PSA: Don't use Ryzen Master for memory overclocks
Dunno why people use it for anything other than confirming your timings/PBO limits have applied properly, or checking if your cores are entering a sleep state properly There's been so many reports of it screwing up OCs over the years that it makes little to no sense adjusting settings in it More on reddit.com

PSA: Do not use Ryzen Master to set Memory OC and Timings. If it screwed up your BIOs, reflash to fix.

Ryzen Master simply sets the memory timing settings within the AMD overclocking portion of the maze of settings. Your motherboard likely has its own section for memory timing settings, its own section for overclocking, it's own auto overclocking stuff, etc.

You just need to dig into the AMD overclocking settings section and reset the timings. Or turn off the the AMD overclocking entirely. The AMD overclocking stuff overrides the other settings on the board.

Should I use Ryzen Master or BIOS for overclocking?
Ryzen Master is a great tool for beginners looking to dip their toes into overclocking. It allows you to adjust CPU core multipliers, voltages, and even memory timings in a Windows environment without entering the BIOS. However, experienced users suggest using Ryzen Master for initial testing and then applying the final settings in the BIOS. The BIOS provides more control and avoids potential conflicts or instability that can arise from software-based overclocking. Additionally, BIOS settings are persistent and less likely to be affected by software updates or OS changes.

What are the advantages of using Ryzen Master for monitoring my CPU?
Ryzen Master offers detailed real-time monitoring of core temperatures, voltages, clock speeds, and power usage across individual cores. Some users prefer it over other tools because it provides accurate telemetry specific to AMD Ryzen CPUs, including visibility into metrics like PPT (Package Power Tracking), TDC (Thermal Design Current), and EDC (Electrical Design Current), which are crucial for understanding performance under load.

Why does Ryzen Master require a reboot after applying settings?
Ryzen Master needs to reboot the system to apply changes because it modifies low-level hardware settings that cannot be altered while the operating system is running. This behavior ensures that the new configurations are properly initialized during the system startup process. However, some users find this inconvenient, especially when making frequent adjustments. Personalized Performance AMD Ryzen Master provides for up to four profiles to store custom clocks and voltage adjustments for both the Ryzen CPU and DDR4 memory. You can park cores and adjust memory timings, too. System Monitoring Acc

r/Amd on Reddit: PSA: Don't use Ryzen Master for memory overclocks
June 16, 2020 -

Just a friendly reminder from someone who just spent a day trying to fix their bricked PC. Ryzen Master is probably the worst way to do a memory overclock. Bricking has happened to others before and it's still happening:

https://www.reddit.com/r/Amd/comments/chytg3/psa_do_not_use_ryzen_master_to_set_memory_oc_and/

As you know, most mobo BIOSes have a feature that falls back to best last know config on errors. What Ryzen Master seems to do is leave a config file that overrides the mobo BIOS, completely ignoring the mobo's fallback feature and rendering a PC bricked on a bad OC. The only thing that fixed it was flashing a new BIOS using the MSI USB flashback port and button. If I didn't have that feature, I'd be RMAing my board right now.

I consider myself lucky... You might not be!

r/Amd on Reddit: PSA: Do not use Ryzen Master to set Memory OC and Timings. If it screwed up your BIOs, reflash to fix.
July 26, 2019 -

Long story short, if you set a memory oc and adjust timings in Ryzen Master, it will override your BIOs settings and for some reason can't be undone. I just spoke to another user who it happened to.

Once you use Ryzen Master to set memory settings, you're pretty much stuck with it. If you notice that you can no longer set memory settings in your BIOs, a quick fix would be to reflash your BIOs to the last update you were using.

Can someone explain to me how this could have happened?

I set memory clocks in Ryzen Master to 3800 Mhz just to test it out

Very lengthy post of what I tried to do exactly that didn't remedy the issue: https://www.reddit.com/r/Amd/comments/chytg3/psa_do_not_use_ryzen_master_to_set_memory_oc_and/ev1pm1c

  1. Computer booted, memory fabrics weren't 1:1 so I decided to set everything to Auto and go back to my original settings

  2. My memory in my BIOs reported 3800 Mhz... This was weird, why is Ryzen Master affecting what my BIOs is reporting. I clear the CMOS.

  3. My memory defaults to DOCP settings. I decide to manually set my clocks and timings back to what they originally were. Rebooted.

  4. Memory clocks are back to what Ryzen Master had set them too! 3800 Mhz, CL 16!

  5. Rebooted, tried to uninstall Ryzen Master, reinstall it, set things to default, nothing was working. 3800 Mhz remained in my bios! Even clearing the CMOS did nothing.

  6. A u/Fbach recommended I reflash my BIOs to fix the issue. I reflashed my BIOs and was finally able to set my RAM timings again without them going back to what Ryzen Master reported.

How was Ryzen Master able to set my ram timings inside my BIOs? How did it continue to override what I applied in my BIOs manually?

Shout out to u/Fbach for the solution.

EDIT: Added more detailed information on what happened.

The CPU overclocking parameters will be returned to stock operation through a system power cycle (Windows Shutdown, then re-starting). System memory overclocking parameters and operation are persistent through a power cycle and can only be changed from Ryzen Master or within the BIOS Setup.

Hi LilCalico, This is Ramesh.

AMDRyzenMasterDriver.sys is part of the AMD Ryzen Master utility which is used for overclocking the CPU. The Memory integrity feature in Windows is blocking the vulnerable driver from loading, hence the error message.

You can uninstall the AMD Ryzen Master utility via Settings → Apps and Features.

If you need it later to overclock the CPU, you can download the latest version from the AMD site.

AMD Ryzen™ Master Utility for Overclocking Control: https://www.amd.com/en/products/software/ryzen-master.html#features

However, some users suggest not to use the overclocking tool, especially on laptops. Please see this thread at the AMD site.
