Holy crap did you say 3.2TH? 725MHz should see 2.9TH but that's still pretty nuts. The main regulator should cap at around 120 watts output.

Ohh now i see why i get flat behavior after 700mhz, the power i am measuring includes the axial fans and my RBPI to get to 725 i push my fans to 70%, i assume these are the extra 20w.

This is what i see:
- 725 not stable at all- got 3.2 for 3 minutes then crashes down to 500Mhz and as it reboots and reboots Hashrate became to 800G but power never came down. Temps on heatsinks were stable at 45 degrees celsius. I set anoush pull using original in front and exhaust acial at 50% the front i put it on tilted position resting on the cables and pushing the air towards the board (i guess at 45 degrees of angle) that caused higher heat efficiency and took the heatsinks to stable 36 degrees celcius BUT 0 effect on stability and power got to 138 ( the 3 wats i assume got from the added fan). same 3.2 then crash the 800.

-700 push pull stable on 2.7-2.8 i did not saw these going higher than that after 24 hrs, temps stable on 35 degrees the hottest spot. consumption still high 135.

-650 the current i have only pull acial at 2700 rmps silent ops, stable 2.57- 2.6 T @ 114.5w consumption net that is quite great vs other setups as looks close to 45j/t and the others were like 50.

something is wrong at 725, i have no idiea what to change ( but not sure if changing stock voltage will help) i dont want ro fry them.

so we can say 3.2 is not valid as they crashes after little time so to me at least not messing up with voltage 2.8 is the top. i am converting to water cooling but as i saw heatsinks on 35 degrees and no improvement i dont expect it to change, same as i want it to run 24x7 650 will give better efficiency and longevity.

i am on my iphone so cannot paste the chmkner screen but miner.php and looks ugly but here it is at 650, close to 24 hr run.
