About Overclockers

Mark Proudfoot had the idea for what was to become Overclockers UK in 1999. Selling stable overclocked CPUs helps to take the risk out of overclocking. “Overclocking” is configuring hardware to operate much faster than manufacturer standards, which voids the warranty. Overclockers UK opened its first premises in Stoke-on-Trent in 2000, moving to Newcastle-under-Lyme in 2009. Caseking acquired the company in 2012. This led to changing the name to OCUK Ltd, moving to a bigger facility, and opening a custom shop.
