cpu speed drops

[Mando772004]

since i reinstalled windows when i play doom i notice my cpu clock drop from 4.6-4.7ghz to 3ghz then goes back even though my temps are 70 on the cpu. btw this never happened on the last windows only happened on this windows. bios settings are still default and this only happens on doom. im using a ryzen 7 5800x cooled by a x63 kraken which i just got today and im using a b550 tomahawk (just installed latest bios). is this normal?

You mean the last build of windows? Last windows would be 8.1 which was a while ago.

no i meant the last copy of windows 10 i had before reinstalling

Ah.  Build then. Those can be rolled back I understand. New ones often develop new bugs as older ones are fixed.  If a roll back doesn’t fix it though it may be a different problem and the timing is merely coincidental.

it only happens on doom though. like running cinebench under full load my cpu reaches 85c at max and on all cores my clock is 4.5ghz i dont know about you but those are decent numbers for a 5800x if im not wrong

i noticed since i installed a new cooler and installed new windows and latest bios my cpu clocks drop to weird speeds like in this video, it drops from 4.7ghz to 3.7ghz which never happened before installing the new cooler and windows and bios. (ignore the sound in the video)

SPECS:

RTX 3080 latest driver

r7 5800x cooled by krakenx63

32gb ddr4 4x8 cl16 3200mhz memory

b550 tomahawk

GX850 PSU

H500p case

Windows 10 version 21H1 power plan set to ultimate performance

1440p gsync monitor

 

 

quick note: when i run cinebench my temp reaches 85c and the clock never drops below 4.5ghz on al cores which is weird cuz this is under full load

It clearly isnt doing full load in the game

Could be something in doom then. Doom is known to be more compatible with various stuff and run better on various hardware than a lot of other games.  I don’t know what it does different, but it’s got to be something.  Not impossible doom simply isn’t pushing the processor pal the way because it’s just that easy to run.   If one part of your machine is pushing max but another isn’t thats normal. The line can only move as fast as the slowest member.

Yes but it never dropped to such speeds before

It probably has before, you just can't see it. Ryzen adjusts its clocks every millisecond, no way to display that on a screen without turning into a blur and you need a 1000Hz monitor to have all numbers displayed (attempted to be displayed, there's grey to grey response time to consider) at least once. The CPU also doesnt run the same clocks on all cores at the same time, I suppose the OSD you're using only picks up data of one of the cores or the fastest core out of the 6.

im running msi afterburner and i never saw this happen but maybe you're right i guess. im sure im not thermal throttling cuz my temps dont exceed 73c

i know people told me cpu speed dropping from 4.7ghz to 3.7ghz or less in a second then going back is normal but it really wasnt happening before when i was monitoring using msi afterburner, i know that for a fact.

things i did since the last time the speed was stable and normal at 4.4-4.8ghz:

installed a new and better cooler Kraken X63

installed nzxt CAM

Installed a new copy of windows and yes my performance plan is set to ultimate performance

updated bios and set xmp on

 

Cpu is a Ryzen 7 5800x stock settings like i always i had it

Also quick note: my temperature is usually 65-70c

then your machine is normal , what's the issue youre having

i want the speed to be stable like it used to, no way in hell did it drop to such speeds before doing the things i listed above. im sure cuz i monitored my pc everyday

Just go into the bios and set an all core 4.5 or more, that will basically force your cpu to run at those speeds at all times

i would prefer for it to boost by itself like it did before

You can lock the clock speed in BIOS like a manual overclock, but you dont get the benefit of going higher under light loads and this shows as worse performance in tasks that really needed low thread count performance

 

or you could turn off C-states and other power saving stuff

its weird because this was never happening, and i dont want to do anything manually to make it run like it used to i just want it to clock up by itself like it used to

So you're just being paranoid to something that looks off but makes no impact on performance, right?
