First try at 4.6 and 1.3v

This is my system pretty much at idle. btw my cpu cooler is a zalman reserator 3 max dual.




BTW this is what the load results look like when i run intel burn test.

You may be able to get much lower. My X batch can do 4.6 GHz @ 1.20v VID, 4.8 @ 1.26 VID (adaptive voltage mode).

IBT, and the version you are running in particular, will drive the temperatures sky high using the advanced floating point instructions. It is not a real world test and you can damage your CPU by doing it too often. Better tests are video encoding: X.264 and/or Asus Real Bench.

What kind of cooling do you have?

Adaptive voltage can ramp up crazy with some instruction sets. It's usually recommended to manually set vcore at 1.25v and see what the highest multiplier you can get and go from there. Glad you found your "smoking" gun. gunner.gif

The smoking gun was the 1.5V idle VID. That can't be stock Gigabyte and it can't be adaptive else the VID would have dropped down to a low value at idle.

Adaptive is fine - it does what it is supposed to. Cores running advanced floating point instructions require more voltage to keep stable and adaptive gives it to them like it should The problem with adaptive is running it with synthetic stress tests that run advanced floating point operations in tight loops, requiring lots of volts and power and generating lots of heat. You will never generate such loads. Tests that generatre such loads only serve to stress and test your cooling system (I never thought I'd say that).

That is a good suggestion about setting the voltage and see how high you can get on multiplier. Only thing I would suggest is to start at a lower voltage - say 1.2, mark the highest multiplier you are stable at, then up the voltage and repeat. Depends on what your goal is.

I have the gaming 7 and temps with an nh-d15 are in the high 60s to mid 70s
That is 4.7ghz, 1.32v

Your temps are very high for that moderate OC! 94c!!!! doh.gif

You need to do something with your cooling...

Are you still using the auto OC? Or, OC'ing manually?

Hi. Running what and what ambient temperature?

If you look at his first picture it shows ~0.9v and 33C at idle. I'm pretty sure thats using adaptive and stock settings which is why he called Gigabyte about it. I've seen this on a few of threads where someone fires up P95 or IBT with stock bios and get crazy volts and temps.

Edit: I see now what you're talking about with the VID...

My bad...i usually use x264.. Tried a bit of prime95 v26 but can't really recall temps from that one. Ambients are 26C in an air conditioned room. Cooler intake temps are usually about 3C higher

Yeah, with adaptive or offset the VID would have dropped too.
