RX 6750 XT --> Resolution bug and High Temperature <-- HELP PLS

[rafael.barros.souz15c902e9]

Hi,

I just bought this graphic card and I'm not really happy at first:

- I think that the resolution is kind weird, I don't know how to explain but it is worst than it was with my gtx 960.
- I played The Witcher 3 to test the power of the graphic card and it got too hot, my computer's air circulation isn't 100%, Im gonna take care of that buying a new fan, using 4 fans to put air in the computer and 2 for air output. But I would like tips on how to optimize the card's temperature without losing performance... I heard about undervolt, what do you recommend?
- Sometimes the frame rate of the computer is low doing normal things, like just using Google Chrome.

I'm confused, probably I'm doing something wrong. Please help me!!!

OBS: my power source is 750 watts

This is my config:

How hot is too hot
Increase Fan curve using AMD Software
Same for Undervolt

Hi,
Thanks for your help!

Meanwhile I was waiting someone to help, I formatted my computer hoping that the nvidia drivers were conflicting with the AMD ones, which could be the solution. Unfortunately nothing changed.

And I noticed other occurrence: When Im watching youtube videos, the video lags sometimes even flickers and the audio gets a low quality-> the audio continue but the video lags and "jumps". Similar when when the web connection is bad (but connection is fine).

The resolution still weird.

The undervolting Im about to test it, and I have bought 3 new fans to help and the refrigeration.

So what do you say? My only fear is that the gpu has a fabric error

Updating your Motherboard Bios may also Help since your running on a 3 year old one

Hi Alan!

I did that too, nothing changed. Still something unregular.
One thing that helped was changing the DRAMs to work at single channel (but today the screen started to freeze again).

Last night I played I tested at 3DMark everything was fine. And them this happened today (this happened another times but stopped for a day):

Green screens when I'm watching youtube... lag screen... I can't send the complete video by here...

Sometimes the 3dmark tests did fine. What worries myself is the inconsistency

Im seding it back to the store that selled me. Maybe I'm going to get another of 6750 xt model or buy with a 3060ti.

Thanks for you entire help!

Can you test the GPU in another PC?

OBS: my power source is 750 watts

Brand and model? Do you have another one to try?

For some reason your CPU is spiking badly
Gpu is not too bad under Load

Make sure all Drivers are up to date Chipset mainly
