Bitmain Release AsicBoost for T9+

[thierry4wd]

Hi, bitmain come to make public AsicBoost for Antminer T9 +!

I just tested it, and it's a disaster ... 4.5 Th / s for 800W !!! I had to go back on a stable firmware without asicboost ... (with no dificult)

It would be interesting to share your opinion here;)

Have you tried to reset it to factory default after the upgrade?
You can reset the t9+ by holding a reset button or holding IP report button for 15 to 20 seconds or check the guide from here https://enforum.bitmain.com/bbs/topics/3957

If you don't reset it before you run it there is a high chance that the firmware will not run properly. So, by resetting it to factory default the miner will refresh and the program will run properly.

Same....starts at 4.5TH then over and 1hour, raises to ~7TH.  Restored to default.  Same problem.

Same problem here, hope they fix this.

It works perfectly on some of my T9+ (around 1100W), but it either decreases the hashrate or completely stops hashing with few of them.

Same problem. My T9's now around 9,5 Th/s.

i'm thinking no asicboost at the moment ... bitmain is talking about "reduce power comsuption" but at no moment of asicboost ... so in my opinion no asicboost but just an improvement in efficiency ...

I also achieve the same performance just by moding the bmminer codes,

With their bmminer "lpm" the core open at 810mv which is far too little, and which is clearly planted chips ... they must open at least 910mv (original 930mv) ... I tested the downclock and no more problem ... but hashrate very low ...
