Hi, your Ryzen 5 stock cooler is not performing well and struggles with the CPU's auto overclocking, reaching temperatures as high as 93 degrees. After adjusting the MSI BIOS settings and setting the CPU RATIO to 3.6, I explored the CPU Core Voltage options—OFFSET MODE, OVERRIDE MODE, and AMD OVERCLOCKING. I currently chose the Override mode, which locks the core voltage at 1.25V. Is this acceptable? Should I consider a different setting? Thanks for reading this detailed post. (Cinebench r15 score -1375-1413)
No, it's not necessarily bad. Everything should be functioning properly and at low temperatures.
Let me share what occurred. I purchased a B450M MSI motherboard, a Ryzen 5 3600 CPU, and a few ADADA XPG 3200 MHz RAM sticks with 8 GB each. After launching and playing a Battlefield 1 multiplayer game, the CPU temperatures reached 93 degrees Celsius. I discovered that AMD's Precision Boost Overdrive was pushing the processor to 4100 MHz at a voltage of 1.450V, which is too high for a CPU with a 95 TDP rating. I tried adjusting the CPU RATIO in MSI BIOS to 37.00 and setting the core voltage to 1.25V. However, whenever I changed the core voltage, the system would prompt me to select a mode, which I had previously mentioned. I currently set it to override mode, but it remains locked at 1.25V whether idle or under full load. This is causing concern, and I need your assistance. Could you explain these modes and whether keeping the voltage constant at 1.25V will affect my CPU's performance in the long run? The temperatures are now between 80-83°C during maximum load, and the Cinebench r15 score is around 1450. Thank you!
Unfortunately, MB doesn't offer a direct voltage setting mode where you can adjust the voltage to your preference with LLC (Load Line Calibration) adjustments. The "OFFSET MODE" allows you to set a small deviation from the auto-generated voltage, typically between 0.01 and 0.1V. For example, if the BIOS sets 1.2V and you apply an offset of 0.1V, the CPU will maintain around 1.1V until it reaches the required level. The "OVERRIDE MODE" simply enforces the BIOS's minimum voltage requirement for the base clock. I'm not sure what the exact meaning of "AMD OVERCLOCKING" mode is, but it likely pushes voltages even higher. An increase to 1.25V won't harm your CPU, as AMD states that up to 1.525V is safe for first and second generation Ryzen, provided temperature remains under control.
