Overclockers UK Pre-Binned: Performance Guaranteed

What is a Pre Binned CPU?

All CPU's can hit the boost clock as advertised but not all 'K' chips can surpass it due to minute imperfections in the silicon. Not a single CPU is created equally and all perform differently with less than 5% being able to perform to our highest guaranteed frequency. Pre Binned CPU's remove what is known as the silicon lottery and allow you to buy one of the most capable CPU's in the world.

High performance, overclockable CPUs are highly prized and would cost an individual tens of thousands of pounds to manually source and test hundreds of processors finding less than a 'handful' of what are required to make the grade. Why spend more? Save the hard work for us!

8pack binning

How are CPUs 'Binned'?

Each CPU is individually tested by the world renowned Overclocker 8Pack on specially designed testing rigs which utilise the very latest ASUS STRIX/ROG Motherboards and Corsair 3200Mhz RAM. Each rig has been configured to utilise pre-determined voltages and settings which allow 8Pack to determine what the silicon is capable of. The CPU's are graded into categories with the very highest being De-Lidded and used in our 8Pack and Infin8 systems with any excess being sold as pre binned. Any CPUs that don't meet the standards required are not simply put back into stock but held for projects or used in any of our machines destined for events.

What is De-Lidding and are there thermal benefits?

8pack delidded CPU

All of the CPU's that make the grade are de-Lidded. This is a process of whereby the CPU's IHS (Integrated Heat Spreader) is momentarily removed and the TIM (Thermal Interface Material) is replaced with one that has far superior heat transfer properties such as Liquid Metal. The technique of De-Lidding can reduce load temperatures on average by 10-20°c offering the ultimate in overclocking thermal performance.
