Undervolting R7 2700 on Asrock motherboard

Recommended Posts

Posted · Original PosterOP

I want to undervolt my CPU. Should I use Ryzen Master or the BIOS settings? I've tried both and I'm not sure either of them are working properly. First I used BIOS to lower the voltage down to 0.96 but Ryzen Master still shows more than 1V in the monitoring panel. Then I used Ryzen Master and it apeared to be working after the first reboot but now it's back to 1+ V. Any advice is welcome

software monitoring is never 100% accurate so I wouldn't worry too much about that. Can I ask why you want to undervolt this cpu out of interest

I'm using a very basic motherboard (Asrock B450 HDV R4.0) and I think undervolting might help with overall system stability (turbo frecuencies, thermal performance on the CPU and the VRMs) until I can get a new board.

Oh I see sorry, you shouldn't have too many issues as the 2700 is an extremely efficient chip. how is your cpu responding to stress tests at stock? are you dropping in frequency?

Arent the VRMs the same on that board as the ASRock B450 Pro4?  If so, not sure what you mean I put mine through the paces and there is no issues (8 core 16 thread 1.4vCore)?  I also have great airflow (and a custom loop) so temps aren't an issue at all (for CPU or VRM) - are your ambient and actual inside the case temps perhaps a part of the stability problem?

Everything seems fine enough but on my first run of Cinebench R20, all cores stood at 2.9 GHz instead of the 3.2 GHz base clock, in the second run it was like 3,15 GHz and Ryzen Master shows that the current from the board to the CPU is max out. I just want to optimize things a little bit, I can definetily use the system as it is right now.

You should use voltage offset in the BIOS after a clear CMOS. I dont like using Ryzen Master because BIOS is more reliable and Master overrides BIOS settings.

No it's not the VRM on the Pro4, it's two thirds of the Pro4.with no VRM heatsink. In other words, what you're supposed to use for a Zen based dual core office work machine.
