Topic: Bitmain registers S11, S11+ and F3 with Russia FSB Protocol (Read 2287 times)

Hopefully this is on topic here but antminer list the apw7 psu at 1800w. so maybe s11 has a 1570 draw? and 19-22 th/s?

There's also the thought that anyone paying attention would know a fivefold increase in efficiency from one model to the next didn't really even happen back when ASIC mining was new and still working down from 130nm. When someone suddenly comes out with a machine that's far and away better than what everyone else has, it is ALWAYS a scam. Especially if it's in anywhere near the same price range. Obvious ploy is obvious (and oft repeated).

Double especially when the company claiming to be releasing it has been hacked, and sent you an email saying they were hacked, and then sent you an email saying the miner rumors say they're selling in fact does not exist and you should not buy it.

Bitmain's database was hacked a while back and the hackers got everyone's name, email, phone, address and who knows what else.
(Yes Bitmain also stated this)

There was a thread in the hardware section warning everyone about the new fake S11 email in the last 24 hours.
Alas the mods deleted it - go complain to them

Seems i just lost 4600$... For f***ck sake f**ck this s*it, they had all my informations! Email, phone, adress, street, everything!! Never ever i will buy from bitmain!!

Customer details

Goes on with my shipping info from bitmain. Looks like the email is spoofed as well.

Is starting to feel like S11 units are being tested somewhere.....

This email (or any other explanations they made) didn't deny S11's existence by the way. They only said its not Bitmain who's been advertising/taking preorders for S11's.

There is a huge difference and yesterday they started to dump their S9's completely on us. Who's stupid enough to buy S9's right now?

Email from Bitmain overnight:

I think they have mine let me check my account.

Why would Bitmain have your phone number?

I just got an automated phone call claiming to be Bitmain.  It told me about the new S11 miner that will be available on June 10th and as a valued customer I will be allowed to pre-order up to 50 of them.  There was no mention of the hashrate, and I have no idea if it was really Bitmain calling me, but it did ask me to confirm certain information that only Bitmain or someone who had hacked Bitmain's user database would know...

The cooling of multiple tiny heatsinks isnt even especially on the s9’s since they r often put on at varyin angles making airflow harder. Some chips will get more cooling than others. With a solid one the fins would be in a perfectly straight row and it would have the added bonus of transferin heat from other chips that r hotter to chips that are running cooler. It doesnt allow the density like sidehack mentioned and im not sure ne one likes the epoxy idea. I liked the old screw and tension spring method but they get paid the big bucks to design these things not me. Even so many do agree about the epoxy part lol.

And epoxied-on single heatsinks make a miner unmaintainable and unrepairable. They're great if you want super high density, but super high density increases the chances of failure - so you'll need maintenance and repair.

Avalon6 had issues in part because of unreliable pressure for adequate surface contact, and by design an increased risk of shorting through the heatsink. The chip design also still pushed a lot of heat into the PCB which may not have been handled properly.

I think the primary reason Bitmain switched to individual heatsinks, besides being able to pack stupidly unsustainable density, was to decrease the risk of shorting across voltage nodes in a string configuration while still allowing both top-side and PCB-side cooling. There are other ways to handle it, but you have to admit having a heatsink soldered to the PCB is about the best thermal contact you can get.

Of course, you don't need that good a contact if you aren't operating at 6KW per cubic foot.

I tend to prefer solutions like the S3 and New R-Box utiilized, where the PCB was sandwiched between monolithic heatsinks. This ensured even mating pressure for all chips, plus heat dissipation from both top and bottom. Both those miners used low-volt parallel VRMs rather than string topology, so additional care must be taken to avoid shorting, which will likely reduce thermal coupling into the bottom-cooling heatsink.

Individual heatsinks only have more surface area if you design them to have more surface area. Look at the S1/S3/S5 main heatsinks for reference.

A solid heatsink is a terrible idea. It holds its thermal load much longer than individual heatsinks and has less surface area to dissipate with. Go check out the Avalon6 if you want to see exactly how NOT to design a heatsink.

U r partially right...they r one of the best out there speed to power wise at stock speeds which isnt achievable with other machines right now but to be fair others r close. I personally dont like them and have made that known but halong has a miner that can be underclocked even if it is cheating with asicboost and not pure hashrate like the s9 is. If bitmain has the s11 in hand and r plannin on sellin them soon that would blow every other miner away for probably years to come again. So far 2 other makers that i know of tried 10nm chips and both were unable to beat the 2 year old antminer s9. No one can deny that holdin that title for 2 years deserves a pat on the back.

With a new antminer i hope they return to a previous design with a solid heatsink with actual thermal paste not thermal adhesive like they have been using since the s5+ miners. I know it will take up some more space but the ability to use high quality thermal paste and have quieter fans with more even heat distribution (since the heatsink will be 1 solid piece all the gaps between the current design would help evenly spread the heat over all the chips instead of just that 1 chip) would deff make up for that added space in my opinion. I know others in data centers r more worried about density and the more they can pack in the more they make everyday but in my care im strugglin with findin enough power to run all my machines...i have the space...tons of space but not enough breakers in both locations to handle the load of more machines so i have to figure that out or stick with the 2 locations i have now :/.

To add, these people did not have pre-orders for other machines such as the E3,Z9, B3, etc. They dont seem to have inside information on other machines but they have it on S11 lol. Also the BM1387 is the T9/S9 chip lol.

It is possible that there is an S11 but if bitmain release an S11 now, alot of people will be pissed. They dont have any real competitors right now for bitcoin anyways. S9 pricing is too good to pass up against competitors. No reason to release an S11.

"resellers" - yes, as in those who resell them on ebay, Amazon, etc. However they are NOT Factory Authorized re-sellers such as Canaan has set up.
Huge difference in that non-FA resellers means ZERO FACTORY WARRANTY if you buy from them and the miner goes titsup. Maybe the reseller will help but odds are not because Bitmain only gives support to the original purchaser/user and does not support equipment that has been resold.

Factory Authorized distributors like Canaan uses means that if there is a problem both the distributor and Canaan will back you up with full support/warranty. And btw, for Avalons that is a 2-year warranty.
Personally, if I'm spending several thousand $$ I damn sure want a warranty!

Note that I said 'official' discount lol

Really now?

3% is the max official discount they offer on large orders.
