Hey there, so I'm messing around with my LLC stuff. On Extreme it shows 1.56 on the CPUV for my FX 6350. The max allowed is 1.55. Does that mean I am .05 over or does it count? It only happens when stress testing. Thanks, TIA!

It's actually high. Set the LLC to medium or auto so you don't get confused. Just watch out for voltage because if you crank up the speed, the current might make up for it in terms of power. I wouldn't aim for that crazy 1.375v to 1.4v range just for a daily driver; usually, lower is better.

You need to know about LLC if you want the answer. Electricity only moves so fast, not as fast as a CPU can ask for it. When the CPU stops asking, the voltage drops in the VRMs because they aren't sending enough right away. Then the CPU suddenly asks for way more and hits instantly. That drop is called vdroop. You get unstable when the CPU needs more than the VRMs can give at that moment. This made LLC necessary. It's a pre-emptive voltage that never turns off, so it adds to the vdroop. The VRMs can then meet the CPU's demands even before the drop happens. Because of this added voltage, they also add to the top of the droop too, so the VRMs might send 1.4v when the CPU asks for load, but LLC adds more so you see vcore at 1.56v, which is what the CPU gets. Extreme LLC isn't needed for most OC builds, except maybe record-breaking LN2 runs. At most you'll ever need medium to high or step down 3 out of 5 from Extreme. That gives enough voltage to keep things stable but not so much that it burns the CPU. For an OC on a 6350, you should be closer to about 1.32v rather than over 1.5v.

I get vdroop. The number 1.56 represents an LLC plus 1.3675 volts. So, when the base voltage and LLC voltage add up to more than 1.55 volts, is that okay? I just don't want to burn anything out...

It's hot right now. Turn the LLC down to medium or auto. Then worry about voltage instead of just speed. Just adding more current doesn't always mean you need way higher voltage for power; sometimes the extra current helps balance things out. For a normal daily use, I wouldn't go above 1.375 volts up to 1.4 volts or even that much total. It's better if it stays lower.
