As you can see, memory tuning is not worth it. At least not on 192 bits.
It's no accident that AMD has locked memory overclocking.
2000-2100Mhz with fast timing is the best choice on 6700XT.

Ok, and I will counter your point. 6750XT
I use 2860 set, about 2820 get on clock speed. voltage is 1160 set, but it doesn't matter AS much.
Sorry, I cannot cover THIS big of a gap between min and max clock, but what I have should be enough
Anyway, let's begin. All was done on Superposition 1080p Extreme and with 265W PL
1. 500 / 2860 / 1160 /
2248 (my minimum) / Default
Results were 7669 and 7676
2. 500 / 2860 / 1160 /
2312 / Default
Results were 7781 and 7782
3. 500/2860/1160/
2248/FT1
Results varied from 7712 to 7762. Why consistency was not as expected, unknown. Maybe background load for some reason?
4. 500/2860/1160/
2312/FT1
Results were 7790 and 7802
I can also say you that with 500 / 2910 / 1160 / 2312 / FT2 (when I stabilize memory for no errors on runtime) results were around 7870-7890 on average. I managed to get 7905 only once and it is my record.
Also, don't forget, it is 1080p, meaning bandwidth is much less of an issue, and it still reacts on change from 2248 to 2312 with quite significant gain. On the other hand, it doesn't react on change from Default timings to FT1 nearly as much. Probably because superposition only checks core frequency and mosrly raw bandwidth because it is precompiled?
I also have data on Heaven 1080p Ultra quality with Extreme tesellation
1) 2262 (i used to compare with more stable value for FT2)/ Default
Score 4311 4315, FPS 171.2 171.3
2) 2262 / FT1
Score 4344 4345, FPS 172.4 172.5
3) 2312 / FT1
Score 4358 4359, FPS 173.0 173.0
4) 2262/FT2
Score 4365 4376, FPS 173.3, 173.7
Granted, now i also know that running 2312/FT2 is possible... Just DO NOT REBOOT if it is stable when you set it. Because VRAM trains during usage? Idk, but it becomes significantly more stable after PC had been on and used for some time. So much that after reboot even 2248/FT2 couldn't be used without stretching artifacts, but after few hours 2312/FT2 is possible to do.
