Even if I want to know what the best latencies are for a 2×32 kit

Low effort Single rank Hynix 16Gb A/M-die timings for Ryzen 7000 at 6000Mbps
These timings should work on pretty much any hynix based DDR5 kit that is currently available(16Gb M-die and A-die at the time of writing). At DDR5-6000.
Voltages
VDDIO / MVDD / MVDDQ: 1.35V
VSOC: 1.25V

At least you should lower your tRFC2 and tRFCsb, and raise tREFI, that should decrease latencies. Check for all tretiary timings, like tWRWR or tRDRD, on DDR5 they can give high bandwidth boost.

Looks like you’re just posting your xmp profile. An easy boost you can do is to set your mclk to = your uclk. Asus likes to set it at 1/2 for xmp profiles now.
