24 chip (6 chip chain x 4) test result posted.
The mosfets and big capacitors are safely removed due to the constant workload of BE300.

Results:
273.60GH/s | 0.38W/G
176.64GH/s | 0.31W/G
155.04GH/s | 0.27W/G
118.56GH/s | 0.26W/G
With more accurate control on the variance between chips we could in principle gain less power consumption in advance.
great work friedcat! my prismas are working very whell and whainting for your new release!
