Features Summary

Intel

Xeon

Processor C5500/C3500 Series

Datasheet, Volume 1 February 2010

28 Order Number: 323103-001

Note:

1. All processors are Intel

Xeon

processors except for processor number P1053. Processor number

P1053 is the Intel

Celeron

processor. The P1053 does not support memory RAS features, i.e.,

scrubbing (demand and patrol), mirroring, lockset, and SDDC. The sections of the Datasheet describing

these features DO NOT apply to he P1053.

1.4 Interfaces

1.4.1 Intel

QuickPath Interconnect (Intel

QPI)

The Intel

QuickPath Interconnect (Intel

QPI) interconnets two processors for SKUs

that support DP configurations. Intel

QPI is a cache-coherent links-based

interconnect, which is an Intel proprietary specification for links-based processor and

chipset components.

Intel

QPI on the Intel

Xeon

processor C5500/C3500 series supports the following

features:

• 64-byte cache lines

• SKU dependent Link transfer rates: 4.8 and 5.87 GT/s

• L0, L0S, and L1 power states

• 40-bit Physical Addressing

•Intel

QPI Route-Through to allow DP systems to seamlessly access each other’s

resources.

1.4.2 System Memory Support

• SKUs supporting two or three channels of DDR3 memory:

— Registered, ECC, up to three DIMMs per channel (three DIMMS only supported

at 800 MT/s), X4 or X8 with 1-Gb, 2-Gb, or 4-Gb DRAM technology.

— Unbuffered, ECC or not, up to two DIMMs per channel, X8 or X16 with 512 Mb

or 1-Gb or 2-Gb or 4-Gb DRAM technology.

— Max memory supported 192 GB (with 2-Gb DDR3 devices).

• Data burst length of 4 for lockstep mode and 8 for other memory operation modes.

• Memory DDR3 data transfer rates of 800, 1066, and 1333 MT/s

•64-bit wide channels

• DDR3 I/O Voltage of 1.5 V

• Memory operating modes:
