Whether to use load line calibration depends on your specific requirements.
I have a question about the desired voltage when paired with an LLC setting. I'm using a Gigabyte z270x gaming 5 and a 7700k processor, which doesn't seem very powerful. I struggle to maintain stable 5GHz performance at around 1.35V. Since I don’t currently have a liquid cooling solution, increasing the voltage and temperatures becomes too problematic for me. I’m considering sticking with 4.8GHz, but that’s where my main concern lies.
I can achieve stability at 1.2V, high LLC, or 1.275V with auto LLC, which seems to be low/off from what I understand. I’m familiar with how LLC works, but my question is whether it makes sense to raise the voltage slightly—say around 1.275V—and let it gradually decrease under load to about 1.2V. Alternatively, keeping the voltage lower during normal operation at 1.2V and allowing it to stay close to that level while slightly dropping when under load (though it usually overcompensates and jumps back up).
In my view, it would be better for idle temperatures and chip longevity to run at a lower voltage during idle, rather than overcompensating with higher voltage when needed. I know droop is part of the design to avoid voltage spikes during load changes, but the maximum drop I’ve seen under this setting is around 1.212V, unless it happens too quickly to detect. So again, I’m curious if aiming for a lower idle voltage could be more beneficial overall.
Setting LLC to high effectively compensates for vdroop, the voltage fluctuation during operation. This ensures the actual voltage stays near its intended value.
The voltage readings are satisfactory. I own identical boards and CPUs. At 4.8 volts I've maintained stability at 1.32 with LLC running in turbo mode during stability tests using prime95. The monitoring tools showed a peak voltage of 1.39 and the maximum temperature reached was 77°C. I'm employing a Cryorig R1 universal cooler and CPU delid. With LLC set to auto, the highest voltage recorded during testing was 1.36, but it didn't remain stable when using prime95.
