described herein may contain design defects or errors known as errata which may cause the product to deviate from published

specifications. Current characterized errata are available on request.

Products Affected

The following Intel® Server and Workstation Systems based on Intel

C600 chipset:

 Intel

Server System P4000IP Family

 Intel

Server System R2000IP Family

 Intel

Workstation System P4000CR Family

Description

The I/O module (IOM) connector of above mentioned Intel

Server and Workstation Systems supports PCIe Gen1

speeds only. All Intel® I/O modules will run at PCIe Gen1 speeds in these systems even though the modules support

PCIe Gen2/3 speeds. Installing an Intel® I/O module may result in sub-optimal performance on these products.

Root Cause

This is a current I/O module Connector limitation.

Corrective Action / Resolution

Intel is working on feature improvements and may have a product refresh to support PCIe Gen2/3 speeds in the future.

Workarounds

If I/O performance is a concern in customer applications and they need higher I/O performance, please use PCIe form

factor add-in boards, rather than the Intel® I/O Modules. The Intel® I/O Module AXX4P1GBPWLIOM will not have this

performance drop due to the fact that PCIe Gen1 bandwidth can meet it’s transmission requirement.

Please contact your Intel Sales Representative if you require more specific information about this issue.
