Btw, ja i dalje ne smatram da je FX8320 bolja kupnja od FX8370. 500-600kn nadoplate za "parsto" mhz u najboljem slučaju nije neka špica

Ja sam isto imao sreće, moj FX8320 fino poteže (4,6 na 1,35V, Držao sam ga i na 4,7 na 1,37V) ali glupo mi ga je silovat, pogotovo s ovim hladnjakom koji nije dorastao zadatku. A jednostavno ga se ne isplati silovat jer porast perf nije proporcionalan potrošnji i zagrijavanju preko određene sweetspot točke (u mom slučaju 4,4Ghhz i 1,3V).

Drže se ti FX-evi još, drago mi je to vidjet

Još ako ćemo zaista ubuduće ćešće biti svjetoci bolje oprimizacije za višenitnost, na konju smo

I jesi i nisi u pravu.
Nije stvar samo u parsto mhz koje mozes dobit sa OC 8320 da dodjes na razinu 8370. Stvar je u tome da ce istu stvar 8370 drzati sa puno manje struje i puno je hladniji.
Moj konkretan primjerak drzi 4,9 sa 1,375 vCore. Sumnjam da iti jedna starija Vishera to moze.

Ocito je da FX8370 i 8370E imaju puno manji leakage od starijih Vishera.
A siguran sam da je FX8370E najbolja kupnja trenutno jer ima jos manji leakage od 8370.
Oba chipa mozes drzat 24/7 na 4,8/4,9 ghz sa high end zracnim hladjenjem sto je u slucaju starijih Vishera ravno cudu.

Primjer1: Ako imas FX-8350/8320 onda se ne isplati prec na 8370
Primjer2: Ako kreces od nule onda 8370 ili jos bolje 8370E all the way.

Isto tako je gotovo sigurno da ces u 90%+ primjera sa 8370 i 8370E dobit "golden chip" sto u slucaju 8350/8320 je na razini lutrije.

P.S. Prime95,sat vremena,smallFFT tCase nikad nije presao 50. a govorimo o 4,7Ghz. Uvjeren sam da starije Vishere to ne mogu.
AMD je ipak napravio dobar posao jer su svi FX serije 8xxx future proof i sa vremenom ce postati samo jos bolji sto je paradoks u danasnje vrijeme.


EDIT: nasao sam sto kaze Stilt o Visherama:

Piledriver module based Vishera die has been mass-produced in two different die revisions since the prototyping phase.
While all of the revisions have the same major die version (OR-C0), the minor revision has changed.
Initially the first mass-produced die revision was "India" (OR-C0i, prototype and ES only), the second revision was and still is "Juliett" (OR-C0j, retail) and now finally...
The "Kilo" revision (OR-C0k) a.k.a "King Vishera" a.k.a "Vishera Type-K" has arrived.

The "King Vishera" is initially only available in the new models, FX-8370E & FX-8370.
This is most likely the case with FX-8320E also, however I have not been able to test one of them personally.
The new version is likely to be phased-in at least in the other high-end models such as FX-9590 and at some point in all of the remaining models also.
The alledged metal tapeout of the new revision (alledgedly) occured in the beginning of July. So the only way to get a newer revision part is to get one of the new models, atleast in the beginning.

The differences?

- On average 18% less leakage*1 (0-38%) for FX-8370
- On average 53% less leakage*1 (14-106%) for FX-8370E
- Up to 300MHz higher overclocking margin *12
- 100mV less voltage required for the same clocks on average *1

*1 - Compared to an average FX-8320 or FX-8350 CPU
*2 - When not restricted by the cooling or the motherboard (VRM)

The E-version is the best choice for air or water cooling thanks to the ultra low leakage characteristics.
The non E-version does the same clocks however it might require use of a higher end motherboard (with better VRM) and high-performance cooling.
The non E-version has significantly better overclockability under sub-zero temperatures (phase, LN2) since the leakage levels of the E-version are too low for the purpose.
Having an ultra low leakage characteristics is great under normal conditions however under sub-zero temperatures the voltage requirements become a issue.
Basically the low leakage part exhaust the usable range of supply voltage prior reaching it's maximum frequency.

Based on my own tests, I would estimate that >95% of FX-8370 & FX-8370E parts will reach 4.8GHz frequency in 24/7 without a custom watercooling or a ultra high-end motherboard being a requirement.
As long as the temperature (see below) stays =<65 degree C or 149 degree F and the motherboard has even remotely a sufficient VRM you'll be fine.

On a high-end motherboard and a custom watercooling 5.0G - 5.2GHz+ should be doable in 24/7 use with a good specimen.

These chips still draws a vast amount of power when overclocked so the final overclocking potential is basically just the matter of cooling.
The maximum recommended temperature during the worst case stress is 65?C tCase.
