Thanks for replying! Really do appreciate the time taken, and help offered =) Response below
I'm not familiar with Radeon mining, but from the error message, I think it is pretty obvious that there's a memory problem. Your graphic cards seem to have enough RAM (4Gb should be enough). Another thing you should check is virtual memory. Have you checked your virtual memory (Page Size), maybe there lies the problem?
As stated in my post, I have tried upping from 24000-32000 MB paging file to 32000 - 48000 MB. No difference.
Yes, I think there is some issue with maybe the motherboard, as the same error is for all cards in the rig, and isn't really anything pointing to this being a software issue.
The error message is pretty descriptive as it and all you have to do is as it says, "check your drivers."
If you really already tried DDU and reinstallation of latest drivers, I would recommend using the Aug. 23 AMD Blockchain Drivers. They should still be available for download online as they are pretty popular for their stability and use in mining.
Also, did you update your windows 10 OS recently? That latest update screwed up everything. Google ethermining and win10 update errors.
I really have tried DDU, and reinstalled drivers. Both new and old. Trying the blockchain driver now, haven't yet because 1. Newest worked fine before this issue, and 2. I have 10 cards in the rig, and the blockchain driver only supports up to 8 GPUs.
Win10 is not updated (disabled updates), and is sitting on version 1709.. this same setup, and versions works across all rigs I own.
