I'm having trouble getting the 2nd card to run SLI. I worked on it all day yesterday and can't get my system to see the 2nd card. After I initially installed it and powered my system back on, as soon as Windows loaded, an Nvidia driver was downloaded immediately, it was the 3D driver which I didn't have installed. So this makes me think my system recognizes the card, it's just not operating correctly. Also, on the Asus Maximus VI Formula MB, PCIe slot 1 is run at 16x when using a single card. When running 2 cards, PCIe slots 1 & 2 will run at 8x. Currently, with my older card working and the other one installed, but not working, it says PCIe slot 1 is running at 8x. I worked on this all day yesterday, but at some point today, I'm hoping to try running the new card by itself in slot 1 so I can be certain I don't have a dead card. It's going to be difficult because my original card is watercooled and tied into my loop. I was hoping to get the 2nd card to operate in SLI before ordering my waterblock and everything. Off 1 780Ti, which I have clocked at 1300, I can run the 4K monitor with my DP and the 1080P at its native resolution with no problem. I can only run the 4K with the 2K if I lower the resolution on the 2K or reduce the color sampling to 16 bits from 32 bits, and this is with the 2K hooked up via DVI-D. It has a DP connector, and I'm hoping to run it off the DP of the 2nd card if possible. Also, my 4K monitor has dual tuners so I can hook it up via DP & HDMI at the same time and the signal coming into the HDMI can be run in PIP or I can split the screen in half and run 2 separate screens on the same monitor, but of course I haven't even tried doing this yet. Also, if I reduce the resolution and/or the color depth on the 2K monitor, then I can run all 3 monitors. I just can't do this at their native resolution. I'm going to try working on this a little more today and hopefully I can either get everything working or at least narrow down what the problem is.

Ok, an update and a question. I bought my 2nd card, but the EVGA part number is slightly different, by 1 number, from my current GPU because it has the ATX cooling system on the card, which I'm taking off and throwing in the garbage anyway. (By the way, after looking at reference cards and non-reference cards with no blower, fans, heatsink, etc installed "naked," I realized the card I already have is a reference card. I could tell because of the layout of the VRMs, GPU, etc with all the "cool looking stuff" removed, and comparing the two side-by-side, the reference card vs non-reference have different chip layouts (PCB ), hence, NVIDIA reference). Well, I was about to order an EK waterblock for my 2nd 780 Ti, same place I bought my first one because I get a discount, but there were some additional parts I'mnot familiar with since this is my 1st SLI configuration. They had an EK terminal bridge block, some that run in Dual Parallel, Dual Serial, Dual Parallel 3 Slot, and Dual Serial 3 Slot, and I'm not quite sure what I need or what the difference is between the parallel and the serial bridge block. Also, my original card came with an SLI connector, which I know hooks the 2 cards together, but what exactly is the terminal bridge block, what's the difference between the parallel and the serial? I just want to be able to maximize my GPU performance is one better than another or is it even a necessity? I'd like to know what the difference is and which one I should buy. Also, are all SLI connectors the same or is there a different one, besides the one that came with my card, that might help the 2 cards perform better? Any input would be greatly appreciated since my card will be here any day and I haven't ordered my waterblock yet. I'd appreciate any input since my card will be here on Monday, and I haven't ordered my waterblock yet or the backplate since I need to know what else I need so I'm not constantly ordering pieces here and there to complete my build. Lastly, will the pump I have be enough to run this extra loop through a second GPU or do I need to upgrade my pump or add a second pump? Right now I'm using a Laing D5 & Swiftech MCP-655 Alphacool VPP Single Edition Pump with an EK D5 X-Top Acetal Pump Top. It's running through a 360 rad, VRM waterblock on the MB, CPU waterblock, Z87 chipset waterblock, 480 rad, 780 Ti (about to be 2), and then back to the res. My flow meter shows plenty of flow rate, but I just want to make sure the 2nd GPU isn't going to be too much.

Yea, my 2560 monitor is an IPS monitor, but I'd like to be able to run it simultaneously with my 4K monitor. I work from home, and I really need multiple monitors when I'm working but if I need to run only one of them when gaming then that's fine with me. I just want to be able to utilize all my monitors in a work environment. I've already bought my 2nd 780 Ti Superclocked card, the exact card I already have. Since there's really no benefit to getting a card that might be able to overclock more than the one I have, getting the exact same card may make everything run more stable. I guess it's time to order my EK waterblock.

