I would try to export within 32 Bit for those banding critical passages. Your DPX export is just 16 Bit … That might reduce quite a lot of the Banding.

Hi Dan,

Thanks for the quick response. No, I did add a node. I also tried to add a new version but without success.

Might there be something else?

Thanks,
Arty

Hi Kelly,

It’s pretty straight forward and works like a charm. You get a Y 6 pin splitter cable, like this one:
https://www.amazon.com/CB-6M-68F2-6-pin-PCI–Dual-Cable/dp/B005GWFZ8Y/ref=sr_1_10?ie=UTF8&qid=1314982428&sr=8-10

So you have the two needed for 5870 and one extra for the Quadro 4000.

This setup works really well. Just the noise before you start to use the Quadro is annoying. It’s such a strange thing that you have to use the card heavily before the fan turns down. Probably a driver issue.

Besides that everything works really well. I did already some stress test, having the Mac Pro running constantly for more than 72 hours and no sign of overheating.

Hope that helps!

All the best.

Sascha thank you for the test! Will run it over the weekend …

Concerning the noise, this is really strange, when I start up the Mac Pro the expansion slot fan is going up to 1900 RPM. (normal without Q4000 it’s around 800 RPM). When I start to use the GPU but just when I use the GPU the expansion slot fan goes back to normal behavior.

So my startup with the Q4000 looks like the following: I boot up and start Premiere (Mercury enabled) play a native RED file with some effects applied to it and voila the fan goes down to it’s normal state around 800 RPM.

One would think that the fan is going crazy when the card is used most but this is not the case. It needs to be used. There was a thread to this in the NVIDIA forums where other people reported the same behavior. I reckon it has to do with the NVIDIA drivers …

The system is running on 10.6.8 with the latest drivers for the Q4000 (general and Cuda).

I really enjoy working with my system when it’s quiet. It works with the Q4000 but the procedure is to get quiet is really annoying.

Tips are very welcome.

Thank you!

Hi Tim,

Thanks for your quick response. Your explanation sounds exactly the noise we are having. Glad that it seems to be normal. Rain is coming …

What a great investment in render speed!

Hope you are well and thanks again.

Hi Tim,

We just got the same setup as you. Our two extra quad core minis arrived today. Everything works as expected but it’s a lot of noise. Do you have the same issues? When Net Render is running and maxing out the machines the noise almost gets unbearable. For how long did you have them running?

Ours just rendered a 4K sequence with 300 frames. The speed is amazing and they are a great addition to our network but the heat concerns us a little bit. The CPUs run with 90 degrees (celsius) / 360 kelvin. Compared to a 12 core 2.93 GHz Mac Pro, it’s a lot.

Would be great to get feedback from you since you are running the same setup.

Thank you!
