3930K VID now higher for the same clock speed?

post #1 of 8
Thread Starter 
When I had my older BIOS, the VID for 3.8 GHz was 1.241 volts as seen in the following screenshot (ignore the 782 MHz minimum clock speed because I am not sure why that happened and it hasn't happened again)



Now, with the latest BIOS, the VID for 3.8 GHz is 1.306 volts. That is a massive increase.



What would cause something like this? I thought the VID couldn't be changed.

By the way, I've also noticed that my temps are higher with the latest BIOS compared to my older BIOS that reported a lower VID.

The VID will change for a Multiplier based on the LOAD that is on the CPU.

Running 40x Multiplier, the VID will be different running paint.exe or Battlefield 4 as example thumb.gif

So maybe the BIOS now shows the ''MAXIMUM" VID for that multiplier.

When i run a old version of IBT my max voltage is 1.35v VID, the ''new'' version with AVX instructions goes to a whopping 1.42v.

Both of those pics where taken at the desktop.

Secondly, with the older BIOS, the stock VCore detected in the BIOS was 1.2xx volts but with the new BIOS it is detected as 1.305 volts. What would cause this?

One more thing. With the older BIOS, the VID would never get close to 1.3xx volts even when stress testing.

Check if LLC setting was changed with bios update.

LLC settings were auto with the old BIOS and auto currently in the new BIOS. I am a bit of a noob when it comes to LLC settings. Right now, with the new BIOS, LLC reads as +60% and is set on Auto. I can't change the +60% but I can change the Auto setting to Normal, Standard, etc.

Try to change Auto LLC setting and see how will this impact on Vcore value under load condition and overall stability.

LLC should only affect the Vcore not the VID

You're right. The VID can change due to temperature and /or current load. Thank you for the input.
