User manual

They are running on dual channel memory bus and two-way interleaved memory banks. Therefore, the
memories must be INSTALLED IN MEMORY DIMM 1 AND 2, OR 3 AND 4. Be sure that every
memory module is of the same speed, size and rank.
DDR memory types are determined by two factors: speed and rank. SW310 supports DDR 400/333/266
speed in both single/dual rank. The rank of your memory could impact the effectiveness of the
motherboard. Besides DDR400 is supported by Opteron CPU rev. C0 and later.
The number of memory chips and how they are stacked on a memory
module do not indicate the rank of that memory module. The only
way to determine the rank of a memory module is to contact the
memory manufacturer for its specification.
