Overclock Limit on AMD R9 380?

[Ahoo]

It has an MSI brand cooling fans on it (2 fans), with 2GB of VRAM. I'm using MSI Afterburner for my overclocking software.

How much should I clock the Power Limit %, Core Clock (default 980MHz), and the Memory Clock (default 1375MHz)? Fan speed percentage too, it's default 18% power.

I have 600W power supply, Intel i5-4460 3.2GHz, 8GB of RAM DDR3, and 2 case fans. Hopefully I supplied the correct information.

I want to overclock this to get the best preformance without putting it under too much stress. Not borderlining overheating, but somewhat directly between non-overclocked and clocked to the absolute max

Any help or feedback would be helpful, thanks.

Try upping the power limit to 110%, and try pushing the core clock towards 990Mhz, set the Mem.clock to 1400. Let the fan do its job automatically. If it succeeds, try benching the setup with RealBench or other benches that push the GPU.If it starts artifacting,then the card cant be OC'ed much further.

The biggest limit to OC 285/380 is the heat sink. Both chips should go to 1010 Mhz without additional voltage. The power limit should be increased 10-15 %. Not any real benefit from increasing memory speed. Not a good idea to cross fire these guys without additional cooling. The 73 - 75C when under load will eventually kill GPU 0. 285 will crossfire with 380, but the crimson driver will only let you control GPU 0. That means you can increase the 285 to the 380 speeds and that is it. 15.3 will let you control both of them, so you can OC both and match the speeds.
