DOCP issue RAM 3600 MHz

Hello everyone.

First of all I am new to computing and I know very little, but I recently bought the following setup:

AMD Ryzen 7 5700G
Asus TUF B550-Plus Gaming
Vengeance Corsaire 3600 MHz

My problem is that I tried to use the ram’s full potential and therefore enable DOCP in the Asus BIOS.
The problem is that firstly the change doesn’t apply and I remain at 2666 MHz and the second is that when I restart the PC, it reboots 3 times and shows me a page saying there is an error, making Windows boot impossible.

I still can’t find a solution; I tried updating the BIOS but with no result .

Hoping to find a solution.

Thank you for your help and have a good day

    It’s better to leave your RAM in auto, at 2666MHz there’s no perceptible performance difference anyway, your processor uses an integrated chip that takes its memory from the PC’s main memory. The room for maneuver with this type of CPU isn’t the same as with a graphics-chip-free one.

    Use CPU-Z and post screenshots of the Memory and SPD sections.

    Hi

    Is it normal that your RAM kit runs at this frequency of 2666MHz because this is its JEDEC configuration (table from the 3rd photo; these are the real frequencies, so 1333x2=2666; this one being the commercial frequency)

    If you want to bring the frequency to 3600MHz, you need to choose in the BIOS the RAM profile "XMP" (right column of the table).

    It's found in the RAM settings pages in the BIOS.

    Do not change anything else, and if it causes problems, revert. In any case you won't notice any performance difference (and your CPU won't handle RAM beyond 3200MHz anyway)

    You have the latest BIOS version. Normally your motherboard can handle up to 4600MHz, so 3600MHz should work. There might be several XMP profiles and you’re not choosing the right one. Otherwise, you can try a manual adjustment.

      Hello

      Thank you for your responses. After trying to set the RAM in "XMP" profiles, when I restart my PC it reboots 3 times and an error message "American Megatrends" appears on the screen. I think the tweak doesn't work and I have to reset the BIOS to default to return to my desktop.
      Do you have a solution?

      Thank you for your help.

    Do you save the changes before exiting the BIOS? What is the model of the Corsair Vengeance kit?

      Yes, of course I press F10 to save and exit, and here is the Corsair RAM reference:

      Corsair VENGEANCE LPX 16GB (2 x 8 GB) DDR4 3600 (PC4-28800) C181.35V Desktop Memory Black

    I wanted to see if there were people who had problems with these memory sticks. Indeed, there are, even though for the majority it works without issues:

    https://www.amazon.fr/Corsair-VENGEANCELPX16GB-Pc4-28800-C181-35V-M%C3%A9moire/dp/B07RM39V5F#customerReviews

    If you bought them on Amazon.fr, they refund or exchange easily.

    Hello,
    any idea, we need to see if there is an option in the BIOS that allows choosing whether the memory is managed by the motherboard or the CPU

    otherwise sometimes the RAM or the motherboard cannot overclock without knowing why.

      But that thing doesn't exist.

        Indeed, for many years memory controllers have been integrated into processors

        I had this option on an ASRock. I’ll see about posting a capture for you. (unless I’m mistaken)

        On an Asrock motherboard, to switch between DDR2 or DDR3—Yes, it was possible; they made some combos back in the day, but the memory controller was on the motherboard. Now we have a latest-generation CPU that includes the memory controller built in.

    I don’t recall there ever being a time when there could be a memory controller in the motherboard (MB) and, at the same time, a memory controller integrated into the CPU. In my memory, we moved from memory controllers on the MB to memory controllers built into the CPUs.
