This motherboard is not good to overclock memory.

Why not?

I also open same topic in Reddit. There is another couple person has same trouble. Even here some people same.
Such a shame for Asus. They should fix peoples problem for Z790 boards and DDR5 rams.
What is the reason to buy 7600mhz ram and use 6200-6600-7000mhz.
Still seeking some bios settings or new bios update.

@MMANHB and @claudiomp
We try to run our ram's stock frequency and stock timing, Even mobo officially supporting 7800mhz DDR5 Rams. This is not overclocking attempt.
Can you explain why you think ROG Strix Z790-E is not good for overclocking?

I've had some success getting higher speeds working on my 7200 34-45-45 kit (booted at 7800) with some very high voltages. I think I tried as high as 1.6V in increments, and it definitely helps.

That said, you probably want to get your RAM cooler before you try that. I have plenty of airflow over the DIMMs.

Also, make sure you have the newest BIOS (from Nov. 8th I believe.) It helped get my 7200 kit working at XMP.

@littledonny I will consider about high voltages. Might be help to improve stability. Is your mobo Strix Z790-E Gaming?

Yes. But make sure you have adequate cooling all over the top of the board for this.

I tested quite high voltages. Around 1,50-1,60v. 7600-7800 and 8000mhz It didn't improve my stability. All frequences doesn't stable. I only stable in 7400mhz.
in 1,60v ram's getting 70C after 15-20 min. I have active fans flowing through to rams.

Using BIOS 0703 from November 1st? If so, I'm out of suggestions
