InLine 76660N Internal M.2 Interface Card PCIe Male 64 Gbit/s

The InLine 76660N is an internal PCI Express expansion card that provides two internal NVMe M.2 slots for parallel operation of two NVMe SSDs. With a PCIe 3.0 x8 interface and Hyper M.2 technology for automatic lane configuration, the card delivers up to 64 Gb/s total bandwidth and supports transfer rates of up to 4 GB/s per M.2 slot. Onboard LEDs indicate read/write activity, and the card is natively supported by Windows and Linux without additional drivers.

Advantages

This InLine PCIe card supports two NVMe M.2 SSDs simultaneously while preserving full PCIe bandwidth, uses Hyper M.2 for automatic detection of lane configuration at boot, and provides LED indicators for easy status and fault diagnosis. It draws power for the M.2 modules directly from the PCIe bus and requires no extra drivers, ensuring straightforward integration into supported systems.

Suitable for

• Upgrading desktops with high-speed NVMe storage
• Systems that require two internal M.2 NVMe SSDs operating in parallel
• Workstations and servers with a free PCIe 3.0 x8 (or x16) slot and BIOS/UEFI that supports PCIe bifurcation

Key specifications

• Bus type & PCIe: PCIe 3.0 (8 GT/s) x8 lanes — up to 64 Gb/s total bandwidth
• Interfaces: 2 × M.2 Key M slots (NVMe)
• Chipset: PI6C20400BLE
• Supported M.2 sizes: 2230, 2242, 2260, 2280, 22110
• Data rate: Up to 4 GB/s per slot
• Dimensions: 135 mm × 68 mm (PCIe board)
• Operating temperature: -40 °C to +85 °C
• Operating systems: Windows 11, 10, 8, 7; Windows Server 2012 R2; Native Linux (Fedora, SUSE, Ubuntu, Red Hat)

How to use

Install the InLine 76660N into a free PCIe 3.0 x8 (or x16) slot on the motherboard and secure it with the supplied bracket and screws. Insert NVMe M.2 SSDs into the two M.2 Key M slots and fasten them using the included screws and thermal pads as required. If your motherboard requires PCIe bifurcation for simultaneous operation of both M.2 devices, enable the appropriate bifurcation or lane-splitting option in the BIOS/UEFI (check the motherboard manual for the exact setting). After installation, boot the system; the card uses Hyper M.2 technology to detect lane configuration automatically and the OS should recognize the drives without additional drivers.

Usage recommendations

For optimal performance when running two NVMe SSDs in parallel, ensure your motherboard supports PCIe bifurcation and that the target slot is configured (e.g., x8 → two x4 channels) in BIOS/UEFI. Verify compatibility with your NVMe drives and consult the mainboard manual if both SSDs are not detected.
