Upgrading-Dual GPU-Please Help

Hello all, I'm hoping someone can help me out. This is the first time I've posted to this site, I'm usually able to find my answer by searching the forum, but I'm stumped. I've been using the free version for about a year and I am thinking about upgrading to the Studio version, before I do I want to know if the issues I have will be resolved by it.
I currently use resolve to edit and grade short 3-5 min clips from my Phantom 4 Pro drone and OSMO for my real estate business. I shoot in H.264, 4k @ 23.9fps and typically render out in 1080p, Quicktime H.264, so I don't believe it's that demanding of a codec and application, definitely not as intensive as some of you use and DaVinci is capable of. I think my system should be fully capable of handling it.
I keep getting the message the "GPU Ram is full, lower timeline res or remove corrections", my timeline is 1080p and I get this message before I even do anything to the timeline, it happens when I add it to media pool. I would like to list a few questions and see if I can get some help.
-Why am I getting "GPU Full Message", is 8gb really not enough? If I upgrade to Studio and utilize two GPU's will this rectify it?
-When I render, it only renders out at about 10-12 fps, is this normal or should I expect faster renders, and would upgrading to studio and using two GPU's help this?
-When I upgrade and use two GPU's, how should they be configured, meaning should monitors be plugged into GPU #1 and use GPU#2 and processing GPU or vice versa. My MOBO is set up to be 3 x PCIe 3.0 x16 slots (support x16/x0/x0, x8/x8/x0, x8/x4/x4 modes)
-I am considering once I upgrade to also get another GPU and use it for my UI GPU that way I can put both of my 1070's towards processing, is this possible with the configuration I have and if so what GPU would be a good addition?
If someone can please help me out I would greatly appreciate it.

Hi...

Get a single gtx1080ti nvidia card, that should suffice.
Transcode your material to dnx intermediate codec, that will fix 95% of your issues.

For starters, try removing or disabling the 2nd GPU card, and see if that fixes anything. Note that you won't get CUDA-accelerated decoding of h.264 with the free version.

I don't think he has the second card yet.

IMHO, something is messed up with your system. I can edit UHD H.264 (Sony XAVC-S) fine, and I have GTX 970.

Now I am running the studio version, which was a massive speed improvement over 12.5.6. BUT even when using 12.5.6, I never got an out of GPU memory message.

It is true that lowering timeline resolution can greatly improve performance. On 12.5.6 I would sometimes go down to 960 X 540, but even at UHD, I never ran out of GPU memory.

Assuming you have a PCIe 3.0 motherboard, FWIU, you should be fine running both cards at x8.

Also, FWIU, designating a GUI/display only card is not a good idea starting with version 14.

I would look at a program like GPU Shark or GPU-Z to get a better idea of what's going on.

When running one card, the rule of thumb is to connect it to the slot closest to the CPU. But consult your motherboard to be sure and to find out the best way to configure dual cards. Also, their memory is not additive, in that two 4Gig cards don't give 8Gig of addressable memory. What you do get is two cards, instead of one, processing the data. Kind of like if you have a painter with a five foot ladder, adding another painter with a second five foot ladder isn't going to give you a ten foot ladder, lol.

Hope that helps a bit!

I already have two GTX1070's, I guess my question is that if I upgrade to studio will I be able to utilize both GPU's? I am considering getting another GTX1070 and using two for processing and one for monitors if Resolve 14 studio supports it?

My mobo supports pcie 3.0, my computer has all the latest tech. I was hoping if I upgrade to studio I will be able to utilize both cards.

Can you describe the process of transcoding to a dnx intermediate codec? What software does this require? Do you lose and quality in the process? What is the purpose of doing this, what does it accomplish? Thanks for the help

Walter, IMHO, there is something wrong with his system. I use a much less powerful machine and I've never gotten the same error messages, even when I was on the free version of 12.5.6.

