4770k OC Manual Voltage on Gigabyte UD3H

[rdjg22]

I've got my 4770k stable at 4.2Ghz with VCore set manually to 1.180V. I have no option for Adaptive voltage, only offset, but it seems that my VCore & Clock speed lower on idle. My only concern is the VID which stays steady at 1.180V regardless. Should I leave it set as manual or is there another way to set it up?

I run the exact same board and that is how I have mine set up and it works great. The only thing you lose is that you are slightly less energy efficient due to fixed voltage. Leave it in manual and be happy. If you don't like seeing the clock speed dropping on idle go into your advanced power settings and set your minimum processor state to 100%.

What do you have for cooling? Have you tried 4.3 or 4.4 yet?

Don't mind the clock speed dropping on idle, in fact its preferred...just wondering why the VID is a constant 1.180V but the VCore drops on idle to as low as 0.744.

I'm cooling with a Xigmatek Dark Knight II in push/pull (Corsair Air 540 case)...I've had it up to 4.4Ghz at around 1.25V but feel better with 4.2 and keeping it under 1.2V on air.

The system seems to be working as intended. When the CPU speed drops it doesn't need very much voltage so the voltage drops also. When the clock speed ramps back up so does the voltage. Is the system stable? If so, everything seems good to go. My overclocked i7 on a Gigabyte board does the same thing when I use the normal voltage setting with an offset. The CPU drops to around .75V on idle and goes up under load.

Very nice, I was just curious how your 4770K was comparing to mine 4.3ghz @1.176v under a Noctua NH-D14. I tried 4.4 but I was hitting mid 80's at 1.2 volts under stress test and still getting crashes so i backed it off.

They sound very similar.

Yes, the VCore drops on idle but the VID stays steady on the voltage I set, when under auto it goes up and down with the VCore...would setting an offset fix that?

Sounds like your chip is just a hair better than mine...I booted at 1.18V 4.3ghz and stress tested for 40 minutes before it crashed

The VID is supposed to stay constant. When using the normal voltage setting in the motherboard, the motherboard will assign a VID for your given max CPU speed. Your offset then adjusts the VID set by the motherboard. The VID is essentially just the BIOS voltage setting +/- your offset. The VCore will go from .75V or so at idle up to around the VID under load.

Ok, what should I set the offset to? Say...-0.300?

 

[Bonecrushrr]

Don't leave it at 0.00. The only reason to offset your voltage is if the voltage controller is consistently not putting out the voltage its supposed to be and at this point I don't believe there is any reason to suspect that.

Ok, sounds good. I tested on Prime95 @4.2Ghz with 1.18V and for the first 15 minutes it was 70 max, and then after 15minutes temps shot up to low 90's and I stopped the test, is that normal or should I maybe reapply thermal paste?

 

[shortstuff_mt]

Those chips run pretty hot. Different Prime95 tests put different loads on the CPU. I've seen considerable temp differences depending on which workload Prime95 has the chip under at the time.

Are you using large or small fft's? I get 65 to 70 degrees running large fft's and 85 running small.... needless to say I don't stress test with small much. so yes, it happens.

Just the blend test. Small fft's would push it to 85-90+ easily, which is probably what started after the first pass on blend

 

[Bonecrushrr]

That could be.

 

[rdjg22]

That could be.

Instead of starting a new thread figured I'd ask...I just ran Aida with everything stock and the voltage went up to 1.260, is that normal? Seems pretty high. When I say stock I mean stock in the bios, not through Easy Tune.

 

[Bonecrushrr]

With everything stock, IE voltages in auto yes that is normal. Under load your voltage gets turned up and the controller is generally far too aggressive. 1.26 seems a bit higher than normal at stock but as long as your not overheating you should be fine.
