AMD FirePro W4100 Graphics Card - Low Profile Graphic Cards 100-505979

Works on a Linux 4.8.12 kernel. The stock radeon kernel driver identifies it as "Cape Verde GL [FirePro W4100]." X.org server also autoconfigures it, and the displays it finds connected. It had no trouble with two 4k monitors (3840x2160). Beware that deep in the fine print of the AMD datasheet, it says it cannot actually drive all four outputs at 4k 60Hz. Says it can do three monitors at 4k/60Hz, or all four at 4k/30Hz. Have not tested these setups.It does include the audio over Displayport device. This also just works with no configuration on Linux 4.8.12, which sees it as "Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]." For some reason not the AMD datasheets, nor the marketing web pages, nor any description anywhere mentions this feature. Whereas the extremely similar "Visiontek Radeon HD 7750 eye4" advertises this on the box and everywhere else.If you are also looking at the Visiontek Radeon HD 7750 eye4, it's almost exactly the same thing. According to chip specs, the Radeon HD 7750 core speed is slightly faster at 800MHz, where the Firepro W4100 runs at 630MHz. That's all. There is no detectable difference between them when driving two 4k monitors.

I have used AMD video cards for many years, but have never had one crash as often as this one does. Crash reports have been sent to AMD for several months now, and nothing has been done to address this issue. At first it was happening once over a 2-week period. Now it is crashing more frequently and more recently 3 crashes same day. There is nothing specifically happening at the time of crash (could be web browsing, watching a video, using a MS Office product, etc.) - no rhyme or reason.Very disappointed.

If you want to support lots of displays with a small, energy efficient card this is the most economical choice as of late 2016. You can support up to 6 displays using one active DisplayPort expander and power consumption is good. Be careful to maintain good airflow and a cool environment though, the heatsink solution isn't incredibly robust. I've seen disregarding this lead to premature hardware failure. The 3D acceleration on this card is very basic. This is not a gaming card.

Could never get the pc to post with this card in the pcie slot

Well they should tell you that if you are trying to drive 4 monitors lets say DP (Display Port) to HDMI you cant get 4 DP to HDMI Cables because that setup will only light up two monitors, you need to use two DP to HDMI cables plus two DP to DVI adapters then two dvi cables for it to light up all 4 monitors, If you monitors support DP then all 4 monitors will work with DP to DP cables. So I wasted hours and it cost me more money and a trip back out to the customers sight have to go back make me look bad.

I purchased this card to power 2 2K and a 4K monitor, it installed into a PCI Express 2.1 slot perfectly and is powering my monitors without any problem. Despite being actively cooled with a fan it is a very quiet card. It can power up to 4 monitors including up to 3 4K monitors at 60hz.

this card works fine, but appears to have some driver issues with Windows 10.

This is one of the nicest things I get for my current project, runs great and stable, at the beginning we found some issues but after updating the drivers all issues disappear, don't forget to update and enjoy, really flexible and easy to operate and control.
