Overclocking: Moving adjustments from Ryzen Master to BIOS
Overclocking: Moving adjustments from Ryzen Master to BIOS
Hello,
I'm exploring a minor overclock for my Ryzen 5 3600. I'm currently using it on an Asus Prime X570 Pro with a Noctua NH-U9S cooler. Initially, I noticed elevated temperatures during idle and under load (around 50°C at idle, up to 85°C under load). Looking online, I found PBO and decided to disable it, which slightly improved the temps (only a 5°C drop under load). At that time, I set the core multiplier to 38.00 (3.8Ghz) in the BIOS. This adjustment lowered idle temps to about 30°C and load temps to 60°C, which was satisfactory.
Since then, several BIOS updates have addressed many of these temperature concerns. Now, I’m observing 75°C under load with auto mode enabled (PBO still off). The R5 3600 has the capability to reach up to 4.2Ghz from 3.6Ghz. When I left everything on auto and only adjusted PBO, it boosted to 4.0Ghz. Research indicated that most CPUs expect at least 4.2Ghz for this model.
I experimented with BIOS settings, starting with the core multiplier. Setting it above 4.0Ghz caused the system to fail to boot, regardless of other settings or whether PBO was on or off. I then explored CPU voltage adjustments using Ryzen Master. Using RM, I achieved a stable 4.2Ghz at a core voltage of 1.2V. The RM profile passed stress tests and performed well in Cinebench R20 and handbrake encoding, with temperatures around 75-77°C under load.
I attempted to replicate these settings in the BIOS—setting the core multiplier to 42.00 and VDDR CPU Voltage to 1.2V—but the system still wouldn’t boot. I’ve tried increasing the voltage to 1.3V, which seems closer to recommendations but results in higher temperatures (up to 80-87°C under load), which I want to avoid and keep near 75°C as with RM.
My main question is: what BIOS or Asus software settings allow the system to accept a voltage of 1.2V while maintaining low temps and stable performance at 4.2Ghz?
So here's why nothing is working out for you.
Ryzen's default voltage peaks at 1.45v. This is normal and safe operation, due to Ryzen's silicon monitoring software that makes sure these voltages don't degrade the CPU below it's specified lifetime.
Manual voltage DISABLES this silicon monitoring software, which is why people are now believing 1.2 to 1.25v is the max safe voltage for 3rd gen ryzen, but even that could be too high due to the 7nm architecture.
Getting to 4.2 ghz on a 3600 on ALL cores is very hard, i've tried it myself and failed. The best you can do is use an offset voltage and run PBO and use AutoOC to increase the frequency.
Basically overclocking 3rd Gen Ryzen is useless and will not benefit you at...

Basically overclocking 3rd Gen Ryzen is useless and will not benefit you at all. The performance difference is usually a negative one or equal to stock operations. I've looked at tons of 3rd gen OC material, and have failed to find one that can reliability equal or hit a 3rd Gen Ryzen's Boost clock at SAFE voltages.
Hi, thanks for your message. Could you clarify when you mean 1.2V would be too high? Are you referring to a high or a low value? This comes from your initial mention of the default peak voltage being 1.45V.
I also wonder if you're asking about the actual meaning of "too low" versus "too high." Do you have any idea what specific settings Ryzen Master changes? If I adjust the clock speed to 4.2Ghz and the voltage to 1.2V, it should run smoothly in Cinebench and Handbrake encodes. However, if I try the same settings in BIOS or with Asus overclocking software, the system crashes immediately. This suggests that RM might not be reporting the correct voltages or applying them properly, which is unusual given its good reputation as a monitoring tool. It seems the peak voltage setting in the BIOS might actually be different from what it shows.
Yeah 1.2v could be too high, i mean't high not low. I mean, personally, I think it's fine, however i've looked everywhere for a solid max manual voltage for 3rd gen ryzen and there isn't one found yet.
I see so only in RM will 4.2ghz at 1.2v work, huh interesting. I have no idea why that is the case, but if that is rock solid stable with things like OCCT, i'd just use Ryzen Master for your OC.
Hi, thank you for reaching out. Here’s an updated version of your message. I’ve made some adjustments while keeping the original meaning and tone intact.
