The mobo here is DFI LanParty (something PCI-E) which has been happy with 4x512MB dual-sided DDR-400 (should be reduced to 333 tho) after diabling the 1T timings.
Yes, you should either reduce your synchronous timings to DDR333 (PC2700) or reduce the number of DIMMs to 1 per channel (2 total).
JEDEC specifications only allow for 1 DIMM per DDR400 (PC3200) channel, or 2 DIMMs per DDR333/DDR266 (PC2700/PC2100) channel.
The only exception is if you use registered DIMMs, which allows twice as many to be used.
OK, just nuked the box. Did a reformat and newly install of CentOS 4.1. No changes to the BIOS or mem timings or anything. Now I am able to compile.
Guess it wasn't a timing problem. The box was horribly slow too, tarring and gzipping 600 mb took about 2 hours. The box has been on the internet without a firewall for approx 30 minutes, could it be r00ted that quick?
