6-series chipset fiasco FAQ from the Maximum PC Staff:

Q: What’s the problem?

A: Some of the SATA ports that come off of the Intel 6-series PCH or Peripheral Control Hub may begin producing errors over time. The problem isn’t immediate, but can happen over time. That means that a port that is working fine today, may start to generate data errors. This will affect performance and the port may simply stop working over time. Increased thermals and voltage on the ports may also contribute to the port failing sooner. The only good news is that ports 0/1 are unaffected by the bug.

Q: Is it the actual Sandy Bridge CPU that’s bad?

A: No. Intel said the problem is not the CPU, but the chipset. However, one thing that we don’t know yet is why Intel said it should only affect those with Core i5 and Core i7 processors. That implies that 6-series with Core i3 is fine. We are still waiting for more details.

Q: How did Intel find it?

A: The company said it came to light last week when customers, either OEMs or board vendors, brought it to Intel's attention. Intel labs was able to verify the problem and the decision was made yesterday to halt shipment of the parts.

Q: How is Intel going to fix this?

A: The company is correcting the problem in silicon and is in process of fabbing new chipsets without the problem. The bad news: boards and systems with the fixed chip will likely not be available for at least a month.

Q: Is the chipset in my motherboard or notebook impacted?

A: Intel didn’t get into specifics this morning but the short answer is probably yes. However, one aspect of the problem is that it may only manifest itself on occasion. That is, some boards may exhibit the issue, while others will not. The problem seems to be unpredictable and only after three years, Intel projected 5 percent failures but said heavier use could accelerate the issue.

Q: So my notebook is bad?

The good news is that most notebooks only have two SATA ports which happen to run on ports 0/1. But as we said, that’s most notebooks. Some notebooks that use more than ports 0/1 or that used the others ports would be affected.

Q: Can this be fixed with a new BIOS or some other firmware update?

A: No. The problem is a hardware issue that cannot be fixed without replacing the affected chipset on the system. Since you can’t simply replace a chipset in a motherboard, the only way to fix it would be to complete replace the motherboard.

Q: So which ports are bad on my motherboard again?

A: Intel’s PCH supports six ports. Of those, ports 0/1 are unaffected. These are also the SATA 6Gb/s ports. The remaining four SATA 3Gb/s ports may or may not exhibit the breakdown over time. Many motherboards also support additional ports using third-party controllers such as Marvell’s SATA 6Gb/s. These would be unaffected. eSATA ports on the rear of the motherboard should also be unaffected as those mostly use third-party controllers from Jmicron.

Q: What is Intel going to do to make me whole?

A: That’s not completely clear at this point. Intel said this morning that: “Intel stands behind its products and is committed to product quality. For computer makers and other Intel customers that have bought potentially affected chipsets or systems, Intel will work with its OEM partners to accept the return of the affected chipsets, and plans to support modifications or replacements needed on motherboards or systems.” However, motherboard and PC vendors we spoke with this morning had no guidance on the topic yet. Stay tuned to this FAQ to find out what vendors will be doing.

Q: Will my motherboard vendor replace my motherboard?

A: That’s not known. As of this morning, board vendors had stopped shipping 6-series boards. They were being updated by Intel on details of the problem. Whether board vendors would replace the boards or not is not known yet so stay tuned. On pure speculation though, it’s quite possible that vendors may offer to replace the board with one with the newer spin of the chipset once they are available. They may also opt to let the consumer extend the warranty instead of replacing the board. Again, this is pure speculation, but we know from previous experience that you shouldn’t always expect vendors to simply replace it.

Q: My system has the chipset, will my OEM replace the motherboard?

A: That’s not clear. We’ve talked to numerous OEMs who were also in the dark about the issue. No matter what, we suspect the solutions won’t be pretty. Even if the OEMs agree to replace the boards on Intel’s dime, there’s still down time and dealing with shipping a system back and forth and the risk of data loss. It’s possible, and we are just speculating here, that the fix will be an increased warranty to say, three years. If the ports fail within that period, the OEM will repair it. If it doesn’t fail, then maybe it wasn’t that bad in the first place. We are speculating here because in previous bad chip situations, an outright replacement is usually something vendors are resistant to doing.

Q: This sounds like a class-action lawsuit in the making.

A: How Intel will make people whole isn’t known yet, but yes, we suspect that someone unhappy with how this turns out will certainly file suit.

Q: Is it OK to practice schadenfreude now and prance about why I’m so lucky I built an AMD system or X58 box?

A: Yes. The full schadenfreude effect is in place. Please feel free to dance about forums and post about how it **s to not be you. Just remember that schadenfreude (deriving pleasure from the misfortune of others) often leads to Karmic justice.

Q: Will Intel be creating a new chipset model with the fix so we can know when it's safe to buy a motherboard for Sandy Bridge?

A: Intel will not create a new chipset model, and a re-spin of the silicon will correct the issue, the company said. OEM's have privately told us that the B3 spin of the 6-series chipset is not impacted, but we have not been able to confirm that with Intel. As far as buying a system, notebook or board with the issue; the vast majority of stores and OEMs have already halted shipment of Sandy Bridge-based systems. Systems and boards will likely not start shipping until the fix is in.

Q: Is this the first time Intel has had a chipset problem of this proportion?

A: Actually no. Although the 6-series chipset screwup may be the worst in dollar amount, Intel actually blew it on the “Cape Cod” CC820 chipset back in 2000. That Pentium III chipset was designed to sidestep resistance to Direct RDRAM. The CC820 took the “Vancouver” 820 chipset and integrated a Memory Translator Hub so that the RDRAM-only chipset would work with SDRAM. Unfortunately, bugs in the chipset forced Intel to recall chipsets and boards based on the CC820. The final tune for that mistake was $253 million which adjusted for inflation would be roughly $312 million.

Q: I have a 6-series chipset in my system or notebook, is it safe to use?

A: Intel and numerous OEMs say that since the problem should occur over several years and only to a fairly small percentage of systems and notebooks, the risk of data loss is nil. If a port goes bad, you just move it to a port that works and the data will be there, Intel says.

看不懂，正准备年后升级了，看来要等明年再升级了
