user rockmoney who sells these, has been mining/testing one of these on and off on my pool over the past week,

Here's a test run today:

Continuous mining for a single mining clientid on the pool - stats today for 4 hours ...
From 2019-04-19 22:00:00 -> 2019-0420 01:59:59 UTC (4 hours)
Shares submitted - 915 accepted shares
Total Diff accepted - 3232896.0

So to convert that to a hash rate: Diff * 2^32 / 4 hrs
3232896.0 * 2^32 / (4 * 3600) = 964.25 GH/s

I'll await his post of the settings he used.
