Hello all,

I am a long time amd user. I recently jumped ship :(  I have been poring through guides and such, learning the intel system.

this is my new specs(will update my user config at some point.)

i5 3570k (oc 4.7ghz)
CM 212 evo (push pull)
asus sabertooth z77
Corsair vengeance 2x4 gb @ 1600 mhz (9-9-9-24-2t)
corsair tx 650w
evga 2gb gtx 670 ftw
ocz vertex 4 64gb
ocz vertex 4 128gb
seagate 500gb barracuda
seagate 3tb
windows 7 ultimate x64

Ok so i have a few questions.

I have the computer oc'd at 4.7 ghz. I did this using the "manual" method as described in this guide (which i just copied the settings, then adjusted the multiplier, and voltage to get me to 4.7ghz)

http://www.overclock.net/t/1291703/ivy-bridge-overclock...

I am a little confused, as to the offset method. the goal is to get my vid to match my vcore? so it helps reduce voltage use? currently, my cpu idles down to 1.5 ghz, but voltage stays at the 1.280. I read you take the vcore, and subtract it from the vid. this gives you your offset. my vcore is 1.280v, and my vid is 1.179v. which would make my offset 0.101?
now, do i just plug this into the offset setting? I am also reading about, changing the phase control, and the llc?

also, in windows system panel, it only shows 3.4ghz. is this normal for the cpu to run at the over clock but windows only see's its default?

I am getting a little frequency jump, 4699.83 mhz - 4700.23 mhz, is this normal? is it do to vdroop?

if anyone could break the offset down, into easy steps for this dullard, that would be appreciated!

Thanks for any help!

Windows always displays the factory settings of the CPU for me as well, running at 4.5GHz. Don't worry about that.

The little frequency jump is also normal. Mine usually reads 4499MHz at load.

As for the vcore, as I understand it, VID is the voltage required to run the CPU at stock settings. I offset my voltage by lowering the default value and increasing the turbo allowance. This idles it at a lower voltage and hops it up when necessary. After mild tweaking, I have it around 1.1 idle and 1.34 load. I plan on messing with it a bit more, and maybe trying a higher overclock.

Just curious, what are your temps looking like with a Prime95 test? I have the same cooler as you, as well as 9 case fans of various sizes. I leave all the fans on low settings and top out around 70-75C.

Hey,

Thanks for the info! I am gonna mess with this more this weekend. I just did 9 hours of prime95, temps were 83,90,88,84C.
4.7ghz, 1.296v. ambient room is about, 22c. I am idleing at about 33c.

Would really like the voltage to drop when idle. so again, thanks! will give this a go later.

Not bad at all. I am about to try shooting for 4.6. I think 4.7 is a little hot for my liking.

By the way, here are some benchmarks I did on my overclock, if you are interested:

EDIT:

Wondering how you could have possibly hit 4.7GHz stable with that voltage. I'm pushing over 1.4v and still just narrowing in on a stable OC @ 4.7...

yeah not sure! I ran prime95 for 9 hrs on 2 different occasions.

I did finally get the offset, working....i think!

i did raise the voltage a bit, i am at 1.296v at this point. my vid is 1.1709. i did a positive offset of .12. Im hitting my voltage that i wanted, but am still wondering. The vid hasn't changed? it stays the same. the vid, and the voltage drop, when it goes idle( which im assuming is what i wanted,) but it never goes up. I guess i was assuming(...again,) that the vid, as shown in coretemp, would match my voltage readout in cpu-z?

i will get some pics of settings, this weekend most likely.

Thanks again!
