QUOTE Hi there
Right guys myself and our technical guys have spent the entire weekend and this morning in discussions with Intel regarding the alarming amount of reports of Sandybridge CPU's dying and have been conducting our own testing as have Intel to find out what is a definite no no.
Sandybridge maximum safe voltages
Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!
Processor - Basically we recommend customers not to exceed 1.35v to play it safe, all our bundles are set at 1.3250v or lower, any competitors offering bundles above 4.6GHz you should be enquiring as to what voltage they are using as we believe anything over 1.38v will limit CPU lifespan and anything over 1.42v will likely kill the CPU or severely limit its lifespan.
Memory - Intel recommend 1.50v plus/minus 5% which means 1.60v is the ideal safe maximum, but we have found in our testing all 1.65v memory is fine. We have also found most new 1.65v like Corsair XMS3 will run at its rated timings with just 1.50-1.55v which is well within Intel specifications. So people upgrading to Sandybridge you can still use your old DDR3, but we do recommend you run it at 1.60v or less. We are shipping most of our bundles which feature Corsair XMS at 1.50v-1.55v at rated timings. We've also discussed with Asus and MSI regarding voltages for memory and they also confirm in their testing 1.65v caused no issues with reliability.
Base Clock - To put it simple if you value the life of your components, do not overclock using base clock!
PLL Voltage - Again do not exceed 1.9v!
These are just guidelines we recommend you follow, if you want to push more voltage through your CPU's then just be aware they could die on you. Your warranty is un-affected and we will honor any CPU's that die, we just won't ask questions as to how you killed them.
Not all CPU's are as fragile as others, we have experimented upto 1.50v Vcore and 1.70v memory and had zero issues with reliability, so it seems some of fine when pushing hard. Quoted from Gibbo at overclockers.co.uk forums. http://forums.overclockers.co.uk/showpost....492&postcount=1Hopefully this will be added to the OP since its very useful info for early SB aka LGA 1155 adopters.

QUOTE(zerorating @ Jan 16 2011, 02:10 AM) i think i already added this qoute above, however for oveclocker,it is a must to use the manual setting for overclocking, heard that u can oc really high even with 1.3v haha, just noticed right above. Need to get my eyes checked.  |

Yep, so all of us who have SB setups might probably have our mobos recalled as the issue is in the Intel PCH.(in P67s, H67s).
What a blunder by Intel. :/

Not all of us have money to spend constantly. I've been on LGA775 since 07, collected money and waited until this year to upgrade.
We can't make any assumption in regards to how long it will for the 'flaw' to arise. Intel has not stated the exact issue or failure rate.
It only affects SATA linked devices, HDs and Optical Drives mostly, so might as well play it safe and backup our data.

I just hope that the likes of ASUS, GB, MSI, Asrock etc can handle the recalling process smoothly. Don't want it to turn out like a 3 month RMA situation. :/

That's the risk with being an early adopter. I just wish they would be more specific about this problem, will this affect the health of the devices connected to the SATA ports, etc?

After reading again, we can assume that when Intel mentioned SATA Controller Degradation, we can interpret the possible outcome as data corruption.
Might have to consider buying a PCI-E SATA expansion card in the meantime. Sheesh.

QUOTE(Zax_imtiyaz @ Feb 1 2011, 11:51 AM) Cool guys... From what I've understand...that's not related with Sandy Bridge model that release in 9th Jan. It's effect the Intel Express 6 Chipset that have only been shipping since January 9 to the manufacturer.. Yes I know the official release of Sandy is 9th Jan, but in Malaysia the CPU and MOBO has been release earlier at shop (Dec '10)... so I think, the effect is only on the chipset that send to OEM after 9th Jan... just my 2cent Just think of it this way, it affects all chipsets released until the announcement was made. Because, the fault-free chipsets are currently being processed and is targeted to be delivered sometime around mid-February. This post has been edited by Zakov: Feb 1 2011, 12:26 PM |

