VDroop Question

[UnaverageVague]

I OC my 7700k to 4.8ghz with a vcore of 1.210 on HWMonitor the voltage reads 1.200 why is that?

 

also why is does it keep switching from 1.200 to 1.216?

LLC (Load Line Calibration) i think. 

 

It will try to keep it close to what you've set in BIOS but may fluctuate depending on power or load. 

 

4.8GHz at a touch under 1.25V is mighty. Test if it stable.

my LLC is set to auto but does having that switch from 1.200 to 1.216 bad? or normal?

If the system is stable it doesnt matter. Its not really bad or good, but the motherboard is trying to save power when possible, along with keep the power delivered to the CPU stable. If your OC is stable, dont worry about it.

so is getting a 1.200v on a 4.8ghz oc good?

Nothing wrong with it. It's just reacting to CPU load or CPU power. 

 

If it bothers you apply a higher level of LLC to combat the voltage drop (Vdroop). Experiment until you find something that works. Although because LLC makes VRM work harder to sustain what you've set in BIOS it can exceed slightly.

Load line calibration can cause your voltage to exceed what you set in the BIOS

 

Load line calibration goes against Intel's design and tries to keep the voltage constant at all times. However, with it turned on, we now aren't guaranteed we'll stay under the voltage that we set in the BIOS. And (as mentioned before) we're putting more stress on our motherboard's voltage regulators by trying to maintain a constant voltage.

it doesn't bother me much as long as it doesn't damage my CPU, so if I managed to get a 1.210v 4.8ghz OC would you have any idea what I can maybe get 5.0ghz to?

The V should be tight not droopy.

Basically if the CPU doesnt need 1.215V, its not going to ask for 1.215V, so it's not necessarily even vdroop in this case. Even though my CPU is set for 1.3V, at idle it will drop to .7V

To start: 5GHz could probably be doable at around 1.35V~  Maybe up to 1.4V depending if you have one of the early 7700Ks.

You're fine man.  I think you're worrying a bit too much.

 

Your voltage under load will continually fluctuate to a degree.   Voltage in Windows via monitoring apps is reported in 16mv increments.  That means you many be seeing 1.2v one second and 1.216 the next even though it's actually only 1.209 or something along those lines.

 

You will never hold a constant voltage when running a stress test like RealBench or the like as the load is constantly varying.  

 

Your LLC is fine and 4.8 GHz at 1.2v is pretty decent for a 7700k.  Not the best or worse so you're doing well.

I'm running realbench stress test right now and it's pinned at 1.200 and has switched is that fine? And yeah I'm just worried about damaging my CPU

How did you get yours to drop that low when idle mine stays at a constant 1.200 or 1.216 in idle

What are you using to monitor voltages? And I have all power saving c states enabled in the BIOS, along with the balanced power plan instead of the high performance one in windows, which all of that is enabled by default, but when overclocking they can be disabled or overridden. But its not abnormal for yours to stay pinned high, it just has to do with BIOS settings you tweaked

That's relieving I do have high performance on, if I were to switch that to balanced would that mess up my OC or will it allow it to drop V when idle?

My 6700k is OC'd and I dont use high performance. It should allow your CPU to downclock and undervolt to save power when not in use, but not affect delivery when you need it
