it’s happened, you simply pull those out for now and try the install. If it installs, you’ve got the answer, if it fails, it’s something else. Either way, you don’t know until you know.
