The cable is passive, so the link speed is negotiated between the host and the drive. A Gen4 board with Gen4 drives trains at 16 GT\/s; a Gen5 drive on a Gen4 board simply runs at Gen4. Nothing needs to be configured.\u003c\/p\u003e\n\n\u003ch3\u003eDo I have to enable PCIe bifurcation?\u003c\/h3\u003e\n\u003cp\u003eIt depends on how your board wires the MCIO port. Many server boards ship the MCIO 8x header already configured as 2 × x4, or drive it from a PCIe switch, in which case there is nothing to change. If your board exposes that header as a single x8 root port, enable x4x4 bifurcation for that port in the BIOS. The board manual will state which case applies.\u003c\/p\u003e\n\n\u003ch3\u003eDo the U.2 drives need their own power cable?\u003c\/h3\u003e\n\u003cp\u003eNo separate SATA or Molex run to each drive — power is delivered through the integrated lead in this assembly. You connect that lead to the system PSU once, and both U.2 connectors are powered from it.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between MCIO and SlimSAS?\u003c\/h3\u003e\n\u003cp\u003eBoth are compact internal PCIe connectors with 8-lane (74-pin) variants, but they are different standards with different housings and latches, and they are not interchangeable. MCIO is SFF-TA-1016 and is the connector most PCIe 5.0 server boards use for NVMe breakout. SlimSAS is SFF-8654 and is also used for SAS 4.0. If you are unsure which one is on your board, send us a photo of the header and we will confirm.\u003c\/p\u003e\n\n\u003ch3\u003eCan I connect SAS or SATA drives to this cable?\u003c\/h3\u003e\n\u003cp\u003eNo. The MCIO 8x port carries PCIe lanes only, so the device side must be a U.2 NVMe drive or a U.2 NVMe backplane. For SAS drives, use a SlimSAS to SAS fan-out cable instead.\u003c\/p\u003e\n\n\u003ch3\u003eWill it work in a Dell, HPE or Lenovo server?\u003c\/h3\u003e\n\u003cp\u003eOften not, unless the system uses the standard SFF-TA-1016 pinout. Several OEMs re-purpose the same physical connector with a proprietary lane order, and a standard cable will either not link or will link at reduced width. Tell us the exact model before ordering and we will check it against our pinout notes.\u003c\/p\u003e\n\n\u003ch3\u003eIs 80 cm too long for PCIe 5.0?\u003c\/h3\u003e\n\u003cp\u003eAt 32 GT\/s every centimetre adds insertion loss, so keep the run as short as your chassis allows and avoid tight bends or sharp folds. 80 cm is intended for in-chassis routing to a rear cage.

If your drives and board are Gen5, use the \u003ca href=\"https:\/\/diliving.com\/products\/mcio-x8-to-2x-u-2-nvme-adapter-sff-ta-1016-gen5-80cm\"\u003eMCIO to 2× U.2 version\u003c\/a\u003e, which is rated for 32 GT\/s.\u003c\/p\u003e\n\n\u003ch3\u003eWhy use SFF-8643 at all instead of going straight to U.2?\u003c\/h3\u003e\n\u003cp\u003eBecause the hardware you already own decides it. A Gen4 x4 NVMe link delivers the same 7.88 GB\/s whether it passes through a U.2 connector or an SFF-8643 connector — the connector is not the bottleneck. If your backplane or drive cage is SFF-8643, this cable is the cheaper answer than replacing the cage.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need to enable PCIe bifurcation?\u003c\/h3\u003e\n\u003cp\u003eOnly if your board wires the MCIO 8x header as a single x8 root port. Many server boards ship that header already split as 2 × x4, or drive it from a PCIe switch, in which case no setting is needed. Check the board manual for that specific header.\u003c\/p\u003e\n\n\u003ch3\u003eCan I connect SAS drives to the SFF-8643 ends?\u003c\/h3\u003e\n\u003cp\u003eNo. The connector type alone does not decide the protocol — the host port does, and MCIO carries PCIe lanes only. Put a SAS drive behind this cable and it will not be detected. For SAS, use a SlimSAS to SAS cable with an HBA that speaks SAS.\u003c\/p\u003e\n\n\u003ch3\u003eBoth ports at full speed, or do they share bandwidth?\u003c\/h3\u003e\n\u003cp\u003eBoth are full x4 links. The eight host lanes are physically split 4 + 4, so each port has its own four lanes. There is no bridge chip and no shared uplink.\u003c\/p\u003e\n\n\u003ch3\u003eWill it work with a U.2 adapter that has an SFF-8643 input?\u003c\/h3\u003e\n\u003cp\u003eYes — that is one of the main uses. The adapter converts the 4-lane link to an SFF-8639 drive connector; the cable only has to deliver four clean PCIe lanes to it, which it does at Gen4 rates.\u003c\/p\u003e\n\n\u003ch3\u003eIs 80 cm safe at Gen4 speed?\u003c\/h3\u003e\n\u003cp\u003eYes, Gen4 (16 GT\/s) tolerates this length on a well-built passive assembly. Keep the run as direct as possible, avoid sharp folds, and do not coil excess cable tightly against power rails.\u003c\/p\u003e\n\n\u003ch2\u003eIn the box\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × MCIO 8x to 2 × MiniSAS HD cable, 80 cm (RMC74-8690-AX1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBacked by a 24-month warranty.
