PNY NVIDIA NVS 810 Graphics Cards for DVI VCNVS810DVI-PB

Upgraded from a VisionTek Radeon 7750 2GB GDDR5 6M (6x MiniDP) to go from 6 monitors to 8. Works great.

Awesome product.

Update:I received a replacement card from Amazon and the new card works perfectly. I can confirm that the previous card was defective. I will update my rating if it passes a six month working test.Original Review:After failing to install this graphic card on a PCIe 2.0 Supermicro server motherboard (no signal on any of my monitors), I was able to make it work inside a HP Z800 workstation running on 64bit version of Windows 7 (also PCIe 2.0). Everything seemed to be working fine for exactly two weeks, Occasionally, three of my seven monitors would lose signal and restart, but I was not bothered as long as they came back. Today my workstation froze requiring a restart. Upon restart, all my screens were pixelated (see image) and the signal was being refreshed continuously. I uninstalled the graphics driver in Safe Mode and reinstalled the latest drivers from the NVIDIA website to no avail. I also removed the graphic card and reseated it in a different PCIe slot but that did not help either. The NVIDIA support was not able to provide any solution and since the card was still within the return window I decided to request a replacement. This was my first NVIDIA card and I'm hoping I received a defective card. I have never had issues with my AMD GPUs including a W4100 which I tried to replace with this card.

Could only run 2 4k monitors and was dropping frame rate in a hurry. Upgrade to the AMD Firepro 9100. Much better if trying to run more than 4 4k monitors at once. The 9100 runs my 5 4k monitors with ease a 60hz+. This PNY card really should be reserved for signage where frame rate doesn't matter. Probably a great cheap option for that!

good choice for research! thank you pny!

Card runs great under Linux(Fedora 25). Shows up as a dual GPU configuration, so half of the ports will be disabled when you first start up. If you install the nvidia driver you can manually enable them. To use as one giant display try using "SLI Mosaic" mode as referenced here:[...] MosaicPerformance is amazing and runs smoothly. Can't recommend it enough.

I was trying to use this card with 8 screens for digital signage - under Linux (manual claims that Linux is supported OS). 4 out of 8 monitors would not work with drivers provided by NVidia. Tried 4 different versions of the driver - it just would not see 4 monitors.End-up removing the nvidia drivers and using opensource version that comes with Linux. Can't say it works perfectly (randomly freezes), but at least it shows something.W600 by AMD is way better for my application, even though AMD drivers are not working, but at least open source version seems to be very stable.Thanks.
