Ethereum update: Miner using dynamic memory instead of gpu memory
Hey guys, I got an issue where after I run a game for a while, when I relaunch phoenixminer it seems to be putting part of the DAG in dynamic/system memory instead of the GPU’s memory.
I’ll be using 634MB D3D Dedicated/34MB D3D Dynamic according to hwinfo while idle on my desktop. [Once I launch Phoenixminer, it will start off with 1954MB D3D Memory Dedicated/1485 D3D Memory Dynamic, with a hashrate of about 1.8MH/s.](https://i.imgur.com/YFuYmh8.png)
I let it run for a few minutes, and then it drops to [~310MB/~3191MB dynamic/dedicated and the hashrate raises to 7.1.](https://i.imgur.com/A6f88aN.png)
Then 150MB/3159MB and the hashrate climbs to 14MH/s. [Sometimes after running for a few more minutes, it will go to ~20-50MB dynamic/~3,342MB Dedicated and the hashrate returns to its normal 28.2MH/s,](https://i.imgur.com/p7NzRrF.png) other times it will sit with 150MB in dynamic for hours, requiring a reboot in order to recover the hash rate. I get the same result if I use Claymore to mine.
Sometimes, it will go from 1MH and high dynamic to full speed almost instantly: https://i.imgur.com/8dzcaDS.png
Is there a way to force it to not use dynamic memory so I don’t have to reboot to recover my hashrate?
