I get black screen (pc freeze and have to reset) Heroes of the Storm and Path of Exiles

Tested with 17.9.1, 17.9.2. 17.9.3,17.10.1 ,17.10.2, 17.10.3, 17.11.1, 17.11.2, 17.11.3 and 17.11.4


The black seems to happen random when the memory jump between 167MHz and 500 MHz, while playing Heroes of the storm, path of exiles most likely other games which have low load on GPU.

Found a workaround by changing the powerplay ucVddind from 0 to 2 for Mem Clock 2, to give a but more voltage to the memory at 167HMz, but it result was that the card idle at 500HMz and never go to the 167MHz memory clock. not seen any black screen with that reg "fix".


A second work around is to run Furmark on 2nd monitor, while playing which also prevent the card to use 167MH on the memory.


Updated the BIOS on the card from 102 to 104, din't help


The Card is stable in Black Desert, Hellblade, Cities Skylines, 3D Mark, Heaven Benchmark, Furmark, even with some overclocking/undervoltage. But the 167MHz memory clock give problems in "3D mode"


As it posible to "fix" with powerplay profile, it could be a Bios issue.