QUOTE(gnne84 @ Feb 1 2011, 12:28 PM) hi all,
just wan to verify.
this cougar point issue just affected the motherboard chipset right?
the Sandy bridge processor still solid. only replacement for motherboard needed right? Yes and Yes. QUOTE(hilmiangah @ Feb 1 2011, 12:27 PM) i hope the fix the cannot overclock easily problem i hope they fix it quick There's nothing to fix there as it was intended that way. If you want to use Sandy Bridge graphics and maintain overclocking ability(via multiplier, BCLK is out of question), wait for the Z68 Chipset.

Intel losing a lot of money here, not to mention all the OEMs/Manufacturers that are pissed by this fiasco, not yet including the end-users of course.  Kind of reminds me of the TLP processor bug on AMD a few years back. |

It should be ok using 1&2 SATA ports on any Intel P67/h67 chipset as long as it is a SATA6gbps port. Its mentioned already that these ports are unaffected.

Anyone here with a P67 board that has switched SATA ports(from SATA3 to SATA6) ? Any feedback on HD performance? because people are reporting poor performance when using HDD on their SATA 6.0gbps ports. From my side, using a 500GB Caviar Green on SATA6, there seems to be no problems. |

So MSI are basically saying if we trust their products we can wait for replacement or if we don't or not willing to wait, we can demand an instant refund? sounds quite reasonable. QUOTE This MSI product you get swapped will have similar or better specs. I think I'm willing to wait. There's a chance we might get a Z68 board for replacement. Either way its going to B3 stepping from what I read at the official website This post has been edited by Zakov: Feb 4 2011, 12:22 PM |

Just for testing sake I put in an old SATA HD drive with redundant data to the SATA 3.0gbps port. I'm curious to see how it turns out after a month or so of normal usage. Bear in mind tho, Intel discovered the flaw by using proper testing conditions and stressed out the devices connected to the affected ports. |

I don't think it'll necessary affect MSI notebooks. Because we all know notebooks mostly only have two SATA ports(0 and 1) and its likely that the SB notebooks will use SATA 6gbps since it was one of the main points, besides the so-called change in CPU architecture of jumping from LGA1156 in the first place. Just my thoughts on this. |

QUOTE(OlgaC4 @ Feb 6 2011, 02:36 PM) Intel long time ago already discovered the flaw. Proof/Link please? Because I probably missed this out. I would also like to clarify my interpretation of your statement when you said 'a long time ago'. This post has been edited by Zakov: Feb 6 2011, 06:33 PM |

QUOTE(OlgaC4 @ Feb 7 2011, 11:52 AM) They got 77 problems. How they want to fix the processor that have been shiped out? By software??? If I were you I would start doing research before bashing out. How they want to fix the processor they have shipped out? Easy, they don't. There's no problem with the processor in the first place. The problem lies with the chipset., and the problem is isolated to the SATAII aka SATA300 aka SATA2 aka SATA 3.0gbps ports. Here. http://www.anandtech.com/show/4142/intel-d...t-begins-recallhttp://www.anandtech.com/show/4143/the-sou...-point-sata-bughttp://www.hardwarecanucks.com/news/cpu/in...-chipset-issuesTemporary solution is to use the SATA3 aka SATA 6.0gbps ports only for HDDs. Optical drives should be safe for use on the affected SATA2 ports. The real problem is for those who use RAID arrays or have a more than 2 HDDs/SSDs in their systems. As for the chipset problem, Intel are already working with manufacturers and OEMs to have the unsold boards recalled and the ones that are already sold to be either refunded or replaced once the new B3 stepping boards come out.

Yes, they're offering an exchange but it also depends on our local retailers. But since most shops provide at least a 1 year shop warranty they should assist us in the most convenient way possible.
This shouldn't be treated like an RMA case in my opinion, it should be like a 1-to-1 exchange.
