Socket LGA 2066 quad-core

The Intel Core i7-7740X is a desktop processor built for the LGA 2066 platform. It delivers four cores and eight threads with a 4.3 GHz base clock and a 4.5 GHz max turbo frequency. The 14nm Kaby Lake X architecture supports DDR4-2666 memory in dual-channel mode. It targets enthusiasts who need high single-thread speed on an X299 chipset board.

Check motherboard and cooling

Verify that your motherboard uses the Intel X299 chipset and an LGA 2066 socket before ordering. The CPU has a 112W thermal design power and ships without a cooler or thermal paste, so a suitable aftermarket solution is required. Ensure the BIOS version supports Kaby Lake X processors. Only sixteen PCI Express 3.0 lanes are available from the chip itself.

Upgrade from quad-core mainstream

This processor replaces a mainstream four-core CPU when you need the X299 platform's quad-channel memory capability and additional connectivity. The jump is worthwhile if your workload benefits from higher clock speeds and the 8MB L3 cache on a 14nm design. It fits builds that prioritise frequency over core count within the 112W envelope.

Ερωτήσεις για αυτό το προϊόν

Does the Core i7-7740X come with a cooler or thermal paste in the box?

The processor is sold without a cooler or thermal paste; both must be purchased separately for installation.

Which memory speed should I pair with the Core i7-7740X?

The CPU officially supports DDR4-2666 in dual-channel mode; faster kits will run at this speed unless the motherboard and BIOS allow higher XMP profiles.

What does the 4.5 GHz max turbo frequency mean for everyday workloads?

The 4.5 GHz peak applies to single-thread bursts within the 112 W thermal envelope; sustained all-core speeds will settle lower depending on cooling and motherboard power limits.
