using multiple GPUS with Asus X99 Deluxe
hi, instead of getting a cubix to install 2 GTX titan 6GB in to boost things up for davinci resolve on my old MacPro early 2009, im thinking to get the Asus X99 Deluxe. in its specs page. i read that you can install 3 GPUs with speed 16x 16x 8x
would davinci work fine if i used the 2 pcie slots with 16x for the 2 GTX Titan i have for image processing. and installed another gtx in the 8x slot for GUI?
anyone tried that? would it work fine when it comes to noise reducion?
thanks

Regardless of the manufacturer of the board, you have to make sure you have enough slots for other cards as well.
That is where the Cubix shines.
My z820 has a Kona3, a thunderbolt card, a Blackmagic Card, a Quadro k4000 , an esata card and a cubix card.Also be very careful when reading the specs. Many mother boards are 16x on this slot, as long as that slot doesn’t have a card in it, or that card doesn’t have a 16 x card in it. you need to carefully map out your cards, ensure they will all work together, (and don’t take up 2 slots)
You may need 2 Cpus to get the full bandwidth on all the slots as well (if the board has that ability)
Other cards will only work in specific slots, and Blackmagic has its own recommended slot configurations.

Both Windows and Mac versions of Resolve are limited to two GPUs… If you want to use more GPUs you’ll have to switch to the Linux version of Resolve. At least that used to be the case…

2 plus 1 for your gui. (studio version)
I dont think that has changed in 12.5

from osx 10.9.2 there is a 2 nvidia gpu limit till then its 4 on yosemite, isn’t it? resolve limits the gpus to four or five (regardless of osx or win?) if i remember correctly?

Not sure about Mac. I run windows. I have 2 +1 for gui. Seems to me i had a discussion a year or two back with Peter where the question was if the gpu limit number included the gui card…whether ir not you used it for compute (if that is still an option). The answer was that number is for the total number if cards in your box. For windows i thought it was 3.

peter, or someone else from bmd, can you clarify how many gpus are supported in dr12.5?
windows and osx? -
It doesn’t really work with that motherboard to have 3 GPUs, as you’ll need one slot for Decklink card. With X99-E WS it’s theoretically possible, but practically not really. But 2 Titans is possible, just forget the GUI card. Or, have just one Titan/GTX 1080 and another card for GUI.

you mean use the 2 titan i have with deluxe? or with the X99 E MB? cause as i noticed it could be the best option since it has 4 PCIE runing at x16
maybe 2 titan is good option since i already have them , and i dont think i need more for 2k workflow, right?
