Intel Core i5 7600K quad core CPU, 4.2 to 4.5 GHz, 8M, unlocked multiplier, SR32V, Kaby Lake 91W,

Here is an Intel quad core processor known as the Core i5 7600K.  It will work with many desktops from 6 to 8 years ago which use an Intel Socket 1151 but which can't take an 8th generation or newer LGA1151 CPU.  It runs at 3800 MHz with a maximum Turbo Boost speed of 4200 MHz.  Intel left the multiplier unlocked, for flexibility in overclocking.

It has the "Kaby Lake" core with 14 nanometer traces, an onboard memory controller and 6MB of L3 cache.  Intel's s-spec code is SR32V.  It draws 91W of power.   


You will receive only the exact processor that created the screenshot in the third pictured here.  A CPU cooler is required but not included with this item. If you need a small tube of thermal paste, just ask me to include it in your package.


I guarantee that it will arrive as pictured and working.  I will wrap it in antistatic bubblewrap before shipping it in a padded mailer.


Please feel free to contact me with questions about shipping, compatibility, or anything else related to this CPU before your purchase if you are not sure.   I am happy to answer compatibility questions and would rather tell you no, it won't work for you, than have you find out later.
