Hello there



I recently updated my bios, and everything was going smooth. Until I went into my bios, and saw that my CPU vcore was waaaay higher than I had set it before, obviously because my BIOS was now reset. So I changed it back, to where I had it before at 1.180 vcore. Tried to run a game, and everything frooze. In order for the system to run, I now have to have it at 1.260. This obviously affects temps. Why is that? Why is it that I need to increase vcore after this update?



CPU: i7 7700k

Motherboard: Gigabyte Gaming K3

BIOS version: F9
 
Solution
Possible you had Load Level Calibration enabled, that allows a slight uplift in voltage if cpu requires it, so you old settings would work with an automated voltage boost, while new settings don't need it, but both running 1.26v.


If your Overclocking then you do have to increase VCORE to maintain stability under load and probably why your game crashed. When updating Bios your settings are brought back to default.
If your not Overclocking and stable at 1.260V then that should be OK and should not raise Core temps significantly.

If your going to make changes in Bios then make sure to understand the consequence of what will happen especially with Core Voltage settings.
Bios updates are done to provide better stability and probably why the F9b update defaults Vcore to 1.260v.
 


Mate the problem isnt running it stable, before the BIOS update I was able to run my CPU stable at 1.180vcore. Now, I have to run it at 1.260 in order for it to be stable. I was simply wondering why that is, what made the bios update require more voltage from my CPU.
 
There are two determinations, One is VID which is the core voltage for a specific processor as set by Intel and Vcore is what the end user sets and controlled by software essentially.
Why exactly your Vcore has changed you will have to take that up with Intel as all VID voltages are the same for the same CPU. I would not concern yourself too much as long as your stable and temps are in check.
Ideal temps are 10-15C above ambient room temperature and 60-65C under load.
 


Well there's deffintly a change in the voltage, I can see that in the temps. However, perhaps the CPU needs more voltage because it's working more now (protecting from spectre) ?
