Hybrid GTX 1080 Ti for enthusiasts

The EVGA GeForce GTX 1080 Ti SC2 Hybrid targets enthusiasts who want liquid cooling without custom loops. It pairs an NVIDIA Pascal GPU with 11GB GDDR5X memory on a 352-Bit interface. The card delivers a 1556 MHz base clock and 1670 MHz boost clock across 3584 CUDA cores for high frame rates at 4K resolution.

PCIe 3.0 slot plus 120mm radiator mount

Installation requires a PCI Express 3.0 x16 slot and case space for the 120mm all-in-one radiator and fan. The self-contained loop arrives pre-filled so no coolant handling is needed. Builders sometimes forget to connect the VRM fan header or to route the DisplayPort 1.4 and HDMI 2.0b cables before securing the radiator.

11GB GDDR5X decides 4K viability

The 11GB GDDR5X frame buffer running at 11016 MHz effective clock is the single specification that determines whether this card suits a 4K workflow. It supports DirectX 12, OpenGL 4.5 and up to 7680 x 4320 output across four monitors via three DisplayPort 1.4 and one HDMI 2.0b connector.

Questions about this item

How can I verify the EVGA GeForce GTX 1080 Ti SC2 Hybrid is running correctly after installation?

Check that the GPU core clock reads 1556 MHz and boost clock reaches 1670 MHz under load; use EVGA Precision XOC to monitor the nine iCX thermal sensors across the GPU, VRM and memory, confirming the hybrid water block and VRM fan are actively cooling each zone.

What comes in the box with the 11G-P4-6598-KR and what must I purchase separately?

The card ships with the self-contained 120mm all-in-one water cooler, a dedicated VRM heatsink with fan, a memory cooling plate integrated into the block, and mounting hardware; you must supply a case with a 120mm radiator mount, a PCIe 3.0 x16 slot, and an adequate power supply with the required 8-pin connectors.

Which version of the EVGA GTX 1080 Ti SC2 Hybrid should I choose for my build?

The 11G-P4-6598-KR is the single SKU offered — it provides 11GB GDDR5X memory on a 352-bit bus, 3584 CUDA cores, and a hybrid cooler with iCX Technology; there are no alternative capacity or cooling variants listed for this model.
