Overclocking a 3770k.

post #1 of 22
Thread Starter 
So, I've had my 3770k for a few months now and I decided I'd mess with my clock speeds a bit.
Right now I'm running it at 4.5GHz with a core voltage of 1.288v under full load.

CPU Voltage: 1.140
Offset: +0.020v

Is this decent? Good? Terrible? I honestly have no idea.

Is there anything else I can do to make this run more efficiently at 4.5GHz?

Thanks in advance.

I'm also getting between 59-61 degrees C while running AIDA stability test.

yea, that looks decent to me,
you could try lower it some more, see where it starts to crash, then up a notch or 2,

would be helpful for others if you fill in your sig,

All right. Thanks.

I've just been messing with ASUS suite trying to get the CPU voltage as low as possible.
Do you happen to know what the average CPU voltage might be? Well, for those who use ASUS suite. I'm at 1.120 right now and I don't know if I should go any lower. I'm keeping the offset at +0.020 for now also.

srry for the late response..lol was dinnertime over here ,

hard to say, but on average 4.5ghz and 1.230V,
i need 1.2350-1.240V vcore to make 4.5ghz run ,and mine is concidered to be average smile.gif
1.25V is good, under 1.2V vcore is very good for 4.5ghz

doesnt matter much if you use software to oc, or use the bios,
i prefer bios oc tho, like others around here, software can fail,
but it can be a good tool to use when you start ocing tho smile.gif

we do have a thread here with guide to oc on Asus mobo's,
you prolly already saw it but,

Wait. Are you using a fixed voltage (1.120) or an offset (+0.02)? When you run Prime95 or IBT, what does CPU-Z show for your Vcore? That's the number you need to be worried about - the load voltage, not the idle voltage.

It you are really stable at 4.5 at 1.288V (from the first post) that's pretty good. You might be able to get that down closer to 1.25, but 1.28 is fine for long-term use. A lot of chips lately seem to be taking closer to 1.3V for 4.5~4.6.

I use the exact same Vcore. 1.288 V for 4,5 Ghz. Its not really great but it could be more worse.
You can try to lower it. Maybe you can archieve 1,25 V or lower with a great chip. I prefer Prime95 for stresstesting but AIDA is fine too.

My fixed voltage is 1.110v with an offset of +0.020v right now. Under full load it maxes out at 1.256v running at around 55 degrees C max. I'm still going to keep going down until it's unstable but that's going to have to wait a while. Stress testing in between every other undervolt for an hour. Once I get to a comfortable voltage I'm going to run AIDA stability test over night.

But yeah, so far it's stable at 4.5GHz at 1.256v.

Yeah, I normally OC through bios. I just decided I might as well use software to OC since I don't have to keep rebooting. Seems more efficient to me. I can also monitor my voltage as I overclock further if I decide to.
