Voltage was reduced for my CPU somehow raises its output.
Voltage was reduced for my CPU somehow raises its output.
I have an AMD 3600 (no overclock) – this model is covered under Article 34 Duo Esports cooler. Generally, a few days ago I wrote a post because I was worried about my CPU voltage. It usually stayed between 1.39 and 1.4 during gameplay. The main issue was high temperatures, never exceeding 60°C, with an average around 55°C. One suggestion was to lower the CPU voltage, so I searched YouTube for tutorials and followed them. Here’s what I did: downloaded Cinebench, ran multicore and single-core tests, and received the following results – 8868 points on multicore, 1190 on single core; 70°C on multicore, 60°C on single core. I didn’t check voltage in the videos, but since those were before any changes, it didn’t affect me. Then I adjusted the voltage in BIOS under OC Settings: set CPU Core Voltage to offset mode, pressed '-' to subtract the offset, and entered 0.0750V to reduce it. After restarting, I ran the tests again – I got 9170 on multicore and couldn’t run single-core tests. Multicore temperature dropped from 65°C to about 49°C. I further checked voltage using Ryzen Master, which sometimes reached 1.41 or even 1.42. While temperatures were lowered, they didn’t decrease as expected because my temps were already good. I tried lowering the voltage more to extend CPU life, but it actually increased temperatures instead of reducing them. Any advice or suggestions would be appreciated.
I believe Ryzen Master displays the VID instead of the real voltage; the mainboard will deduct 0.075V from whatever Ryzen Master indicates. For accurate readings, use another utility such as HWiNFO64 or CPU-Z, which provide the true Vcore value measured by the voltage regulators.
In the CPU area (the section displaying all CPU temperature readings), there is a "CPU Core Voltage" value measured by sensors. Next to it is "CPU Core VID," which should match Ryzen Master and be slightly higher than the first number by your set offset. Most motherboards also feature a "Vcore" sensor in the mainboard part, intended to reflect the same voltage but may differ by about 0.01V.
You've got the .0750V adjustment. The sensors aren't extremely accurate, which is why it shows .0770V, but that's still within acceptable limits. The VRMs can only maintain a certain voltage precision anyway. It seems your undervolt issue is resolving properly.
