nVidia 1080 ti

[savage309]

That NVlink sounds like something to wait for. I wonder if it'll be backwards compatible, or it'll need a new kind of card.

Beside the software support (which we already have in V-Ray GPU) it needs additional hardware, which at the moment is available only in Quadro GP100.

Asus release three different 1080Ti :
GTX1080TI-FE : https://www.asus.com/Graphics-Cards/GTX1080TI-FE/
TURBO-GTX1080TI-11G : https://www.asus.com/Graphics-Cards/...GTX1080TI-11G/
ROG-STRIX-GTX1080TI-O11G-GAMING : https://www.asus.com/Graphics-Cards/...I-O11G-GAMING/

When we compare, apparently, no real hardware difference :
1x fan for the Founders Edition.
1x fan too for TURBO Edition but it's dual-ball Bearing Fan (less noise?)
and finally,
3x fans for ROG-GAMING edition, higher and wider than the others (2.5-Slot Width)

but no overclocking ?

OC'ing should accompany the 1080 ti...I read tests done at 2 GHz in order to get the 30-35% advantage over the 1080. I don't know if I would spend the $ if I couldn't OC them.

overclocking just introduces more problems for graphic cards so better to stay at stock, especially when you have issues with the card and need to send it back, they can deny fixing it

Depends on the brand. Usually EVGA will be glad to take OC damaged card. I think its even in ther RMA TOS that u can send OC damaged hardware.

OCing GPU for rendering is a lot different to OCing gpu for gaming. If u OC for rendering u don't have too much to worry about - at least last I checked. You can also hit higher OC than for games if u just will render it. < might be wrong but last time I tested I could get a lot more out of my GPU when I only used it for rendering and not games.

actually there i think your wrong, rendering i think pushes gpus to the limit while games not so much, tried with the most punishing game benchmarks, highest settings etc gpu temps hardly move and the clock speeds are usually ok, when rendering however temps go up higher as well and the clock speeds and if your planning to overclock better have cooling, good cooling, at stock you can render and have no issues once your gpus arent close but once you plan to overclock you better be cooling which costs

MIT, have you tried one of those amfeltec splitter/clusters? I'm wondering if they would work on a regular MB and 28 lane cpu. My thinking, leave a card in the MB for the display running at 8x, and use a splitter/cluster in another slot adding 4 cards running at 4x. I've read guys using these on high end mb's, but I'm wondering if the high MB is necessary just for 5-6 card WS.

no never heard of these until now, gona look into it

Hey MIT, did you have to do anything special to get those usb risers to work? I'm testing one, I have one card in the 16x MB slot, and another card in the riser...windows 7 reports errors with riser card. I've tried two different risers and two different cards in the riser, also tried a different slot...same thing. Windows doesn't like the riser card.

no i didnt do anything special, you have the 60 cm usb 3 risers? let me see which one, also make sure you update your graphics drivers, for me i had to do nothing special just worked

I have been waiting for Virtual GPU technology to really happen. Is this even a reality?

I forgot to plug in power to the card...I powered the adapter and the card's fans came on, windows detected and loaded the driver but reported a problem...once I realized I forgot to power the card, it worked.

I'm dumb!

It's for virtualised desktops, Nvidia and AMD both have their own technology in this field. Started with Nvidia creating their own cards with keplar (not too different from the Tesla cards, but with drivers optimised to partition the GPU between virtual machines), haven't herd anything on pascal though. All in all it's not efficient and a very expensive way of providing gpu resources to a virtual machine, if your aim is to run vray. You would be much better off using the cloud resources from Amazon, Microsoft or more conveniently a render farm.
