DaVinci Resolve Lite on maxed iMac 2009
I understand the 2009 and 2010 iMacs are not officially supported but I’d like to try to learn the product doing some minimal work at least. The iMac is a quad-core i7 2.8 GHz, has 16 GB RAM, 512 MB video RAM on an ATI Radeon 4850 (which Resolve reports as a NVIDIA Radeon 4850).
I have created the Sample Project and Saved it as a new project. But I can’t get to work on the clips in the “Sample Project” without getting an error message related to CUDA algorithms failed, possibly GPU memory exhausted, and suggests I reduce concurrent correctors. I reduce the correctors to one only after exposing all the correctors. Still no go. Seem to be in a catch-22 because I cannot save the Default Project so Resolve Lite will load with only the Colour Corrector active. It insists on creating a “Copy of Default Project” which I imagine isn’t going to help me.
Any way I can get this one and a half year ‘old’ piece of junk to work with Resolve short of buying a new iMac? Thanks for your help.

I uninstalled and reinstalled from the .dmg created yesterday. The uninstall didn’t remove the Resolve database since the reinstalled version came up with yesterday’s database. Any idea how to find and get rid of the database? Regardless, all behaviour was identical to yesterday. Still getting GPU algorithm failure. I tried adding a folder in Finder with my own clips (.mov files) and when I tried to add that folder to the media clips, it appeared to do nothing.
Kim, do you also get the NVIDIA pop-up telling you the NVIDIA driver needs upgrading? I can’t help but feel that’s related to my problem as I didn’t think it would look for NVIDIA on a system with ATI 4850. Do you get a warning when launching the application that an NVIDIA Radeon 4850 was detected?
Thanks for any response.

I saw from your other post, that you are running on Snow Leopard 10.6 whereas I’m running on Lion. I wonder if that’s the problem?
Thanks for any response.

Kim, thanks for your comments. I completely reinstalled Snow Leopard 10.6.8 on an external drive, installed Resolve Lite there and had the same results! The sample video and my own test video (both H.264) do not display correctly and I keep receiving the error message “Error in GPU algorithm, probably exhausted memory…” which I now based on your results is not true (assuming you also have 512 MB of video memory on your graphics card in your iMac. I’m at a loss now as I’ve tried everything. I know the configuration manual recommends Snow Leopard 10.6.7 but surely it works under 10.6.8. I’ll give Blackmagic a call or e-mail them.

Kim, I see in a later thread about corrupt graphics, that Rohit Gupta says my ATI 4850 series cards in the late 2009 iMacs have issues with OpenCL – now that makes sense then and leaves me high and dry. Certainly was news to me, how disappointing that Apple hasn’t fixed this via firmware. I’ll check AMD’s site for an update. You must have a mid-2010 iMac if you have the i3 chip and I suspect you have the ATI Radeon 5670 GPU – wise choice!

“Kim, not sure which upgrade if any on my machine did the trick but the new DaVinci Resolve Lite 8.1 now appears to work flawlessly on my iMac 2009 with ATI Radeon 4850 GPU running Lion 10.7.2. Still get a warning to use the 5770 and higher GPUs but everything I tried works now.

my machine is the mid 2010 with the 5670…i only found out by checking the specs. it wasn’t a deliberate decision as i just walked into the shop and said i wanted an iMac with 4gigs of ram and the fastest cpu at the time. lucky indeed! glad to here that 8.1 works for you. i’m still sitting on the fence with resolve. there are so many things that i think still need work. i keep join back to color for speed and compatibility. its just so quick and easy for me. send to color, grade, render, send back to fcp..super simple.
