RADEON RX 580 DUAL 8GBX2 MINING COMPUTE ACCELERATOR, BULK PACK, PCIE X1
Notes from Sapphire
The maximum GPU support depends on the number of PCI-Express x16 slots available on the motherboard.
For example if the motherboard has 2 x PCI-E x 16 slots available, it could support 2 units of this SKU (which contains 2x RX580), total 4x (RX580) GPUs.
There is no special manual available for this SKU from Sapphire but please note the following:
1) This GPU is passively cooled – Sapphire suggests that installer should test the motherboard to ensure the system has adequate airflow
2) This GPU has no display output. The installer has to set the default display to the integrated graphics chip on the motherboard when installing and using the GPU.
