The newest Intel Haswell-E processors are already pretty fast out of the box, but if you want to you can squeeze a lot more performance out of them. This workshop shows you how to achieve the optimum overclock.

The Intel Haswell-E processor family was introduced at the end of August 2014, click here for our extensive review. Overclocking the Haswell-E chips is comparable to the methods used on the "normal" socket 1150 Haswell CPU, but because of the DDR4 memory as well as other improvements there are quite a few differences. This article shows you in easy steps how to get the best possible performance out of the Haswell-E chips.

It is an added bonus that all three Haswell-E CPUs on the market are unlocked, not just the top model Core i7 5960X but also the cheaper 6-core Core i7 5930K and 5820K. This enables the overclocker to work with any of these processors without having to worry about limitations.
