Processors

[eduvfx]

so my processor is an r7 5800x it has been showing strange behaviors such as: high temperature, high voltage, high clock, I have a 240mm water cooler but it seems that I have nothing to cool it because it goes out of control with high voltages, it it reaches 96 degrees when I'm rendering, and 145W at peaks, I've done undervolt through the bios but sometimes the PC restarts out of nowhere, the clock reaches 4849mhz, it stays on average at 62 degrees without me doing anything on the PC because the voltage increases automatically , the bios settings are at default, My motherboard: B550m-Plus Asus Tuf Gaming

i need help!

Please see the advice in this thread:

I believe ASUS often enables PBO by default.

The solution for this user was disabling PBO: https://community.amd.com/t5/general-discussions/ccd/m-p/678123

You can also try this method for keeping PBO performance while reducing voltage / temps: https://www.youtube.com/watch?v=dfkrp25dpQ0

Do you recommend using the Ryzen Master curve optimizer?

I would:

1. Set Ryzen Master to default settings and only use it for monitoring.
2. Set your BIOS to default settings to remove whatever undervolt was previously applied.
3. Research the PBO settings in your BIOS and other default "boost" settings Asus may apply on AMD boards. Consider disabling PBO to see if there's improvement. If there is, consider the PBO undervolting method in the linked video.
4. If #3 doesn't resolve the issue, then explore further adjustments using either BIOS and/or Ryzen Master. You'd have to refer to the first linked thread for advice there.
