![]() The other point to this debate is the lack of ECC VRAM on the GTX 780 / consumer card. Remember that the GTX Titan was also a similar chip (GK110- 400) but had the "Titan driver" to unlock FP64 performance. However, I mention this because this is still common practice (soft limit performance) to keep workstation cards at a higher price. Ultimately, it was better to leave the card as a 780. I hoped it would improve performance in 3D rendering based applications but I was wrong. I don't recall if we modified the vBIOS but I do recall the system read the card as a Tesla/Quadro. NVIDIA Quadro K6000 Specs - FP64 (double) performance 1.732 TFLOPS (1:3).NVIDIA GeForce GTX 780 Specs - FP64 (double) performance 173.2 GFLOPS (1:24).NVIDIA Tesla K20c Specs - FP64 (double) performance1,175 GFLOPS (1:3).Which theoretically unlocked FP64 performance. It altered how the card read itself and we were able to install a driver to make the system believe it was a Tesla K20 but it may have been a Quadro (k6000). It's been a while so I don't recall the details. With that card, my brother used a graphite pencil and I believe connected two resistors. Headless works, but is a significant downgrade in usability.Īlso enabling ECC cost me about 5% game performance so I turned it off. Newer windows 20h1, 20h2 should do a decent job of assigning the appropriate gpu for the task and you can override w10s gpu choice if you right click to display settings then scroll down to graphics settings and select your program or app to override. You also lose normal nvida control panel functionality with no attached display.īut I see you have an igpu so you could just plug your video out cable into your mobo and see what it would be like to run a headless 3090 in no time flat. These limitations are very hardware specific and results can vary a bunch even with different monitors. No tearing, no stutters, just that I have to deal with the limitations of all of the links in the chain. I'm running a tesla m40 through an intel igpu and, just for an example of the mysteries you will encounter, I'm running it at 1440p57. Click to expand.Neat to try, but many headaches.
