Ivy Bridge quad-core for LGA 1155 builds
The Intel Core i7-3770 is a 22 nm quad-core desktop processor that plugs into an LGA 1155 socket. It targets owners of compatible 6-series or 7-series motherboards who need a drop-in upgrade without changing the platform.
3.4 GHz base with 3.9 GHz turbo and 8 MB L3 cache
Four cores run at 3.4 GHz and can lift to 3.9 GHz on lighter loads. The shared 8 MB L3 cache and 5 GT/s DMI link keep data flowing to the execution units during multitasking or legacy gaming workloads.
Standard LGA 1155 mounting; match cooler to 77 W TDP
The chip uses the stock LGA 1155 retention bracket so any compatible cooler screws straight down. Problems usually come from forgetting to update the motherboard BIOS for Ivy Bridge support or pairing a cooler rated below the 77 W thermal design power.

Questions sur cet article
What does the 3.9 GHz turbo frequency actually deliver in everyday workloads?
The 3.9 GHz turbo activates when thermal headroom allows, giving short bursts of extra speed for single-threaded tasks such as application launch or light rendering before the 77 W limit brings clocks back toward the 3.4 GHz base.
How does the LGA 1155 socket and 5 GT/s DMI link constrain upgrade options?
LGA 1155 locks the processor to 6- and 7-series chipsets, and the 5 GT/s DMI caps total throughput between CPU and chipset, so newer storage or USB controllers cannot exceed that bandwidth.
What cooler clearance and memory slots does the 77 W Ivy Bridge quad-core require?
A standard LGA 1155 cooler rated for at least 77 W is sufficient, and the dual-channel DDR3 controller supports DDR3-1333 and DDR3-1600 modules in the motherboard's DIMM slots.
