Feature: 1. PROFESSIONAL DESIGN: PCI Express 4X riser card for high frequency impedance PCB board design. High accuracy machine soldered 4 layer PCB with gold plating for stable transmission. No jumper setting. No driver software program required. 2. SUPERIOR PERFORMANCE: PCI Express 4X riser card has the best conductivity and excellent electrical performance. Resistance to plucking and plugging. Ensure the signal is stable at full speed without attenuation. 3. WIDELY APPLICABLE: PCI Express 4X riser card 90 degree adapter card is best suited for graphic design, gaming or watching videos. No dropped frames at all. 4. USEFUL ACCESSORIES: The PCI Express 4X Riser Card keeps the PCI Express card away from the motherboard and the PCI Express sockets directly aligned with the sockets on the motherboard. It is a right angle lifting board for the PCI Express X4 bus. 5. INSTALLATION: The connectors are soldered to the component side (B side) of the board. When the I O board is inserted, the component side of the I O board will face down toward the motherboard. 6. COMPATIBILITY: The PCI Express 4X Riser card does not support hot swapping. PCIE devices can be freely installed according to the location and size of 1U and 2U servers. Specification: Item Type: PCI Express 4X Riser Card Material: PCB Interface: PCI Express 4X.
