My overclocked titan and 2600k @4.5 draw about 400W under full load. That's all I can say.

PS. How quiet is your 780? What about temps and fan speed?

Its currently rendering a pretty complex scene and its 67°C.
I have not noticed any difference in noise since I installed it, so its pretty quiet.
Is 67°C okay or worrysome?
Fanspeed is around 1700 rpm

I think when it reaches 85 or something it will slow down - reduce clocks automatically. 67C is great on air.

Hi guys and girls,

Octane 2.06 PT
17.76 Ms/sec (4x580)
33.19 Ms/sec (4x580 + 2xTitan)

added 2.10
Octane 2.10 PT
20.52 Ms/sec (4x580)

added DL:
Octane 2.06 DL vs 2.10 DL
78.49 vs 77.01 Ms/sec (3x580)

added PMC:
Octane 2.06 DL vs 2.10 DL
10.19 vs 8.68 Ms/sec (3x580)

So 2.10 is faster in PT, but slower in DL and PMC ?

greetz,

Water-cooled overclocked TITAN + 3x780 6GB (I'll send more info soon here http://render.otoy.com/forum/viewtopic.php?f=9&t=42540, busy day)

Octane 2.10

DL: 189.5 ms/s (approx. same for all values of path term power)
PT 35.4 ms/s (path term power 0.3); 60 ms/s (path term power 1); 25ms/s (path term power 0)
PMC: 10 ms/s (path term power 0); 19 ms/s (path term power 1)

Temp on all GPUs ........................................... 39C
Noise level - 15-16 dB (inaudible)

Just got gtx 970, result is 4.26 Ms/sec with pathtracing and 3.61 with pmc (i'm posting that pmc works because i've seen people reporting that 9xx series has problems with pmc)

Octane 2.06 -

DL - 20.84
PT - 6.32
PMC - 4.25

Octane 2.11.1 (with/without Coherent Mode enabled) -

DL - 23.41/20.09
PT - 7.20/6.79
PMC - 1.78 (no coherent mode option)

GPU Temp at 59 degrees or below

I just ran the benchmark on my MSI GTX980:

PT: 3.66 Ms/sec
PMC: fails
DL: 12.0 Ms/sec

Driver issues? Oh, and the card never got above 67c for temp.

Edit: I'm running version 2.11.1 and I also forgot to turn off alpha shadows, here are the new numbers:

PT: 4.4 Ms/sec
PMC: fails
DL: 13.94 Ms/sec

With coherent mode enabled:
PT: 4.7 Ms/sec
DL: 17.49 Ms/sec

I looked up my old Benchmark to compare. (used release 1.20).

2x Titans Black: 15.03 Ms/sec
2x Titans + gtx275: 15.79 Ms/sec (turned monitorcard on as well)

I swapped the GPU above for 3x 780Ti in the same system with on fan less (I had to remove the bottom fan)
On target power 100% I tested the 780Ti seperately (*) is degrees for the other cards
1x 780Ti n01: 8.23 Ms/sec, 81-(41)-(30) degrees
1x 780Ti n02: 8.12 Ms/sec, (38)-83-(30) degrees
1x 780Ti n03: 8.15 Ms/sec, (43)-(38)-75 degrees

I had to tweak the GPU settings to not get it overheated (it's an AC system).
3x 780Ti: 20.40 Ms/sec,( 83-88-70 degrees)

Greetz,
