Targeted VR Desktop CPU

The Intel Core i7-7740X is a quad-core desktop processor with eight threads for VR-focused builds. It runs at 4.3 GHz base and reaches 4.5 GHz max turbo on the LGA 2066 platform. The 14 nm Kaby Lake-X architecture supports DDR4-2666 memory in two channels. An unlocked multiplier allows manual frequency tuning.

Processor-Only Package

The unit ships without a cooler or thermal paste, so a separate LGA 2066-compatible solution is required. No integrated graphics are present, meaning a discrete GPU must be installed for display output. The 112 W thermal design power dictates the cooling capacity needed for sustained loads.

X299 Platform Connectivity

Compatible X299 motherboards provide 16 PCI Express lanes from this processor for graphics and storage devices. Dual-channel DDR4 support populates up to four DIMM slots depending on board layout. The LGA 2066 socket and 64-bit instruction set define the platform constraints for this 8 MB L3 cache chip.

Questions about this item

Will the i7-7740X need a new cooler when I install it?

The processor ships without a cooling device, so a compatible LGA 2066 cooler and thermal paste must be supplied at build time.

What limits sustained performance on the i7-7740X?

The 112 W thermal design power and 4.5 GHz max turbo frequency define the ceiling before throttling or power limits engage.

How much heat and noise should I expect from the i7-7740X running all day?

With a 112 W TDP and no stock cooler, actual temperatures and fan noise depend entirely on the aftermarket cooler chosen for the LGA 2066 socket.
