Thanks M440 - as mentioned above I was able to get a stable clock set @ 6400.

Good news,

Yesterday I have started looking a bit into the memory adjustments in order to achieve greater speeds. Apparently these modules come from different sources. If you are lucky like me the modules contain SK Hynix dies. Which also seem to be fairly stable and robust.

Long story short. With a few adjustments I was able to run stable at 6400 MHz. Notably UCLCK = MEMCLCK, a memory controller (AMD Infinity Band) clock of 2133 MHz and a main voltage (I believe it's VDD) of 1.35 V took me there. Also, I updated to the latest BIOS v 2.10 which includes an updated AGESA rule set.

I may push a bit more on the frequency side next. But I am already very happy with that. Or, as a second step, play with actual timings. ]]> Fri, 05 Apr 2024 14:43:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=32820&PID=116691&title=b650-corsair-vengeance-ddr56400-64gb-boot-loop#116691 https://forum.asrock.com/forum_posts.asp?TID=32820&PID=116534&title=b650-corsair-vengeance-ddr56400-64gb-boot-loop#116534 Author: biosbandit

I found someone with an AMD system and this memory, working at 6400 (apparently) on Amazon reviews.


Therefore, I've decided to order it and see how I go

I may be content with 6000 CL30 if it can do that.

My intended processor is a 7950X3D and I'll be using the onboard GPU. (So I'm probably very unlikely to achieve 6400 to be honest)

In the BIOS you should see an option for voltage adjustment. You may find if you select 6000 again and increase the voltage slightly (very slightly) it may start working.

Hi biosbandit,

The state as of now is that I was able to have a stable system going @ 5800 MHz as of now.

Please keep in mind that I have absolutely no clue about voltages and the different settings I could apply in that regard. So chances are that running them at the suggested clock speed of 6400 MHz is possible. I just have not figured it out - yet.

In Debian Sid a dmidecode provides me with this information:

I would love to learn more about what could be done to improve stability while going further towards the 6400 MHz.

Which CPU are you using?

thank you for letting us know,

As this system has just been setup and everything is out of the box, is there something that you would recommend taking a closer look at? Or certain settings that I should apply? I greatly appreciate your help.

Nothing if you plan to run the setup at stock.

If you like tuning you can undervolt the CPU (PBO2 Curve Optimizer). ]]> Thu, 28 Mar 2024 13:02:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=32820&PID=115745&title=b650-corsair-vengeance-ddr56400-64gb-boot-loop#115745
