CPU underclocks itself when running PUBG

[Tetsu412312]

So today my new CPU (i7 7700k) came and i installed it into my rig. I had a i3 6300 before. I tested several games like BF1 and assassins creed origins with these games my CPU ran at around 90% and i had very good FPS but then i started PUBG and it underclocked itself to around 2.0 ghz everything i tried didnt work I even forced my CPU to run at 4.2ghz in the bios but PUBG just dont give a shit and even at as i forced my CPU it got underclocked by PUBG. 

Any help?

 

My System:

GTX 1080

I7-7700k

8gb DDR4 Ram

 

BF1(Ultra Settings around 80-100Fps) ~ 4.2ghz

Pubg (High Settings around 20-40Fps) ~2.0ghz

can you download realtemp and show us your CPU temperatures? https://www.techpowerup.com/download/techpowerup-real-temp/

I have this program already temps are stable at 50degrees C

can you leave it open, do a pubg match and see your maximum temps? (This can pretty much only be explained by thermal throttling)

Still 50degress as i said i tried pretty much everything no thermal throttling

what motherboard are you using?

gigabyte z170 hd3p

maybe try running Aida64, it will put a lot of stress on your system and you can see if it throttles because of it.

have you tried intel XTU? it shows you a graph of the temps and clock speed, maybe we can see something there

Well, as much as I hate saying this. Reinstall windows

I’m building a pc right now and bought and i7770 k because they had a killer Black Friday deal. But I’m saving up now for the rest of my parts. I’d like to know why this happened so I might know for the future

I see your RAM usage is extremely high (percentage-wise) and disk activity is as well... are you running out of memory and swapping?  If that's the case, it would explain the low clockspeed and framerates - the disk speed is bottlenecking you so the CPU doesn't really have anything to do, and so it idles down.  If I'm right, more RAM would solve the problem but idk that just yet.

Yeah I agree with @Ryan_Vickers. It looks like you're hitting swap. Either try not running memory intensive stuff in the background (like Chrome) or pop another 8GB stick in there.

 

It's probably not doing that in AC because you're not hitting swap yet.

with my i3 it ran better also with this ram hitting top and even worse in disk space

lol PUBG took poor cpu optimization to another level.

Okay, maybe you had less stuff going on in the background then when you had the i3? it looks like you have a lot of programs open in the background. Try running PUBG with nothing else open.

no i have around 300gb and i also have an 60gb ssd with around 10gb free

Still nothing changed i just used my i3 yesterday with all these programs and stuff but the i3 ran with 3.8ghz and not like my i7 with 2ghz....

That is not related to my question... I'm curious about memory usage.  Check the "committed" amount, it might be more than the amount of RAM you have, and if so, that's probably the cause.

Commited amount is 6gb
