Query – AM4 theoretical query relating to DDR4 reminiscence speeds


AMD says they’ll proceed to help the AM4 platform. I’ve been occupied with the reminiscence speeds. May AMD create a XMP like OCing setting the place the minimal reminiscence velocity could be 3200mhz. The usual DDR4 default clock velocity is 2133mhz. AM4 maxes out the reminiscence divider @ 3800mhz reminiscence speeds. May they merely push the start medium reminiscence velocity to 3200mhz and thus push the 1:1 divider ratio up 1037mhz (2133-3200mhz) as a place to begin. In idea that may forestall the reminiscence divider from introducing large reminiscence latency above 3800mhz to a brand new max reminiscence 1:1 ratio of 4807mhz DDR4 reminiscence velocity.

Primarily simply sliding up the place to begin of the reminiscence from 2133mhz to 3200mhz. If that is potential that may considerably enhance AM4 efficiency from the B350 all the way in which as much as the X570 boards since AMD mounted the reminiscence points affecting the B350/X370 boards with the newest AGESA launch.

DDR4 reminiscence kits have a number of efficiency that’s being left on the desk. I’ve some Hynix CRJ sticks that claims on the packaging the sticks are able to 4500mhz+.

Ideas on this being potential?
