Intel Discovers Bug in 6-Series Chipset: Our Analysis

In our Sandy Bridge review I pointed out that Intel was unfortunately very conservative in one area of the platform: its chipset. Although the 6-series chipset finally brought native 6Gbps SATA to Intel platforms it failed to fix issues with 23.976 fps video playback. Intel also failed to deliver a chipset that can support SNB's processor graphics as well as overclocking. Today, things just got even more disappointing.

Intel just announced that it has identified a bug in the 6-series chipset, specifically in its SATA controller. Intel states that "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.". I don't know the specifics of the bug yet, but Intel very rarely issues statements like this so it's likely quite serious. 

The fix requires new hardware, which means you will have to exchange your motherboard for a new one. Intel hasn't posted any instructions on how the recall will be handled other than to contact Intel via its support page or contact the manufacturer of your hardware directly. In speaking with motherboard manufacturers it seems they are as surprised by this as I am. 

Intel will begin shipping the fixed version of the chipset in late February.  The recall will reduce Intel's revenue by around $300 million and cost around $700 million to completely repair and replace affected systems.

Read on for more information on the nature of the bug and what it means for current and future SNB owners.
