Overclocking

Your DDR5 shows 4800 MT/s instead of the 6000 on the box because the fast profile ships off, not because anything is broken. Here is the one BIOS toggle that fixes it — and why the payoff is big on a 7700X and tiny on a 7800X3D.

DDR5-6000 CL30 and DDR5-6400 CL32 have identical 10.0 ns true latency, so gaming lands within a couple percent. The real tiebreaker on AM5 is the 1:1 memory ratio — where a faster 6400 kit can end up slower than 6000.
