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
DDR3
• 2gB and 4gB DDR3 ThinkServer Memory support Advanced ECC and Memory
800-1600Mbps
Mirroring. These features are critical in having the right virtualization solution
1.5V +/- 0.075V
• Dual processor ThinkServer systems that support Intel's 5500 Series processors
are designed with dedicated memory banks for each processor. When adding
8
memory to these systems, each processor will gain immediate performance gain

some unique benefits provided for DDR3 to take advantage of:
• Integrated Memory controller
– Increases the memory bandwidth without compromising performance
• Intel
– Point-to-point high-speed links between the processor and distributed shared
