This profile i used is made from asus so must work without problems!
Which profile exactly are you talking about? The DRAM tuning menu offers a couple of profiles for specific memory chips. However the profile might be for slightly different specs as whitnessed by the timings which do not match your profile. So if you load a profile which is not precisely for your chips and module it might or might not work.
In general it's not the mainboard having to provide memory modules. It's the memory module which provides the profile to the mainboard (EXPO/XMP). Moreover you are using a module which was optimized for Intel (XMP). ASUS is offering to use XMP profiles and adapting them to their best knowledge to AMD specifications - this is what they call DOCP.
Using AMD optimized modules (with EXPO profile) is more advisable on AMD platforms. I guess also for DOCP you can select something like on EXPO profile I or II. Profile 1 is optimized settings (the mainboard taking the SPD-EEPROM data from the module and adjusting some of those). While Profile 2 is keeping exactly the timings specifyed by the memory module (usually the most stable option).
If you go to the DRAM menu and load a chip-specific setting you are going to overwrite those settings by parameters completely ignoring your memory module SPD-EEPROM data and trying to optimize for the memory chips on the module. However this is very risky also as people do not understand that not only the chips but also the layout and even trace routing on the module has an impact on timings. So essentially only the module manufacturer knows what is tested and validated.
Also you might have noticed that there are multiple profiles for the same DDR5 speed. And this applies to your module too - you cannot just load any Samsung or Hynix DDR5-6400 profile just because you got Samsung/Hynix chips and your module is supposed to be DDR5-6400 approved. That's not how it works.
So again I do recommend first to test "Auto" settings and validate if your system is all-time stable using JEDEC DDR5-4800 timings. Btw. this is also the highest speed AMD actually offering full support for. The Ryzen 7000 specs do not include any higher specification. Everything above DDR5-4800 is overclocking territory.
If your system is proven to be stable at DDR5-4800 speeds then enable EXPO/XMP/DOCP-I profile and try again - do not customize any timings or load further profiles. If it is not stable then try increasing MC voltage and for your modules assure DRAM VDD and VDDQ is set to 1.4V as of the module specification.
If this is all stable, then you might go into the DRAM timings menu and start optimizing some of the timings. But do not expect any significant performance boosts anyway. In most applications you might only see a single-digit uplift in performance on memory-intense applications comparing DDR5-5800 default and DDR5-6400 with optimized and hand-tuned (perhaps unstable) settings. So it's usually not worth the hassle.
