Sli/PCI lane gpu question
Posted: Mon Mar 09, 2015 1:45 pm
Hello! let me bring you up to speed quickly>>>
I want to render with octane in my 3d programs This is listed in the FAQ section of Octane
"Can Octane Render use multiple GPUs?
Yes! Octane Render completely relies on the GPU for rendering performance and scales extremely well. If your motherboard can accept more than one video card, adding additional video cards will greatly improve Octane's rendering speed because Octane's performance scales perfectly with the number of GPUs (e.g. rendering with four GTX Titans will be 4x faster than using only 1 GTX Titan), without the need for SLI. The cards can be different models, allowing GPUs from two completely different architectures to be used in a machine with multiple PCI-E slots (such as a GTX 560 in the primary slot and a GTX 780 in the second)."
SO
I have a asus mars gtx 760x2... does that mean since it's a dual card single slot that it's only using 16pci lanes?
My cpu is a 5820k, 28 pci lanes. I know I can sli x 2 or x 3 (16x, 8x) (8x,8x,8x) and I understand that the 8x bandwidth is more than enough to handle what the card can actually do in gen 3 pci
But is my dual gpu card using 16x, 8x or just 16x when in a single slot??
I want to know this because I might just plop in a gtx 980 later on when the price goes down..as I don't play games and Octane claims any gpu any architecture.
And more importantly..... will that be a good card for Octane? It's hard to see a lot of people rendering with it.