Yes, if you upgrade to the paid version you should be able to use both cards and the paid version is considerably faster with H.264 material than than is the free version.

I find that currently Resolve performance is "ok" when only 1 of my GPUs is allocated to compute and the other GPU is allocated to display. When I try to use both of them for compute (select "use display GPU for compute") things fall apart: "GPU memory full" messages popping up on a simple timeline, stuttering, freezing up...basically unusable... This is a pity since the GPU being used for GUI-only is another 1080ti
so its capacity is being utterly wasted. I've tried updating and reinstalling drivers, using a current Windows 10 build (16299), Desktop Video 10.9.7. Not SLI configured. Resolve version 14.2.0.012

Ok that's what I figured, studio version is obviously better than free. When you say there is something wrong with my system what do you think it is? I've seen other people saying they run into the same issue but it's typically when they aren't running a good enough GPU. I've ran through all of the settings and can t figure out what is going on unless it's just a free version issue. When I was using resolve 12 and only 1 you the only time I would have a issue is when I tried to work in 4K.

I would be worried about system stability and life expectancy of the CPU.
I think 5.1Ghz is simply too much regardless of the cooling system you use.

Dean, have you tried using two cards with the Decklink card deactivated?

I have full stability without any issues and run at cooler than stock temps at only .02 above stock voltage, the 7700k doesn't typically have issues .

I don't know. I mentioned using a GPU monitoring program and being sure you have the cards installed in the correct slots. So those are some areas to start.

And have you tried running with just one GPU installed?

What I do know is that I'm running a 970 which has half the memory of a 1070, and I've never gotten the out of memory errors that you have described. Perhaps there is something funky with the source clips (like being variable framerate from a cell phone)?

I'm using footage from a DJI drone and OSMO all at 1080 24fps. I'll have to do more testing I guess to try and isolate the issue.

If you want to post a link to the file, I can test it out on my machine.

mostly is the h264@4k the issue, the system should be fine until you try to do temporal denoise or use neatvideo

Walter,

Hello all, I'm hoping someone can help me out

If this is an accurate description of what's going on, then I have to believe that there is a problem. Resolve should not crash when you add 4K 100mbps H.264 media to the Media Pool. And you should not get an out of GPU memory error message with an 8Gig video card playing out 4K H.264 on a 1080p timeline with no effects nor should that card should be at 100% utilization.

Maybe the files are actually H.265 instead of H.264?

The files are definitely H.264 and all the rest of the information is accurate. I'm pretty knowledgeable about computers, just learning about resolve and video editing and all that goes with it. I came to the same conclusion you have, that something else is going on. I was hoping it might just be a issue that I'm using the free version and it's limitations are causing this and upgrading to studio will resolve it. Thanks for your help.

@PeterMoretti didn't get that far, in my case was apparently an intermittent fault with the physical connection to the 2nd GPU (after cleaning the contacts on the GPU and riser/ribbon cable with a rubber eraser, and blowing out any dust, it seems fine).

Other things I can think of are:
Check that you're running the latest version of Resolve.
Check that you're running the latest video card drivers.
Check your GPU settings inside Resolve. I've attached a copy of mine; you can also try CUDA or OpenCL instead of Auto.
Try making new projects and see if this always happens.
Run only one video card and be certain it is in the correct slot.
Physically remove the video cards and check their contacts (like Dean experienced).
Uninstall/reinstall Resolve.
Make a cell phone video of this happening and post it for the BMD team to see.
After a crash or out of memory error, post a file sharing link to a DaVincie Resolve log file. You create a diagnostic log by running the following program: C:\Program Files\Blackmagic Design\DaVinci Resolve\CaptureLogs.bat

Off the top of my head, these are the steps I would go through. And I've used some variety of them quite a few times when trying to figure out what's going with my setup.

Also, it's entirely possible that the paid version will fix your problem, just by virtue of doing a new install of the program. But I have to say that what you are reporting with the free version is not normal, IMHO.

Good luck!!
