Introduction to Overclocking and the Basics

Supermicro's dedication to the enthusiast high-end desktop world has recently been solidified with the launch of their C9X299-PG300, which is not only designed to provide you with the latest technologies, but also support 300W power consumption off the bat.


The motherboard fully supports a 300W TDP, which is crazy high, and to do that it utilizes one of the strongest 8-phase VRMs found on a motherboard.

It utilizes the latest in Infineon PWM control technology and power stages, and today we will teach you how to overclock Skylake-X CPUs on the platform, specifically with this motherboard. Many might not be that familiar with Supermicro's UEFI BIOS, but we are happy to report all the settings are present to allow you to overclock your CPU and memory with ease, and we have been commissioned by Supermicro to bring you this article on how to overclock their new motherboard. The review of this motherboard is up, so if you have more questions not covered here, please look at that.

The Flow Chart


The flow chart above details how to begin to think about overclocking a Skylake-X CPU. The first thing you need to realize is that there are two types of Skylake-X chips; low core count (LCC) and high core count (HCC) dies. As a rule of thumb, the 7900X and CPUs below it use the LCC die, while the 7920X and above use the HCC die. The difference in regards to cooling capability without delidding is quite large as the HCC dies make much more contact with the internal heat spreader and can be cooled more easily. However, they also draw a lot more power, especially the 7980XE and 7960X.
