I'm pretty sure the E5410s (or any Harpertown/Woodcrest processor) in a standard configuration use fully buffered (FB-DIMM) RAM, as opposed to unbuffered. Super cool that Dell did some trickery in the CS24-SC (apparently CS means "custom server") to bypass that obnoxious requirement. EDIT: Apparently this family of servers use a bastardized chipset that doesn't require FB-DIMMs; nothing special on Dell's part.
