i got my hands on a cheap secondhand tesla m2070 which is passively cooled but i modded it with something like a heat duct and a fan so it should be ok in my opinion.. the problem is since it is a not a workstation product i can't get out the temperature readings from the sensor with nvidia-smi.exe commands or other harware monitor programs:
from http://microway.com/hpc-tech-tips/2011/ ... your-gpus/
the tesla card is used as secondary card next to a quadro 4800 which i did not use for rendering yet.You’ll notice that unfortunately the M-series passively-cooled Tesla GPUs do not report temperatures to nvidia-smi. This is because the temperature data is reported directly to IPMI, allowing the system’s BMC to properly control chassis cooling.
the other specs should be just fine:
mobo: ASUS P6T7 WS SuperComputer
24gb RAM
1500W power supply (this machine is meant to hold another 2 teslas in the future...)
win7x64
ok now my troubles:
octane preview window works just fine but when i hit render the at 2500x2500 the rendering will stop after 5 or 10 minutes. i checked gpu usage via nvidia.smi a couple of times and noticed that the preview window always stays at 99% while after hitting the render button the cpu usage mostly is 99 but sometimes falls down to 85 but a second later it is 99% again. after the stop i immediately launched the octane preview window and that one worked (the gpu had nearly no time to cool down while doing that).
i tried both path tracing and direct light with diffuse bounces.
so my question: does the preview window something other than the render button? does a higher resolution draw more power out of my gpu than the preview window?
any help is appreciated (also regarding reading out that gpu temperature)
tnx.

p.s. if i am sure it is a temperature problem i am thinking about a water cooling solution especially when there will be 4 gpu's inside that WS...
