Citat:

SANTA CLARA, Calif., Jan. 31, 2011 - As part of ongoing quality assurance, Intel Corporation has discovered a design issue in a recently released support chip, the Intel® 6 Series, code-named Cougar Point, and has implemented a silicon fix. In some cases, the Serial-ATA (SATA) ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives. The chipset is utilized in PCs with Intel's latest Second Generation Intel Core processors, code-named Sandy Bridge. Intel has stopped shipment of the affected support chip from its factories. Intel has corrected the design issue, and has begun manufacturing a new version of the support chip which will resolve the issue. The Sandy Bridge microprocessor is unaffected and no other products are affected by this issue.
 
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. 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. The systems with the affected support chips have only been shipping since January 9th and the company believes that relatively few consumers are impacted by this issue. The only systems sold to an end customer potentially impacted are Second Generation Core i5 and Core i7 quad core based systems. Intel believes that consumers can continue to use their systems with confidence, while working with their computer manufacturer for a permanent solution. For further information consumers should contact Intel at www.intel.com on the support page or contact their OEM manufacturer.


Way to go Intel !!! Za sada nisam primetio nikakav problem sa SATA kontrolerom, sve radi kako valja, garancija je tri godine na plocu tako da nisam nesto zabrinut :)

Anand je kao i uvek pokusao da se informise sto bolje :)

Za sada mi SMART ne prikazuje nista, jedino sto su mi performanse nesto losije nego na on-line benchmark-ovima i vidim cudne drop-ove u HDTune-u ali ne verujem da je to to...

Znate kako je kada ste early adopter :-)))

Salu na stranu, iako naravnno nije dobro sto je doslo do buga - reakcija Intela je apsolutno za svaku pohvalu i predstavlja ostar kontrast u poredjenju sa 90-tim. Sta je izazvalo ovakvu promenu u "karakteru" Intela je interesantno pitanje - mozda sama velicina trzista danas a mozda i veci strah od kazni posle svega sto se desavalo u proteklih par godina.

Inace, kako se procesi izrade usavrsavaju - bice interesantno pratiti da li ce se broj "gremlina" povecavati... Pogotovu kada se krene ispod 22nm :-)

Inace SB laptopovi bas kasne... mada sto se mene tice, ja cekam SB Vaio Z :-) Interesantno, ovog puta je i Sony odlucio da saceka sto se premium modela tice, lansirali su neki SA model koji koristi SB ali koji je prilicno "ispod" Z-a sto se form-factora i feature-a tice... ko ce ga znati sta se sve krije u SB-u :)

Cak se pojavljuju glasine da i CPU pati od nekog design flaw-a mada to jos uvek nije potvrdjeno (moguce da je patka).

Ma u principu boli me uvo, hteo sam da odradim upgrade jos prosle godine pa kada sam cuo sta sve SB nudi i kakva su arhitekturalna poboljsanja resio sam da sacekam i uzmem ga kad se pojavi. Za sada qliram, dok se ne pojavi prvi UDMA CRC error, onda hdd i odd prebacujem na 6Gbps portove (imam ih 2 komada) i cekam April mesec da reklamiram plocu ako bude bilo ikakvih problema.

Gigabyte i MSI su stopirali prodaju ploca baziranih na P67/H67 chipsetu dok se AsRock i Asus jos uvek mogu naci na newegg-u. Ukupno 9 ploca i dalje u prodaji, ne znam da li ce i njih povuci.

Ovo ce kostati Intel poprilicno mada ovo im se nije desavalo jos od 93'ce i greske prilikom floating point operacija, AMD je imao TLB bug na Phenom I... Jos kontam upravo da je Tock pravo vreme za upgrade, Tick tj smanjivanje proizvodnog procesa je uvek rizicno iako je arhitektura matora - ali jbg, ovo nije CPU vec PCH problem.

Ako problem bude resavan prema najavama, tj free replacement za noviju reviziju ploce - onda je reakcija stvarno za svaku pohvalu i pored fail-a.

Citat:

The problem in the chipset was traced back to a transistor in the 3Gbps PLL clocking tree. The aforementioned transistor has a very thin gate oxide, which allows you to turn it on with a very low voltage. Unfortunately in this case Intel biased the transistor with too high of a voltage, resulting in higher than expected leakage current. Depending on the physical characteristics of the transistor the leakage current here can increase over time which can ultimately result in this failure on the 3Gbps ports. The fact that the 3Gbps and 6Gbps circuits have their own independent clocking trees is what ensures that this problem is limited to only ports 2 - 5 off the controller.


E a kakav tajming imaju sa objavljivanjem ove vesti, taman za kinesku novu godinu... :) Ono, mogu da zamislim kakav haos sad vlada, sad se ceo kineski tech menadzment vraca sa Havaja. OEM-i su saznali kad i mi svi.

E sad, da li je ova pricica kompletna ili je ovo cover-up za nesto teze - videcemo, teorije zavere tek treba da krenu :D

I Anand je malo protivrecan, SATA II je legacy sa Ibex Peak-a pa se bug provukao (a P55/H55 nisu naravno pogodjeni), pa onda B stepping je jedini pogodjen dok ES primerci nisu (sto znaci da su se zeznuli u dizajnu mnogo kasnije).
