GPU running at lower speeds

Post by sbohdan »

I have a weird problem , I have never encountered. My AMD RX 5700 XT IS running lower than the default clocks and it never boosts up to it's supposed boost clocks. The default GPU clock should be 1755mhz and the boost clock should be 1905 but in furmark it only runs 1650-1672mhz. The temps are fine, just 56C max. since I have a water cooling loop. GPU load fluctuates between 97-98%.
I bought the card used and the previous owner told me it was WC-d also and was running fine at 2100mhz, super stable.
If I OC it to 2100mhz, it actually runs about 1750mhz...

Any Ideas what could be wrong?

it may well be power limit and could be a driver that has made this happen.

Thanks for the link. I've read through but it seems they have no clue what the issue is. The problem is not minor though because 1650mhz is way off the 1905mhz stock boost clocks and even worst of 2100mhz that this card is capable with my water cooling loop. I've been googling this but nothing I so far...

Can you explain this? Why would there be a power limit by the drivers?
BTW, I did a complete driver wipe in safe mode and installed the newest drivers. Did not make any difference.

i cant remember off my head what the power limit in watts are for the 5700xt. it varies from aib to aib. but i have seen a few games that hit my power limit 200 watts and due to that can only hit 1800mhz although rare. a driver can cause the gpu to register a false power use and cause throttling again its rare but has happened.

Just a thought....
Its been a long time since I OCd my GPU but, some years ago I found that not always was the latest set of drivers to be the best for a card that is also not the latest!

So you are telling me to try a driver from let's say 1 or 2 years ago? will try and post back. Thanks.

Something along that line!
I found drivers 1,2 maybe 3 versions after release work best!
Once you get 2 to 3yrs after release the new drivers are geared more towards a newer model of GPU!
