Need to unlock max gpu temp R9 295x2

[RavenLunatic]

I am trying to overclock my 295x2 but catalyst control centre only allows a maximum of 75C for my card. Is there any app or register key I can amend to let the cards max out at say 85C.

The card thottles at 75C. I can see the gpu clock drop in afterburner when I run the heaven benchmark.

Seems to be throttling at stock settings too. 1018/1250
Tomb Raider using the settings in the benchmark thread.
Min 93.4
Max 153.7
Avg 120.3
left the benchmark running for a few min after the score updated and GPU2 was throttling.

AMD should have set it at the same temp as the 290x's. I don't understand why they made it soo low.

Is the fan moving on the radiator and the gpu?

Fans are working fine. I even added a pull fan to improve the cooling when I installed it. I might replace the AMD fan with a better one and see if that can keep the temps south of 75C. Other than that I don't know what to do other than RMA the card as faulty.

The card cannot run 100% utilisation at stock for more that 5 min. That seems to be a fault to me.

Err as it happens, nope the pull fan isn't pluged in.

Forgive me for asking but are you sure the second fan you installed is blowing the right way?

Luckily it is the right way round. few.


Doh, it appears I was wrong and the pull fan was not working since it somehow became disconnected from the MB probably when I replaced the PSU. So rage over, although the Max temp for GPU2 is now 72C in Heaven which does not leave much room for overclocking.

Thank you to everyone for helping me get to the bottom of the problem and I will look out for that new BIOS.

I have got mine mounted to the front of my case pulling air into it. I have a corsair SP120 push fan attached to the front which has dropped the max temperature to 70c, also replaced the stock fan with a corsair AF120 pull fan on the back.
BTW just in case you are not aware it is very likely your 4K monitor will not run at 60hz until AMD fix the drivers. It will however work ok at 30Hz for now.

 

[RavenLunatic]

By fans on the front and back I mean on the radiator not the case. I have other fans to remove the hot air from the case.

Can't hurt to try. I get a crazy mad flickering picture when I try 60Hz.
1080p @ 60Hz works ok for games and 4K@30Hz works ok for desktop use.
