Can Ryzen 9 3900X run 4400mhz memory?

Question

Processors

Who will tell you, I haven’t come across this, here Ryzen 9 3900X supports RAM up to 3200mhz, and I chose the mother MSI MPG X570 GAMING PRO CARBON WIFI which can work with memory up to 4400mhz, and if I put 16GB modules with 4400mhz, the percent will only work on 3200mhz? Why then acceleration is needed I do not understand ...?

Answer 1

Depends on memory. Now Infinity Fabric has two modes. 1d1 and 1d2. 1k1 works up to about 3733-3800 MHz. Then the mode switches to 1k2 and the IF speed is halved, so the memory will work at 4400 MHz, but there will be no profit from this. For the Ryzen 3000 series, the optimal memory mode is 3800 MHz in IF 1: 1 mode
. In principle, the processor itself can not be driven. AMD has made amazing automation in the 3000 series that works better than human overclocking.
