GTX780 DCII vrm temps?

post #1 of 12
Thread Starter 
Hi guys, due to some conflicting conclusions, and variables, i decided to ask for help from owners of this card to put my misery to end tongue.gif

Can anyone please, test this card, on some really demanding benchmark/game, for 30 minutes loop with fans on 70% and max oc, with voltage slider to max, and power target to 110%

Also the game/bench should be with absolutely max out settings ain't matter if 15 fps, in order to get general idea of what vrm temps should be after long gaming session with oc smile.gif

Thanks in advance thumb.gif

Why are you worried about VRM temps? I haven't heard about anyone having issues with high VRM temps.
What is more important is core temp for overclocks smile.gif

For me as well, but i must know, i don't want to go over 90-95c max on the vrms, and i must know how much headroom i will have. If not much i can go with 290/290X cards which have alot lower vrm temps this time around.

BTW core temp is kind of irrelevant, you can have 65c core, and yet unstable oc cause of the vrm's.

I think if you read the 290x custom cooling threads, you'll see a lot of people struggling with their 290x VRMs.

Here with stock cooling and stock loads, the 290x is a hair under 80C .....

http://www.guru3d.com/articles_pages/radeon_r9_290x_review_benchmarks,12.html

The DCII barely breaks 70C even on the GPU.....I no longer have them on air (on water Furmark peaks them at 39-40C @ at 32% OC) .... I recall in low 60s at stock and mid 70s .... "to the wall"

I don't understand, the temperatures you point, are for the core or the vrms, regarding air? what about max air oc, what vrm temps you had?

The page I linked to shows exactly where they are measuring the temperatures..... I don't have a thermal imaging camera so when i quote my own readings, I'm talking what what Im reading off Afterburner, Furmark, etc.

Thanks for your help i guess your answer is a bit confisuing to me. I dont know if you talk about 290X or 780DCII sadly redface.gif

What part of this numbers are for the vrm's? are there 2 vrm temps in gpuz listed? what is the highest with voltage/power target sliders maxed out, and max out clocks after prolong period? can you please test this for me, or at least put unigine maxed out for 15 mins to loop with fans at 70% you will help me alot, sorry for bothering you bro! tongue.gif

And yea, GPU-z will be fine for me smile.gif

Edit: you got custom cooling on the vrms as well? if yes, what vrm temps you had on air, sorry i'm kinda confused from your answer tongue.gif

Look at the extremerigs video on youtube....the Titan 780 all use the same block essentially and he recorded VRM temps.

23:00 mark

https://www.youtube.com/watch?v=sDyYliSo-Hw

Here's my testing: Furmark, Two 780 DCII's & EK Clean CSQ WB's & Backplate
Used EK Thermal Pads where indicated all with Gelid Extreme Paste
25% GPU OC and 20% memory OC
Radiator Fan rpm = 1183, Pump speed = 3200 rpm, TDP - 107.8 - 111.1%

03 minutes - GPU = 38C / VRM = 47C , 420 Rad In / Out = 32.1 / 31.3, 280 Rad In / Out = 31.6 / 31.2, Ambient = 22.7
06 minutes - GPU = 40C / VRM = 50C , 420 Rad In / Out = 33.2 / 32.3, 280 Rad In / Out = 32.9 / 32.4, Ambient = 22.7
09 minutes - GPU = 41C / VRM = 50C , 420 Rad In / Out = 33.9 / 33.2, 280 Rad In / Out = 33.5 / 32.9, Ambient = 22.7
12 minutes - GPU = 41C / VRM = 51C , 420 Rad In / Out = 34.3 / 33.4, 280 Rad In / Out = 34.0 / 33.4, Ambient = 22.7
15 minutes - GPU = 41C / VRM = 51C , 420 Rad In / Out = 34.5 / 33.6, 280 Rad In / Out = 34.1 / 33.4, Ambient = 22.7
18 minutes - GPU = 41C / VRM = 51C , 420 Rad In / Out = 34.6 / 33.7, 280 Rad In / Out = 34.1 / 33.5, Ambient = 22.7
