LLC and Voltage Overshoot?

The figures showed a 0.02V overshoot, which is nothing, and I assuming was not the reality of overshoot for heavily overclocked chips at the time. Is this still a concern these days? And if so, is there any way to estimate the amount of overshoot? (ie, comparing idle voltage vs LLC off load, and using that difference as an estimate to overshoot voltage if idle voltage = LLC on load).

Just pick a max vcore your comfortable with then play around with your overclock and settings to keep the max vcore under your comfort zone. It's trial and error and best to monitor with something that will show min and max vcore, temps, etc. Most of the time the overshoot will happen coming of load or between load cycles. LLC depending on settings can make overshoot better or worse dependant on the settings and the MB's abiltiy to controll voltages.

I try to stop at 1.4v's for 24/7 but my rig is water cooled so I don't worry about temps. My chip has been up to 55x at 1.57v's and lives to tell about it. I think Idontcare posted he once pumped 2v's plus in one of his chips with a Oops moment and it lives to this day still.

The article is somewhat dated but still would apply to modern chips I'd guess.

With SB try to stay within 1.3 for 24 7 and if you have h100 or something then 1.4 max

Just aim for the LLC setting that keeps you as close to the voltage set in your bios and you don't have to worry about spikes or overshooting much, if at all, as you likely won't need extreme LLC settings for a decent OC. If you DO need extreme LLC you definitely need to pay closer attention though.
