I know that Vccin of 1.9V is safe, but my overclocks seem to require 2.0 or higher for stress testing 4.5 or 4.6 ghz. I wonder how good of idea is it to use 2.1...
See Darkwizzie's settings, i believe he is running 2.1V VRIN/VCCIN but pls double check.
What is your uncore multi and ram? OCed uncore can really destabilize so are you keeping it and ram at stock while you're trying to determine your max core multi/voltage? (again this is in the darkwizzie's guide tongue.gif)

That represents your actual VID of the chip. usually below 1V is a good OC'er clocker.

i still can't find it frown.gif( what name does it show up under for you?

For non-full load intel has some algo (i think you need to also have C states enabled possibly) but for boost it takes what you give it. The issue is full load for 1 core and full load for 2cores and full load for 3/4 cores will require different voltages. Adaptive only allows you to provide one.

EDIT: well it takes what you give it except for the special AVX (or whatever they are called) instructions where it actually takes your specified max + some offset, this is hardwired in the FIVR so it's not controllable, which is why you never stress under adaptive
Not according to my experience (perhaps it depends on the motherboard. I have ASUS Z87-A). When I set voltage to adaptive and "Per Core" overclock, the voltage was higher on 1 core load (4 core load had lower voltage). I didt'n write the parameters down, because I stopped with this overclocking method (the voltage span was too big to get a decent overclock).

Edit: I found a note that voltage changed automaticali from 1.264 (4 core load) to 1.424 (1 core load), but I don't remember at what BIOS setting.

But where do you find it or what software do you need?

At default settings, you should be able to see it in your BIOS/UEFI, or by using CPU-Z.... thumb.gif

Got a new 4770K to replace my old L314A batch.

Username: iatacs19
CPU Model: 4770K
Core Multiplier: 45x
CPU VID: 1.175v
Vcore: 1.175v
Input Voltage: 1.968v
Uncore Multiplier: 42x
Uncore Voltage: 1.084v
Cooling Solution: Noctua NH-U12s + AP-15 fan
Stability Test: AIDA64 3hrs, XTU 2hrs
Batch Number: L316B Malay
Ram Speed: 2 x 8GB 2400MHz 1.63v, IMC stock voltage 0.88v (MemTest86 2 passes)

This new L316B is a very nice sample. I can boot into Windows @ 4.7GHz with 1.200v no problem (per JJ's method of quickly testing for quality) and run Cinebench 11.5 and 15, but it throttles when stress testing with AIDA64 or XTU. I think with water cooling this chip can go even higher.

I noticed that if I clock the uncore/cache to 4.5GHz then it needs ~1.27v, but if I clock it at 4.2GHz it only needs 1.084v, quite a large power increase for 300MHz of cache speed.

I have tested 4.6GHz successfully with 1.205v, but I didn't feel comfortable running it without better cooling. Overall I am very happy with this new sample. I am going to test a bit more then switch it to adaptive voltage and call it a day.

I did get a 4-6C reduction in temperature during stress testing and 3-4C in idle by enabling some of the features in the CPU's FIVR. I used this guide:
http://rog.asus.com/253612013/labels/rog-exclusive/maximus-vi-power-saving-power-tuning-guide/

But, I only changed the following settings:
  • CPU Integrated VR Efficiency Management: Balanced
  • Power Decay Mode: Enabled
  • Idle Power-In Response: Fast
  • Idle Power-Out Response: Fast

The other settings are not necessarily CPU related and could cause some issues depending on your other components.

Thanks a lot for that, it was on my TODO list to look into those, good to be reminded! :-)

I made the mistake of having uncore at auto and it was overclocking and over volting on auto. I'll try again, thanks for pointing that out.
