Blackmagic Forum

Hello group,

I'm looking to build a system. I will get the New Mac Pro w/32gig ram and the 2x 700 GPU

But I've read a lot of posts here and Creative Cow with people having issues with this system.

Has it been cleared up?

Thanks!

Evan

nMP people... any issues?

Those on the 10.10.2 OS are reporting their previous issues seem to be fixed.

Thank you, Peter

Yes. Working on nMP: 2.7 GHz 12 Core with 64GB Memory with dual D700. OS X 10.10.3

No issues.

I'm same as Rob with no problems on Mavericks. Will be updating to Yosemite soon, I assume bugs have been ironed out…

Still getting the horizontal line glitches here with OS X 10.10.3.
nMP 3 GHz 8-Core Intel Xeon E5
D700 Graphics cards

Happens after the machine has been working for a while and gets hot.

horizontal glitches sometimes, in dailies works never happen.... in a complex timeline (4K-2K) with a LUT, 8-9 node, plus grain on V2 in overlay sometimes u need to reboot machine. Now i'm rendering material without "use display GPU" and without the second 27'' monitor connected to the system. I think this allow the machine does not get too hot. Feedback please from other colourist....

nMP 8core, D700, 32gb ram, 2 27'' Thunderbolt cinema display, Ultrastudio 4K, thunderbolt storage, OS X 10.10.2, Davinci Resolve 11.3, Desktop Video 10.3.7, Filmconvert 2.02.

to rule out that it's a consequence due to overheating, could you try the same project of davinci via bootcamp and report your data? If there were no artifacts would mean that it's something that maybe can be fixed, Isn't it?

I'm having the same issue.

Working on a 4K UHD project, with 5-6 nodes maximum, but using Temporal Noise Reduction in almost all shots.

I can't render even 1 frame, as soon as I click to render it starts to glitch and give me the information "GPU memory is full".

I'm using a Mac Pro (6.1 / 8 cores / 32Gb ram / D700).

I tried both Windows and Mac versions.

There is any solution on this problem?

I have a cheap workaround (though it's not a full solution):

1) don't use any TNR in the grade at all.

2) render out the entire movie as ProRes 444 files.

3) take the ProRes 444 files back into Resolve, start a new session, and then apply the TNR as a separate pass.

The alternate would be to use a 3rd party program like Neat Video and use it in a mode that only uses the CPU and not the GPU. My own gut feeling is that the GPU in the nMP is overheating, because I can get the D700s to work after the machine is cooled off. But just for a 20-minute reel or so, not a longer continuous piece. Strictly my opinion. 10.10.2 has not solved the problem for me, but I have yet to upgrade to 10.10.3.

I have been able to use limited amounts of real-time TNR in little bursts here and there, but I'm not a fan of applying lots of noise reduction all the time all over the place. I think it's just too much. I only use it when we really need it. If the whole show is noisy, I chide the DP for underexposing and/or underlighting.

I have had good success with this. Also, Neat Video, as a way to analyze the optimal allocation of GPU and CPU to render NR with other GPU heavy demands and I have had good luck with this. I’m kind of ticked-off at Apple for marketing the pricey nMP as a pro level rig when it can’t cut the mustard in Resolve in a 20 minute short. Marc’s comment about rendering when the computer is cool is also a solution I have used.

I'm considering buying a Mac Pro, but I'm scared to do so..Scott can you tell me if you're still having problem with your Mac Pro and davinci resolve. Thanks

I am still having mega issues with the GPU. Just bought a new MacPro because the old one's GPU died. The brand new tricked out MacPro with only Davinci Resolve on it is basically useless with tons of glitches and I am very frustrated with this solution. I am either going back to a tower with Cubix, or going full on Linux.

Omg wow I can't believe we're still seeing problems with this machine.

Same issues here.

I've been using the NMP with Premiere since the computer was shipped in March of 2014. Also been having GPU issues since day one. Even now I'm still working with Apple tech support. No solutions yet. Just a big waste of money and no recompense from Apple.

Still seeing the horizontal glitches on my machine.

NMP 8 core D700 GPUs
Resolve 11.3.1
OS X 10.10.4
Desktop Video 10.4.2

The weird thing is I can work for a couple days with ZERO problems and then suddenly I can't work for more than 5 minutes without glitches. SOMETIMES, a restart and cool down will fix for about a half an hour, If I'm lucky.

I have had some luck with the free program iStat, which will report current internal Mac temperature and will also allow you to manually bump up the internal fans to maximum. If you let it cool off for about 45 minutes, the machine will go down below 100 degrees. Bring it back up, relaunch Resolve, and immediately render the file. I've found it's generally OK until it goes over about 135 degrees. I also have an external fan on the machine, but I'm not convinced it does much good.

Thanks, Marc.
I have iStat and have been doing that for a while now. Letting it cool down doesn't always work. It's seems a hit or miss thing. My usual actions, if cool down doesn't work, is to repair permissions. Then shutdown for a few minutes and reboot. Again Still doesn't always work. Somedays there is just no way to get it working correctly. Other days, I have little or no problems. Of course, it acts up the most the closer it gets to deadline, haha.

FWIW, we have second NMP with the same specs that we have tested. It also has the dreaded render glitches.

Are those temps in F or C?

I guess I should count myself lucky as I don't have any of the graphics issues noted on this forum, but then my workflow is rather simple and I don't use noise reduction.
Depending on the codec I'm transcoding (either to ProRes or DNxHD MXF generally), I find that the codecs that are heavy on CPU will get the fan spinning fast enough for me to just hear it, but GPU intensive codecs get the fan running hard. iStat tells me the fan gets up to 2600RPM and its like a big hair drier. My machine seems happy to cook along for many hours at this intensity without skipping a beat, and its nice to put cold hands over the jet stream of hot air to warm them up occasionally too.
My MacPro sits on my desk in a corner, my office is cool in winter and warm in summer, but I have not noticed any real difference in the fan behaviour from room temperature.
For a while I was running multiple monitors but found Resolve faster with just one monitor. I also tell Resolve to ignore the 4K Ultrastudio unless I need to use it to capture or playout to tape because I found that Resolve would occasionally hang if it knew the 4K Ultrastudio was connected.
Looking forward to 12 and seeing what speed improvements that it will hopefully bring.

I can vouch for Neat Video as an reliable way of doing NR. Works great and doesn't choke or boil my nMP.
