@cxmachi

AVX will draw more power at those clocks.
Best thing to do is set a AVX offset of 2, which gives you the default 4.5Ghz when running AVX loads.

Realistically 4.8Ghz vs 4.5Ghz in real world AVX loads (encoding etc) is not noticeable other than higher temps and voltages.

Interesting, so it will draw more power and ignore my adaptive voltage settings in the BIOS?

It will go off the cpus VID and draw more power, this only happens with adaptive voltages.
If you set a manual voltage it won't.

I've been troubleshooting with @cxmachi on Reddit and honestly I don't see the same issue he does. I too have a Maximus IX Hero and 7700k. I even took some vcore measurements while playing BF4 (unfortunately I don't have BF1 like him) and comparing against both Prime 95 and Realbench.

FWIW I don't run any AVX offset either so I'm kinda confused.

The screenshot below shows the first 90% with me playing BF4. I then close it and open Prime 95 and start benching (note the gap where my CPU Vcore drops down below the Adaptive 1.35V I've set). Same vcore readout. While I realize these are software measurements he's indicating a bigger difference that should definitely be detectable by software measurements. Could it just be different hardware behaving differently?? VRM differences?



Edit: On another note it looks like my max CPU temps bumped up a bit more since my last 8 hour Prime 95 run. I wonder if some of my CLU is pumping out from my delid or somehow flowing weird frown.gif

What can I say, it was the same with my 5820k, 6900k and now the 7700k.
Using adaptive voltage running any heavy AVX load will put the voltages over the set in BIOS unless you us manual.

Adaptive won't go any lower than what is set by the cpu's VID, which can vary from CPU to CPU, don't worry I was confused at first too, the guys explained it to me over on the x99 threads.

Here's my CPU VID, even though I have adaptive set as 1.25v, this was under a realbench load, which does use AVX.

And I'm telling you I'm using Adaptive voltage with my max set at 1.35V. My benchmark was Prime 95 28.10, so definitely there's heavy AVX loads going on.

Here's a screenshot of my Vcore (1.344) versus VID (1.359). I suppose one could argue it's "close enough" within the 0.016 resolution that we have? However if I look in my notes I have recorded load Vcore from 1.312 all the way up to 1.344 as I tried to obtain stability at 4.9 GHz. So the fact that my load Vcore in Prime 95 can go that low suggests my chip was able to go below VID (assuming it's been 1.359 all the time) at turbo.



Perhaps @cxmachi perhaps you can measure your VID and Vcore both under load in BF1 and Realbench.

On another note I got a BSOD today doing nothing. D1 error says Windows Reliability tool. Does that suggest more vcore? I did pass 8 hours of Prime 95 though. Perhaps I should look at RAM? Dunno.

From what I understand if it happens at idle it means the idle voltages are too low.
You idle voltages are much lower than mine from what I see in your screenshots.
Mine - 0.774v vs Yours - 0.675v

What was your LLC setting?

Just updating BF1 so I can measure your VID and Vcore there.

if that's the load vcore it's a great chip. thumb.gif
try 50/45 cinebench r15.

The 4.2/4.5 I mentioned was what the board runs after a clear CMOS state, I don't recall if that sets the Asus or Intel multicore. I really didn't spend much time in the bios, ran thru Raja's guide - I don't think he even touched on multicore enhancement - got it stable at 4.8, didn't touch cache clock, 3200 on the ram and then tore it down to delid.
