Ready for CrossFire and VR

The MSI Radeon RX Vega 56 Air Boost 8G OC is built around the AMD Radeon RX Vega 56 chipset with 8GB of 2048-bit HBM2 memory. It targets serious gaming and graphic design workloads while also supporting casual computing and light gaming. CrossFire bridging is not required for up to four cards, and the board is validated for VR headsets.

Thermal and power profile

A fan-and-heatsink cooler handles heat in normal operation across base clocks of 1181 MHz and boost clocks of 1520 MHz. The card draws supplementary power through two 8-pin PCI-E connectors and fits a PCI Express 3.0 x16 slot. Physical size is 10.63 by 4.33 by 1.57 inches at 2.35 lbs, which determines case clearance and airflow planning.

Bundled software and media

The MSI Gaming App provides direct control over performance profiles and onboard LED lighting. AMD FreeSync synchronises display refresh rates for smoother motion, while AMD Eyefinity expands the field of view across multiple monitors. A driver CD is included for initial setup without an internet connection.

Questions about this item

How do I install the card in a PCI Express 3.0 x16 slot and connect the two 8-pin power cables?

Seat the card firmly in the PCI Express 3.0 x16 slot until the retention clip clicks, then attach both 8-pin PCI-E power cables from the PSU; the step most often missed is plugging in the second 8-pin connector, which the card requires for stable operation.

What maintenance will the Air Boost cooler need over time?

The dual-fan heatsink uses Military-Class (MIL-STD-810G) components; periodically remove dust from the fins and fan blades with compressed air to maintain airflow and thermal performance.

What thermal or power limit appears first during extended heavy loads?

With a 1520 MHz boost clock and two 8-pin power connectors, the power limit is typically reached before the thermal ceiling, causing the GPU to throttle clocks to stay within its power budget.
