Processor Support

The Compute Module supports the following processors:

One or two Intel

Xeon

Processor 5500 series with 4.8 GT/s, 5.86 GT/s or 6.4 GT/s

Intel

QPI link interface and Thermal Design Power (TDP) up to 95 W.

One or two Intel

Xeon

Processor 5600 series with a 6.4 GT/s Intel

QPI link interface

and Thermal Design Power (TDP) up to 95 W.

Previous generations of the Intel

Xeon

processors are not supported on the compute module.

3.1.1.1

Processor Population Rules

Note: Although the Compute Module does support dual-processor configurations consisting of
different processors that meet the defined criteria below, Intel does not perform validation
testing of this configuation. For optimal performance in dual-processor configurations, Intel
recommends that identical processors be installed.

When using a single processor configuration, the processor must be installed into the processor
socket labeled CPU1. A terminator is not required in the second processor socket when using a
single processor configuration.

When two processors are installed, the following population rules apply:

Both processors must be of the same processor family.

Both processors must have the same front-side bus speed.

Both processors must have the same cache size.

Processors with different speeds can be mixed in a system, given the prior rules are met.
If this condition is detected, all processor speeds are set to the lowest common
denominator (highest common speed) and an error is reported.

Processor stepping within a common processor family can be mixed as long as it is
listed in the processor specification updates published by Intel Corporation.

3.1.2

Mixed Processor Configuration

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

Compute Module MFS5520VI. Errors fall into one of the following categories:

Fatal: If the compute module can boot, it pauses at a blank screen with the text
“Unrecoverable fatal error found. System will not boot until the error is resolved”
and “Press <F2> to enter setup”, regardless of whether the “Post Error Pause” setup
option is enabled or disabled. When the operator presses the F2 key on the keyboard,
the error message is displayed on the Error Manager screen, and an error is logged with
the error code. The compute module cannot boot unless the error is resolved. The user
needs to replace the faulty part and restart the system.

Major: If the “Post Error Pause” setup option is enabled, the compute module goes
directly to the Error Manager to display the error and log the error code. Otherwise, the
compute module continues to boot and no prompt is given for the error, although the
error code is logged to the Error Manager.
