Momentan am urmatoarea configuratie pentru minat LTC si nu numai in functie de profitabilitate:
placa de baza P7p55 LX + procesor i3 + HDD500 GB + 4GB DDR3 + Sursa Nox Urano 750W + Placa video Sapphire 7950 + un ventilator de carcasa Stock
Intentionez sa mai cumpar o placa video si nu stiu ce sa aleg 7950 sau 7970
Ma gandeam la modelul 7970 mai exact acest model http://www.dc-shop.ro/index.php?main_page=product_info&products_id=110873&utm_source=price-ro

Credeti ca suporta sursa mea Nox Urano de 750W sistemul de mai sus + cele 2 placi video 7950 + 7970 ?
Sau sa cumpar tot un 7950 ?
Din ce m-am interesat 2x7950 ar merge ok cu cei 750W, daca cumpar un 7970 pot sa ii mai scad si voltajul nu ? sa o aduc la un consum apropiat de 7950.
Astept pareri, si eventual recomandari daca aveti un anumit model de 7950/7970 sa-mi spuneti ce viteza obtineti ca sa imi fac o ideie ce sa cumpar Cheesy

Orienteaza-te catre o sursa 80+ Gold eu as recomanda :

Sursa am, doar ce am cumparato, eu vreau sa mai cumpar o placa video care sa mearga cu sistemul de mai sus, am facut ceva calcule pe site-uri care calculeaza puterea necesara cu 2x7950 e ok, dar cu 7950+7970 sunt la limita ... si nu vreau sa am neplaceri sa nu o pot folosii

Nu stiu cum sa ai acces la managementul puterii CPU sub linux... In Windows, puteai sa pui procesorul la 20% consum si diferenta de putere o consuma 7970 :-)

da, atunci e alta poveste...

Eu spuneam doar cum poate sa salveze cativa Wati de la procesor sa-i foloseasca pe GPU-ul care e mai mare consumator.

Te duci asa...

1. Control Panel
2. Power options
3. Vezi care e planul activ si dai click pe "Change plan settings"


4. Dai click pe "Change advanced power settings"


5. Schimbi valoarea maxima a puterii pe care o ia procesorul, in procente. Atentie! Puterea de calcul si viteza procesorului se va diminua.
