I am still asking why you would want to use adaptive over offset or manual? People do realize that adaptive vcore was introduced with the integrated VR on Haswell, and that it probably doesn't work the same was on Skylake, if anything I would think it's a relic Intel left in not to confuse BIOS engineers (there are even internal AC and DC LLC slopes left in the UEFI and they will f things up if you change them).

It might be your Voltage Regulator that is sending a signal to your CPU. Disabling BD PROCHOT blocks these signals getting to your CPU so the CPU can run at full speed instead of 800 MHz.

The Voltage Regulator is either too hot or power consumption is too high when stress testing. Preventing the CPU from throttling might cause the voltage regulator to fail. Your board is either defective or it is not fit for the kind of overclocking you are trying to do. You can try pointing an external fan towards your motherboard to see if keeping it cool helps. Make sure that any heatsinks on your motherboard are snug. It might be a case of poor design so you will have to replace your board with something else. You can try the exact same board but it might have the exact same problem.

The Turn On / Turn Off feature in ThrottleStop only controls Clock Modulation and Set Multiplier. It was a safety feature during the early days that should probably be ditched but some users still like it. Makes them feel safer I guess. Once you disable BD PROCHOT, this setting is saved to the processor. After that you can exit ThrottleStop and BD PROCHOT will continue to be disabled until you reboot. You might have to disable BD PROCHOT again after you resume from stand by.

I move to xpower after read your review on tweaktown... rather than hero...

Actually I never use addaptive of offset... but some people use that.. if not why they put that kind off setting on bios. ..

Like offset... give more voltage when cpu need... right?

Since I oc my amd 9370 to 5ghz... I always using manual override... more stable...

This is my first time using intel after 15years and jump to skylake, And I think all skylake mobo should copy paste from oc/high ends 990fx mobo bios lol... so no addaptive, offset okay. .. and always have spread spectrum disable....

I thought adaptive would be better because you wouldn't be pushing constant voltage through it all the time...when it is on Auto it varies the voltage so that at idle you see much lower voltages...and probably longer CPU life.

However, I just tried running Prime95 v28.7, build 1, in Blend mode and everything seemed stable for a few minutes:
  • Temperatures around 55°C
  • CPU Package Power around 70 W
  • IA Cores Power around 57 W

Then, everything jumped up and the PC shut down within a few seconds. I had HWiNFO loggin on, so I checked the data and this is what they jumped up to:
  • CPU temperatures jumped to 65°C
  • CPU Package Power around 85 W
  • IA Cores Power around 73 W

I also found in the logs that "RING: VR Thermal Alert" was initially at No, then started going up to Yes sometimes and eventually just stayed at Yes.


So I'm still not out of the woods it seems...

Anyone have ideas?

Prime blend uses different fft's. After 3 minutes it switches from a large fft to a small one, which drastically increases power consumption and temperatures.

I don't know what the RING: VR Thermal Alert is, exactly. In your case it might be wise to avoid small FFT/linpack but your mobo and CPU should be capable of running them!

"Ring" is the Cpu Chace, it have a different multiplier, it should be less then the CPU multiplier, maybe it id set too high ?
post #3447 of 11360
Hey guys,
I have a couple of questions, I hope you can help me with.

I have a 6600K on a Gigabyte Z170 HD3P currently running at 4.6 with a 1.325 VCore set in the BIOS.

At first I had LLC set to auto and it showed me 1.278V in HWInfo while doing the X264 benchmark.
Then I set the LLC to High and the VCore is now at 1.332V in HWInfo, are those settings correct? (Why was it running stable at 1.278V before? I find that very odd.)
I haven't gone to the max my cooling allows yet, but I'm pretty happy with what I got so far. I think I can maybe reach 4.8 or so. We'll see.

One thing I haven't figured out yet is why my VCore doesn't go down in idle. I couldn't find the appropriate setting in my BIOS for that.

And the other thing is I have a Temperature reading in HWInfo, I don't quite understand. See the screenshot below. It just says "Temperature 4" and it reaches 93°C. Does anybody know what that might be?

Or is there maybe a guide to all the different Gigabyte BIOS settings anybody might know about?

Thanks a lot!
Cheers!

Are you running dGPU or iGPU? When I run the iGPU at stock it kicks off an alert for "RING: Max VR Voltage, ICCmaxx, PL4", not the same as yours but it's RING VR alert. If you're running iGPU I'm now thinking this is playing up somehow..

If you had 4.6 on 1.278 volt stable than you have a relay nice chip. For me 4,6 needs at leas 1,36 v

For Vcore , you have to watch the different displays, 1 number you set, 1 that in reality is supplied to your chip (HWinfo) and this is what LLC modifies under load.

Low LLc will let a vcore drop happen ( under load vcore lowered), with high LLC vcore drop dose not happen instead Vcore goes up ( making the OC stable but making it hotter)

As fas as my opinion it is best to find the middle ground , get a moderate vcore and get a moderate LLC, other option is lower volt higher LLC (but this will have bit volt pikes) Hi volt low LLC may not be stable or will run your cpu on higher volt even on idle, I don't like this option.

If you want your vcore to drop while idle you will needto turn the C states on, but it is not recommended for over clocking, it will make your system more unstable. If you have a reasonable vcore ,like 1,3x, you don't need to worry.

For temp 4 I don't think it is real, I have temp 1 2 3 4 displayed but they never change, no matter what I do, but I can be wrong on this.

Many times adaptive is set by default, but I have seen it messed up recently. The XPower is a solid motherboard, thanks for reading smile.gif

Yea that is what it offers, I am just trying to figure out why they kept it and how they implemented it, as this platform doesn't have a strong iVR (or maybe it does considering all the iVR settings) which can easily program to interpolate the voltage. I will investigate it more, as most brands use it by default, but i keep hearing new BIOS updates are screwing it up and fixing it, and I think that would point towards Intel keeping around a relic setting but with problems b/c its implementation is very complicated.
