Although the current motherboards have CPU voltage rating marks, depending on the reading software, efforts have been made to provide users with an easy and straightforward way to differentiate between calls VID and VCC.
VID voltage: required, but not compatible at the end
When a user browses his CPU and begins to read the motherboard's statistics, he can encounter two very different situations:
- VID is similar to VCC.
- VID is not compatible with VCC.
The first step to understanding why this happens is to know what they are and how both prices are different and why motherboards display these two values instead of one.
What is VID?
In addition to talking about VID power, we should talk about the VID configuration of the processor or CPU. It means VID Voltage indicator and so does the voltage required by the CPU VRM, this is the maximum height allowed at that time for such conditions TDP or provinces PL.
So also in contrast to the belief that most users have, it is not CPU voltage is useless and therefore it is not acceptable to understand vdroop in such cases. In addition, VID is only understood if cardboard conditions and BIOS / EFA settings are automatically enabled, without any changes.
Any change in voltage said, C says, EIST or similar technology canceled VID. Ergo, said that VID was introduced as part of the Intel / AMD microcode in the processor, so that lower and lower values were set to maintain CPU integrity and security.
What is VCC?
The power of the VCC is very simple, since it is the actual voltage supplied by the motherboard to the processor, which is recorded by the power controller. It is always lower than VID, when they previously understood that we made the correct assumption of Vdroop through the LLC.
Therefore, it is electricity that we have to consider when we have touched on any of the aforementioned sectors (something to do, at least for the LLC), so, it's a much more powerful gas than VID, even if the readings are made by software.
In addition, VCC does not comply with VID parameters regardless of the frequency of the processor, but if they extend for a long time they may block the system, so it would be best to calibrate vdroop and use LLC.
Everything seems to be very beneficial for the VCC as described, but one thing must be taken into account. When we work LLC and as a result of the VID being activated, we don't really know the voltage that every millisecond is brought to the processor (an oscilloscope is required as a result), so, we have to be very accurate in the calculation of vdroop and the LLC value, because the transmitted voltage may exceed the limit set by the VID.
Use VCC instead of its dangers
Suppose you leave the voltage and voltage across the user's hands, which is understood to know exactly what he is doing and how to do it. If we do not have an oscilloscope, it is important that you have a motherboard with rating points manually, when the multimeter is in hand, we can see the actual voltage transmitted and the peaks under load.
Since this is rare and most users are learning VCC from different software, it would be best to use compression programs that lift the CPU load and voltage and voltage requirements more than what the low-end software does. standard load That is, similar software Prime 95 or IBT for example, they exceed the standard load limit that 100% of processors can have, including AVX commands.
So, in the unconscious hands, it is the focus of continuous power peaks that will damage the CPU faster if it has never been done before and in a more conscientious way.
