DDR memory types are determined by two factors: speed and rank. LH500 supports DDR 333/266 speed in both single/dual rank. The rank of your memory could impact the effectiveness of the motherboard. Table 1 indicates the setup that LH500 has been tested on.
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.
The first row reads: if you use 1 pair of DDR of type single rank, install in 1st_Pair slots.
