Resolve 10 GPU memory full and keeps crashing

Hi

I installed Resolve 10 from the BMPC 4K's dvd in package. A few seconds after start up it shows a message that GPU memory is full and while grading it gets freezes when i press cmd+z or when i add contrast. Resolve 9 used to work perfectly.

2.8 GHz Quad-Core Intel Xeon
12 GB 1066 MHz DDR3 ECC
ATI Radeon HD 5770 1024 MB
OS X 10.8.2

Your video card only has 1GB of VRAM. The minimum system requirements are clearly stated in the release notes to be 2GB.

"We now recommend a minimum of 2GB of GPU RAM for HD image processing and greater than 4GB of GPU RAM for 4K images..."

So as you can see, since you are working with 4K material your system is completely under powered. Of course you are getting out of video memory errors, because you are out of video memory. Furthermore, since you only have a single GPU installed, what little VRAM there is also gets shared by the framebuffer for whatever monitor(s) you have connected. Check the Mac Configuration guidelines. Or buy a GTX 770 4GB and install it in the lower PCIe slot for dedicated GPU processing.

i have been using Resolve 10 successfully for a while on my Rev A Retinal MacBook Pro. then, and I'm not sure why, i get hard freezes forcing me to force shut down.

now if I do a fresh restart and don't run FCP or any other heavy apps, DaVinci runs great.

what changed? did the requirements change?

I'd love to use DaVinci but may have to use something else more stable.

Your post is not really descriptive enough to give any indication of what is wrong, but for starters, as has been posted several times already in this forum, you should force resolve to use CUDA on a rMBP. Go to the Resolve Preferences and choose the "Video I/O and GPU" section. Make sure the GPU processing mode is CUDA and not OpenCL or Auto. Also make sure you have the latest version of CUDA installed in your OS X System Preferences. If you still have freezes after making this change post more info about what is going on or what has changed.

Also note that you must be using the version of resolve downloaded from the blackmagic website, not the Mac App Store version, in order to adjust the GPU settings.

I posted (http://forum.blackmagicdesign.com/viewtopic.php?f=11&t=19390) about this a few days ago but never got a response. Here's a copy and paste:

Complete system freeze happens at random. Most likely during scrubbing over clips or transitions.

System notes:
Model Name: MacBook Pro
Model Identifier: MacBookPro10,1
Processor Name: Intel Core i7
Processor Speed: 2.6 GHz
Memory: 8 GB
Chipset Model: NVIDIA GeForce GT 650M
CUDA Driver Version: 5.5.28 (now updated to 5.5.47)

Chain is rMBP -ThunderBolt-> LaCie 2big 6TB -ThunderBolt-> UltraStudio Express
Have also tried rMBP ThunderBolt output1 -> LaCie 2big 6TB and ThunderBolt output2 -> UltraStudio Express

Happens with media on internal SSD and external over ThunderBolt, Video GPU OpenCL or CUDA selected, ProRes 422 HQ clips, in Color tab and Deliver tab, no other apps running.

Ideas? Thoughts? Help?

It runs perfectly if I quit all apps run from a clean restart.

Hi, the last line is instructive.

Your system ram is too small.. if you only, only run Resolve that ram will be used.. if you run a concurrent app.. now your sharing too little ram.. please consider 16GB .. the config guides suggest this amount with a 12GB min.

I have exact same problem as noted above but, have the ram maxxed at 16gb. Not just the ram errors but then the complete system freeze. I did not have this issue with 10.1.1 only with 10.1.2 and now 10.1.3

It is very frustrating, only a few nodes, minor color changes and blammo, Resolve freezes, sinks the whole system. Oh, on projects that worked just fine before the updates I should add. Now I get GPU memory full and these crashes that are driving me nuts. And yes, the disable App Nap is checked.

I've tried with CUDA on, Automatic and Open CL. Nothing on my end has changed, only the latest Resolve Lite Updates so, anyone have any idea what's happened?

I am hoping for a little clarification. I have done only a handful of work on DaVinci Resolve 10 Lite. Now I get the GPU memory is full, lower your resolution window. Am I not able to use Resolve on my system? Am I to understand that I need 2 cards one for GPU and one for GUI for Resolve to run effectively? Effectively meaning I won't get the GPU memory is full window. Is the main issue that my card only has VRAM (Total): 1024 MB- 1GB of VRAM?

Yes the main issue is that your GPU VRAM is only half the recommended for HD work, and is also being used to drive two 1080p monitors, leaving very little VRAM for resolve to use for its operations. Get a secondary card like a GTX 770 4GB just to run CUDA and keep the 5770 for the GUI / Monitors.

Hey All.

Can anyone Recommend a PCI Express 2.0 that would have enough memory to run Resolve 10? i have what most people have the 5770 and i looked up the suggested GTX 770 but thats only PCI Express 3.0. i dont think i can run it on my system. Can anyone help?

... but thats only PCI Express 3.0. i dont think i can run it on my system. Can anyone help?

PCIe 3.0 is backwards compatible with 2.0 and 1.0.
