How to view the indicator lights on the product?

D1 represents the 12V power supply of the adapter card, D2 represents the 3.3V power supply of the adapter card. During computer use, D1 and D2 are normally on; The D3 light is the CLKREQ # indicator light, which remains on during normal use of the adapter card; D4 is the RESET # indicator light, which flashes when the computer is turned on or off and is turned off during normal use; D5 is the hard disk read-write light for Slot1, D6 is the hard disk read-write light for Slot2. When the hard disk is in read-write state, the indicator light will flash.

What is the function of the switch on the product?

Five years ago, some old graphics cards did not support the CLKREQ signal. If the CLKREQ signal light did not light up, you could simply toggle the micro switch to 2 without entering the BIOS for settings, which improved compatibility and convenience.

Why can only one disk be recognized after splitting the motherboard settings?

Please first check if the motherboard split is set to x8x4x4 or GPU With M.2 Storage. Once set, you can use the adapter card for full functionality; If the BIOS is set to x4x4x4 or RAID mode, the PCIe expansion slot can only recognize x4, and both SSDs can recognize it; If the BIOS is set to x8x8, the PCIe expansion slot can recognize x8, but only one SSD can be recognized. It is recommended to install the SSD in Slot 1 at this time. Secondly, please confirm whether the slot where the adapter card is located supports PCIe x16 full bandwidth operation. Please refer to the motherboard manual for details.

How to confirm whether the motherboard supports Bifurcation PCIE split?
Please check your motherboard manual, manual or BIOS option will explain Bandwidth PCIE channel splitting or Bifurcation option. If not mentioned then not supported, option please choose 4x4 or x4x4x4x4
