Hi Tom's Hardwarers! I am working on fine-tuning my PC setup for gaming performance and have a few questions concerning GPU and my displays.
1. First, I am trying to configure my 4 monitors so that 3 can run in landscape together with NVidia Surround @ 60Hz, and the 4th monitor runs separately @ 144Hz. Is this going to be possible with my GTX 780 or is my card simply not powerful enough?
It seems as though my monitor connection capabilities change when I reconfigure which monitor gets which cable connection. I have:
3X - ASUS VE248Q (DisplayPort/HDMI Inputs) 60 Hz monitors
1X - ASUS VG248QE 144 Hz monitor (DP/HDMI/DVI Inputs)
I assume 144 Hz only runs through Dual Link DVI since I could not produce that speed though DisplayPort or HDMI cables(I have both the latest versions of these cables, Just purchased). When I swapped my monitors out and added my 3rd VE248Q through a DVI to HDMI adapter(assumed the adapter wouldn't matter since the monitor only runs @ 60Hz anyway). What configuration would I need to be able to produce this setup?
2. My card is the GTX 780 Classified running on air. I have it clocked at 1280(+165Mhz) with 3308Mhz (+303Mhz) on my memory. I am using GTX Classified Controller for my voltage control(1.212Volts on NVVDD, 1.62 Volts on FBVDD, and running 312Khz on PWM Freq.) and MSI AfterBurner for my overclocking. I was using precisionX but I had a lot of problems with my card randomly clocking itself down to 531 Mhz for no apparent reason. So now I am using AB, but I am noticing some screen flickering randomly. It happens usually on one monitor at a time, but I seem to notice it on my 144Hz monitor the most and usually when my card is running at idle speed(888Mhz). I am running LN2 with the Skyn3t Rev3 flashed. My GPU is 80.80.21.01.80, should I be using only the REV3 or should I use the REV4? When I started noticing the screen flickers I went ahead and reinstalled my drivers and it was good for a couple days but then started doing it again. I notice that while the card is fully clocked up to 1280 and under load during games that the flickering does not occur. Any thoughts on this? Do I need more voltage? Also, would going up to a more stable Platinum rated PSU from my Bronze help? Or is my card simply not powerful enough to run these 4 monitors? This leads to my last question.
3. I was planning on running a second card in SLI mode, currently building savings. I am using a 1000W PSU and plan on going to a 1200 Watt Platinum. Is this a sufficient upgrade? I might want a 3rd card in SLI as well(I would have to drop to x8 speeds on my PCIe slots though so I am not sure if it's worth it). Will 2x GTX 780 Classifieds run better than a 780ti overclocked? If I run 2 of them on air I will probably keep the clocks around 1202, I do however plan on putting them both on EK blocks and giving them each their own custom loop and radiators. Will I be able to power 5760x1080P @ 144Hz with 2 of these cards in SLI? Would I just use all the DVI outputs from both cards?
Sorry for the long post, I like to get technical and include as many details as I can to hopefully paint the picture well enough. I love talking tech so any helpful comments would be awesome! Thanks folks! Much appreciated!
