 "Intel Core i7-7700K, 4x 4.20GHz, boxed without cooler" 4.20GHz i7-7700K
"The Core i7-7700K 4.2 GHz Quad-Core LGA 1151 Processor from Intel has a base clock speed of 4.2 GHz and comes with features such as Intel Turbo Boost 2.0 and Intel Hyper-Threading technology. With Intel Turbo Boost 2.0 technology, the maximum turbo frequency this processor can achieve is 4.5 GHz. Additionally, this processor features 4 cores with 8 threads in an LGA 1151 socket and has 8MB of cache memory. Having 4 cores allows the processor to run multiple programs simultaneously without slowing down the system, while the 8 threads allow a basic ordered sequence of instructions to be passed through or processed by a single CPU core. This processor also supports up to 64GB of DDR4-2400/2133 and DDR3L 1600/1333 RAM at 1.35V, has AES New Instructions, 14nm lithography, and utilizes 7th Generation (Kaby Lake) technology.Graphically, the Core i7-7700K 4.2 GHz Quad-Core LGA 1151 Processor uses integrated Intel HD Graphics 630. This processor is also unlocked, meaning that it can be overclocked past its maximum turbo frequency. However, overclocking past the maximum turbo frequency is not recommended. Not only will it cause the processor to run much hotter, it will also void warranty.
