The third technology Ryzen processors will be capable to match their Intel counterparts on the subject of reminiscence overclocking. In the Zen 2 BIOS, the reminiscence frequency choices go all the best way as much as “DDR4-5000”, which is a big improve over the primary Ryzens. The DRAM clock continues to be linked to the Infinity Fabric (IF) clock area, which suggests at DDR4-5000, Infinity Fabric would tick at 5000 MHz DDR, too. Since that charge is out of attain for IF, AMD has determined so as to add a brand new half divider mode for his or her on-chip bus. When enabled, it’ll run Infinity Fabric at half the DRAM precise clock (eg: 1250 MHz for DDR4-5000).
This might flip into an extra promoting level for AMD X570 chipset motherboards, as they will have a reminiscence frequency headroom benefit over boards based mostly on older chipsets as their BIOS will embrace not simply the elevated reminiscence clock restrict, but additionally the divider mode. Of course this does not imply you could simply magically overclock any reminiscence equipment to those 5 GHz speeds – it is possible that solely the perfect of the perfect modules will be capable to get shut to those speeds.
1usmus additionally found that the platform provides a SoC OC mode and VDDG voltage management. We’ve heard from a number of sources that AMD invested closely in enhancing reminiscence compatibility, particularly within the wake of Samsung discontinuing its B-die DRAM chips.
