CPU downclocking when launching game

Hi there, I have overclocked my 10900k to 5.3ghz fixed on all cores with hyperthreading disabled.

AVX on 0
Ring 5000mhz
Core Voltage 1.470V Override
LLC just under flat at slight decline at mode 3
C-state disabled
Shift technology disabled
EIST disabled


HWinfo temps never above 80c and generally below 70c during session
Core voltage in HWinfo does not change from 1.470 as the load changes


When I launch a game, PUBG, the clock speed drops from 5.3 to 5.1 then 4.9 over the course of about 30 seconds as the game is launching.

This does not happen at all under full load when stress testing, and the speed remains at 5.3 under these circumstances.

Someone please help me :( I just want my consistent speed. I tried it at 5.1 as well, and it appeared to work just fine at 5.1 without downclocking.
 
whats your complete setup?

I want to know what case, motherboard and power supply you use.

What are you using to monitor speeds?!

My bad perhaps it's power related?!

Hwinfo64 is usually pretty good, though running more than one at any time can mess with the figures.
Though to me it sounds like you're hitting a power limit personally, it could take a few bios tweaks to get past IF it's possible.
I haven't over clocked your chip before so I'm useless on further options.
But I would suggest just running hwinfo and the game and nothing else, no RGB software etc.
Hopefully someone else more helpful will chime in.
 
will give a kidney for someone to help me fix this.

I use HWinfo. Thats the problem though, the downclock occurs before I even hit the main menu of the game.

What settings do i tweak?
 
It sounds turbo-boostey type behaviour, have you tried disabling all that stuff too? I have no idea how they interact with eist/speedshift when these are disabled. The 10900 has turbo boost 3 and thermal velocity boost.
 
All core 5.1 not fast enough?.... :ohwell:

Probably is fair to say all core boosts of 5.3 in game would require quite the chip and custom extreme cooling too.

Here is a video demonstrating the issue, also, when the application is closed, the speed does not return to 5.3 until I restart the computer.

My cooling is fine, at 5.3ghz on all 10 cores with 1.47 i am always below 68c under gaming load and I idle at 29c-38c

Yeah but is that doing nothing, sustaining high core speeds while loaded is considerably harder, try running a cpu stability test, use prime95 or something lighter but none that is short , longer than 10 minutes.
I think your hitting the chips thermal/power limits which for some reason are not being bypassed by your bios settings.

Stress tests are stable, I will run another. It does thermal throttle as I have set a thermal limit of 93c and under heavy stress testing it does unfortunately get this high, so I never surpass 10 minute tests as its unnecessary. I dont plan on doing rendering or stress testing for fun, I am planning to use this for gaming only which my cpu never gets anywhere near the thermal limit when gaming.

It doesnt stay that hot, but occasionally spikes to that level then comes back down to the mid to high 70s / low 80s then slowly climbs back up again, then goes back down.

During gaming sessions that last up to 8 hours at a time, I have never seen it surpass 81c and rarely surpass 75c
 
Do you have C1E/SpeedStep active ?
Because it looks to me like dropping frequency to save power when usage isn't high enough.
Changing minimum cpu performance in power plan might help.

I get you but you have to appreciate No one can know what you have done so far, and some may lead you down the wrong path by accident, we are trying though, I took a look at your manual, not very helpful since it has no bios settings pages.
Probably going to need a msi board owner.

If it were me I would be hunting through the bios, and I might screangrab or photo the bios pages to show others the available settings to change.
 
Thanks for the responses guys, lets keep getting to the bottom of this.

I recorded another video of a 5 minute stress test, following the launch of the game again after successfully completing the test. 5.3 failed at 1.47V so i reduced to 5.2ghz as explained in the beginning of this video.


The point of the video is to demonstrate that under full stress load, the core clock speed does not change and remains static as desired, however when the game is launched, once again we downclock. This is to go against the comment about the heavy loads not being sustainable with higher speeds, which in this case, clearly is not the problem.

Under 100% load, we are fine, under 50% load with a game we downclock.

Feel free to fast forward from the start of the test to the end of the test as it takes about 5 minutes, but make sure to view when I launch the game as well towards the end.

Is this in response to my video? or unrelated? I will still disable it as per recommendation, just wondering as I want to get a response on the experiment I just conducted as well from whoever reads this
 
So what are you actually losing in PUBG when your CPU runs at 5.1 instead of 5.3?

this is a response to your downclocking problem.
TVB Clipping reduces the multiplier to stock values when you're above the VID and clock speed (even manually)

significantly better 1% lows, not higher framerate. 5.3 instead of 5.1 the 1% low improves by 20-30 frames

I would recommend checking out the video, however I will be right back and disable that.

Possibly because of the nature of the load, stress tests will often hammer either 1, or all-cores and nothing in-between, whereas other forms of load can spread across the cores/threads and that will use voltage/frequency tables.
