i7 3770K Overclocking on Sabertooth Z77 With H100

[TheCMStormStryker]

I have had my rig "Snow Storm" overclocked for awhile, at 4.7GHz (Using the Turbo Ratio and auto voltages) and wanted to see if I could get any more out of it. I tried 4.8 and it works fine, but I noticed it is pushing 1.49V through it! You can probably predict my reaction whenever I saw that... Lol. Any advice on what I should do? This is my first try overclocking. Also, with the 4.7GHz while running prime I would tap 70C occasionally and then the temps would stay between 64C and 68C. I rarely use my system at full load so if i wasn't running Prime95 then I never had it get close to 70C. What should I do?


Thanks, TheCMStormStryker

70*C at 4.7GHz is very impressive. Read Master&Puppet's Ivy Bridge Overclocking guide: http://forum.overclock3d.net/showthread.php?t=45604

It's done on a different motherboard, but the principles can be applied to your board also.

It looks as if you have a mighty fine 3770k.
If you barely use it at 100%,even 50% i would try 1.175v and go for a 45x multi.Maybe it wont boot,but some small adjustments to vcore or lovering multi to 44x could be wprime stable.Either you have to do some tweaking.
I would suggest you read Master&Puppets Ivy Bridge OC experience,its very thorough and explains Oc`ing very well.
He also made a thread called LLC and Vcore,its very informative too.
Suggest you read it and do some experiences yourself.
Unless you do some benchmarking i wouldnt go past 1.25v on vcore.

How does 4.7 GHz at 1.35V sound? Voltage too high?

 

[Josh Weston]

Yeah, i'd say so.

These are current settings.



Note the voltage on this pic...


Do you see anything wrong besides the voltage? I'm gonna work on it sometime Monday or Tuesday...

I wouldn't bother touching the BCLK on the CPU, change the multiplier only! Ivy and Sandybridge don't like to have their BCLK changed it's more hassle than it's worth.

Also there should be a memory setting for 1866Mhz, put it at that or whatever is closest to that setting.

Finally i don't know what the stock voltages are for the PLL/PCH ect is, but when overclocking i never ever leave any voltage settings on auto, that can cause some problems with stability and also with heat!

I'd suggest that you lower the CPUPLL and VCCSA a little bit to help temps even more. Work your way down the volts from where they are now and at a guess on your screenshots I think you'd be looking at about 1.6 for the PLL and 0.8 for the VCCSA but of course it varies - go as low as you can.

I'd also suggest that you turn off any vdroop control which you've got set. This means that you will set a higher vcore on the face of it but you'll actually be better off in real terms with lower load volts and temps. Have a look at the LLC thread (linked in my sig) if you want to know a little more about that.

I'd also set the bclk to 100 until you've got it all sorted. You'll quickly make the whole system unstable when you get towards 105. Play with it last if you want to.

4.6GHz+ is where things start getting a bit high for everyday voltage use. If you get it working in offset mode then that's much less of a problem depending on how hard you use your pc. You have to draw your own conclusion between fighting for the extra 100 or 200Mhz and the cost that has on the lifespan of the chip. For gaming anything in the 4.0-4.5GHz is typically enough, or more than enough, so most people would suggest a slightly lower clock.
