VCCSA offset mode required?

Hey folks. I've got a RIVE/3930K with a mild overclock, running at 4.2 (1.24V). I'm using SpeedStep, hence I've got my Vcore set up in offset mode. My question is...do I need to set up VCCSA in offset mode as well? I've read some posts about limits on voltage deltas between Vcore and VCCSA being .3V, but while my Vcore fluctates between .79V and 1.24V, the VCCSA is staying pretty much static (on AUTO). Anybody have thoughts on this. Everything is rock stable, but I'm a little concerned I might inadvertently be doing some long term chip damage here.

I would not worry about this. The Vcore only changes when the processor is under light loads. The tip about keeping VCCSA within a delta of Vcore is really about stability when the memory bus and processor is pushed hard. The processors are designed with dynamic Vcore in mind while VCCSA remains static, so no issue if the system is stable.

Thank you both! No worries then. Back to enjoying my RIVE 😄
