MSI GeForce GTX 1080 Ti Duke 11G OC graphics card

SKU CH-44KQ-4NF71

11GB GDDR5X graphics card with a 352-bit bus, 3584 stream processors, 1531 MHz base and 1645 MHz boost clocks, plus two DisplayPort, two HDMI and one DVI-D output for four monitors

  • 11 GB GDDR5X memory with 352-bit bus for high-resolution textures
  • Boost clock of 1645 MHz delivers strong frame rates in demanding titles
  • 3584 stream processors handle complex shading workloads efficiently
  • PCI Express 3.0 x16 interface provides ample bandwidth for modern systems
  • Four display outputs support up to four monitors simultaneously

11GB 352-Bit GDDR5X GPU for 4K Gaming

The MSI GeForce GTX 1080 Ti Duke 11G OC delivers 11GB of GDDR5X memory across a 352-bit bus. Its 3584 stream processors run at a 1531 MHz core clock and a 1645 MHz boost clock. The card targets enthusiasts building high-refresh 1440p or entry-level 4K rigs. DirectX 12 and OpenGL 4.5 support cover modern API requirements.

Triple-Fan Cooler with Multi-Monitor Outputs

A custom triple-fan cooler replaces the reference blower for lower acoustic output under load. The rear bracket provides one dual-link DVI-D port, two HDMI ports and two DisplayPort connectors. This layout drives up to four displays simultaneously without adapters. The physical slot bracket occupies two expansion slots in the chassis.

PCI Express 3.0 x16 Bandwidth Ceiling

The GPU communicates over a PCI Express 3.0 x16 link, capping theoretical throughput at the 3.0 specification limit. This interface is sufficient for the 1080 Ti's 352-bit memory subsystem at stock clocks. Systems limited to PCIe 2.0 x16 will see reduced bandwidth in texture-heavy workloads. The card draws auxiliary power through two 8-pin connectors.

Questions about this item

Will the 11 GB GDDR5X memory or 3584 stream processors need replacement later?

The 11 GB GDDR5X memory and 3584 stream processors are soldered to the board and not user-replaceable; only the dual-fan cooler may need dust cleaning or fan swap over time.

What limit appears first during sustained load on the 352-bit bus and 1645 MHz boost clock?

The 352-bit GDDR5X bus and 1645 MHz boost clock will hit the card's power and thermal ceiling first, capping sustained performance before memory bandwidth saturates.

How loud and hot does the dual-fan cooler get when the 3584 stream processors run all day?

The dual-fan cooler exhausts heat into the case; fan speed rises to maintain the 1645 MHz boost, producing noticeable airflow noise under continuous load.
