Ivy Bridge quad-core for LGA 1155

This desktop processor fits LGA 1155 motherboards and delivers four cores at 3.4 GHz with a 3.8 GHz turbo frequency. The 22 nm design runs at a 77 W thermal rating and includes Intel HD Graphics 4000 for basic display output. It suits builders upgrading or maintaining a 3rd-generation Core i5 platform.

Dual-channel DDR3 controller limits memory speed

The integrated memory controller supports DDR3 at 1333 and 1600 MT/s in dual-channel mode. Faster modules will down-clock to the highest supported rate, so purchasing memory beyond 1600 provides no benefit. System bandwidth is therefore capped by the controller specification rather than the DIMMs themselves.

Unlocked multiplier enables overclocking

The K-series suffix means the ratio multiplier is unlocked, allowing frequency increases when paired with a Z77 or similar chipset. On non-Z chipsets the multiplier remains locked, so the 3.8 GHz turbo ceiling becomes the practical maximum. Choose this part only if the motherboard chipset permits multiplier adjustment.

Questions about this item

Should I pick the 3.4 GHz base or the 3.8 GHz turbo version?

This single processor runs at 3.4 GHz normally and automatically boosts to 3.8 GHz when thermal headroom allows, so there is no separate version to choose.

What does the 3.8 GHz turbo actually deliver in a built PC?

The chip can hit 3.8 GHz on active cores while staying within its 77 W envelope, giving a measurable lift in bursty workloads such as game loading or compile spikes.

Which memory speeds does the LGA 1155 memory controller officially support?

The integrated dual-channel controller is validated for DDR3-1333 and DDR3-1600; faster modules will run at the highest supported speed.
