Q: Q: What brands and types of memory does the 400SC support?
A: It seems that the only problematic RAM is low-latency, ultra-performance PC3200 RAM, which is set to run at too high a speed for Dell's conservative BIOS, which in turn clocks the RAM down to PC2700 speeds. Also, some high-performance, overclocker-marketed RAM has been known to be programmed with incorrect SPD information, which can also cause the RAM to run at lower-than-advertised speeds. As always, make sure the RAM you buy has a good warranty in the case it doesn't perform as desired. The following RAM is listed here only because it's been reported to me as working. This list is by no means complete. There are likely many more unlisted types of RAM that work fine. The following has been tested:
