PCIe 5.0 x16 to PCIe 5.0 x8 Split Card Dual M. 2 MKey 4.0 SSD Adapter Supports x8x4x4 Bifurcation Compatible with M. 2 NVMe 2230 - 22110 SSD Product Description The Card is designed for users who need to maximise the utility of a single PCIe x16 slot. It splits the slot into one physical x16 connector (electrically x8 at PCIe 5.0 ) and two M. 2 MKey sockets (PCIe 4.0 x4 each), letting you install a graphics card and two NVMe-compatible SSDs in a compact space without replacing your motherboard.
Critical BIOS Bifurcation Setting: This adapter relies on your motherboards PCIe bifurcation feature. To unlock full performance, set the target slot to x8x4x4 in BIOS.
If your board only offers: x8x8 Only the PCIe x8 slot and the rearside M. 2 (SSD1) are active. x4x4x4x4 The PCIe slot will run at x4 speed, but both M. 2 drives will work. No bifurcation Only the PCIe x8 slot is usable.
Physical Design & Thermal Support: The PCB uses a 6layer, goldimmersion construction with highquality connectors to minimise signal loss at Gen5 frequencies. The M. 2 slots accommodate up to 22110 length drives, giving you flexibility for enterprisegrade SSDs. The PCIe slot is a standard x16 connector but operates at x8 lanes physically fits any x16 card.
Performance Caveats: The PCIe slot is Gen5 x8 enough bandwidth for even the fastest currentgen GPUs. The M. 2 slots are Gen4 x4 they do not support PCIe 5.0 NVMe-compatible SSDs (they will not work). Using a PCIe riser cable may degrade the signal to Gen4 or Gen3 and can cause instability; for best results, plug the card directly into the motherboard.
