If you check the ivy oc link above, you'll see that my proc is so-so tongue.gif

Coz many use less vcore than mine at similar oc

Gotcha, thanks for the info. I'll definitely be testing with some games as well biggrin.gif

What settings are you using with IBT btw?

that voltage may be higher than 1.24v that's why the temperatures seem to be on the rather warm side

Crap... didn't know there was a bug. I'll have to look that up. Is it really bad?

I'm using the very high test, since I only have 8GB RAM.




btw, I edited my previous post, Turns out I'm using 1.175 vcore set in bios, while cpuz & hwinfo read 1.152 V tongue.gif

The setting in the BIOS or UEFI never ends up being the actual voltage that powers your CPU. First, you have vDrop. VDrop is the voltage that you see while idling, but only if you're using a fixed voltage and also only if it doesn't drop down for power-saving. Then you have vDroop, which is when the voltage droops down under any kind of load.

 

So, your voltage setting in the BIOS or UEFI is only for your information - no one else needs to know and it doesn't help anyone to know it either. Always go by and report what software like CPU-Z tells you. However, if you have a motherboard that's known to get inaccurate voltage readings, then it's my understanding that there's nothing you can do outside of using some kind of a physical meter device.

yeah, thx for the insight. I'm setting the vdroop 50% in bios & all c state off, in heavy load the vcore is just slightly reduced. And I don't have any of metering device tongue.gif

You're welcome!

 

I'm not saying you need a metering device of some kind, but I know that some motherboards like those ASRock boards don't really have a way to see the actual core voltage - even if it looks like you're seeing it in software like CPU-Z. For those motherboards, I think the only way to see the actual voltage is by using some kind of a meter - like a Digital Multimeter I guess.
