Intel Resumes Chipset Shipments for PCs Not Affected by Flaw

Intel has resumed shipments of a chipset with a flawed design, but only for PCs that are not affected by the issue. Intel also says it will start shipping new chipsets in mid-February.

A week after announcing a design flaw in a chipset tied to its "Sandy Bridge" processor platform, Intel is resuming shipments of the chipset to PC makers whose PC configurations are not affected by the problem.

In a statement released Feb. 7, Intel officials said their decision comes after a week of meeting with OEMs and following specific requests from some PC makers. Intel did not specify which systems makers made the request.

"Only computer makers who have committed to shipping the Intel 6 Series Chipset in PC system configurations that are not impacted by the design issue will be receiving these shipments," Intel officials said in a statement.

On Jan. 31, Intel executives announced that they had discovered a design flaw in the chipset the week before, and had subsequently found a fix for the problem and were beginning to manufacture new chipsets with the problem corrected. They also had stopped shipments of the problem chipsets, about 8 million of which had been shipped and some of which had been put into systems that had been bought by end-users.

As part of the update announced Feb. 7, Intel executives also said they have started manufacturing the new chipsets, which now should start shipping in mid-February. Last week, they had said shipments would start in late February.

Intel executives said they had made the decision to stop shipments of the flawed chipset on Jan. 30, and began working with PC makers the next day. They estimated that the issue could cost Intel $1 billion in lost revenue and related expenses.

The design flaw affected four of six SATA (Serial ATA) ports in the chipset, which over time could cause problems in the performance of such PC peripherals as the SATA hard-disk drive or optical drive. Endpoint Technology Associates analyst Roger Kay noted that the problem affected the four 3G bps SATA ports, and not the two 6G bps ports that are most often used by consumers, so many end users will not have any issues down the road.

Intel executives estimated that the problem could affect 5 to 15 percent of the chipsets made, and stressed that the issue was with the chipset and not the Sandy Bridge processors. The second-generation core processors were rolled out at the Consumer Electronics Show in early January, and key among their features is discrete-level graphics capabilities integrated with the CPU onto a single piece of silicon.

After Intel's Jan. 31 announcement, PC makers began working with the chip giant to figure out how to address the problem. A host of OEMs, including Hewlett-Packard, Dell, Acer and Samsung Electronics, said they were offering customers who had bought systems with the flawed chipset the chance to return the PCs for repair or replacement.

"Acer has already stopped shipping the products impacted by this issue and has instituted a program to assist customers who purchased affected units," a company spokesperson said in a statement released Feb. 4. "At the same time, Acer is working in close collaboration with Intel to coordinate the next steps."

Analysts said that in the long term, the chipset problem would have little impact on Intel beyond the $1 billion financial hit but that the PC makers would bear the brunt of dealing with customers. They also said the problem could give Intel rival Advanced Micro Devices a brief boost in the tight competition around systems on a chip.
