HighPoint 4x 10Gb/s Ports PCIe 3.0 x4 Gen 2 USB 3.1 Host Bus Adapter

While using unraid was expecting 4 seperate iommu groups, got only 2 with shared bandwith.

My OS is Windows 8.1 64. I need to use this card to access a shared drive on my PC with other computers on my network. My shared drives are 4Tb each; both plugged into a docking station. During my initial install of the card, Windows did not install the correct drivers for the chip-set on the card. I had to search for the correct drivers: ASMedia xHCI Host Controller Driver 1.16.45.1. Once I downloaded the drivers, it was still tricky to get them installed as they are not "signed" through Microsoft. Therefore, you have to override the default and allow the driver to be installed. I had to use a manual install process which was described in a ReadMe.txt file included with the drivers. Then, you MUST make sure your device, in my case, the docking station was USB 3.1 Gen 2 compatible. Finally, you have to make sure that all of the cables and hubs between your device and the card are also USB 3.2 Gen 2. If you are successful in accomplishing all of the above, you will be satisfied with your new card. For me, it represented quite a few upgrades and purchases. With all of that said, you should be happy with your purchase because the speed is a big reward. This whole process in not for those who are not dedicated to achieving the end result of 10 Gb/sec. It takes time patience and understanding of the technologies involved. It is unfortunate that the drivers are not "signed" through Microsoft. It is also unfortunate that High Point does not ship the drivers with the card; they should along with the appropriate instructions for the install as well as a detailed explanation on the proper selection of peripherals and cabling. I still think that the card is the best out there at this time. I have purchased two of these cards. Both arrived from Amazon later than promised.

Simply install and it works. not the cheapest, but the performance is excellent.

To my surprise when I opened the box, the seal on the static plastic bag containing the card was broken and can clearly see marks on the golden pins and finger print near one of the USB ports.I pay full price for a NEW product and NOT and USED or OPEN BOX one.Very Lame

Four discrete channels of USB 3.1 are just what the doctor ordered to stop the hiccups I was experiencing in VR. I've got two sensors, the oculus and a head tracking camera attached to the same card and because it has four independent channels everything works perfectly. No usb bottleneck and no conflicts with any other device. Fantastic!
