Product information: Core i7-7700K 4.2GHz (Kaby Lake) Socket LGA1151 Processor - Retail

Intel Kaby Lake is Skylake perfected with improved performance clock for clock and vastly superior overclocking ability on K series processors. Intel's 7th generation processors use the S1151 socket and are compatible with Intel Z100 and Z200 Series chipset motherboards such as Z170 and Z270.

In our own testing here at OcUK HQ in our technical labs our very own 8 Pack has being overclocking these processors as high as 5.2GHz on good air cooling and AIO setups, moving to a full blown water cooling loop helps further lower temperatures and improve stability when pushing beyond 5GHz. On more serious hardcore cooling by professionals and overclocking champions such as Overclockers UK very own 8 Pack as high as 7GHz has being seen. Of course overclocking is not guaranteed but we do have some 8 Pack and 8 Pack approved bundles and systems where you can order with CPU overclocks guaranteed as high a 5.2GHz for a premium.

This is a retail boxed processor and comes with Intel 3yr warranty and is un-opened and brand new, so your overclocking mileage is down to yourself and luck of the draw but Kabylake promises to push the envelope the furthest yet when it comes to frequencies making them ideal for games and applications that require outright pure MHz performance and they still have incredible multi core performance as well.

Fast but hot

Amazing processor - it won't be the bottleneck in your system!

I have found that for overclocks 4.9ghz and above, the chip runs hot, even with voltages finely tuned.

The way the cpus own heat spreader it connected to the chip is very poor and so whatever cooling solution you have, it doesn't make a huge difference. Temps can spike and most mobos like to run fans at 100% once it reaches 75 degrees so I would recommend a 360mm AIO as a minimum.

blazing fast chip

I purchased this for my new build,
blazing fast chip with 4.5Ghz turbo.
overclocking is great i would suggest you get more efficient cooling than the previous gens (comeing from i7 3770k ivy bridge) this new chip runs much hotter.

    "Since the release of the 2nd Generation of Intel Core Processors they have been dominating the market with a combination of affordability and performance. Whether you have gone down the i5 route with models such as the 2500K or 6600K, or have been sticking to the Core i7 hyperthreading models such as the i7-2600K or i7-4790K, it is fair to say that you'll have been pleased with your purchase."
