How do I put a specific voltage?
How do I put a specific voltage?
Hello. From the photo you shared, it looks like the system only offers Dynamic Vcore up to 0.300V and it fluctuates a lot. There seems to be no stable setting for a fixed voltage. Could there be a way to use standard BIOS options to set a consistent voltage without instability? Also, could a BIOS update help? I’m a bit behind in updating (I think I have BIOS version F41). My motherboard is a Gigabyte B450M S2H.
Unless you have a good reason, which it does not seem like you do, you should leave all of those on auto. It is normal and preferred behavior for the voltage to go up and down as the clock speed goes up and down on modern CPUs. You should not be trying to set a fixed voltage unless you have a very good reason. Furthermore, as @xg32 says. "+.252" is very unsafe. You are going to destroy your system if you don't know what you are doing.
My peak voltage reaches 1.25 and stays there. It seems that 1.25 is within a safe range.
You clearly aim to increase the voltage further because the current reading at 1.25V is acceptable. The specifications should support this adjustment.
Try adjusting the voltage a bit higher and see how it performs. At 3.8 GHz it works, but pushing to 4.00 GHz might need more power than the dynamic core supports. Experiment carefully.
We've gone through the official guide, which seems you skipped, and it shows just how bad your CPU is under that voltage. Remember, +0.100 is already problematic. Going up to 0.250 could wipe it out within weeks.
