371049-B21 . Is a DDR Module. DDR Modules run from 266 to 400 MT/s (million transfers per second). This module has a total capacity of 2GB. The Bus Type is PC-2700. Its ECC (Error Correction Code) features prevent data corruption and system failure which is typically ideal for server machines. Has a data transfer rate of 333 Mhz.
ADATA XPG V1.0 memory products are made in conformation with JEDEC regulations and DDR3-1333 standards at CL value of 9-9-9-24 . Each XPG V1.0 memory chip is selected through a strict filtering process, complete with high-quality PCBs (Printed Circuit Board) and an aluminum heat sink that effectively lowers module temperature, proven to reach a maximum speed of 2133MHz to make complete use of the computer’s power.
483401-B21 . Is a DDR2 Module. DDR2 Modules run from 533 to 800 MT/s (million transfers per second). This module has a total capacity of 2GB. Has a Memory Bus Type of PC-5300. Uses ECC (Error Correcting Code), ideal when system failure must be avoided at all costs. Is also registered which makes it stable enough for server conditions. You can expect the data to transfer at a rate of 667 Mhz.
