  • 20 mm spaced Gen4 connectors accept extension cables
  • Gold fingers thickened to 5U for reliable contact
  • CPU 4-pin power port plus LED status indicator

PCI-E 4.0 x16 bifurcation card

This Vszerda expansion card splits a single PCI-E 4.0 x16 slot into two x8 electrical links. It is intended for builders whose motherboard BIOS supports x8x8 bifurcation and who need to run two devices from one full-length slot. The card carries a clock-splitting IC and a power-on LED indicator. A CPU 4-pin auxiliary power port is included with a 20mm cable.

Installation requirements and common issues

The motherboard must allow the PCI-E operating mode to be changed to x8x8 in BIOS; without that setting the card will not function as intended. Gold fingers use a 5U thickness for reliable contact and the Gen 4 connectors include dust plugs and locking snaps. The two slots are spaced 20mm apart, so clearance between adjacent cards is fixed at that distance.

Practical limits of the PCI-E 4.0 x16 interface

Total bandwidth remains that of a single PCI-E 4.0 x16 link shared across the two x8 connections. Devices requiring a full x16 electrical link cannot operate at their maximum potential on this card. The bifurcation is transparent to the operating system but depends entirely on motherboard chipset and BIOS support for x8x8 splitting.

Questions about this item

How can I confirm the split card is operating at PCIe 4.0 x8 per slot after installation?

Verify the motherboard BIOS shows the PCIe slot running in x8x8 bifurcation mode and check that the power-on LED on the card is illuminated.

What cables and accessories are included with the Vszerda PCIe split card?

The card comes with a 20 mm spaced dual-slot bracket, a 4-pin CPU power cable for the auxiliary CPU4P port, and dust plugs for the Gen4 connectors.

Which version of this bifurcation card should I choose for a motherboard that only supports PCIe 3.0?

The card is backward compatible with PCIe 3.0, so the same PCIe 4.0 x16 to x8x8 model works on both Gen3 and Gen4 platforms.
