i7 3770 (non-K) core voltage?

post #1 of 23
Thread Starter 
I've searched around a bit but I figured I'd get the most reliable information here. So I'm going away to medical school and I can't take the rig in my sig as much as I want to, but I was able to snag an Alienware X51 from the Dell Outlet on black Friday for a pretty amazing price. I put AS5 on a replacement stock CPU cooler they had to send me (first one was making a constant headache inducing high pitch noise) and ran Prime95 for a couple hours to test a little. My temps went to 80-82C max on all cores and they're idling now at about 52-58C. I suppose that's alright considering this computer is the size of an Xbox and taking into account the AS5 hasn't had time to fully settle in but if anyone knows anything about the X51 they can share, please do.

Right now CPU-Z is saying my 3770's core voltage is at 1.360V so I'm a little concerned because I haven't tweaked anything (everything is as it came). My i7 930 in my custom rig is at 1.325V on a 4ghz overclock (has been for 2.5 years) so I'm pretty confused. Would I be safe attempting to lower the voltage to say 1.25V?

I'll attach a pic of what I'm seeing idle right now. Thanks guys! X51 i7 3770.jpg 166k .jpg file

If you have the option to reduce the voltage, give it a try.

I'll take a look in the BIOS. I just wanted to get a little feedback before I go and fry my 3770. But is it normal for one to be running at 1.360V untweaked at stock settings?

Haha k, gonna see if I can do anything in the BIOS now. 1.360V just doesn't seem right.

Edit: Doesn't look like I can do anything in the BIOS frown.gif. Are there any software options or can anyone suggest anything?

I don't think so, if you're feeling lucky you could try delidding it for better temps, there's a tutorial somewhere in the forums.

It's nothing to be concerned about, really. This is the way the manufacturer designed the laptop. It'll endure. The voltage is controlled by the BIOS automatically, hence a voltage that seems to be "off".

Thanks for the encouragement but the X51 is a desktop lol. I think the post still applies to it though smile.gif.

if your bios is running it at that voltage in auto then thats what it will run it at but it really shouldnt be doing that high though. which makes me wonder if there is some goofy bios settings that you overlooked

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
