Mislim da to nije takav problem, da bi se riješio smanjivanjem takta.

How does the TLB erratum occur? All AMD quad-core processors utilize a shared L3 cache. In instances where the software uses nested memory pages, this processor will experience a race condition.

AMD's desktop product marketing manager Michael Saucier describes a race condition as a series of events "where the other guy wins who isn't supposed to win."
In the software world, a typical memory race condition occurs when the memory arbiter is instructed to overwrite an older block of memory, but write the old block of memory to somewhere else in cache. In the instance where two arbiters follow this same rule set, its easy to see how a race condition can occur: both arbiters attempt to overwrite the same blocks of information, resulting in a deadlock.

From what AMD engineers would tell DailyTech, this example is very similar to what occurs with nested memory pages in virtualized machines on these K10 processors.

nebi htio palit vatru ali ni Phenom nije bez bugova, koliko mi je poznato CPU voli smrznut stroj pri većem opterećenju
Više možda saznam kada/ako mi uleti koji primjerak na testiranje

Mislim da bi ovo bio kraj trakavice o errata u Phenom procevima

The reason they were able to proceed with the launch is that this particular erratum is fixable via a microcode update (done using a motherboard BIOS update). Basically, the part of the L3 logic that causes the problem is disabled. However, running the fix instills a performance penalty, because of how the L3 cache’s throughput and latency is affected. There was no way to know exactly how performance would be affected, except for the “around 10%” estimate that has been floating around. Fortunately, our friends at Tech Report have obtained a retail Phenom 9500, and tested its performance before and after applying the patch on an MSI motherboard.

The results were even worse than expected. When looking directly at cache memory performance, bandwidth dropped by as much as 38.7%, and latency slowed down by over 50%!

Of course, what really matters is how the actual programs we use every day are affected. Tech Report ran a full suite of Worldbench tests, to find that the performance drop ranged from around 5% to as high as 50% in programs like Firefox. The average drop in performance in their tests ended up being 13.9%.

Eto da i ja pomognem Amd/Ati-ju i moj Q i ploca za koji dan lete na trznicu. :D

Ma stalno mislim na tu plocu...jbga

@nino
Pricekaj prvi mjesec (ako zelis/mozes) i kupi 9600 Black Edition (10€ skuplji od obicnog) stepp B3 i mislim da neces pozaliti. Koliko sam citao na XSforumu vecina opcija u BIOSima 790FX ploca jos nije ni otkljucana! :(

Odakle ti ta informacija?

2.35v za DDR2 memoriju je ništa, ili ti pričaš o DDR3 memorijama?

Autor Razer (Post 894164)

Ovo nikako nije dobra vijest...

Na stranu OC, no AMD ima i gro ostalih problema koje se vežu uz novog Phenoma, kad moraju srljati kao guske u maglu :nono:

P.S. moja greška u vezi DDR3 memorije...

Autor Jerry (Post 894032)

Izgleda da Vdimm veci od 2.35V zauvijek ugasi CPU! :(

Autor Razer (Post 894174)

U čemu je velika stvar? Jedno je kad rikne jedan procesor na njih par stotina (karikiram), a drugo je kad rikne četiri procesora za redom zbog iste stvari...očito je da su Phenomi puno puno osjetljiviji na te stvari. Ako uspiju to riješiti super, ako ne, neće biti dobro...

Buduci da je mem. kontroler u procu ne mozes gledati stvari na FSBovki nacin.

uostalom, amd je vec na grafickama glumio djeda mraza ovaj mjesec, ne moze sad i procesore poklanjati :)

bez da pogledam linkove moram reci da mi je uvijek bilo jasno da intel nesto mulja jer sama razlika u kolicini casha na intelovim procesorima u odnosu na AMDove je dovoljna da im za duplo podigne proizvodnu cijenu procesora.
intel unistava konkurenciju sada kada ima priliku. da ne spominjem medijsku hajku na AMD. neka netko prica sta hoce ali nisam procitao niti jedan objektivan clanak amd vs intel u zadnjih par godina, racunajuci i one kad je amd bio bolji na gotovo svakom polju
