1. The motherboard must support PCIe Bifurcation, which splits a single PCIe x16 slot into multiple channels. For example, to divide into four PCIe x4 lanes (x4/x4/x4/x4) to support four NVMe SSDs.
2. The combination of your motherboard and CPU must provide enough PCIe lanes to support all PCIe devices installed on the motherboard (including M.2 NVMe SSDs in M.2 slots).
3. The PCIe slot you use for installing the MB308A5 must have enough PCIe lanes and be correctly configured with PCIe Bifurcation.

Key Tip: The availability of PCIe lanes depends on your motherboard and CPU specifications, as well as how many PCIe SSDs and other devices you have installed. Therefore, we cannot guarantee compatibility with the MB308A5 based solely on a compatibility list. We strongly recommend consulting your motherboard supplier to confirm how many PCIe lanes are available in your system and whether any remaining empty PCIe slots can fully support the MB308A5 with four NVMe SSDs.

If you're unable to obtain this information from your motherboard supplier, you can follow the steps below to verify compatibility yourself (applies to Asus, ASRock, and AORUS motherboards only).

Step 1: Open the motherboard compatibility list and locate your motherboard model.

Step 2: Once you find your motherboard model, check the PCIe slot that can support the MB308A5 based on the CPU you are using. You need a PCIe slot that supports 4(x4+x4+x4+x4) to detect four NVMe SSDs. If your PCIEX16_1 slot is already occupied by another PCIe device, such as a GPU or RAID card, then PCIEX16_2 and PCIEX16_3 will only be able to utilize the remaining PCIe lanes. Refer to the PCIe lanes distribution for different configurations to identify the appropriate PCIe slot based on your motherboard model, CPU type, and current PCIe slot usage, and find the slot where you can install the MB308A5. The example below uses the ASUS AMD CROSSHAIR VII HERO to help you better understand how to use this compatibility list.

Example:
For the ASUS AMD CROSSHAIR VII HERO, if you are using AMD Ryzen 1000 Series/ 2000 Series/ 3000 Series/5000 Series Processors CPUs, the PCIEX16_1 slot on the motherboard can support the MB308A5 and works four NVMe SSDs. However, if you are using an AMD Ryzen™ 5000 G-Series/ 4000 G-Series processors CPUs, the PCIEX16_1 slot on the motherboard can only works three NVMe SSDs in the MB308A5. For AMD Ryzen 2000 G-Series/ 3000 G-Series/ 7th Generation A-Series/ Athlon X4 Series processors CPUs, the PCIEX16_1 slot on the motherboard can only works two NVMe SSDs in the MB308A5.

Important Notes:

1. The method to check compatibility with Intel motherboards follows the same steps as the AMD example above.
2. PCIe slots share PCIe lanes, and the PCIe Bifurcation mode varies based on the PCIe slot's position. Not all empty PCIe slots have enough lanes for the MB308A5. If you have already installed devices such as GPUs, RAID, or HBA adapter cards, please check whether the remaining PCIe slots can support the MB308A5.
3. If the motherboard’s CMOS battery (coin cell battery) is low on power, the BIOS may revert to default settings after a power loss or system reboot. If the PCIe slot used by the MB308A5 was previously manually configured for bifurcation, this setting may be lost, reverting the slot to single-lane (x16) mode. As a result, the system may only detect one SSD. To ensure all SSDs in the MB308A5 are consistently recognized, we recommend periodically checking and replacing the CMOS battery to maintain the required bifurcation configuration over time..
