Auto will use the VID, probably not what you want. The VID at a given frequency is different for every processor. An offset voltage will adust the VID either + or - depending on how you've set it, and a manual voltage will use that voltage as a max.

At 4.3ghz my VID can get up to 1.306, but the voltage I give it doesn't get above 1.264. My VID at 5ghz is something around 1.6, but my processor only needs 1.48.

Auto at 4.75 is likely flat out bad advice, you're probably close to .2v higher than needed.

Seriously guys, read the guides, read the thread, every question I've seen asked in the past couple pages has been answered several times in the thread. Half of overclocking is reading.

This.

Offset OC still requires tweaking/stability testing. Auto could be using alot more voltage than you need, or not enough. There are never shortcuts to doing it right.

Can somebody please please please link me to a some sort of guide or tell me how to OC my i7 3820 to something between 4.00 - 4.50 GHz. I seriously cba to read more generic guides which get me nowhere and explain every acronym and what it does ect... I just want that thing OC'd hmmsmiley02.gif

This may help:

May not be for 3820 specifically but it will help you understand all of the options in the UEFI.

Up the multiplier to 43X. It should be fine on stock voltage. 4.3Ghz is that easy most of the time. To go higher than that will require a bit of tweaking.

Don't do this. Read the following below. 4.3ghz can be achieved under 1.25v. Personally I run 1.23v.

1.23 is what I need as well if I'm setting manual, but my offset can get as high as 1.26 on a swing. Average is probably around 1.008-1.088 surfing the web (no LLC).

I didn't tell him to touch the voltage. I upped mine to 43x and it was running at 1.24v, which is stock voltage. I guess it depends on the motherboard but my ASRock did not overvolt it.

Hey guys, my 3820 build is underway. I was wondering how big of a difference there will be water vs H100? Can you get a stable 5 ghz on water?

5GHz is hard for any 3820 to achieve using safe voltages. I would say it would make a difference between 4.5 and 4.875.
