Intel Sandy Bridge Chipset Fault – Affecting SATA Ports – Shipments Stopped


A problem requiring a “silicon fix” is bad news in the chipset business, and sadly that’s what Intel is announcing. Its new Intel 6 Series chipset, Cougar point, has been found to have a flaw, something to do with the SATA controller. Intel is indicating that the ports can “degrade over time,” leading to poor i/o performance down the road. All shipments have been stopped and a fix has been implemented for new deliveries, but it sounds like recalls will be starting soon for those with this ticking time bomb silicon within. It isn’t a critical problem right now, though, so if you own a Sandy Bridge Core i5 or Core i7 system keep computing with confidence while looking for a recall notice, but it is bad news for Intel’s bottom line: the company is advising a $300 million hit to revenue.

Update: chat log with an Intel customer service representative indicating that this recall only affects “some desktop boards based on Intel P67 chipset,” that the H67 chipset boards appear to not be affected, but that the company doesn’t have a comprehensive list yet. We’ve certainly seen cases where CSRs don’t have all the info in this sort of situation, but still we’d advise waiting a bit before tearing your new mobo out and bringing it back to the store.



Intel raised quite a few eyebrows yesterday by disclosing that its Cougar Point chipsets suffer from an incurable design issue that would potentially degrade Serial ATA transfers over time. AnandTech has gone to the trouble of getting in touch with Intel to seek more information and the problem, as it turns out, is a single transistor that’s prone to a higher current leakage than tolerable. This can not only diminish performance over the 3Gbps SATA ports, it can actually make them fail altogether. There is more comforting news, however, in that the pair of 6Gbps SATA ports on the chipset are untroubled by this ailment, so devices and users that never plug into the 3Gbps connections can just carry on as if nothing’s ever happened. For everyone else, a repair and replacement service is taking place now, with Intel’s budget for dealing with this problem said to be a generous $700 million.
