Chipset circuit design issue identified

Update February 7, 2011

Intel has worked closely with computer makers around the world, and together have developed a solution that allows computer manufacturers to resume shipments of systems. Both Intel and its customers are focused on delivering the highest quality PC systems based on 2nd generation Intel® Core™ processors. Intel is resuming shipments of the Intel® 6 Series Chipset for use only in PC system configurations that are NOT impacted by the design issue.

On January 31, 2011, Intel disclosed a design issue with a support chip, Intel® 6 Series Express Chipset, indicating that under normal operation the chipset could experience an issue with integrated SATA ports 2–5 that may result in these SATA ports experiencing a functional issue over time. Systems with only integrated SATA ports 0 and 1 enabled are not susceptible to this issue.

After extensive discussions with computer manufacturers about this topic and specific requests from computer manufacturers, Intel is resuming shipments of the Intel® 6 Series Express Chipset for use only in PC system configurations that are not impacted by the design issue. Only computer makers who have committed to shipping the Intel® 6 Series Express Chipset in PC system configurations that are not impacted by the design issue will be receiving these shipments.

In parallel, Intel has started manufacturing on a new version of this support chip. As of February 14th 2011, Intel has already begun shipments of the new Intel® 6 Series Express Chipsets and computer manufacturers have begun building and shipping systems.

If you have an Intel® 6 Series Express Chipset based system and you are experiencing an issue with SATA devices, such as hard disk drives, solid-state drives, DVD players, or Blue-ray* players, on ports 2–5, please contact your point of purchase to determine next steps.

To determine if you have one of the impacted Intel® 6 Series chipsets in your system, follow these steps.

Intel is requesting that distributors accept returns from their customers opened or unopened (even beyond 30 days) if affected by this issue.

Are previous generation Intel® Series Express Chipsets affected?
No, this issue only impacts the Intel® 6 Series Express Chipsets systems with devices using SATA ports 2-5. Intel® 6 Series Express Chipset based systems with only SATA ports 0 and 1 enabled are not susceptible to this issue.

I have a system affected by this issue. What should I do next?
There is no imminent failure, and your product should be replaced. Go to your place of purchase for more information in the coming days. Some retailers are continuing to gather details about the situation before responding to customer inquiries.

What is Intel doing about this issue?
Intel has identified the cause of the issue and is taking the following actions:

  • We are working with manufacturers who used this component to determine appropriate actions for systems that have been built and shipped to customers. These actions will be available from your place of purchase or system manufacturer in the coming weeks. Intel recommends that the end user contact the entity where the system was purchased for diagnosis and possible return.
  • Intel is resuming shipments of the Intel® 6 Series Chipset for use only in PC system configurations that are not impacted by the design issue.

When can I order production units of Intel®-branded desktop boards that use the B3 stepping of Intel® 6 Series Express Chipsets?
Requests can be made through the normal order process now. Production units of Intel®-branded desktop boards based on B3 Stepping of Intel® 6 Series Express Chipsets will start shipping by February 25, 2011.

If my place of purchase does not extend the 30-day warranty, what do I do then?
Please be patient. We are currently working out the details of our replacement program with your place of purchase, and they may need some time before they have details available for you. If your 30-day warranty expires as you are waiting for the details to be worked out, please be confident that Intel will stand behind its products and your affected product will be replaced.

Is there a way I can tell an Intel® 6 Series Express Chipset B2 stepping from a B3 stepping?
The most accurate way to identify a B2 stepping from a B3 stepping is to read the S-Spec markings on the top of the Chipset, and either:

Note Tools/applications designed to report the Intel® 6 Series Chipset Stepping Revision may not properly report stepping information due to system specific BIOS configurations.
