Help! PrPro 5.5.2 and nVidia 285.62 on GTX 285
davidbeisner2010 Jan 6, 2012 12:16 PMOk, I had posted about this about a month ago over in the main forum, and thought I had solved the problem, but it's back. Unfortunately I can't find my original post to resurrect it, as Jive seems to have wiped my post history beyond two weeks ago... :-(
Anyway, I bought PrPro 5.5 to work with RED Epic footage, and installed it alongside my 5.0.3 on Win 7x64 Ultimate. I ran all updates (5.5.2), and then on my first startup got the message that I wouldn't have CUDA support since there was no CUDA enabled card installed. I knew that wasn't right cause I used CUDA all the time in 5.0.3, so I checked and found my drivers were significantly out of date. I updated my nVidia drivers from nVidia's site, rebooted, and relaunched PrPro. Everything worked great. Until I had to export my first video. During export I consistently got an nVidia driver error, saying that my system resources didn't match what was required by the program (something about it couldn't get small enough packages for the video card to process), and it had to close. Closing the nVidia driver error box also force quit PrPro. I discovered that by running without CUDA I had no issues and could successfully export my video. However, I can't afford the time to run without CUDA as it significantly speeds up the processing time, especially with multiple layers of Epic footage.
So ultimately I did a complete wipe and reinstall of the entire system, starting with the most recent non-beta drivers available for the nVidia card, and put only 5.5 on the system and fully updated to 5.5.2. It recognized my CUDA card and there were no issues. I've worked off and on (very light work over Christmas) until today when I dug back into my big Epic project and started doing some basic scaling and speed adjustments on some clips, and some primary CC with the RGB CC and Three-Way CC. I frequently get the same nVidia error message that I had gotten before I did the wipe and re-install, and it's killing my workflow and productivity. I turned CUDA back off again this afternoon to get this one timeline finished and exported, but I really need it back.
What changed about CUDA support between 5.0.3 and 5.5.2 that has screwed things up with my GTX 285? And what do I need to do to fix things and get them back up and running? Before the wipe and reinstall I had tried multiple versions of the nVidia drivers, incluidng rolling back as far as I could go and keep CUDA support, and the new beta drivers that Ann and others had recommended. Unfortunately purchasing a newer graphics card probably isn't an option since I've already spent over $2300 in the last couple months on hardware and software upgrades.
As a refresher, my other system specs are as follows:
Intel Core i7-920 2.67GHz (no overclock)
12GB RAM
250GB SATA OS/Programs
500GB SATA Graphics/Pictures/Other stuff/Pagefile
3-disk SATA RAID-5 2TB Video Project Files
4-disk SATA RAID-5 8TB Video Data Files (PCIe RAID card)
1TB SATA Video Export/Encore Project files
4TB eSATA Data Backup (not currently in use)
400GB eSATA Project Backup (not currently in use)
