STRIX X670E-F - any problems I should know of?

Level 7
Hi, I want to buy this board, but I need to be sure everything works as it should.

I know about this problem with X670, this is not even such a problem for me:

I now have Gigabyte X670E Aorus Master and it is just a PITA. BIOS is very sluggish. This is dependent on RAM temperature, or it could be chipset or VRM temperature. I only know it gets sluggish if I stress test RAM.
As soon as Windows login screen appears, everything is fine without any stutters.

Now it took exactly 15min to get from BSOD in Win (too low tRFC, I'm trying to find lowest subtimings, but so far no luck compared to XMP) to setting tRFC from 820 to 850, then another BSOD before Win, then setting to 870 (XMP is 884). And now I am writing this from anew because only thread title got saved.
Even at DEL screen I have to wait for at least a minute to get moving forward. Then same at Aorus screen with circle Windows loading icon.
And in BIOS keyboard keys react very slow, same with mouse movement.
RAM is now at 43°C. I already know this is too much and the BIOS will be very sluggish if I go into it now. Best would be to wait 1-2h. What I described above was after 20min in idle. But really fast it is only in the morning as it has time to cool down, I think 36-40°C.
(EDIT: after 30min 41°C, that should be enough cool to not wait forever in BIOS)

My RAM is this one, Trident Z5 RGB DDR5-6000 CL36-36-36-96 1.35V 32GB (2x16GB) Intel XMP:

One stick was faulty, but I am now on the good stick, Karhu 2h+ and Coverage 8000%.

Tomorrow I will buy this RAM, Trident Z5 Neo RGB DDR5-6000 CL30-38-38-96 1.35V 32GB (2x16GB) AMD EXPO:

I already know XMP/EXPO doesn't make much difference, they have same subtimings. But I will still buy this one because of having Hynix ICs which are supposed to be cooler than Samsung.

So now to the question about this Strix F board.
1. Does 6000 30-38-38 work without problems? On Gigabyte 6000 works only with latest BIOS, before that only 4800, with 5200 it booted, but hanged on reboot.
G.Skill QVL states only Strix E.
Then on ASUS Memory Support page there are only four 6000 kits, no changes from release date almost 3 weeks ago. But there is 5600 28-34-34.
So that should mean my 6000 30-38-38 kit will work in best case on EXPO 6000 CL30 and in worst case on 5600 28-34-34.
2. Do you know of any problems, like I have with Gigabyte board (I'm not excluding only mine is faulty)?

Otherwise it seems like a good board. I like it even better than the more expensive Strix E as I need 4x NVMe. With Strix E, GPU PCIe slot gets halved to x8 if you populate the bottom left M.2 slot.

Just had to return one of these boards would not post, kept getting DRAM error, Flashed the BIOS, reset the CMOS, tried two different brands of RAM (went through ASUS help desk)

Not impressed for a high end board have failed out of the box, been using ASUS boards since the 2000's this may well be my last ASUS board build quality is not the same. I am still running the Legendary ASUS Rampage Extreme X48.

Do not buy, especially with ddr5 6000 - there are so many issues and zero support or drivers to help.

Your computer is going to crash, take 10 seconds to open files, and randomly break and you won't be able to fix it.

I was stupid enough to try it with Ryzen9 and also get watchdog bluescreens that are currently unfixable.
