The Intel B560 platform will have support for overclocking DDR4 memory

Memory performance is of great importance, and the ability to access the full performance of selected memory modules is one of the key aspects when it comes to getting the most out of the system, especially in a gaming environment.

With the B560 platform, it looks like Intel will finally correct the biggest weaknesses of its previous mid-range chips - the lack of support for memory overclocking. Intel’s B460, B360, and older B series chips only supported memory clock speeds that were officially supported by the processor, limiting DDR4 speeds to 2933MHz, 2666MHz or lower, depending on the processor. This has also limited gaming performance in many systems.
 
As the number of Intel processor cores increased, the speed limits of the company's B-series chips became an increasing performance problem, and the B560 is here to correct that and change the situation. On the other hand, it looks like the budget-oriented Intel H510 chipset will still have limited memory speed limits.
