Basic inquiry on adaptive voltage
Basic inquiry on adaptive voltage
The question asks about the distinction between two calculations and whether an offset is needed. It seeks opinions on stability differences and asks for a preference. The tone remains direct and concise.
Eximo:
Is a voltage without any offset a constant voltage? What motherboard and CPU are we talking about? It really doesn't matter which one you use—it's just an overall question that applies to any board.
I'm using an Asus z170-a with an i7-6700k.
I'm trying to clarify this for you. In the BIOS, when overclocking, you can select manual, offset, or adaptive voltage. I chose adaptive mode so the voltage adjusts based on CPU speed and the power needed to maintain frequency.
It's really important to consider how voltages change depending on the chip type, frequency, and cooling limits. Based on the situation, I could propose an alternative solution. Every motherboard maker has its own terminology. For Haswell systems, I'm more comfortable with Skylake than with ASUS. Adaptive voltage seems to boost the core voltage once the stock multiplier is surpassed. This effectively defines the upper voltage limit you'll encounter. A value of 1.3 plus 0.1 becomes 1.4 when the multiplier goes over 42 (assuming a 100Mhz BCLK). Offset voltages widen the CPU's voltage range across all multipliers. This is usually applied when power-saving features need to activate.
There seems to be a misunderstanding about my English skills, as I was searching online for the answer but couldn't find a clear solution. Picture this: you require voltage to maintain your clock steady, so you introduce voltage in the BIOS. In my situation, I managed to keep the clock stable at 4.6GHZ while supplying 1.275V.
I’m not facing any stability problems; what I wanted was to grasp why an offset is important in adaptive mode. My settings in adaptive voltage mode are set at 1.250 plus a 0.025V offset, which ensures that when the load increases to 100%, the voltage rises to 1.275V. I attempted adjustments like 1.220 plus 0.055V or 1.275 plus a tiny amount, but as long as the total voltage stays at 1.275, my clock speed remains consistent.
I completely comprehend how manual and offset modes function with fixed values, but the adaptive mode is still unclear. Specifically, I need to know what the exact offset value should be in adaptive mode.
For instance, if I set an offset of 1.275V plus a small amount while the CPU load is at 50%, it would require 1.020V. Alternatively, with 1.250 plus 0.025, at 50% load it would drop to 1.045V.
I’m unsure if my reasoning is correct, but I’d like to understand precisely how offset affects voltage control in adaptive mode. It might relate to power-saving features, or at least I want to know the advantages and disadvantages of having an offset in this setting.
I don't think there is a point to using Offset with Adaptive mode. If you are using Offset mode you will increase the voltage at all points in the CPU's range. If you use adaptive, you are only increasing it at the top end when the CPU is loaded. If you use both, I imagine the top of the voltage/frequency curve would stay the same, but the rest would increase with the offset value.
Eximo:
I don't see much benefit in using Offset with Adaptive mode. When you're in Offset mode, you raise the voltage across the board for all points in the CPU's range. But if you switch to Adaptive, it only boosts it at the highest levels when the CPU is busy. If you combine both, I think the peak of the curve would remain unchanged while the rest adjusts with the offset value. Yeah, that was a good idea.
