What AMD driver version are people using? I'm using a fairly old one probably because I wanted one that works with OverdriveNTool and had noticed some of the newest ones don't. I'm using version 20.4.1 and with this driver and MoreEpochs v1.2 none of my AMD GPU's are able to create their DAG files.
I was testing with driver version 20.12.1 What AMD GPUs do you have? What kind of error did you get when gpu wasn't able to create DAG?
Rig 1 has a Vega 56, and an RX580; rig 2 has 3x RX580's - all are 8GB. I get the same error on all of them when I try to run version 1.2
Setting DAG epoch #387 for GPU3
Create GPU buffer for GPU3
GPU3 - not enough GPU memory to place DAG, you cannot mine this coin with this GPU
GPU3 - OpenCL error -61 - cannot allocate big buffer for DAG. Check readme.txt for possible solutions.
I'm guessing the driver version is too old and I'll need to go with something slightly newer, but I'm going to wait until I can get onsite to use DDU driver uninstaller and then update.
Anyone have OverdriveNTool running with a newer driver version - if so, which version? Thanks.
One user sent me .log with similar error:
GPU #0: Ellesmere (Radeon RX 580 Series),
8192 MB available, 36 compute units (pci bus 1:0:0)
gpu 0 max alloc size is

As you can see GPU reports 8192 MB of vram, but other api call returned value of 4048 MB which is not enough for 4.03 GB Dag.
The situation probably happens with specific models of GPUs or with certain version of drivers.
Can you check your .log file to see if there is same problem? Also what is your OS (Win7/Win10) and AMD driver version?
