Maximum safe voltage for Zen+ system
Maximum safe voltage for Zen+ system
The maximum safe SOC voltage for Zen 14nm isn't clearly established. Opinions vary, with some mentioning 1.3V and others 1.25V. I've noticed degradation in IMC at around 1.26V using a multimeter, while HWiNFO shows readings between 1.076 and 1.2V for Zen+ over time. It seems values above 1.25V might not be safe for Zen+. I'm planning to test with a lower input of 1.18V, which I measured as a maximum of 1.249V. These two architectures appear to have different safe voltage limits.
Values above 1.2 seem unrealistic and should be avoided. This also covers zen 1 /+/2.
I aim to build some experience. Most people don’t set inputs like 1.2V or even 1.19V, I used 1.19V and it didn’t work well, so if someone says the safe limit is around 1.2V, it’s likely based on actual readings from your motherboard BIOS or the real voltage at the socket. I plan to try 1.18V this time to check for any long-term effects. Regarding voltage limits, I’m curious—should the maximum safe voltage for Zen 14 nm be the same as for Zen+12nm, or should Zen+ be lower? You’re right it’s not core voltage, so the differences might be more significant.
Generally I prefer keeping things straightforward and consistent across all units. Anything above 1.2 tends to be problematic, unless you're heavily overclocking or aiming for competitive rankings—1.2 is ideal, and 1.1 offers the best performance while still being manageable. Usually a voltage around 1.2 is the sweet spot.
It's understood that nodes size isn't critical here. For 7 nm Zen 2, the safe core voltage max is around 1,325V for 1.45V and 1.45V for Zen 2, which can't be combined into a single voltage. I believe it's best to proceed with 1,18V this time to maximize performance from the integrated graphics.
Wait if it's an apu this is a completely different story The apu is basically connected to the soc voltage Since obviously it gets it's bandwidth from the memory channels just like the imc so it's tied together The more you raise the soc voltage the more it will most likely be unstable I suggest trying 1.15 or 1.1 and then going up from there
this situation isn't matching what I expected. memory performance stays consistent across a wide range of voltages, from 1.1 to 1.3 V (just a slight negative effect on the slowest timings at higher voltages). any increase in gfx voltage always improves things because the display unit loses stability at low voltages when memory is pushed hard—unless it's a serious issue. therefore, raising the SOC voltage consistently benefits my setup.