Yea, I'm guessing my 4K monitor takes more power than I thought. I've got it hooked up through my displayport and my 1920x1080 monitor hooked up via HDMI, but when I hook my 2560 monitor up using the DVI port nothing comes up on any of my screens. If I just hook up the 4K monitor and the 2560 monitor, the 4K monitor looks fine, but the 2560 monitor isn't even legible. I guess I could go into the settings and lower the resolutions to see if I can get a clear picture on each, but that defeats the purpose of having a 4K monitor. At least it would tell me everything is fine and I just need more power to run all of them at full resolution. I just bought an Nvidia Shield Tablet which works kinda cool streaming Assassin's Creed or Watch Dogs from my PC to wherever I am, but doing this only utilizes one monitor since the Shield is basically a mirror image of the monitor when using the Nvidia Hub and Game streaming. It's nice to be able to build a fire outside, sit by it, and play Assassin's Creed, or basically any game on my PC or on Steam. All the games on the Nvidia Grid can be played for free, but I don't think they're going to be free starting around May. So, do you think buying a 2nd card would solve my problems? Like I mentioned earlier, I read up on running an SLI configuration as much as I could since I've never really had to run SLI until 4K came along, but I wasn't sure if I needed to get the exact same card (same part number). It sounds like as long as it's a 780 Ti chipset it should work fine with what I have. I'm just not looking forward to taking apart my loop to add another. Is there someone who sells a stock 780 Ti without a blower, heatsink, etc since I'm just going to be taking that off anyway?

Ok, I'm running a Corsair AX1200i Digital ATX 80 Plus Platinum PSU, Asus Maximus VI Formula ROG Z87 MB with EK Asus Maximus VI Formula Liquid Cooling Nickel+Acetal Block Set (swapped out the original Cross Chill since it's made with aluminum and installed a Z87 chipset waterblock), Intel i7-4770K Haswell OC'd to 4.5Ghz with a Koolance 380I waterblock, 16GB G.SKILL Trident X 2133 DDR3 (which run horribly. G.SKILL has already agreed to swap them out. The XMP OC profiles lock my system Gaming up and same happens when I manually set the timings), Asus ROG Front Base & Overclocking Panel, (and as you already know) EVGA GeForce GTX 780 Ti Superclocked (then OC'D a little more) 3GB with full EK Nickel+Acetal waterblock and backplate, 2 Samsung 840 Pro 256GB SSDs running in RAID0, Seagate 2TB Hybrid drive (holds all my data files), Hitachi 1TB 7200RPM SATA III drive, Lamptron CM615 6 channel liquid cooling controller, Asus 12x Blu-ray burner, EK-Multi Option Res X3 250, EK D5 X-Top Acetal Pump Top CSQ - Laing D5 & Swiftech MCP-650/655 Alphacool VPP Single Edition Pump, EK Ultimate Performance Coolstream 480 XTX and 360 XTX radiators, 8 Cougar 120mm CFD Series Fans and 2 Cougar 140mm CFD Series Fans, Koolance INS-FM19 Coolant Flow Meter w/ flow meter frequency adapter all housed in a Little Devil PC-V8 case. I've been running 3 monitors, a 27" HP ZR2740w IPS running at 2560x1440 and 10 bit color and 2 23" HP 2311x running at 1920x1080. I've been running these monitors until recently, when I bought a 4K monitor and swapped it with one of my 1920x1080 monitors. Now, if I try running these 3 monitors nothing even comes up on my display. I can run the 4K and the 1920x1080 with no problem. If I try running the 4K and the 2560x1440 monitor, I can't even make out the text on the 2560 monitor. I would like to run all 3 monitors and possibly even the one I replaced (4 monitors total). I figured the only way I was going to be able to do this is to buy a 2nd card, maybe a third, and run them in SLI. I thought about replacing my 780Ti, but the card is still a nice card and I can pickup some second hand cards from people who upgraded already for half the price I paid for mine brand new. So, if anyone has any suggestions, I would really appreciate it. Let me know if you think upgrading would be better or adding another card. I think it's going to be a while before the 980Ti hits the market.

I've had this card for about 6 months or so, but I need to run a second card in SLI and would like to know what the best card is on the market that will run SLI with my current card. I've heard, and read on Nvidia's website, that the brand of card doesn't matter. As long as it's a 780 Ti, it should run SLI with my current card. What I would like to know is if any particular manufacturer makes a better card that the EVGA Superclocked, and when Nvidia mentioned that the model GPU is the only determining factor about SLI compatibility, does this mean even a 780 Ti Classified will run SLI with my Superclocked card as well? I've never run, or setup an SLI configuration, but since quite a few models have been released since I bought my card, I know it's just a matter of time before the 780 Ti will need to be replaced. So, I want to buy whatever manufacturer, whatever version of the 780 Ti will run the best and still be compatible with the card I have when running SLI. Should I stick to the exact make, model, part number (03G-P4-2883-KR) as my current card or would anyone recommend another manufacturer besides EVGA or even a different model 780 Ti made by EVGA? I want to get the best performance possible, but I also don't want problems when running SLI. Any suggestions anyone might have would be greatly appreciated. Oh, one more thing, I took the heat sinks, fans, etc off my current card and installed a full EK waterblock along with the backplate so I would probably doing the same with this second card. Hopefully someone will be able to make this easier for me since I want to get this done asap.
