X570 TUF PLUS (WIFI) Can't boot with 3600mhz Ram

[Fener]

Hello,

for some time, I can no longer boot with the ram set to 3600mhz. It's a rather strange problem because up to now (I've had this motherboard for 3 years) everything has always worked correctly. I update the bios whenever a new one is released, and the only parameters I set manually was the memory frequency. I have 4 crucial 3600mhz memory banks (8gb*4) and the only way to be able to start the pc is to leave the ram speed in AUTO mode, which is set at 2666mhz. if I swap the banks of ram between the various slots the pc seems to hold up to the speed of 3600mhz for a few weeks. Is there anyone having the same problem as me? Here is my PC configuration:
-Ryzen 3700x
-Crucial 3600mhz 4x8gb
-Asus X570 TUF PLUS WIFI (bios 4602)
-Nvidia 1050ti
-Corsair 750w psu.

Thank you in advance

Hello,

What did you change if anything leading up to the system not working? Can you specify which memory kit part number you're using?

I change sata cable for my hard disk, and when i boot up the bios can't boot with previous settings (3600mhz ram). But i opened the pc again, I swap the ram modules in the 4 slots and the bios saves succefully the frequency option. Yesterday while i was watching a video on facebook, suddenly the system froze for 10 seconds then shut down, without any BSOD. When the pc turned on again, the boot signaled me that it could not start the system with the ram at 3600mhz.
The ram banks are all the same, but bought at different times. The first two in 2019, the remaining last year. Below are the screenshots of cpuz. thank you

Clear BIOS and reset BIOS to default boot options and just use 2 RAM stick brought at the same time in the recommended slots, set the RAM settings manually instead of using AUTO or DOCP/XMP from the memory manufacturer 3600MHz settings eg timings & voltage.

Use MemTest86 USB to test the RAM for both pairs.

hi.

I checked the ram banks with memtest86. I placed the pairs inside the recommended slots (as reported in the motherboard manual, they are the gray ones called B2 and A2. First of all, I reset the bios by bridging the jumpers, after which I set the speed to 3600mhz (the voltage was automatically set to 1.35v.) For both banks, I successfully completed all tests, which were repeated 4 times by memtest. I noted in the summary that memtest was reading a current voltage of 1.2v, but I'm sure that in the bios was set to 1.35 (I checked before and after starting memtest)
After about 4 hours of testing in total, I installed all the ram banks, reset the bios again and set the parameters of interest to me. I am currently writing to you with my 32gb of ram at 3600mhz. I hope no more errors occur. Can I do some more tests?

This is the result:

Use the system, in that case. It may have been changing the order of the modules helped with retraining. Come back if you experience any further instability.

Hi,

If the RAM passed using the MemTest86 USB on the thorough test then it's usually a good sign that the RAM modules are working properly.

Next, you could try using something like AIDA64 or similar program in Windows to stress test certain combination of CPU, FPU, Cache & System Memory.

Hi everyone. Yesterday I ran a prime95 blend test for about an hour without any problems. The cpu temperature was under control (unfortunately I can't verify that ram). I think the system has regained its original stability
