MK-13 xtreme tests

Radeon 5870
Furmark xtreme
Prolimatech MK-13/PK-1
Thermalright VRM-R5 + 1600rpm
San ace 6000rpm
~20c ambient

Fiecarui cooler i se va testa abilitatea de a face fata unui TDP extrem, cu singura (si dificila de indeplinit) conditie ca vrm-ul sa fie racit foarte bine pentru a nu deteriora placa.

Cei peste 100 de amperi ce trec prin cele 4 integrate VT1195SF sunt generati fara vreo problema de fur in modul extrem, la 1.35vgpu ne apropiem de limita de 40 de amperi a unui chip.

Se poate observa eficienta lui VRM-R5, la ~133 amps VDDC curent temperatura este tinuta sub 70c. Problema vrm-ului (prezentata in postul de mai sus) este rezolvata dar din pacate Mk-13 nu poate sa face fata unui TDP foarte mare (aruncati o privire la GPU Temp #2).

Va fi interesant de vazut ce se intampla pe GTX 480, mai ales ca pe site-ul producatorului se specifica ca nu este recomandat overclocking/overvolting pe GF100.

Foarte frumos, arata si bine coolerul ala pe 5870 si cred eu si pe alte placi..

Daca ai testat cumva ,,, Thermalright HR-03 GT cu un fan de 120mm (maxim 3000 rpm) este mai bun ca un Accelero S1 cu 2*120mm (si turatie identica) ? Spitfire-ul este mult mai bun ca HR-03 GT-ul ?

Nu am avut HR-03 GT/Accelero S1 dar nu cred ca este vreun cooler vga sa se apropie de Spitfire, in special la bench.

@ramiro, crezi ca s-ar putea monta Thermalright VRM-G2 impreuna cu Accelero XTREME Plus pe un ZOTAC GTX 480?

Dar impreuna cu MK-13 ar merge? Pe site la Prolimatech spun ca nu e compatibil cu GTX 480. Incompatibilitatea ar veni din lipsa racirii VRM care sa zicem ar fi suplinita de un VRM-G2?

Merge cu MK-13, temperatura in jocuri e ok dar furmark xtreme e crima pe fermi.

In primul screen se vede temperatura in Far Cry 2 (3 long loops), 1600rpm/VRM G2 pasiv/20c ambient/open stand/default vGPU (0.99v)

In screenul doi am rulat furmark xtreme in aceleasi conditii dar coolerul nu face fata, am atins 100c dupa doua minute.

Va imaginati ce inseamna fur xtreme cu ~1.4v pe GF 100?

Default GTX580 reference, GTX580 DirectCU II si GTX 480 - consum in furmark la 1.2vGPU



Am verificat consumul celor trei placi video in furmark la un voltaj in load de 1.2v, masurat cu multimetrul. Platforma a fost aceeasi in toate testele iar temperatura ambientului a fost in jur de 15 grade celsius.

In principal am vrut sa vad diferenta de consum intre GTX480 si GTX580 dar am facut si teste la voltaj stock sau cu protectia de OCP dezactivata, in cazul placii de referinta GTX580.

Sistem de test

CPU - Intel 980x
RAM - 6gb DDR3 2000 cl7
HDD - WD 640 AAKS
MB - EVGA 760

ASUS GTX580 reference



fur 1.8/1.2v - 408watt
fur 1.8 EX/1.2v - 410watt

fur 1.9(dynamic cam)/ocp/1.2v - 573watt
fur 1.9 EX/ocp/1.2v - 593watt
fur 1.9 EX/8xaa/ocp/1.2v - 595watt
fur 1.9/1.2v - 600watt

ASUS GTX580 DirectCu II



fur 1.8 EX/1.2v - 580watt
fur 1.9/1.2v - 590watt

GTX480 reference



fur 1.9/1.2v - 760watt

Consumul la o temperatura de ~70c a fost de 690watt, din care trebuie scazut consumul ventilatorului de 6000rpm (~50watt din priza). Din aceste doua screen-uri (1, 2) observam ca o crestere de ~30c in temperatura GPU-ului aduce un consum cu 40watt mai mare, lucru care trebuie luat in considerare cand facem comparatia intre consumul lui DirectCU II si consumul referintei.

Consumul inregistrat la DirectCu II este mai mic (aici se observa ~540watt la ~ 45c, eu deconectand ventilatorul pentru a permite temperaturii sa creasca pana la ~ 70c pentru a avea o comparatie corecta) fata de referinta GTX580 cu ocp-ul dezactivat pentru ca era racit cu TRUE+1600rpm si avea temperatura GPU-ului mia mica.

In privinta consumului lui GTX480 putem spune ca dupa scaderea consumului ventilatorului de 6000rpm, ramanem cu ~ 50 watt in plus trasi din priza fata de gtx580, in aceleasi conditii de voltaj si temperatura (1.2v/70c)

In incheiere am facut un test cu GTX580 reference la voltaj default, cu si fara protectia de OCP.



fur 1.8 EX/1.0v - 342watt
fur 1.9 ocp/1.0v - 454watt

Daca la voltaj default observam o diferenta de consum de 112watt, la 1.2v aceasta diferenta creste la aproape 200watt (aici - 410watt fata de aici - 600watt, acelasi voltaj folosit, 1.2v MM load)

De remarcat ca furmark 1.9 in cazul driverelor folosite de mine (262.99), a dezactivat ocp-ul si in cazul in care nu a fost bifata casuta OCP.

In cazul lui GTX480, la voltaj mare si temperatura mare atingem nu mai putin de 760watt trasi din priza, la o temperatura de 99c (la 100c se activeaza protectia), leakage-ul fiind imens.

Prima poza e belea! Sefii de la nvidia i-au chemat pe baietii responsabili cu racirea(placilor evident)si le-au zis:uitati ba,asa se face!!!Bravo Ramiro,respect pt munca depusa!

Wooow!!! 760W in priza pt o configuratie single gpu e foarte mult.

Racire sanatoasa=>placa video e fericita + riscul unui atac de cord mult micsorat la intalnirea cu factura electrica

Thumbs up ramiro!!!

1000+ watt, daca era un GTX480 [email protected] 1.45v puteam atinge 1300 watt fara probleme.

E bine c-au inclus thermal adhesive.
Nefiind duo component se poate solidifica, cică se recomandă a se folosi la max o săptămānă de la achiziţionare. Şi cāt stă īn depozit?
Curing time 60min.

The PFB series is one of Delta's newest DC Fan product lines introduced in 2006. This model, PFB0912DHE, is the highest flowing 92x38 Delta fan to date. When even Delta's own catalogue appropriately names the DHE a drastically high speed fan, it should tell you something. This particular Delta part already has its own established reputation cooling Harley Davison wide-glide motorcycles across the United States as well as special SuperMicro power supplies.
