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.
