Hi folks
I made my system in last week. I spent many hours and effort but i couldn't tweak my ram frequency and timings. Even i'm not very stable in my ram's stock frequency (7600mhz)
My system:
Asus ROG strix Z790E Gaming
Intel 13900KF
Gskill (2x16GB) Trident Z5RGB 7600MHz CL36D

I'm very stable 7400mhz with XMP2 profile. I can boot 7600-7800 even 8000mhz. But it wasn't stable. I put 1,4v Rams and 1,350v for memory controller. All other bios options default.
I need to improve my timing and ram stability but i didn't success. Is anybody advice some settings on bios or anything else.
And i wonder what is the maximum safe temperatures for DDR5 Rams. I noticed that while stress test on my rams is about 63-64 degree. (more than 1 hours TestMem5 absolute test)
Best regards

This motherboard is not good to overclock memory.

It's been close to a month or so since I got the strix motherboard with GSkill 7600 DDR5 rams + 13900K. At the very first days I was able to boot and use the system with XMP 1 for a while before it crashed with bluescreens and random reboots. It wasn't stable at all so I just disabled the XMP and used Auto for all settings.

The rams ran at 4800 and mostly with no problems. While playing COD Warzone 2.0 DMZ I started to get random crashes and random reboots, sometimes in an hour, sometimes after 3-5 hours of playing. The only reason I tried long play sessions was to see if it would crash or not and yes it did most of the time.

Yesterday, I decided to play around a little bit more and saw that there was a BIOS update for strix (Version 0703). I updated my bios and tried XMP 2 @ 7600Mhz. The system booted but froze after 30 minutes or so while just browsing. Before the bios update I wasn't even able to boot with XMP 2. Then I ran memtest and saw I was getting errors @7600Mhz.

Now I disabled XMP and manually set the rams to run @6400 and everything works fine. No random freezes and no random reboots so far, even after long sessions yesterday.

I will play around a bit more with XMP 2 and 7400. I've read that running at maximum speeds is not good and it has a higher probability to fail.

(By the way I don't have a lot of experience with these things even though I've been playing around with pcs since 97).

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.

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.

Yes. I have 0703 Bios. And this bios is really better than old 503 bios. I was stuck 6800-7000mhz. When i try 703bios it makes me stable 7400mhz. Maybe we will have better bios in the future. :unsure: btw thanks for your advice!

You may be at the limit of your CPU's IMC.I have the same setup, and I am stuck at 7400MT's at the moment.

It looks like so much bother to try to get DDR5 8000+ even on super expensive boards. People always asking why I didn't move onto DDR5, this is exactly why.

With DDR4, £325 board, 1 year old £180 4400 ram, 4300CL14 G1.

Too much effort and cost, moreso on the motherboard to get top DDR5 overclocks.
