Each Miner will be insured and signature will be required.
I added front fan grills on each miner
Both have the original firmware, which requires the use of the manual fan setting.
The batch 1 is rated for 4.86 by Bitmain @ freq 600. I run it at freq 625 and it averages 4.9 on slush using ~1260 watts.
The batch 2 is rated for 4.66 by Bitmain @ freq 575. I run it at freq 625 and it averages 4.9 on slush using ~1320 watts. It does run hotter and uses ~60 more watts than the batch 1.
I run these on EVGA 1300 G2's on 120v; I have never tested them on 208v, 220v or 240v so I am not sure if they would perform the same with those voltages or with another PSU.
With these early batches ( at least with 120v power) they have less errors ( and thus a higher hashrate ) when you run them slightly hotter with a lower fan percent. In my experience these run best at ~62C.
With a 70 degree F ambient I run the batch 1 at 30% fan.
With a 62 degree F ambient I run the batch 2 at 30% fan. (40% with a higher ambient.)
You MUST only use 1 PSU per hashblade. Bitmain has made it clear that damage is likely if you fail to do so.
You MUST use 3x pcie per hashboard ( not worth the risk, just order some splitters off amazon if you don't have enough pcie)
You MUST power on all hashboards before the controller (if only using one PSU you avoid this problem)
Each miner requires 10x pcie connectors
If you need a PSU I can also sell an EVGA 1300 G2 PSU ( each with 2x splitters + a jumper ) for 0.3BTC each shipped
Note: these only work well for 120v power with the S7's. If you using 208v, 220v or 240v you should get a different PSU.
