Why are you using version 9.5 to mine Zcash when Claymore is on version 12.5?
Another problem you have is that you are using the incorrect video drivers for Zcash for the RX4xx cards
and lastly 1913MB is 1.9gb's it clearly states in the instructions to change it to 16gb
Does anyone ever read the instructions before asking for help?
For 4xx cards (Polaris) Crimson 16.12.2 is recommended.
NOTE: For best performance on Fiji cards you must use 15.12 or 16.3.2 drivers. For newest drivers speed will be slower!
You can get bad results for non-recommended drivers, or miner can fail on startup.
Set the following environment variables, especially if you have 1-2GB cards:
For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:
"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".
Now if for some reason you are referring to ETH, then Claymore's version is 9.7, the drivers you are will work just fine but you still need 16gb of virtual memory
