    For Iray, the Vram / cards do not need to be the same -  Nvidia state not to use SLI for rendering so it won't matter for doing this type of work

    I think but am not sure that cards only need to be identical to run in SLI for gaming but as I only have 1 card & don't game, its not something I have thought about.

    850W is probably enough to run both cards but there are people that post here daily that know a lot about building PC's & would know better about power supply & the type of cooling required to run 2 cards without killing the PC so maybe one of them will chime in with a definate answer :)

    Thank you. I use computers. I'm not great with Specs and what not. I figure 850 Watt, not because I wanted two cards. It's just that from what I understand its better to be over, then under powered.

    If I can use both cards for iray that would be awesome. I love my 1070. Dont get me wrong. It's a great card. I have no issues with it at all. One of the best cards I've ever owned, really. But I still wanna cut my render times... If I can cut them to 4 minutes instead of 20. That would be great. Most of my renders are 1200 x 1500 and cook in about 25 mins. Not bad times. But I hate having my card maxed out like that for long periods of times. The less time it spends rendering, the longer life span I will have. Does that make sense?

    A little bit. But IMO the life span of these cards isn't going to be influenced to a degree that you would ever notice. I've never had any video card burn out due to excessive usage, besides it's not like you're rendering 24/7. Heavy gamers are probably going to task these cards way more and still I've never heard of lifespan being an issue. That's not even mentioning that in a few years you're probably gonna want to stick in the new fancy 1280 Ti with 36GB memory, twice the speed plus integrated AI that tells you funny jokes and uses the air of your laughter to help power the card.

    hehe... Are you that card? Trying to make me laugh? It worked :)

    Fair points. I just dont know what the future holds for me. If I can even upgrade again when its needed. I do game though. When I'm not rendering and making art, I like to load up steam and get online and cruise around town in GTA5 with a couple friends.I'm not a heavy gamer but I do play them from time to time.

    Matter of fact. One of my favorite things to do with 3D Art is make fan art of some of my favorite games. =D

    I know I'm going to get Flack for "No Mans Sky" hehehe, but its a great game that I can enjoy with the kids without feeling guilty.

    anywho! Yeah, if I can use my 1070 for extra VRAM ontop of the 1080. That would be neat. But I'm sure theres a wrong way and right way of doing it... Hopefully someone can clear the air on that. I'm also a dumby... I never noticed I have 4 open slots on my Motherboard. I can put 32 more gigs of Ram in this puppy if I wanted to hehe. I have 4x8GB DDR4. and 4 free slots. That will be next move I suppose. It's only $300ish to put my Rig at 64GB of DDR4 Ram. Maybe I'll do that after new years.

    @Angel - Wings - You do some beautiful renders and I recognize your style instantly, Kids are hard to render and look realistic but yours do :)

    The Vram on the 1070 does not add to the 1080TI - If your scene fits into both cards then both cards will be used - if your scene is taking 9Gb Vram then the 1070 will be dropped & the 1080 TI will do the render.

    My motherboard is already maxed out at 32GB Ram & I don't have the slots, cooling or power to run 2 cards but I never keep a computer long so my next one will have more bells & whistles - I usually give my old PC to my hubbie as we both work online so need reliable computers but he is not doing anything that requires all this extra stuff so this time I am going to take my 1080 out & keep it so he will need a new GPU to :)

    Do let us know how you get on with your new set up as it will give me a clue as to what I want in a new PC

    Yeah sure thing. I'll do some benchys with my rig. Post stats. I'll make sure its a scene anyone can make with the basic stater kits provided by Daz and then share the scene file. Anyone should be able to load it. Mind you it will be a real test. 4 People, Fully Clothed. With a complex lighting system. No HDRI. Thats cheating on a benchmark IMHO. That way they can gauge for themselves if its worth the upgrade. Some have people have 980's Ti 6GB... Some have Geforce GTX 1070's Some people have the Titan... I'll have the GeForce GTX 1080 Ti 11GB.

