Default Intel Core i7 7700K ? Studiu de overclocking ? Partea I ? Aer & AIO

Core i7 7700K – Overclocking pe aer   Acum cativa ani overclocking-ul era destul de previzibil si intuitiv, existand in majoritatea cazurilor o scalare direct proportionala a frecventei cu racirea si tensiunea de alimentare aplicata.*Se pare ca tick-tock-ul folosit de Intel cu succes in cazul procesului de fabricatie / arhitecturii se poate aplica la fel […]

ala e exemplar bun ce ati avut voi
sunt curios daca va fi si pentru muritori la fel...

dat fiind faptul ca se vand deja cu 2400-2600 lei cele de 4.8 GHz si 2800-3000 lei un procesor care tine 5.0 GHz din cele existente, ma duce cu gandul ca iar e loterie pura si nu-s asa multe care sa tina 5 GHz sub 1.3 V daily use...

by the way, la cel din review e stock, nu i-ati facut delid, nu?

E un procesor retail...o sa notez si batch-ul cand ma intorc la birou.

Da, unele o sa mearga asa, unele mai prost, unele mai bine.... Asa a fost intotdeuna. Nu am avut 50 de procesoare, nu facem binning...asa merge procul pe care il avem.

Si da, am avut 2 7700K, un 7600K, un 7600, toate retail si un 7350K ES...

Procesorul respectiv este considerat a fi unul de 5.3 stabil ,de aici si pret premium (625 ).
Sunt care merg 5 ghz la 1.35 sau mai sus,alea sunt mai ieftine(400 ),important este ca merg 5 ghz.

yap, dar cu cat se duc mai jos la voltaj la 5 gigi sunt mai scumpe...
probabil au fost preturi sus si ca nu prea se gaseau deloc, pe ebay mai apareau si la 6-700 usd ("chioare", la nimereala) pentru nerabdatori :P
hype-uri... dar acum au aparut si la noi oficial:
http://www.pcgarage.ro/procesoare/in...0k-420ghz-box/

Edit:
am dat si comanda deja, sper sa ajunga sâmbata, vedem cum arata alea pentru muritori :P

Frecventa cache-ului este independenta de cea a nucleului, inafara de ceva caldura suplimentara nu influenteaza cu altceva stabilitatea.

Pai vrea cam 70mv in plus pentru a se stabiliza 100MHz mai sus, ceea ce mareste caldura degajata destula de mult. Daca la 5GHz cu 1.27v aveam ~85 grade, la 5.1GHz cu 1.35v saream rapid in throttle
