Intel® Server Board S5500WB TPS

Functional Architecture

Revision 1.9

Intel order number E53971-008

3.3 Processor Subsystem

The Intel

5500 series and the next generation Intel

5600 series processors support the

following key technologies:

 Intel

Integrated Memory Controller

 Point-to-point link interface based on the Intel

QuickPath Interconnect (Intel

QPI),

which was formerly known as the Common System Interface (CSI).

The Intel

5500 series processor is a multi-core processor based on the 45 nm process

technology. Processor features vary by SKU and include up to two Intel

QPI point-to-point links

capable of up to 6.4 GT/s, up to 8 MB of shared cache, and an integrated memory controller.

The Intel

5600 series processor is the next generation of multi-core processors based on the

32 nm process technology. Processor features vary by SKU and include up to 6 cores and up to
12 MB of shared cache.

3.3.1

Processor Support

The Intel

Server Board S5500WB supports the following processors:

 One or two Intel

5500 series or 5600 series processor(s) in FC-LGA 1366 socket B

package with 4.8 GT/s, 5.86 GT/s, or 6.4 GT/s Intel

QPI.

 Up to 95 W Thermal Design Power (TDP).
 Supports Low Voltage (LV) processors.

3.3.2

Processor Population Rules

For optimum performance, when two processors are installed, both must be the identical
revision and have the same core voltage and Intel

QPI/core speed. When only one processor

is installed, it must be in the socket labeled CPU1. The other socket must be empty. You must
populate processors in sequential order. Therefore, you must populate processor socket 1
(CPU1) before processor socket 2 (CPU2).

When a single processor is installed, no terminator is required in the second processor socket.

3.3.2.1

Mixed Processor Configurations

The following table describes mixed processor conditions and recommended actions for all
Intel

server boards and systems that use the Intel

5500 Chipset. The errors fall into one of the

following two categories:

 Fatal: If the system can boot, it goes directly to the error manager, regardless of

whether the Post Error Pause setup option is enabled or disabled.

 Major: If the Post Error Pause setup option is enabled, the system goes directly to

the error manager. Otherwise, the system continues to boot and no prompt is given
for the error. The error is logged to the error manager.
