Ivy Bridge overclock guide?

Anyone have a link to a quick overview of how to go about overclocking an IB processor? I understand that you basically change the multi and voltages and go, but I want a better explination of bclk and what all the new stuff is that I don't have on my P35 board.

Thanks.
 
Try reading my post first will you? All that thread talks about is voltages and stress testing. I know about that. I want to get more info on the settings most people don't touch as I mentioned bclk and how they factor into it all.
 
There is a reason people don't touch baseclock on SB/IB. It very quickly makes your system unstable, leave it at 100. What else would you like to know that isn't covered in other threads on this forum?
 
OP there are a bunch of settings in the BIOS but they don't do much of anything. You can adjust:

VCCSA
VCCIO
CPU PLL voltage

I have found that by reducing the CPU PLL voltage a touch I was able to run stable at a lower vcore with less heat, but the difference was very minute.

Basically you just set the CPU offset voltage, change the multiplier, and away you go.

Some people suggest things like disabling virtualization and some other stuff but I have found that it is not necessary.

Yes, I did read it. You could have asked your question in the other thread.
 
Ok...cause as you can see I haven't overclocked a system in about 5 years. Back then you had multiple voltages to adjust for stability, contend with memory voltage and timings at your selected FSB speed and have to balance it all.

I know the new Motherboards have a bunch of settings (i've built a few systems around them for people I know), but I have never messed with overclocking. Just stock stuff so far. I wanted to know what the different settings affected. If they don't matter then it makes it easy. Thanks
 
Basically, turn off C3/C6 after 4.5 GHz, don't touch bclk, adjust LLC accordingly, use offset instead of manual so you don't use too many volts at idle, and stress accordingly with IBT, Prime95 Blend test, etc.
 
No need to turn off C3/C6 unless you have a specific problem caused by it, this has been posted countless times now and is getting a little boring.
 
or you can check Sandy guide as well, I think other than a few small differences they are essentially same procedure when it comes to OC. heck they use the same board.

There are numerous thread within the first 3 pages on this forum that detail exactly how to overclock SB/IB cpus, reading any of them would have given you a pretty good idea that all those things you just mentioned are obsolete now. Anyway seems you got your answers, good luck.

Yep pretty much identical apart from IB having lower voltages.

Just because they aren't mentioned when someone just wants to clock to 4.5Ghz in 2 minutes doesn't mean I don't WANT to know what they're for or what they do or how they work etc.

Any monkey with a finger can press a couple keystrokes. I wanted better information about unmentioned BIOS options.

Thats the best part. You Don't NEED to fiddle with every voltage setting in the bios. Just make sure the Vcore is low and the VTT is 1.8v or lower.
 
OP there are extreme overclockers that try for 5ghz and tweak all those voltages in the BIOS. I doubt you will approach 5ghz with Ivy though; really you just need the vcore IMO.

I can hit 5Ghz with everything in the bios on auto and ust adjusting the Vcore. The days of fiddling with every voltage died with 1366
 
I'm not trying to hijack the thread but is the offset voltage the turbo mode voltage? Is there a way to make it so that it only overclocks during load? Again, not trying to hijack just want a quick answer. Thanks in advance! 😀

If you enable the C1 etc states and speedstep then your CPU will drop multiplier when not in use and ramp up when under load. I have tried this on my P35 board and it works fine. I used to have to turn it off because a game would go idle then load then idle on the CPU and cause some stuttering.

Yes it works that way by default if you use offset voltage.
