SANTA CLARA, Calif., Jan. 31, 2011 - As part of ongoing quality assurance, Intel Corporation has discovered a design issue in a recently released support chip, the Intel® 6 Series, code-named Cougar Point, and has implemented a silicon fix. In some cases, the Serial-ATA (SATA) ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives. The chipset is utilized in PCs with Intel's latest Second Generation Intel Core processors, code-named Sandy Bridge. Intel has stopped shipment of the affected support chip from its factories. Intel has corrected the design issue, and has begun manufacturing a new version of the support chip which will resolve the issue. The Sandy Bridge microprocessor is unaffected and no other products are affected by this issue.
 
The company expects to begin delivering the updated version of the chipset to customers in late February and expects full volume recovery in April.

I just got off a conference call with Intel and it looks like they got a  mess on their hands right now. Intel had a design oversight with one of  the metal layers of their 6 series chipset, so they need a re-spin of  the silicon to fix the issue. This issue is on all 'Cougar Town' 6  series chipsets and Intel said that slightly less than 8 million of  these chipsets have already been made. All of those chipsets have  Serial-ATA (SATA) ports within the chipsets that may degrade over time,  potentially impacting the performance or functionality of SATA-linked  devices such as hard disk drives and DVD-drives. Intel said that the  issue is only one four of the chipsets six SATA ports.  The SATA III  6Gbps ports are not impacted by this issue. Intel went on to say that  not one consumer board has been returned with this issue, but it's an  issue that arises with time. Internal Intel use conditions right now  project 5-6% failure rates for notebooks over a 3 year life for a  machine. It appears that the more voltage and higher temperatures the PC  is run at will only increase the chances of failure. What happens when  it fails?  It looks like you'll get bit errors on the SATA link and have  drives no longer showing up on the platform.  It sounds like no data  will be lost though and that the drive can be placed on another system  for data recovery if your chipset should fail.  Intel expects to have  new silicon to be rolling off the fab lines in February and then have  the issue resolved in April 2011. We have contact ASUS, MSI, Gigabyte  and ECS, but none of the companies responded.  MSI replied that we were  the first to bring the issue to their attention.  We looked at Newegg  and they are still selling Intel 6 series boards.

It estimated the  total cost to repair and replace the chip at about $700 million. The  issue on the new chipset means that the Serial-ATA (SATA) ports within  the chipsets may degrade over time, potentially impacting the  performance or functionality of SATA-linked devices such as hard disk  drives and DVD-drives.

If you already have a board hold  tight as Gigabyte is figuring out what to do right now. Gigabyte is  planning on doing some sort of RMA for users that have one of these new  boards. If we had to guess those of you that have one of these boards  should sit tight a month or two until Intel gets production ramped up on  the fixed 6-series chipset. Gigabyte USA said they should have some  more news on the subject later today at 3pm PST.

For the 6-series boards, we have stopped shipping boards out from our warehouse. All our sales has informed all our  channels/resellers/distributors to stop selling the 6-series boards. The  management is discussing with our HQ to find out more detailed  solutions and will keep you updated later today.
