Unable to underclock Gigabyte R7 360

[otamaglimmer]

My card (Gigabyte R7 360) comes OCd by default, and I've always had to underclock it near defaults for it to be stable. If not, the driver/card would crash after being under load for a while (i.e. gaming).

I used to do this with OC Guru II, but since the crimson drivers where introduced it stopped working.
Now I'm trying to underclock it with MSI Afterburner, but every time I hit apply, the computer crashes and I have to reset it.

The AMD Control Center is also buggy for me. When I launch it, screen starts flickering going back and forth to a black screen. The only solution when this happens is to reset too.

Here is some info on my computer:

• 
  ■ Windows 10 x64
  ■ Motherboard: Asus A88XM-E
  ■ CPU: AMD A10-5800K OCd 4400 MHz
  ■ RAM: 16 Gb DDR3 1866 MHz
  ■ GPU: Gigabyte R7 360 @ 1200 MHz
  ■ GPU Memory: 2Gb @ 1625 MHz

And some more:

I need to get GPU around 1000 MHz and GPU mem under 1500 MHz.
Any idea or suggestion?

The problem (and solution) is the "Wattman" app in the crimson drivers. It over-rides other programs, so you need to change it to control the maximum clock speed.
So open the AMD graphics settings and click on the "gaming" tab, all your installed games should be listed, the top left one will be "global settings" click on it. Up the top there are two tabs, click on the "Global wattman" tab.
Now you'll see two graphs (one for gpu clock speed and the other for memory), each has a slider underneath, simply reduce the clock speed of your gpu by the percentage you want and click "apply".
You're welcome.

Thanks for your answer!
The thing is that I can't launch the AMD graphics settings. As soon as it opens, the screen flickers to black back and forth. Nothing can be done once this happens, but to restart.
Right now I don't even have it installed. I uninstalled the drivers with DDU and reinstalled without the settings app.

By any chance, does the graphics card have a switch on it, one position for oc performance and one for normal?

I just looked on the Gigabyte site to see if the card does have two BIOS settings....it didn't say. Anyway, I see they have old drivers for the card (up to 2 years old), while it's not ideal using such old drivers, it's better than drivers that crash your card. https://www.gigabyte.com/Graphics-Card/GV-R736OC-2GD-rev-10#support-dl

Hello again.
No it doesn't have any switch at all.
Here's a couple pics from the internet. Mine's just the same.

I'm not sure what you mean with having two BIOS (on the same card?) but yes, I could use those drivers. It's just I'd rather find any other way around...

What I mean by two BIOS settings is, the cards that have a switch to change clock speeds do it by having dual BIOS, one normal the other overclocked.

Anyway, I have found a solution that should work for you, and I'm surprised no-one else here mentioned it as it's a program often mentioned here. Use "MSI Afterburner", it seems to override the wattman app. I just tried it and was able to change my clock speeds despite wattman being on. https://www.msi.com/page/afterburner
