I’m experiencing a large number of discarded shares as well. I’m running on Antpool also. Initially mine weren’t showing any hashrate on Antpool but if you wait a hour or so it should start showing up. Mine started showing after a few hours. I’m wondering if Antpool is still in the process of updating their pool. I am also concerned about the large number discarded shares though.
Hey can you recommend any smart PDUs that show wattage? I’m using these now but they only display amps
Tripp Lite Metered PDU, 30A, 30 Outlets (6-C19 & 24-C13), 208/240V, L6-30P, 10 ft. Cord, 0U Vertical Rack-Mount Power (PDUMV30HV) https://www.amazon.com/dp/B0012VN0I0/ref=cm_sw_r_cp_api_4w5ZBbQZ3NQ0A
Edit: looking at my amp readout, overclocked to 14th/s, my miners are pulling 5 amps. I used that to calculate my watts and on 208v I’m estimating I’m pulling 1040 watts. Huge improvement even overclocked.
Ok so it’s an issue on Antpool’s end then. Mine are hashing as well but the hash rate is not showing on Antpool itself. Curious what your 13.5’s are hashing at? Mine are only 12.5-13th/s so the hashrate dropped some.
What are some results of this? My s9's keep saying incorrect firmware and it reverts back to whatever it was. Disappointing so far, I guess I have c5 boards? Idk. I'm trying it on older 14th/s s9s. I have some s9i's to try also but im pretty sure it said it wouldn't work for those at all currently.
I saw one guy reporting a 10-15% reduction in power consumption but I can’t verify that because I haven’t had a chance to update mine yet. He also mentioned that he flashed an S9i and the firmware is apparently working fine but again can’t verify that’s correct at this time.
Edit: he also mentioned hash rate remains the same or even improved on some of the ones he flashed with the new firmware.
I haven’t tried it myself yet but I believe people were having trouble with pools like Slushpool. I’ve seen reports of it working on btc.com pool and I assume Antpool will probably work as well. Maybe try one of those to confirm if it is a pool issue.
The new firmware works great on my S9s connected to the btc.com pool. PDUs reporting power consumption drop of between 10-15%. Hashrate reported at the pool is equal or slightly higher on all updated workers.
Note I accidentally flashed an S9i as well and it appears to be working fine but it’s probably best to wait for the ‘official’ S9i and S9j LPM firmware next week.
I just updated mine. Seeing ~13% reduction in wattage and the same or slightly higher hashrate (too soon to tell, will watch it over night). Mining to slushpool and all good but I waited till they said they fixed it for slushpool today.
is there a way to verify it's installed" I see a check box in the configuration that says " Low Power Mode " and it's checked off, is that the AsicBoost setting" If it is then i am getting less than i should be it seems. My S9 13.5Th\\s model is only reporting 9Th\\s and also has a lot of discarded hashses? (Accepted 65 Discarded 238 after 8 minutes of running)
“File System Version” will be set to 22 October under the system page after it has been installed. Interestingly enough, the default for me was for LPM to be enabled, which I understand to mean that overt ASICBoost is on.
Yeah I'm on BTC.com so it should br supported. Maybe it is just wonky on the 13.5th/s model. If I uncheck low power mode I get 13th/s. Funny thing is if I use Braiins-OS I get over 13.5th/s. I'm using 110v on it but I could still hash full power on Braiins-OS
>However, the ASICBOOST method has not been used by us on the mainnet.
I believe Bitmain's response to the ASICBoost accusation about as much as I believe Saudi Arabia's response to to Kashoggi's disappearance.
>Even though it has been verified by multiple third parties?
Had what verified? By whom? What's the source for this?
I'm saying that they may in fact have used covert ASICBoost on mainnet, contrary to their claims.
> Our ASIC chips, like those of some other manufacturers, have a circuit design that supports ASICBOOST.
Has been verified by, for example, Greg Maxwell:
> Reverse engineering of a particular mining chip has demonstrated conclusively that ASICBOOST has been implemented
(Sure, he doesn't name Bitmain, but I think it's widely accepted that is who's chip he was referring to)
It's also more recently been verified by Slush/Braiins OS - https://medium.com/@braiins_systems/bitmain-antminer-s9-asicboost-capability-verified-by-braiins-13-in-energy-savings-and-planned-da67c290152c
Why do you not believe it? Or have I mis-understood and you really believe Saudi Arabia's response to to Kashoggi's disappearance?
Yes, I absolutely believe that their chips support ASICBoost. No, I absolutely don't believe that they've never used covert ASICBoost on mainnet while mining with their own equipment. I feel like you'd have to be incredibly gullible to believe that claim.
> This implies that all Bitmain patents are now open, right?
No, it does not. I think you are trying to manipulate with your insinuations.
The fact is that there is [prior art](https://en.wikipedia.org/wiki/Prior_art) covering what is now referred to as "AsicBoost". This should be the primary and expected reason why they would state that "there isn’t and may never be a patent right over AsicBoost" (note that it does not state *anything* like "there *is* a patent right, but it's open to us now").
It is not on me to prove this! It is on the ones claiming patent rights (be they "defensive") to prove their claim which would imply that no one ever had the common sense to apply the obvious general technique in "AsicBoost" that is about as old as block ciphers.
Well, Bitmain are clearly using the patented technique, they even call it by the same name. The instant they start using the patent, they get subject to the licence, which means that other licence subscribers are free to use any other Bitmain patents freely. It is really as automatic as that, and it can only be avoided by invalidating the Asicboost patent. So, in any case, it is up to Bitmain to prove that.
Prior art (state of the art or background art), in most systems of patent law, is constituted by all information that has been made available to the public in any form before a given date that might be relevant to a patent's claims of originality. If an invention has been described in the prior art or would have been obvious over what has been described in the prior art, a patent on that invention is not valid.
Information kept secret, for instance, as a trade secret, is not usually prior art, provided that employees and others with access to the information are under a non-disclosure obligation. With such an obligation, the information is typically not regarded as prior art.

Their article says:
With regard to patent rights, we continue to respect third parties’ IP right and take actions accordingly. Based on legal opinions from various jurisdictions, we believe that there isn’t and may never be a patent right over AsicBoost. Thus, all miners should be entitled to make their own choice on whether to use AsicBoost technology without anybody having an exclusive right over it.
And if you need anymore proof that Bitmain is effin their customers over, this should do it. The S9 had AB since it's launch, but you, as the customer, couldn't use it. They, in the other hand, do you think they used it???
There is also the longstanding suspicion (first voiced, I think, by [Greg Maxwell](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-April/013996.html)) that Bitmain was making use of *covert* ASICBoost.
Your post reminded me of a History of Russian Rulers podcast, Russian history from way back in the day all the way through to now, when he got to Stalin's time he talks about Stalin's various *friends* over the course of his career, and where they ended up. Definitely got the impression that Stalin at a very fundamental level didn't really understand friendship.
Braiins today revealed that they verified the existence of AsicBoost-functionality in Bitmain’s S9 ASICs. For unknown (but possibly patent-related) reasons, this feature is not made available to regular users, however. The Braiins team plans to unlock this feature with BraiinsOS, which would mean that Bitmain S9 owners will be able to increase the effectiveness of their machines by more than ten percent."
Bitmain would pretty fast lose dominance on their own firmware.
