We have a Resolve 10 reference rig (i understand that this was bought from davinci/blackmagic) with the following configuration:
Motherboard X8DTH-IF
2 x Intel Xeon E5500
32 Gb DDR Registered ECC RAM
Geforce Quadro FX 5800 (for cuda)
Geforce Quadro 4800 (for gui)
Decklink 4K
Intel 10Gbps NIC (igxgb)
Power Supply is 760w
OS is Centos 5.4
Nvidia Driver 319.49
Davinci Resolve 10.1
The framestore is a NAS on a 10Gbps with according to frametest is able to handle realtime R/W up to 4K.
This system is capable of rendering 15 FPS and full speed playback
We bought a GFX Titan card thinking on improving the render speed, but unfortunately when we install it the actual render performance goes down the drain to less than 5 FPS and playback speed suffers as well.
I'm at odds about what could be causing this performance drop.
Best guesses so far are:
- Lack of Power supply oomph
- PCIe x8 slot (motherboard has physical 16x connectors but they are only 8x electrically)
- CPU Bottleneck
Any help will be greatly appreciated.
