DDR5 RAM Expo - NOT BOOTING

When I set the RAM configuration as EXPO or XMP profile and restart the pc, it works fine. However, the PC does not boot day after. CPU and DRAM leds remains red for forever. The only way that I can open the pc is to cut the electricity and start again. Then, everything looks fine. I have to do same in every morning. I have same issue for BIOS version 3.10. Please help me to figure it out.

Hello!

The maximum RAM speed supported by your CPU, officially, is:
DDR5-5200.
There is no guarantee that RAM kits with higher speeds will run reliably on your system.

If your RAM kit has a slower profile (DDR5-5200, or DDR5-5600) load that profile, and see if the problem gets solved.

If you don't have a lower EXPO profile, then load the profile that you already use, but search in the BIOS menu for "OC Tweaker" and look for the "DRAM Profile" tab.
There, you can load the DDR5-5200 profile, which will change only the DRAM speed, while your timings & voltage remains as set before.
See if this setting solves the issue.

NOTE:
?¢Stress test your system to make sure that it's stable!
?¢Download the free tool, MemTest86, put it on a USB flash drive and run it until it says "Pass"!
(It takes a few hours).
?¢Also, download Cinebench 2024 and let it run until it finishes!

If both of these pass, you'll, probably, no longer run into RAM related issues.

I hope this helps...

The steps in the BIOS of the X670E Taichi are these:

1. OC Tweaker
2. DRAM Profile Configuration <Enter>
3. DRAM Profile Setting <Enter>
4. Select a Profile (for example: EXPO 6000 30-36-36-80 1.4V) <Enter>
5. F10 (Save)
6. Restart

7. OC Tweaker
8. DRAM Frequency <Enter>
9. Select a frequency (for example DDR5-5800) <Enter>
10. F10 (Save) / PC Restarts

NOTE:
The RAM kit will run with the timings & voltage of the EXPO profile, but with the DRAM frequency at 5800MT/s.

I hope this helps.
