I’m getting the exact same results as Vladimir. Running 7.1.2 on a 12-core 2.66, except I have a 5770 for the gui and a Cubix with 2 Quadro 4000s in it. Odd. Resolve reports 2 GPUs in the “about” screen.

Resolve 7.1
4 nodes – 24fps
5 nodes – 20fps
6 nodes – 17fps

Hi all,

Do you get higher frame rate if you set Proxy Mode to On ?

Hi Everyone,

Cubix Engineering has run benchmark tests with 1-4 x Quadro 4000 for Mac on GPU-Xpander Desktop 2, Desktop 4, and Rackmount 8 models. I’ll ask my engineering department to forward this information to me, or post it directly to this thread if helpful.

Thanks to this test I discovered that I was getting reduced performance from the host adapter connected to the Cubix. Reseating all the cards and connectors, I can now get 6 nodes at 24fps, 7 at 20. This is with a Desktop Pro 2 and 2xQuadro 4000.

Eric, would I get more with the Desktop Pro 4? Do I understand correctly the Pro 2 slots have x8 electrical and the Pro 4 x16?

[Eric Fiegehen]

Hi Adam,

GPU-Xpander Pro2 / Desktop 2 was limited to 40Gbps on 4-slot configurations, even with PCIe x16 HIC (Host Interface Card) connections to Mac Pro’s x16 slot. Desktop 4, with the Cubix part numbers referenced by DaVinci with the release of Resolve 8, natively supports 80Gbps bandwidth. This same 80Gbps 4-slot PCIe backplane is also used with the GPU-Xpander Rackmount 8 model (2 of them in a 4U rackmount enclosure).

When installing the hardware, keep in mind that PCIe connections can be sensitive to bumps and jostling. One of the first support procedures we ask customers to perform is to reseat the 3rd party I/O cards, the Cubix HIC, etc.,. This solves 90%+ of the PCIe link questions we receive when customers are installing equipment.

I’ll have Cubix’s Technical Support Manager, Mic Grover, add any additional tips to this forum once he returns next week from his vacation in the South Pacific (lucky bastard!).

David Catt,

Which Mac OS X version are you using?

After setting the playback speed to 100fps to get a better overview for the lower nodes;

“2 nodes” – 61fps
“4 nodes” – 40fps
“6 nodes” – 29fps
“12 nodes” – 16fps

“NR4” – 48fps
“NR3” – 32fps
“NR2” – 16fps
“NR1” – 5fps

This is on a Hackintosh with Nvidia GTX (OC) 480 for GUI, GTX 285 for GUI, Decklink HD Extreme 3D, i7@3.8GHz on X58 mobo with 6GB RAM and reading media from a 4 drive RAID0 that has 540MB/s I/O.

With this test I get 24 fps with 7 nodes which I am more than happy with, anything over 7 nodes and I’ll use the render caching.

Can’t wait to see single GTX 580 results if anyone gets that working!

Future system will be Dual-GPU (hopefully dual 580 on LGA2011 board).

All we need now is better processing for cheap real-time half-red RED debayering! I’m getting a 6-core soon and hoping to go to 4.2 GHz which might get me close! Will keep you guys posted.

p.s. LOVING 8.01 (-:

Hi Sascha

the file is expired, why not upload to your website?

[Colin Travers]

Hey Sascha,

Any chance you can re-post this project so i can do a comparison between my 285 and the 470 i just got?
cheers
