+ | == Overclocking == | ||
+ | The 7820x CPU overclocks to 4.6ghz on all cores relatively easily and 4.8ghz on all cores is also pretty common overclock. 4.9 and 5.0ghz can be tricky but are not uncommon and only obtainable if sufficient cooling is achieved. Generally, 4.5Ghz is a common overclock on quality air coolers and beyond that water-cooling is needed for sustained higher overclocks. | ||
+ | |||
+ | Stock out of the box using Intel® Turbo Boost Max Technology 3.0 Frequency the CPU will overclock 2 cores to 4.5ghz. | ||
+ | |||
+ | The quad memory controller of the Skylake-X CPUs have advanced overclocking ability such as in the case of Corsair Dominator Platinum 3600mhz memory will easily overclock to 3,800mhz - 4,000mhz. At 3,800mhz total memory bandwidth is around 101GB/s Read and 107GB/s Write with Copy at 97.2GB/s. |
