Definitely a huge gamble. Probably not the most effective use of your money. Purchasing and holding coin would be better. You still need to pay for PSU, power cable, shipping, and customs fees with this unit.

They already tried.


I don't understand why you people can't wait. You'd rather that they'd just make up numbers and tell you what you want to hear, instead of getting everything squared away, and presenting you with accurate numbers/benchmarks. I actually appreciate a company that doesn't rush out data/info without verifying the accuracy. Nobody has to accommodate your schedule. Nobody has paid any money for these accelerator's. Having no patience is the reason there is so many scams on this forum.

A9 dashboard is broken. If you're getting 26% rejects poolside then there is either something wrong with your setup or your A9.

Actually people do care. That's why almost all the BCU's are sold out. If you need a youtube video and commentary as a substitute for your own due diligence, then why don't you just wait?

Suprnova is either having problems or upgrading right now. Was not credited for 12h worth of shares. Payouts to wallet working however

What are the improvements? Higher hash or lower power consumption?

No, batch #1 customers were expeceted to pay in full. They probably honored a few orders that weren't paid in full right away, but the 50% option was not offered until batch #2.

Shipping batch #2 too early would virtually guarantee that batch #1 customers would need to be compensated further than the $250 coupon. Batch #1 customers are already angry. I agree bitmain doesn't really care how mad their customers are, that is until it starts affecting their bottom line. If they ship batch #2 too early there will be absolutely no incentive in the future to be an early adopter of their products. Aside from the greedy folks, people will just start waiting for the discounts, and it will become hard for bitmain to gauge demand. Bitmain and innosilicon are targeting 2 different types of miners as well. Bitmain is targeting hobbyist/home miners/first time miners, whereas innosilicon is going after the "big fish". Not everyone is willing to take a $10k+ gamble, whereas $850 is a more acceptable risk/reward for most people.

I also doubt they've had time to assemble all the units. My guess a few weeks ago was 10k units in batch #1. My guess for batch #2 is a bare minimum of 25k units, possibly a lot more.





I've been wondering what happened here as well. There is probably an explanation considering they skipped over weeks worth of orders. Still wouldn't doubt that some people got lucky though.

It wouldn't make any sense for bitmain to ship batch #2 early. That being said, and I'm sure there is an explanation, it does seem like 100+ batch #2 units were shipped early.

Very interesting, can GPUHoarder or Senseless confirm this?

Too much negative publicity during z9 launch while they're gearing up for a massive IPO.

Will gladly test my unit when it arrives on monday. Only willing to dedicate ~20 min or so if the rejection rate is too high however. Will provide the logs though.

Sorry if this was answered already but I would like to make sure I'm understanding this correctly. So users who have purchased units will have the option to add water cooling before their unit ships? Any estimated price or lead time on upgrades?

I have a hard time believing that a 50+% stable overclock results in only 380w @ the wall. That can't be good for the failure rate. You can't overlock inno miners, but they do release firmware updates.  The A9 website says ±6%. The Z9 minis variance was ±5 when announced. What's to say that the A9 doesn't have a lot more to give if Inno allows it?

The absolute soonest bitmain could start shipping these miners is on the 18th. The first few days of shipments would likely be the day 1-3 customers anyways. Realistically people who didn't order in the first few days won't see their miners for 2 weeks at the earliest. 3 weeks is a lot more likely. Their official shipping schedule is from june 20-30th. I'm guessing 1000 units a day which would confirm the rumors of a 10k units in batch 1.

At 1500+ watts, massive increase in db/heat, and a reduced lifespan, yes. The A9 is 650w + 3 week head start for the first, day 1 orders. This is coming from someone who has 4 z9 minis on the way. Also, it's very doubtful, but no one knows if they have contain enough memory for the upcoming 144 equihash parameter tweaks.

Kinda weird but I also purchased 4 batch 1 z9's and 1 A9 ZMaster. Great minds must think alike (I hope)? I'm feeling more confident about my A9 purchase and less so about the batch 1 z9's. Bitmain got caught completely flatfooted by the A9 announcement. I think their strategy with only shipping 77 units was so they could get those early customers to hype it up via forums/youtube/blogs so more people buy into batch #2 thinking they're going to be earning as much as the first 77 customers.

Their strategy completely backfired. I think they're rethinking things right now, after all the complaints, and A9 announcement. It also doesn't help when a lot of those first 77 units got into coin devs hands.  I doubt they will give more coupons or double miners for batch #1 customers. I'm guessing firmware update or faster shipping schedule is their only viable option.

Resorting to semantics and ad hominem. You don't seem to possess the business acumen that you think you do.

Hi, how many units do you have left available?