    Hey some of us are using CPU Power. hehe! I know I was for 3 years. I have the Patience of an Angel - Pun intended xD

     

    Any anyone who wants me to render their own scene for a test. Provided we own the same things I'll run their scene on my card and show them.

    Call me cazy but I just couldnt resist... I ordered 4x8GB DDR4 Sticks. hehe

    I dont think GTX1070 is going to do a whole lot for me. I'll probably just sell it. If anyone wants to buy it from me. Hit me up in my PM box. Maybe we can strike a deal.

    It's only a year old. It's still runs great.

    Unless something has changed, the card with the least VRAM will "cripple" the other card. Like the GTX 1070 has 8gb and the 1080ti has 11gb. If your scene runs over 8gb vram, it will kick the render to CPU. Reason why I am only running my 1070 and not both my 1070 and 1060 for more cuda cores.

    No, it has always been the case that GPUs will be dropped as they run out of RAM without affecting other GPUs with more RAM. There have been reports, slightly mixed, of a slow card slowing a fast card but not of memory limits affecting other cards.

    So how do I set that up exactly, to get the most out of both cards?

    My new card will be here today in the mail. I'm bouncing up and down in my chair and watching every car that passes by the house. hehehehe

    Oh one other dumb question. I bought an SSD. It's 1TB I dont want to clone my drive I want a totaly new system on my SSD. I have a windows 10 Disk. Umm... Little confoozed on how I would treat the SSD in this situation. I didnt build my computer. I'm not tec sabby like that. I really have no idea what I'm doing with Drives if they dont plug into a USB port, hehe. It's kinda like cars. I know how to drive one. I'm a good driver but I couldnt tell you how to replace the Alternator.

    I did the same 2 days ago :) Actually it is an easy process. When the manufacturer already mounted the SSD to the case everything is connected properly. 
    If not, you might need an adapter mount for 2.5" drives to fit in the 3.5" slot if the case does not have such slots. 
    Then just connect it like every other SATA drive. The connectors are the same like for any other usual HDD. Also the power cable is the same. 
    SSDs are jumperless like any modern HDD. 

    If you have another non SSD drive too just install Windows to the SSD, that's it. 

    In my case I had a running Wndows and needed to transfer it to the SSD. 
    I used EaseUs Free version for it. It went smoothly and can be done in the live system and when you use the system clone feature also the first small partition with the boadloader gets cloned. This is important. 

    Then I just changed the boot drive in the Bios and Windows booted from the SSD. The "old" boot drive appeared as usual drive. Check if everything works then you can delete the old partition and use it as data drive or whatever. 

    I was surprised how easy the migration process was. 

    Instead of mounting the SSD for the migration you can also use an USB SATA adapter. But I did not see reason for that since the SSD goes into the case anyway. 

    In your case, when you want to install everything new, just bootup your PC from the Windows DVD and install it to the SSD, you can select the drive in the process. You might need to delete the existing system partition before in the case Windows tells you you have a system installed already and wants to repair that one. 

    If the SSD is your only Drive, the installation is just the usual way.

    I can only suggest the GTX1080 TI Strix Edition with 11 GB Memory. It is not cheap but it is a beast. Renders are soooo fast and even big scenes load fine into GPU Ram.

    Thank you. I went ahead and got it. I'm not seeing any benchmarks for my card. I guess I will be the one adding the first 1080 Ti 11G bench lol...

    That benchmark thread shows that a 1070 gets around 3 minutes on the benchmark scene (and that's about what I get with my 1070), and a 1080ti got around 2 minutes. Though there can be some variation in how people do the benchmarks, so I figure the numbers are more of a ballpark and not necessarily exact. But I kinda expect a 1080ti to cut a 1070 render time almost in half. 

    BTW, some might say that the benchmark scene is too small to accurately predict render times with larger scenes, but other posts with huge scenes seem to support the same results obtained in this benchmark. 

