Guys, problem solved!
An extra stick of 8gb ram solved the issue.
Currently running stabily on 12gb ram + 180gb virtual.
Took off the extra SSD drive.
Will update in 48 hours.
Thanks for all the suggestions.
Yeah, I suspected it needed more Ram. 4gb isn't enough these days. In my Biostar TB360 2.0 I needed 16gb minimum to handle max gpus.Good job, let us know how things are going.
All my rigs run on only 4gb ram, including 12 units that are 13 gpus running on H110s. I run linux mining OSes and they work find on 4gb. Windows probably requires more as everything windows requires more.
