sunt diferente foarte mari intre gpu-uri , daca la nvidia eram obisnuiti de un maxim 50 mhz ...vine amd si ne arata diferente de 300mhz intre exemplare
Nu e chiar asa ! Cand racesti GPU pe subzero si urci spre 1600-1700MHz vei si nevoit sa lasi memoria ceva mai jos ca sa obtii si ultimul Mhz din GPU (oricum 1900-2000MHz iti ofera bandwidth suficient pentru a nu limita performanta).

Nu exista CB la seria 7000 de la AMD, trebuie doar fortat PCI-Express Gen 2 pe anumite placi de baza pentru a rezolva problema asta (RE 4 cu ultimul BIOS nu are CB de exemplu chiar si in PCI-E Gen3)

Nu exista 300MHz intre exemplare, asta e o aberatie (pe aer, apa sunt maxim 50-75MHz diferenta). Problema principala e ca HD7000 nu e o placa simplu de benchuit pe subzero. Pentru a scoate totul din ea ai nevoie de RE4, BIOS special, foarte multe moduri, skill, rabdare si mult azot

am avut eu exemplar ce mergea 1080 maxim , facut hw mod , scoasa la frig nu am avut scalare decat 10 mhz... orice ai zice sunt diferente destul de mari intre ele ... altfel dadeam toti 1400 mhz

Cred ca era ceva in neregula cu placa aia, eu am testat 3 bucati HD 7970 si 2 bucati HD 7950 si nici-una nu a mers sub 1200MHz pe racire stoc si ambient de ~26 grade

eu am 2, si intr-adevar, fl;oare la ureche 1200MHz, din prima, fara probleme. am ramas surpins ca oc-ul se face la fel de stabil indiferent ca e o placa sau sunt 2 in cf

sunt placi ce pot maxim 1100 sau mai putin( cazul meu nu este unic) , deaia s-a si scos alternativa HD7950 , acum cum ti-e si norocul , dar mi se pare cam aiurea la unu sa-i merga sub 1100 si la vecinu( vezi hwbot) 1400 stock... acum eu nu am avut decat 2 , dar din ce am testat pot spune ca scalare cu voltii NU au nici 5 mhz , de la 1.3( limita software , care in load e ~1,270) la 1,4 - 1,450( limita OCP) nu am avut scalare, iar placa merge 1300 indiferent de ambient.. poti sa pleci cu ea la polu nord

evident ca merg atata timp cand fiecare gpu merge peste 1200MHZ, dar ia sa fi avut una bleaga de 1100 sa vezi atunci ce frumos merge

Pe aer nici eu nu am vazut scalare peste 1.25 - 1.275v, dar pe subzero scaleaza cum e si normal

Ai pus cumva platforma aia langa calorifer?

Daca da, aia e nesimtire

Thermaltake cu design de calorifer (si chiar eficient designul).

Nu am mai vazut modelul ala. Eee....mai altfel.
In plus nu m-am gandit ca folosesti carcase.

Pare a fi din aluminiu asa ca il suspectez pe Rami ca vrea sa achizitioneze un buldozer si ceva GTX480 (poate 2x pentru crossfire) sa nu mai foloseasca alte sisteme de incalzire pe viitor. Nu tu soba sa spargi lemne, nu tu sclav la furnizori. In plus, chiar daca consumul de curent nu va fi neglijabil, are posibilitatea sa se relaxeze la un solitaire, deci numai avantaje.

in mod cert va iesi un "crossfire" perfect cu cele 2 GTX480, DanutzuAC ... cred ca ai vrut sa zici SLI

mare dihania de carcasa domnu' Ramiro

kagula323 Ce le stii tu ca un om mare...
E creatia mea literara incadrata la genul SciFi asa ca se cheama cum vreau eu.
Si de fapt se cheama crossfire pentru ca o placa e pentru Physics si alta pentru SLI. De asta-i SF

On topic (oare): Sincer e chiar faina carcasa. I like it. Banuiesc ca e si grea dar si silentioasa.
E mai nasol cu oaspetii care te intreaba: Da tu cu ce te incalzesti, cu radiatorul ala de sub masa sau ai soba/centrala?

eu recomand sa isi mute caloriferul domnul ramiro (si comment-urile ce au legatura cu el) in threadul de carcase si sa continuam sa admiram aceasta dihanie de carcasa acolo ... daca e posibil, il rog sa faca si cateva poze mai detaliate carcasei

Thermaltake Tai Chi, 20kg goala si telescop pentru sustinerea placii din lateral. Loc cat china sa bagi un sistem watercooling doar pe tabla din lateral.

On topic: Fain exemplar de 3850 ai prins.
