Hi,

New user on the forum, thanks for having me =)

Having a weird issue with one of my rigs
PhoenixMiner/Claymore it seems to show the same issue, but Claymore has more information, , tokenminer even more (see error text in bottom of post)
Seems to do with the miner not being able to save DAG to GPU memory? Maybe not purged after previous session?
10x 4GB RX570s, the machine has 8GB of RAM.
Running Win10 with latest driver.
Tested with Claymore, Phoenix, tokenminer, ethminer - Clearly not a miner issue
Testet reinstall driver (with DDU), reboots and increase of swap file to 32GB+.

Anyone seen this before?
error text :
In PhoenixMiner: unable to use opencl device radeon rx 570 series for ethash mining
In Claymore: unable to use opencl device radeon rx 570 series for ethash mining / OpenCL error -61 - cannot allocate big buffer for DAG. Check readme.txt for possible solutions.
In tokenminer: OpenCL device Ellesmere has insufficient GPU memory.536870912 bytes of memory found < 1073739904 bytes
of memory required
In tokenminer: No GPU device with sufficient memory was found. You may need to change the --opencl-platform argument to 1. (this changes nothing BTW)
