ASUS ROG Strix Radeon RX 6900 XT LC

This graphics card pairs an AMD Radeon RX 6900 XT GPU with a factory-fitted hybrid liquid cooler. The 16GB GDDR6 frame buffer runs across a 256-bit bus at 16 Gbps while the boost clock reaches 2365 MHz. It targets enthusiasts who want high frame rates at 4K without building a custom loop.

PCIe 4.0 slot 850W PSU three 8-pin connectors

Your motherboard must provide a PCI Express 4.0 x16 slot for full bandwidth. A power supply rated at 850W is recommended to feed the three 8-pin connectors. The 240mm radiator and 600mm tubing need space in the case for front, top or side mounting. Verify clearance for the card length and the blower-style VRM fan airflow path.

4K gamers multi-monitor creators not SFF builders

The HDMI 2.1 and two DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320 resolution with HDCP 2.3. DirectX 12 Ultimate and OpenGL 4.6 cover modern APIs and CrossFireX support for DirectX 12 and Vulkan. Small-form-factor cases that cannot accommodate a 240mm radiator should consider an air-cooled alternative.

Questions about this item

Does the box include the 240mm radiator and 600mm tubing, or must I buy a separate water-cooling kit?

The card ships with a full-coverage cold plate, integrated 240mm radiator and 600mm tubing already assembled, so no extra liquid-cooling parts are required.

The specs list a 2365 MHz boost clock and 16 Gbps memory — which version should I pick for 4K gaming?

This single SKU already runs at the factory-overclocked 2365 MHz boost with 16 Gbps GDDR6, giving the highest out-of-the-box clocks available on the RX 6900 XT.

What does the 2365 MHz boost clock actually deliver once the card is installed in a PCIe 4.0 system?

In a PCIe 4.0 slot with an 850W supply and three 8-pin connectors, the GPU sustains its 2365 MHz boost under load thanks to the hybrid cooler keeping the die and memory at lower temperatures.
