Patriot Viper Venom 32 GB (2 x 16 GB) DDR5-7000 CL32 Memory currently set at XMP 6800 @/1.4V because it was unstable at the factory XMP-7000 @/1.45V.
Can anyone please tell me if that result and latency is ok? And if not, what should I do to improve it? I am familiar with CPU and GPU OC, UC, UV and so on, but I have no idea about RAM timings and finetuning.

Try running at 6400MT/s with UCLK=MCLK and FCLK at 2133.34 MHz and try the timings 32-38-38-96 for much better latency and bandwidth performance
Your latency should be ideally close to 60ns, these settings give me 65-66ns on my personal rig.
Anything above 6400 or 6600 runs on UCLK : MCLK :: 1:2 ratio, that adds extra latency and is only worth is above 7600 or 7800 speed and is very bad interns of stability.
Vsoc can be upto 1.25V for a stable long term use, use ZenTimings app for more details about your setup for better before and after logs.
2:1 is generally not worth it below 7600. Try 1:1 mode at lower frequency (6000-6400) and tighten up your subtimings (use Buildzoid’s Low Effort Hynix Timings as a base)
Aida is a crappy benchmark that represents no real world scenario. Use something else, like a heavy code compile test. Those are great for benching CPU and memory.
