Overclocking on Skyalake-X is not all that hard at all if you are familiar with Intel overclocking. We are not going to go into much detail here as we plan to do a follow-up article, but we were able to get all 10 cores of the i9-7900X at 4.6 GHz.
Obviously when you move this processor away from its stock settings it will get a little hot. With all cores at 4.6 GHz and 100% load our Kraken X52 was able to handle it, but things were a little hot, up to 88C!
To give you an idea of how much more performance that 300 MHz bump gives you we ran a few of our normal tests again.
