What is Vdroop on overclocking?

vDroop – the difference between the idle and load voltage.. Generally, you get a higher voltage when idling than when at full load. That’s because it works as a self-protection mechanism to prevent too much voltage surging into the chip and frying it, or not giving it enough power.

What is acceptable Vdroop?

Some people argue keeping a tight Vdroop is good between a 0.02-0.05v drop from Core Voltage, while some have anywhere between 0.1- 0.15v of VDroop.

What is V droop?

Vdrop is the difference in voltage between the BIOS setting and the one reported by the CPU (via CPU-Z). This is caused by some effective resistance/impedance in the circuit between where the voltage is controlled and where it is measured in the CPU. Vdroop is the difference in voltage between idle and fully loaded.

Should I disable Vdroop?

Turning on “without vdroop” control mode will boost the voltage when a drop is detected and might increase stability at high current draws. The down side is when the CPU switches back to idle low power states the voltage spikes and might cause slow long term damage over time.

Should I use Loadline calibration?

When overclocking, there are a lot of tricks to perform and settings to tweak; adjusting load-line calibration is one of those settings that can help maintain a successful overclock. It also goes a long way in ensuring long term stability so you can get on with your work or play and stay out of the BIOS.

What should I set my load line calibration?

0% applies the least amount of voltage, while 100% tends to overvolt slightly under load and heavily while idling; while this can be beneficial for extreme overclockers, you will want to start somewhere in the middle for 24/7 usage. Just like when adjusting core voltage, fine tuning is key here.

What does Loadline calibration do?

Load-Line Calibration, or LLC, is a BIOS setting found on most performance motherboards. It applies additional voltage to your CPU under load to provide more stability while overclocking and compensates for high and low voltage fluctuations, to keep your voltage line to the CPU more stable.

What is LLC in overclocking?

LLC, short for Load-Line Calibration, applies additional voltage, when needed, to the CPU to ensure a more stable vCore under load (closest to what you manually set), and minimize the gap between CPU voltage in idle and load. So LLC is the golden setting when looking for the perfect 24/7 CPU overclock.

Should I overclock cache ratio?

Setting the Cache Ratio at a lower frequency than the Core Ratio can result in lower performance. If this is your first time overclocking, it’s recommended to keep them at roughly the same frequency, though feel free to experiment to see what works best.

Should I sync all cores?

The Pook said: if you want your CPU stock then put it on auto, not sync all cores. sync all cores does what it says, it syncs all cores so they all boost to the same multiplier rather than letting the CPU boost higher when on lightly threaded tasks. it’s similar to MCE.

What should my CPU cache be?

For stability usually people dial Cache ration to about 300mhz less than CPU speed. The Turbo setting doesn’t play any role at this point because you are already over the Turbo speed. If you set CPU ratio to 35 then Turbo speed will increase to 39 when needed and more likely only on one core.

Should I enable C states control?

C state is used for power saving and when you overclock you use the maximum power of the CPU, constantly. So you would not want to use c state. Disable both, also manual vcore always, adaptive might do some adjustments you don’t want to happen. First off an overclocked processor does not use maximum power constantly.

What does vdroop mean?

When you put it under full load, it’d drop to 1.47v. That’s vDroop. The board gives it extra voltage at idle so that when the chip goes into full load it can handle the negative voltage drop without going below the minimum 1.35v.

What is vdroop and Voffset?

That’s vDroop. The board gives it extra voltage at idle so that when the chip goes into full load it can handle the negative voltage drop without going below the minimum 1.35v. Likewise, the voltage upshoot from from full load to idle is protected by vOffset.

What is the cause of vdroop?

So vDroop is caused by the load suddenly increasingrather than the actual amount of power being too high. If I understand correctly, Load Line Calibration keeps an eye on the instructions that the CPU/GPU is about to execute, and signals the voltage regulator preemptively so that it isn’t “caught off guard” by the sudden increase in power demand.

Why do people shoot for a tight vdroop?

People that shoot for a “tight vdroop” as you call it, (I call it just a close actual to requested voltage ) are doing that because they are using a set voltage, or they don’t understand it too much. Vdroop can be your friend when using adaptive voltages, so you can better control low-mid-heavy load voltages.
