A flaw in the silicon at the metal level for H/P-67(Cougar Point) causes SATAII links to degrade and eventually fail all together. A major recall is in effect http://www.tomshardware.com/news/cougar-point-sandy-bridge-sata-error,12108.html

Im guessing if you have a board already you should be able to RMA once the new silicon is out.

Most major retailers are aware of the issue and are removing their stocks of boards but there will be flawed boards in the channels for a while I'm sure.

If you are thinking about upgrading to Sandy Bridge and have SATAII devices, I would wait a few weeks/months.

**Update** http://www.tomshardware.com/news/Cougar-Point-Sandy-Bridge-B3-Stepping-product-change-notification-chipsets,12184.html
Intel have announced they plan to start shipping revised cougar point this week starting Feb 14, B3 steppings of H/P67 will start shipping to OEMS sooner than expected. There should hopefully be new boards in the channels by mid-late march hopefully at best guess. I would still be careful of buying off the shelf systems for a while, as they resumed shipping B2 steppings for applications that aren't using the broken features(certain laptops/desktops that are exclusively SATA III).

I came very close to pulling the trigger on a kit to build a Sandy Bridge set-up; glad i waited a couple of days til the news came out. Debating whether to wait, or just build an 1156 based system; Tom's rated the i5-760 highly prior to Sandy Bridge coming out.

They are already shipping new chips with this fixed I read about this last week. Apparently it only affects the second channel of SATA so if you only need 1 or 2 drives your fine.

Source ? Also how did you read about it last week when Intel made the annoucement on monday ? Major OEM's/Partners were unaware as late as tuesday that there was a flaw. There was rumors in the hardware forums but most people chalked it up to early adoption/driver problems.


Intel themselves have said it will take at least untill early march or april at the latest to start shiping revised chipsets. If the problem was minor, I doubt they would be spending over $700 million to replace it. OEMS are even offering refunds at this point which is unusual.
It affects all of the SATA II links, SATA III is unaffected, some of the current "fixed" mobo's are exclusively SATAIII. Also Z-68 is unaffected, however the vast majority of Sandy Bridge Mobos are going to be H/P67 based.

"The company expects to begin delivering the updated version of the chipset to customers in late February and expects full volume recovery in April. Intel stands behind its products and is committed to product quality."

"Manufacturers told us that revised motherboards and notebooks based are unlikely to appear until at least April of this year, and Intel probably won't be supplying new chipset revisions until early to mid-March. However, replacements are unclear as manufacturers are informing us that details need to be worked out with Intel on how customers will be handled."

"OEMs and motherboard manufacturers are going to be talking to Intel over the next week to figure out the next steps. Intel plans to deliver fixed silicon to its partners at the end of February, however it’ll still take time for the motherboard makers to turn those chips into products. I wouldn’t expect replacements until March at the earliest."

I would be looking at a 1366 based solution,the prices have come way down on x58. It is considered the high end solution untill Ivy Bridge comes later this year, and you will still have the option of going hex core in the future(unlike 1156). An i7 950 at 3.8 - 4.0ghz (easy overclock) is going to be more than enough for the near future. However for the long term both of those sockets are pretty much dead. (It's still up in the air if new processors will come out on 1366)

Even though the i5/7 2xxx series has an awesome IPC right now(15-30% more than similar clocked i5 7xx and i7 8xx and 9xx), making it very attractive. I would be leary of investing in something that has a proven flaw in it at the moment(the processors are great the mobo's not so much at this point). If you can wait until around April it should be hopefully sorted out by then.

When I first read about it I started here: http://gizmodo.com/5747876/intel-kills-sandy-bridge-chipset-shipments-after-admitting-design-flaw

From there I don't remember all the places I went and read. Also sorry it wasn't last week it was Monday when I read it, been a long week so it felt like it was last week.

It's all good, just wondering if you have better sources :supergrin:
