That's exactly what I was worried about and my unfamiliarity with things makes me nervous.

Yeah. I didn't notice the idle CoreV. I do wonder how much the processor actually needs to run 4.4....

Maybe set to Override, enter 1.29V on CoreV and see if it passes a test...

I'm still kinda new to Overclocking/tinkering with BIOS, is this basically just manual mode, setting 1.29V and then that means it will run at 1.29V at all times idle/partial load/full load?

I get that, although you shouldn't be scared of instability, you cant break anything unless you try to force a lot of volts through the chip, like 1.5V + which you can only do by entering it in the BIOS yourself accepting it and restarting the machine anyway. To low volts will just cause instability, which might need a Windows re-install if youre unlucky but nothing more drastic.

Honestly in your situation I'd return the chip, or contact the seller and query it at least.

It takes time to overclock/undervolt succesfully and stably but it really isnt that hard to do it basically, spend a bit of time reading the guides. As I said I cant tell you anything that isnt written far more clearly by people with a much better understanding then myself already. Then if you have specific questions you can ask around again.

Not trying to be difficult just dont have all that much time right now sorry, maybe others do smile.gif

That's the idea and it's mostly true. You can play with Override Voltages in the 1.26 - 1.29 range and see what you get. But like I said earlier, it's not normal to have to do anything for stock speeds.

Okay thanks both of you for all your feedback. I think he's going to swap the chip. I also wonder if he should return the Cryorig C7 for something beefier. We're just looking for good temperatures with no overclocking right now and I'm going to feel bad if even after the swap he has high temperatures.

No problem. smile.gif Good idea to look into stronger cooling too. I think the C7 is only slightly better then the Intel stock cooler, relative to everything else on the market. It might be enough if you get a chip with a stock VID of 1.2ish or under but then youre playing the lottery again. There's a very good reason Intel isn't shipping a stock cooler with the 7700K as you've found out.

I'd still be interested to know what the case fan setup is, I'm sure that most of your problem is a high stock Vcore on a small cooler, but good case airflow definitely helps all round whatever cooler youre using.

He has 2 case fans plus PSU fan. He has a photo of his case, but his phone bricked on him 2 days ago and he's still working on fixing it (when it rains it pours).

Theres some good tips in the guide I linked earlier in the thread, good case airflow really can make a big difference to temperatures, and just having fans doesnt equal good airflow.

Let us know what happens with your friends chip, hopefully he gets a better one this time. thumb.gif

If you use manual mode, yes, the cpu will run around the selected vcore at all times. Thing is it'll most likely be up and down due to overshoot under load and vdroop. This is where LLC comes in.

Ideally, you want to run adaptive voltage, meaning the vcore will drop sub 1v in idle and then ramp up to whatever it's set under load.

You should not need to up the vcore for stock clocks though, if anything, in most cases the cpu will run at stock even under 1.2v. 1.29v should be enough for 4.9ghz or thereabouts.
