Antminer S1 Upgrade Kit

[Bitcoin++]

Bitmain promised some time ago:

Will there be S1/S2 upgrade kit and what is your plan?

Yes, there will be upgrade kit for both S1 and S2 customers. But we need some time to design and test it. After we have finished the homework, we will announce the plan publicly.

Has anyone heard anything about when it will be ready and how the kit's specs will be like?

Both it will replace the current chips with new ones. But the issue is then you have left over blades that are not running and are useless.

Or maybe the upgrade is twofold:

1. Undervolt / underclock the existing boards.
2. Place secondary boards outside the existing ones. If you look at the S1 you'll see that these can easily be attached to the frame. These chips will need to use little electricity and have big heatsinks as they will not have any direct fans.

Since PSUs and S1 are dimensioned to 400W+ and it uses only ~100W after undervolting I believe it is doable with secondary boards as described. However, I'm afraid Bitmain will overprice these too such that there's nothing to gain.

EDIT:
Secondary boards may also be placed under or over the antminer such that these too are directly cooled by the fan's airflow.