    Also, here's the summary I made of results of many of the render times in that benchmark thread. I tend to assume the results are +/- 15 seconds or so.

    Yeah I'm not getting those times. I'm wondering if I'm not using my card to its fullest or something.

    Does great on Games 90-330 FPS. But on the rendering it dont feel much different then the 1070.

    Oh Nevermind... I didnt have OptiX Accelleration turned on. Duh... lol! Now were hitting those benches. I know its only 96 but I wanted to capture it live. It finished at 100% only a few short seconds later. This is on Factory settings, which I think is 1526Mhz

    So it did cut my time in half... My 1070 was wrapping up this scene in about 4 minutes.

    Angel - Wings Glad you got everything working - 

    Hopefully next year , when I am due a new machine a GTX1080 TI Strix Edition (or two) as suggested by SF-Design will be mine but for now the ordinary 1080 does enough so I can't justify spending more right now unless we win the Lottery :)

    K, so now for the real test. I loaded the last render I made. This one is indoor, with Sky-Dome sunlight, and multiple indoor lights covered by lamp shades and ceiling light covers with a strong DOF with lots of hair. I figure if there was going to be a good test of power this is a great render to try it on. With my GTX 1070 the render time was about 55 minutes. With my new card it was cooked up 30 minutes with 1.2k Iteration Which was actually more samples then my orginal. In a sprint race, its Aprox 125% faster off the line, then the GTX 1070. In an endurance race, its Apox 80% faster then a GTX 1070.

    I feel the same. Next year they'll probably have GTX 1280 Ti's with 16GB VRAM... lol

    At the rate things are improving, I'm probably not wrong... :D

    Hehe yeah, I just bought it when it was kinda new but it will get cheaper for sure :)

    I was using two 980TI's in SLI and decided to replace them with two 1080TI's.  Then I remembered that I have a 3rd PCI express slot on my motherboard so I kept one of my 980TI's as a third card.

    I pulled up a scene that I had done earlier with my 980TI SLI system.  I rendered 2000 samples at 4K resolution with a 98% convergance ratio in 1 hour and 6 minutes.  I just ran it again with my new setup and it took 33 minutes.  Literally twice the speed of my last setup!  This was everything I had hoped for.  The number of cuda cores went from 5600 to 10000 which is not double what I had before but the new cuda cores are indeed larger and faster than the ones in the 980TI. 

    I downloaded the latest version of DAZ as soon as I installed my new cards and everything worked perfectly first try.  I am very happy with the DAZ support and the Nvidia performance.

    Here is a pic of my new setup.

     

    Very nice.  Certainly in my to do list.  Now, I was under the impression that the cards will render faster NOT in SLI.  I would try disabling SLI and seeing if there is a difference.

I would try disabling SLI and seeing if there is a difference.  It's easily done using the Nvidia control panel.

    If you decide to keep the GTX 1070 as a secondary card to help in renders.  Go in to your Nvidia Control pannel PhysX settings and set the 1070 to a dedicated PhysX card.  Doing this will drop the idle VRAM usage on it down to 80MB freeing up more VRAM for Rendering.

  • Any recent update on iRay and GTX 1080Ti?

    I replaced a faulty Titan X and it worked fine for a few days then the DP/HDI ports ceased to function leaving me with only DVI and single monitor.  I had same problem with Titan thus this replacement.  Zotac will repair or refund but still begs question why two nVidia cards in a row ceased to have DP output.  Also the basic driver does not support iRay so use the "studio version" driver which does.

    I am now back to one monitor.  Ugh.  Since I use KVM this is a pain because I need two ports one of which adapted to VGA to accomodate KVM ports.

    My last ditch is to buy an ultra wide monitor and ditch dual monitors.  ( That creates different problems if you click full screen anything such as Shift-F11 in viewport will hid the tool's panel rendering that reature useless.

    Thoughts? Ideas?
