The XMS3200LL designation of this particular package is suited to run on dual channel supported motherboards at DDR400 with a low latency setting of 2-3-2-6. The low latency setting refers to the CAS latency setting in your motherboard's BIOS. CAS stands for "Column Address Strobe" and is essentially a ratio generated between column access time and the clock cycle time of 2 cycles.
