Safe voltage margin for Ryzen 1600 OC running at 3.75ghz
Safe voltage margin for Ryzen 1600 OC running at 3.75ghz
Variations in the BIOS version and motherboard can lead to a negative offset. You would retrieve hardware information and check the core voltage at idle. Adjust the offset to achieve the desired voltage level. It's generally preferable to keep the voltage as low as possible. Regarding the clocks mentioned, I believe 1.375v or less should be adequate.
I'm trying to overclock my Ryzen 1600 to 3.75 ghz with a voltage offset of 0.16250. Is this acceptable? If not, what should I set the voltage offset to on an Asus Prime B350 Plus motherboard with DDR4-2400? I'm using the same CPU, board, and cooler as you mentioned. I also have higher clocked RAM at 3000 MHz and have reached a stable 3.85 GHz OC with an offset of +0.1125 according to CPU-Z. If I choose a higher offset like +0.1625, I might end up pushing the voltage too high. Vellinious said this is likely the limit for long-term air overclocking, so I should aim for what you're using to maintain stability. My maximum temperature in AIDA64 stress is 80°C, and in games it's around 70°C, which is safe for the stock cooler. I wouldn't exceed that temperature further.

If not, what should I adjust the voltage offset to on an Asus Prime B350 Plus motherboard with DDR4-2400? I’m using the same CPU, board, and cooler as you do. I also have higher clocked RAM at 3000 MHz. Currently I’ve reached a 3.85 GHz OC with an offset of +0.1125, which equals about 1.35 v in CPU-Z. If I lower the offset to +0.1625, I’d expect around 1.4 v. As Vellinious said, that’s likely the limit for long-term overclocking on air. For the clocks you have, try reducing it to what I’m using and you should get stable performance. My maximum temperature in AIDA64 stress is 80°C, but in games it stays around 70°C, which is safe. I wouldn’t go beyond that on the stock cooler. The BIOS changed a 0 to 0.1125 and set it to 0.11250; in CPU-Z it’s fluctuating up to 1.363. That’s normal?
Yes, it consistently exceeds 1.35 v on several occasions and peaks at 1.363 v, which is typical. I'm uncertain but this might be linked to the auto LLC (load line calibration) adjustment. The variation is also expected—it lowers voltage when not required, similar to before the OC. Since you're running at 3.75 GHz, consider lowering the voltage or raising the frequency to align with my OC. Monitor your temperatures and stability during stress tests and gaming. My ambient temperature stays around 18-21°C. I've noticed that for every 1°C rise in ambient temperature, system temps usually increase by about 1°C as well.
When the voltage decreases during stress, this phenomenon is known as vdroop. A low LLC configuration helps reduce the drop slightly and prevents the voltage from falling too much. Conversely, a high LLC setting might raise the voltage when the CPU is under heavy load, though it generates significant additional heat in the VRM. Using excessive LLC is usually not recommended.
