Corsair's "Vengeance (2 x 32GB, 4800 MHz, DDR5 RAM, SO-DIMM)" RAM, with product code "CMSX64GX5M2A4800C40", is not specifically listed as compatible with the Minisforum UM690 Venus Series in the available sources.

However, here are some points to consider:
- The Minisforum UM690 Venus Series supports 4800MHz DDR5 memory in dual-channel configuration, which matches the Corsair Vengeance memory specification.
- Compatibility often depends on the compatibility of the mother system and the exact specifications of the system.

To confirm compatibility, it is recommended that you check the specifications of the Minisforum UM690's mother system and consult the manufacturer's documentation or contact Minisforum or Corsair technical support.
