hi. i upgraded my lenovo legion 5 pro ach6h with 64 gb kingston ddr4 sodimm 3200 mhz and I placed also new extra ssd kingston renegade pcie nvme m.2 1TB ssd . Everything seems to be fine. But after i turn on for example halo infinite, my gpu (rtx 3070) usage is suspiciously high. Do you think it’s normal usage or it is too high? I post images before replacement and after replacement.
My drivers are actual. My temps are high because i still wait for my new ptm 7950 to be delivered. Thanks for response.

Usage? No, CPUs and GPUs try to run as fast as possible intil they hit a limit

#

You should expect GPU to be used at 99% in most game

#

well yea but it is rtx 3070. i expected it to be used less when i do not run maxed graphics. thats why i am asking. so you say it is normal?

#

i have that laptop for 2 years but previously i didn't pay attention on that

#

Reducing quality settings does make it easier to make frames

#

But that just means that gpu will push more of them

#

Unless the process is fast enough that CPUs side is now a bottleneck in the process

okay. thats new thing i learned. but the bottleneck you speak about shouldn't be big because that cpu and gpu should be optimised from factory to work together i guess

bright ermine
#

Something like Space Marine 2 is very CPU heavy

#

So it's common for people to see GPU utilisation drop in that game

#

Like even the PS5 can drop to 40 fps there at 1080p because gpu just has to wait for the cpu to do it's part first

limber moth
#

ah okay. i can imagine. but for example lets say that halo has a lot of graphics to render, but i don't know how much that game put load on cpu. but apparently also more because sometimes my temps go up to 100 degrees

#

but i need to change my paste because i recently put there noctua instead of ptm 7950

#

it could be thermal throttling too

bright ermine
#

It is thermal throttling

limber moth
#

yea

#

but changing paste is my last chance to put things to way it should be, i hope it will solve my problems with heat

#

but why noctua still didn't reduce temps at least a bit down?

#

when its used in desktop pcs

#

i mean the heat transfer principle should work similar, right?

#

when its also heat transfer medium

#

and laptop is still thermal throttling

bright ermine
#

you don't have a heatspreader on a laptop for example

#

You are also more seceptable to thermal paste pump-out because of the smaller area

limber moth
#

and how is it possible that on desktop pc it won't pump out?

bright ermine
#

It will, but since you have a larger area due to a heatspreader, it matters less

#

While on a laptop you are applytingn paste directly on the die

#

So, any spot not completely covered by paste is screwed

limber moth
#

by die you mean what? i placed thermal paste directly on cpu and gpu on motherboard

#

as i saw on video

ah, so we mean the same
