Hi Guys,

So I was greedy and decided to go for an extra 50MHz on my core clock of my MSI R9 390. To get it to 1150MHz. It was perfectly stable at 1100MHz with +19mV on the core.

Anyways, 1150 was stable enough to run 3DMark 11 with no artefacts, but when I loaded up my miner, the monitor didn't detect a display input about 2 minutes into the mining process.

So I rebooted the PC and it would crash at the welcome screen. Me ****ting myself, I attempted to boot into safe mode (which isn't easy on Windows 10 UEFI with an SSD) after multiple attempts, I got in. I used DDU to uninstall the drivers and then rebooted into normal windows.

Normal windows with no GPU drivers worked fine - no crashes. I try to install the latest Crimson drivers and it crashes during installation. I then reboot into safe mode, use DDU, then boot into normal windows and use the 'update driver' option in device manager, pointing it to the C:/AMD directory where the crimson drivers are extracted to.

Installs fine and everything is hunky dory.

I play a game for just over an hour and no crashes (at the overclocked 1130MHz core with +56mV). Later on, I boot up the miner and it crashes again. Did the whole process again and tried this morning with the 1100MHz core and it crashed again.

I am yet to try the stock 1040MHz core, but what's going on here? Why isn't the GPU stable at 1100MHz anymore?

Thanks for taking the time to read this.

UPDATE 1: Happens on stock settings too. :/
