Have you manually messed with different clock speeds in any programmes like MSI Afterburner or did the problem just came out of nowhere?
If you have just reset the clock speeds to factory settings(there was an option for that I think).
I didnt even know there was a bios switch on the card ill look for it. Thanks
These bios switch (on 290X) used for fan mode (silent mode or performance mode)
Silent Mode
Will be giving you a quiet fan (The fan runs at low speeds)
Performance Mode
The fan speed will be dynamically adjusted based on the GPU temperature to keep GPU temperature lower for the best performance.
