Second-Generation Core i7 for LGA 1155 Builds

This quad-core processor fits LGA 1155 motherboards and runs at a base frequency of 3.4GHz with Turbo Boost up to 3.8GHz. It is aimed at enthusiasts who want an unlocked multiplier for overclocking on a mature platform. The 32nm Sandy Bridge architecture includes Hyper-Threading for eight logical threads.

95W Thermal Design Without a Cooler

The 95W TDP means a capable aftermarket cooler is required because none is supplied in the box. Integrated Intel HD Graphics 3000 runs at 850MHz and provides display output on boards with video ports. The dual-channel memory controller supports DDR3-1066 and DDR3-1333 for straightforward RAM selection.

Unlocked Multiplier for Overclocking

The K-series designation signals an unlocked ratio multiplier, the single specification that lets builders push frequencies beyond the stock 3.8GHz Turbo ceiling. Combined with 8MB of L3 cache and AVX instruction support, this trait decides whether the chip matches a performance-focused build or a locked alternative would suffice.

Fragen zu diesem Artikel

What memory speed does the integrated DDR3 controller support?

The integrated memory controller runs dual-channel DDR3 at 1066 or 1333 MT/s.

Which socket and cooler clearance does the LGA 1155 package require?

It fits LGA 1155 motherboards; the 95 W TDP means a standard boxed cooler or equivalent aftermarket cooler is sufficient.

How is the processor seated, and what step is often missed?

Align the notches, lower the CPU gently, close the retention lever, then apply thermal paste before mounting the cooler — skipping the paste is the common error.
