Is it a bad idea to let the Mobo do the auto OC?

I have the Z77 Asrock Fatality pro....i just set auto oc 4.4. Should i be doing this manually?

Generally yes, sometimes no.

Depends on the mobo tbh. Mine is fine up to 4.4, at 4.6 it will start to give the chip too much voltage.

Manual is more fun anyways :thumbsup:

Depends on the board. Do you trust your board to be smart enough not to burn itself and the CPU when given automatic voltages?

I say it isn't worth the risk, since OC is not covered by warranty anyway. Just do manual and don't exceed 1.35V, you should be fine.

I've also found that the auto setting gives way too much voltage.

So it would be better to run at a constant 1.2v than having it peak at say 1.3 when it demands it and idle at stock volts?

See, this is what I was wondering. The auto tune function adjusts the voltage on the fly so it lowers it when there's no demand for the extra voltage. Is there a way to do that without auto tune?

Not really. The chip is made to throttle speed and voltages by design. Wont hurt it at all.

You should be able to control voltages by using offset voltage mode.

You should be able to control voltages by using offset voltage mode.

Even with offset, that still leaves it at a constant voltage, right? Like in the Newegg video, the guy says what's the point of having the voltage at 1.22 if the CPU doesn't need that at idle?

When you use offset voltage your board would still be able to drop both the speed and voltage at idle....Unless you disabled these features.

Depending on how the board is setup you'd just change vcore voltage from auto or fixed to offset mode. Then you'd have to play around with the offset to make sure it's stable at your desired overclock. Some boards just offset the base vcore, some just the turbo, while others allow both. Some boards also allow a - voltage offset which helps sometimes at lower overclocks.

OP, hitting 4.4ghz is so simple that you might as well do it manually. Give the CPU a tiny bit more offset voltage, set your max turbo multiplier to 44, and reboot. Then lower the offset voltage until you're perfectly stable as low as it will go. Monitor your temps and that's it.

In fact, you can probably do 4.4 at stock voltage. So just try changing the one setting - get your multiplier up to 44. Maybe start at 40 and work your way up.

Ill try that now. Thanks.

I have another question...what exactly is considered "stable"? Booting up and running Chrome? Or should I load up a 3D program and see how that runs? Or should I just do a quick Cinebench test?

The auto-OC generally works best when the software is in it's 2nd/3rd generation and the engineers had time to figure all the quirks of the CPU. IB being totally new, I imagine the software isn't that performant/reliable yet.

No major prob with auto except that you can usually oc similiar/higher with lower volts. So that is recommended, besides it is pretty easy anyway.

Auto over clocking is for Wussies.

Seriously, how could an auto OC possibly take into account all the possibilities of CPU, memory, and/or video card that may be in use?

It's okay, but you get more of a 'dirty overclock'.
It doesn't take long to push up a multiplier or a Base-Clock. I honestly don't know why people would bother doing auto-OCs.

My auto clock gets me 4.45ghz and I might be able to go 4.5-4.6+ manually but I like keeps volts and temps low. I have kept 4.3 at 1.27

I have the Z68 Fatal1ty and have tried the auto overclock with my 2600K CPU. It works fine up to the 4.4 setting, but at 4.6 and 4.8 I find it not to be stable. I run Intel Burn Test with 100 run and set to Custom 12000 MB (so most of the RAM is tested too). If that passes, then I know it's a stable overclock. Right now I'm using a manual OC of 46 multiplier with a voltage offset of +0.040 and an Load Line Calibration of 3. This has been stable with Intel Burn Test and Prime 95.
