Dual-GPU Hemlock architecture

The Sapphire Tech Radeon HD 5970 100280SR combines two AMD Radeon GPUs on a single PCI Express 2.1 x16 board. It delivers 3200 stream processors and 2GB of GDDR5 memory across a 512-bit interface. The card targets enthusiasts who need maximum parallel throughput for DirectX 11 titles and multi-display Eyefinity setups.

Reference dual-slot cooler with two external power

A shrouded fan assembly exhausts heat toward the rear I/O bracket. The design draws up to 75W from a 6-pin connector and 150W from an 8-pin connector, so a 650W supply is the minimum for single-card operation. CrossFireX dual mode raises the recommendation to 850W with two 6-pin and two 8-pin connectors.

Compact dual-slot bracket with Mini DisplayPort

The metal bracket occupies two expansion slots and carries one Mini DisplayPort plus two DVI outputs, supporting resolutions up to 2560 x 1600. Eyefinity can drive three monitors from this single card. CrossFireX bridge fingers sit on the top edge for linking a second 5970 when the power budget allows.

Questions about this item

How do I install the Sapphire 100280SR and which power cables are required?

Seat the card in a PCI Express 2.1 x16 slot and connect both the 6-pin and 8-pin PCIe power connectors from a 650 W or larger supply; the 8-pin must deliver 150 W and the 6-pin 75 W, so do not use adapters or splitters.

What maintenance will the dual-GPU cooler need over time?

The dual-fan shroud pulls air across both 5970 GPUs; every few months remove the card and blow compressed air through the heatsink fins to stop dust build-up raising core temperatures.

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

With a 3200 stream-processor design drawing up to 150 W through the 8-pin and 75 W through the 6-pin, the power connectors and VRM cooling reach their ceiling before the GDDR5 memory does.
