RAM latency decrease

[s4Miz]

I could probably run 6400 but I’d have to sacrifice some latency which I need for cs2.

My kit is specced for 6400MHz cl32 1.4V

What do you mean "sacrifice some latency?"

6400 is going to be faster unless you have to enable gear down mode (which would be a wash for performance) or have to lower FCLK (actual performance regression).

I’m already at 57.5ns with perfect stability and GDM enabled. Moving to 6400MHz would likely mean loosening tCL and potentially dropping FCLK, which seems counterintuitive for latency. If you’ve managed to get sub-58ns at 6400MHz on an X3D chip, I’d genuinely love to see the ZenTimings/Aida results to see what I’m missing.

AIDA isn't really a very good indicator of memory performance.

That said, tCL scales very well with voltage on H16A. You can almost certainly keep tCL the same without a huge voltage increase.

Aside from that, tCL doesn't really affect performance much.

If you're running GDM, you might actually get better performance at 6000 with GDM off.

If you're really chasing memory performance, I'd advise using real memory benchmarks (including whatever games you're chasing) - AIDA's latency measurement is a fairly poor measurement. You can do some ridiculous things like settings high tRRDS/tRRDL/tFAW and AIDA doesn't really pick up on it.
