HEadING TO GREENER PaSTuRES

Introducing new DDR3 ThinkServer memory for ThinkServer systems with the

Intel

Xeon

5500 Series processors. ThinkServer DDR3 memory is the next

generation of SDRAM memory that enables high I/O data transfer rates through

increased peak bandwidth (1333MHz) and reduces power consumption over

DDR2 technology. Faster data transfer rates mean higher performance and with

DDR3 memory this is achieved without straining the system's power needs.

fEaTuRE adVaNCEd ECC TECHNOLOGy

• Advanced ECC works similar to RAID for disk subsystems. If a memory failure

occurs, the data is immediately recovered by recalculating the data from the

checksum information

• This allows the system to mask not only the single bit errors (standard ECC) but

also 2, 3 and 4-bit errors (Advanced ECC has 99.94% reliability)

•

DDR3 also uses more internal banks to reduce access latency and increases

performance

• 2gB and 4gB DDR3 ThinkServer Memory support Advanced ECC and Memory

800-1600Mbps

Mirroring. These features are critical in having the right virtualization solution

• Dual processor ThinkServer systems that support Intel's 5500 Series processors

are designed with dedicated memory banks for each processor. When adding

memory to these systems, each processor will gain immediate performance gain
