Ryzen master probably used max or close to max -30 value for undervolting, you can find PBO in bios and set curve optimizer to lower value like -15, once you boot just disable it in ryzen master and delete that crappy program lol. Most cpus can get -20, you can try -15 first, use program like cinebench or prime95, for 15-20 minutes to make sure it doesnt crash Answer from Deleted User on reddit.com

r/AMDHelp on Reddit: I tried optimization curve, and now my pc keeps restarting
September 7, 2025 -

So in the amd ryzen master app, i tried the optimization curve on all cores. After waitingnfor an hour for it to be fully optimized, i applied it. My pc restarted and then everytime i got into my home windows screen it will just restart again and then the blue screen came out in which to choose F1, F8 or Esc. Tried everything on that blue screen but nothing works. What should i do now? I cant even open up ryzen master to disable the optimization curve. CPU: Ryzen 7 5800 X RAM: 32 GB DDR4 3200MHZ GPU: RX 9060XT 8GB PSU: 600W MOTHERBOARD: AORUS X570I WIFI

r/overclocking on Reddit: Used ryzen master curve optimizer and my PC keeps crashing
December 3, 2023 -

I have a Ryzen 7 5800x and a Aorus Gigabyte B450m pro wifi motherboard, Windows 11. I recently upgraded to the new CPU and have been using it for a couple weeks. I decided to use Ryzen Master to use to auto optimize for the CPU. It took about an hour and I think it blue screened at one point. But when it was complete I hit apply and it went to rest the PC. When it did, the Aorus screen comes up like it it's booting and the blue screens and says it has to restart. When it restarts, it says its going to repair but then crashes again. It just starts doing this over and over. I tried putting the bios into safe mode but that didn't do anything. Please someone help. I'm fairly new to this stuff.

r/overclocking on Reddit: Ryzen master requiring a reboot for minor changes
December 4, 2022 -

Hi guys,

I just build a new setup with a 7950X and I'm loving it. To make it even better I'm trying to do some manual curve optimization.

Sadly, every minor change will force me to reboot so that Ryzen Master can apply it. Since a reboot takes well over 3 minutes and I'm trying to curve optimize a 16 core CPU this is beyond tedious.

Does this sound right? Does YOUR ryzen master require you to reboot on every minor voltage offset change in the curve optimizer? Or should I send a strongly worded letter to ASUS.

Auto curve optimization doesn't work either, it chokes on itself at the end and bluescreen every time it retries one of the final steps, never finishing (and forcing me to abort).

I did read a bit about just bumping the bclk a bit and/or increasing the max turbo offset in PBO, but that causes instabilities really fast.

I'm using it with a X670E-I GAMING WIFI, EK 280MM D-RGB AIO and KF552C40BBK2-64 (though I doubt latter ones are really relevant).

Edit: If anyone cares I'm writing down some of my thoughts.

Frankly the bios of this board sucks donkey ass, there's just so many things going wrong I'm honestly baffled.

  1. Allowing the bios to set enhanced PBO means setting everything to 1000, but this confuses the PBO algorithm so much that it stops boosting altogether (wtf lol).

  2. CPU voltage offset is beyond broken. Setting a positive offset is actually a negative offset. +0.05V means -0.05V and this is reflected in all readings (Ryzen Master, HWinfo, etc.) and reduces the max turbo. Setting a negative offset is actually a positive offset and this is reflected everywhere. However, this confuses the PBO alghoritm and causes it to reduce the clockspeed similary as it would've been when increased. This effectively means I cannot change the voltage as increasing it will decrease it and decreasing it will increaste the voltage but decrease the clocks. Wtf lol

  3. Setting a negative offset in PBO V/F curve voltage per core works very bad. -5 on my highest performance core was already too much, -3 seems to work OK so far, but that does almost nothing lol.

  4. By default ASUS always memory trains, regardless of what you do, causing moronic boot times unless manually disabled. ASUS thought it was a good idea to hide this option under memory timings. Thanks @planes01.

  5. No option for ECLK asynchronous yet explicitly listed in the bios manual and bought for that reason. ????

There's probably some more shithousery, but I feel like I listed the most important ones.

r/overclocking on Reddit: Amd Ryzen Master : Setting curve optimizer mode makes my system unstable...why?
January 5, 2023 -

I have a ryzen 5600 + rx 6600 + silverstone ET750 gold PSU + ID cooling se-242-xts cooler. I turned on PBO in the BIOS and auto OC in ryzen master, everything works fine and its stable in prime95. But if i set curve optimizer mode to "all cores", the system becomes unstable, fails prime95 tests and randomly restarts by itself.

This happens even if i spend 32 minutes letting the utility test the settings (which it then claims is fine, but results in an unstable system).

Does anyone know why this happens or how to fix it? Not sure what this curve optimizer mode is exactly. I assume it means how the CPU speed ramps up in relation to voltage?

Theres no overheating, even during prime95 stress tests the highest temp i saw so far was 67 degrees celsius, voltage with curve optimizer mode averaged 1.065v, without curve optimizer, it averages higher, about 1.085v.

r/overclocking on Reddit: PC reboots after messing with PBO and curve optimizer
October 29, 2022 -

So my pc reboots sometimes while playing games. It doesn't do it all the time and it doesn't do it necessarily after the same amount of time gaming. My guess is that my overclock isn't perfectly stable, even though I ran OCCT a few times and nothing showed up (the longest I ran it was 1 hour). Either way, does anyone here know if upping or lowering PPT, TDC or EDC might help stabilize it ? Also, I managed to put all cores to -25 on the curve optimizer (except for core 3 that doesn't seem to like going higher than -15). My pc seemed to be running fine. I could do an all-core and single core cinebench run with no crashes, but because of the occasional random reboots, I upped it to -20 but the reboots still happen. I'm wondering if that could also be the source of my problem.

I have a 5700x with PPT at 130 (stock 76), TDC at 80 (stock 60) and EDC at 90 (stock 90)

Thanks ! I'll keep messing around with it, and probably run an overnight occt test, but I'd appreciate if someone that has been through this could give me a simple answer.
