SATA Ports 2-5 Issue

Problem:

Due to a circuit design issue on Intel 6 Series Chipset and Intel C200 Series Chipset,

electrical lifetime wear out may affect clock distribution for SATA ports 2-5. This may

manifest itself as a functional issue on SATA ports 2-5 over time.

• The electrical lifetime wear out may result in device oxide degradation which over

time can cause drain to gate leakage current.

• This issue has time, temperature and voltage sensitivities.

Implication: The increased leakage current may result in an unstable clock and potentially functional

issues on SATA ports 2-5 in the form of receive errors, transmit errors, and

unrecognized drives.

• Data saved or stored prior to functional issues on a SATA device will be retrievable

if connected to a working SATA port.

• SATA ports 0-1 are not affected by this design issue as they have separate clock

generation circuitry.

Workaround: Intel has worked with board and system manufacturers to identify and implement

solutions for affected systems.

• Use only SATA ports 0-1.

• Use an add-in PCIe SATA bridge solution.

Status:

Fixed. For steppings affected, see the Summary Table of Changes.

• This issue has been resolved with a silicon stepping for all Intel 6 Series Chipset

and Intel C200 Series Chipset incorporating a minor metal layer change.

• The fix does not impact the designed functionality and electrical specifications of

the Intel 6 Series Chipset and Intel C200 Series Chipset.

Intel® ME Clock Throttling Failure Causes Hang

Problem:

When the Intel® Management Engine (Intel® ME) firmware sets the internal clock

frequency, the Intel ME clock may stop toggling, potentially causing the Intel®

Management Engine Interface to become unresponsive.

Implication: Parts that exhibit this issue may hang during POST.

Note:

No functional failures have been seen due to this issue.

Workaround: An Intel® ME Firmware code change has been identified and may be implemented as a

workaround for this erratum.

Status:

No Plan to Fix.
