ASUS GeForce RTX 4090 ROG STRIX OC

The ASUS GeForce RTX 4090 ROG STRIX OC is a manufacturer-refurbished graphics card built for enthusiasts who need maximum frame rates at 4K resolution. It arrives tested and confirmed fully functional by ASUS with only minor cosmetic signs of use. The card ships in an anti-static bag inside a plain box bearing an ASUS refurbished label. No accessories, manuals or driver discs are included in the package.

PCI Express 4.0 x16 interface

This card requires a motherboard with a PCI Express 4.0 x16 slot to operate at its intended bandwidth. The interface determines whether the GPU can communicate with the rest of the system without bottlenecking. Builders using older platforms limited to PCI Express 3.0 will see reduced throughput. Verify your motherboard specification before purchasing to ensure compatibility.

24GB GDDR6X memory capacity

The 24GB GDDR6X frame buffer handles large texture packs, high-resolution assets and complex compute workloads without paging to system memory. It comfortably drives multi-monitor setups and VR applications at maximum quality settings. Workloads that exceed 24GB of video memory will spill over to slower system RAM, causing noticeable performance drops.

Questions about this item

How does the 24 GB of GDDR6X memory perform once the card is installed?

The 24 GB GDDR6X frame buffer lets the RTX 4090 hold very large textures and datasets, so 4K and 8K workloads run without swapping to system RAM.

What does the PCIe 4.0 x16 interface actually limit in everyday use?

The x16 link provides full bandwidth for the GPU, so the interface does not bottleneck gaming or compute tasks on a compatible motherboard.

What physical space and bracket does the ROG STRIX OC need to fit in a case?

The card uses a full-height bracket and occupies multiple expansion slots; verify your chassis has enough length and clearance for a thick three-slot design.
