Absolute Core Clock Fluctuating

Nvidia Cards
1

I have 3070 ti zotac trinity oc edition, having strange behaviour. It is keep core clock fluctuating, while other GPUs are normal, strict on it overclock parameter. Any one have same experiences and solution? Thanks

2

Is it thermal throttling?

3

Temperature still less than 60 C, so I think it is not thermal throtling.

4

Can you paste the output of this command: nvidia-smi -q

Core clock set 1125 but actual fluctuating between 700 to 1125

8

Yep, it’s thermal throttling. Turn the fan to 100%

9

How much temperature target ideally?

10

Thermal throttling happens at 110c on the memory, so less than that. I run all my gddr6x cards at 100% fan, fans are the cheapest part imo.

11

isn’t it because of VRAM speed? 3500?.. GDDR6X is problematic… maybe if you change the thermal pads will sort it out

12

nvidia-smi -q | egrep “Thermal Slowdown”
is enough to write i think

13

So if thermal throttling normally happens at 110c, then why in my case, it is happens while still less than 60 C ?

14

because in hiveos it shows only core temp, not virtual memory temps…
put your gpu at 90% or even 100% FAN speed

15

core temp vs memory temp

16

Ok thanks all…
