Memory XMP profile not loading.

[RicardoRomero]

Hello Community.

 

This is my first time in a forum, I don´t know if this issue that I have was already posted, if it was let me know where it is.

 

I just bought a Ryzen 7 3700x paired with a ROG STRIX B450-F GAMING II and a 16 Gig corsair Memory rated at 3000 Mhz CL 16 -20-20-38.

 

I installed everything and set the DOCP on the BIOS to match the rated speed and timings of the memory, I saved the changes and rebooted the PC but, it failed to loads that profile, I go into the BIOS again and

it still set to DOCP 3000 Mhz 16 - 20 - 20 - 38, but the speed is 2133 Mhz.

 

I increased the speed sept by step and the maximum that it can go is up to 2733 Mhz, more than that and it fails.

 

My question is there any setting that I am missing? or the MoBo will not allow me to go that high?

 

The MoBo was updated with the latest BIOS version from this year.

 

Memory info

CMK8GX4M1D3000C16

ver. 4.32

3000Mhz 16 -20-20-38 1.35V

 

Your help is much appreciated

Try 2993 not 3000.

Manual voltage 1.4v.

Set the all timings auto.

You need to make sure that your memory modules are installed in slots DIMM_A2 and DIMM_B2. You'll encounter stability issues with DOCP if you're using slots DIMM_A1 and DIMM_B1. See page 1-5 of your manual for a visual representation of slot configurations.

 

If this doesn't help, keep in mind that your memory kit is not on your motherboard's Memory QVL.

I will check the DIMM positions. And yes I didn´t see the part number in there, so that means that I am losing performance?

Thanks both of you for taking the time to help me

You listed the part number as CMK8GX4M1D3000C16. Modules being listed on the QVL generally signifies that they will run at rated speeds with a preexisting DOCP profile. Using memory not present on the QVL may require more trial and error to reach rated speeds.

You got to increase the voltage.
