  • Supports booting from attached NVMe drives for flexible system startup
  • Works with Windows, Windows Server and Linux without driver installation

Expanded Oculink Connectivity

The LetLinkSo LLS-CD-1PC2OC-01 adds two Oculink SFF-8612 x4 ports through a single PCIe 4.0 x8 slot, giving desktop builders a direct path to external NVMe storage or eGPU enclosures that use SFF-8611 cables. It targets users whose motherboards lack native Oculink headers but have a free x8 electrical slot. Buyers who need more than two ports or who only have x4 or x1 slots available cannot use this card.

Welded Connector Construction

Each Oculink housing is welded to the PCB rather than surface-mounted, which reduces flex during repeated cable insertion and removal. The x8 edge connector splits into two independent x4 links, so each port can run at the full PCIe 4.0 16 GT/s per lane rate without sharing bandwidth. Systems without bifurcation support in the BIOS will not see both ports simultaneously.

Boot Support And Driver-Free Operation

The adapter presents attached NVMe drives as bootable devices, allowing the operating system to load directly from external storage without an internal drive. No proprietary drivers are required; Windows, Windows Server and Linux all recognise the card natively on insertion. The package contains only the adapter board itself, so SFF-8611 cables and any mounting brackets must be sourced separately.

Questions about this item

What PCIe standard and lane count does the LLS-CD-1PC2OC-01 use, and what total bandwidth does that provide?

The card uses PCIe 4.0 across eight lanes at 16 GT/s per lane, delivering 128 Gbps total throughput.

What physical slot and bracket space does this dual Oculink SFF-8612 adapter require?

It needs a PCIe x8 or larger slot and occupies one low-profile bracket opening for the two SFF-8612 ports.

How is the card installed, and which step do builders often miss?

Insert the card into the slot, secure the bracket screw, attach SFF-8611 cables to the SFF-8612 ports, then verify the motherboard BIOS sets the slot to PCIe 4.0 x8 mode — many leave it on auto and get reduced width.
