Overclocking with Adaptive Mode (8700K & Asus mobo)

[SneerRolts]

I have been attempting to understand "Adaptive Mode" for overclocking my 8700K on Asus z370-a motherboard (with the latest bios version). With the manual setting I have a stable overclock of 4.9GHz @ 1.32v, that bit was nice and easy. However the idea of the voltage going up and down as required rather than forever being at the higher value is a nice idea hence Adaptive mode attempts.

 

I get into windows and as everything is loading up the clock speed is as it should be (4900MHz) then when idling the voltage drops from 1.344v down to 0.640v which is exactly what I want. When I then go to load cinebench it works fine clocking back up the speed and voltage, however if I do a stress test Realbench/Prime95 26.6 it ups the speed and voltage for about 15 seconds then it drops the multiplier down to 44/45 and voltage to 1.2v.

 

Can anyone explain to me why this is happening and what I have done wrong?

It isn't thermal throttling as temperature doesn't go above 75C (and when on manual @ 1.32 didn't go above 78C after 3 hours).

 

My goal isn't to underclock my CPU so very puzzled right now as whatever I do doesn't seem to stop this happening.

Please help me and end my pain/confusion!

 

My settings in BIOS:

Adaptive voltage - 1.33v

Offset Voltage - Auto

SVID Behaviour - Best Case

SVID Support - Enabled

LLC - Level 6

IA AC/DC Load Lines - 0.01

CPU Core Ratio - Sync All Cores

Core Ratio Limit - 49

@SneerRolts

i have the same CPU and Motherboard and i couldn't get Adaptive voltage to work properly.. it's very confusing

but what i do is enable Speed Step and Speed shift, and my CPU downclocks itself on idle with Balanced Power Plan but the voltage stays the same, 1.32 isn't that high to be honest so you should be fine to stay on the same voltage.

Sounds like AVX offset doing its job. Try manually set it to 0.

[SneerRolts]

@syn2112 Well here is hoping we can both get it sorted, fingers crossed. Worst case I will have to resort to having it on manual with the cpu downclocking iyself when idle as that was running nice and smoothly yesterday but if can have the voltage adjust itself as well then will be living the dream.

 

@Jurrunio Good thought, just put it to 0 in BIOS and tested. Same issue occurs, the mystery continues.

i agree i also would like adaptive voltage to work

I assume it doesnt do this with manual voltage?

 

Does one or more of the 'workers' stop working due to errors?

[SneerRolts]

@Jurrunio No problems at all when using Manual voltage, it stays nice and consistent on the speed and voltage. Only happens with Adaptive.

None of the workers have errors/stop working. Regardless of the application I use to benchmark/stress after about 15 seconds the speed/voltage dip and stays at the lower level.

ran out of ideas. Maybe someday I could afford a new system with an Asus motherboard.

[SneerRolts]

@Jurrunio No worries, thanks for the help. I just upgraded from a 2500K myself, it was so worth it even with the hassle of the adaptive mode on this mobo.

[SneerRolts]

@syn2112 so after much tweaking and playing around I have sold the issue. Basically put it on adaptive, load into windows and stress test to see how much it vcore it wants to send to the CPU then reboot to get into BIOS and use the offset voltage it to get it to the level you want. You should know via testing in Manual mode to find out the stable OC voltage that works for your CPU. So if it was pushing 1.28v and you want 1.32v then you would want an offset voltageof 0.04.

 

My settings:

AVX Instruction core ratio negative offset: 3

SVID Behaviour - Best Case

CPU Core Ratio - Sync All Cores

Core Ratio Limit - 49

SVID Support - Enabled

BCLK Aware Adaptive Voltage - Disabled

Adaptive voltage - Auto

Offset Voltage - 0.035

.External Digi+ Power Control:

LLC - Level 5

.Internal CPU Power Management:

Long/Short Duration Package Power Limit: 255

IA AC/DC Load Lines - 0.01

.Advanced> CPU Power Management Control

CPU C-States - Enabled

 

If I havent mentioned changing any other ones then chances are its the default setting but do feel free to query away. Obviously I cant state that this will work for you or is the best and most official overclock as I've been tweaking away back and forth for ages... however for me it lets me have a consistent overclock at 4.9GHz without the CPU getting too warm and is stable. Plus when in windows and idle it lowers the speed/voltage like was the end goal.Tested in prime95 for 8 hours and all seems nice and stable with temperatures not exceeding 75C.

 

If you have any issues with stability, disable c-states or up the voltage slightly.

hey man LLC stand for Load-Lind calibration right? my option is regular to extreme dont have level 5

holy hell it is working beautifully, thanks alot man, i got the voltage where i want it and it drops to 0.63V on idle and 800 mhz

you're probably using a different board, Level 5 would probably be Medium i guess? experiment

[SneerRolts]

@Jun Wei Goh Asus Boards have LLC (Load-Line Calibration) with 1 as the weakest, 7 strongest. So on your motherboard go for just over half way, if you are getting too much droop then increase the LLC to compensate.
 

@syn2112 Haha indeed, same on mine. Works like a charm. Good thing you posted you had the same issue or I wouldn't have put the answer in this thread. Who knows someone else googling for a solution may come across it now as I know when I searched nobody seemed to have had the same issue.

Sorry for necromancing but i need your help. I'm trying to do exactly what you are doing.but am stuck at setting up the adaptive voltage.i have attached a picture. Can you help me determine where to put which value?
