i7 3770 (non-K) core voltage? - Page 2

if you want the voltage to go down because you are concerned its too high then you have to manually adjust all those settings lol.
i will say that voltage is crazy high for a 3770 non-k
i just upgraded from my non-k 3770. i clocked it to 4GHz and was only running at like 1.10V at the highest i remember. dont remember what i got it down to sorry
im currently running my 3770K at 4.6GHz at 1.288V for reference. but yea as you already know that higher voltage will give you higher temps. try resetting your bios settings. and seeing what happens. looking at your screen shot that is crazy weird if your BIOS is in auto and your are idling using 1.36V.
i would also be freaking out too. but try to play with bios some more hopefully you figure it out. thumb.gif

Thanks for the concern and info! I just went into the BIOS again and there really doesn't seem to be any options in terms of voltage or overclocking frown.gif. There was an option to hit F9 to load default values so I did that just in case but it made no difference.

Also, upon coming out of sleep mode today, I watched the voltage go all the way up to 1.392!! It went back and forth between 1.38 and 1.39 for less than a minute, then alternated between 1.37-1.38, before returning to 1.36. Right now I'm looking at it going back and forth between 1.360 and 1.368.

In terms of temps, the room I'm in is definitely cold. I need to wear a hoodie and jeans to be comfortable. The minimum temps in this new picture are from right when I came out of sleep mode (also notice the CPU voltage). The temperatures seem to slowly climb until they are a bit under 60C. The cpu fan is working fine but I know that the temps could be significantly lower if another fan was sucking/blowing air out of the system.

Edit: The max temps you see are from last night when I ran Prime95 for a few minutes to make sure the fan was working well. Also, the core second from the left always seems to run at least a few degrees higher than the others so I hope that's ok too.

There's still nothing to worry about. Temps and voltages are fine for being BIOS controlled. My reply can replace laptop with desktop and mean the same thing.

I spoke with a Dell tech support representative and they seemed to think that this was acceptable. I haven't had any crashes or anything but the voltages I'm seeing seem outrageous. I might try giving Intel a call to see what they think.

You're not going to overheat at 75C, you've got muc headroom until it's a bad problem.

EDIT: Ark Intel said TCase is like 67C... well, i'm not sure if you're in a good spot with this at the moment

Well I think my temps are going to be higher no matter what because the case is so small (about the size of the original Xbox360). In 2 hours of Prime95 the highest the temps got were 80-82 across all cores so I'm not too worried about that. The voltage is my only real worry since I've never seen it drop below 1.360V.

Yeah i always thought the Ivy chips could cope with higher temperatures. Have you considered delidding?

1.36 is enough for 5ghz for some 3770k's. You should be able to run close to 1.2v at stock.

I had never heard of delidding until starting this thread but somehow I guessed correctly as to what it was. I'm way too scared to try it haha.

Yeah when I first started CPU-Z I was expecting to see like 1.2 at max. Sadly this is how it comes stock and the Alienware BIOS don't allow any CPU tweaking besides turning on/off turbo and stuff frown.gif. I wish someone would make some sort of custom BIOS hack to allow full control.

Do NOT try delidding on a work machine.

 

What you should do is get a different TIM. You can get a top-rated Gelid GC-Extreme here, free shipping. They are OOS ATM, but I always get my GC-X there. whatever you get, make sure the TIM is easy to work with, and that you are getting good contact between the heatsink and the IHS.

 

Your Voltages may not be accurate -- mb's report what they calculate. This being Dell, I doubt you have spots to measure the real Volts. Also, higher temps greater resistance, which calls for higher Voltages. Get a good, easy-to-work-with TIM. AS5 was good in its day, but it is costing, resting on its laurels. It is too stiff, not worth the effort when there are a number of excellent TIM's out there.

Good to know about the voltage smile.gif. I actually had leftover AS5 so I put it on with the new heatsink they had to send me and my temps have actually been decent for such a tiny case (need it to be small for traveling/moving) with what I would call poor air flow.
