How loud are these miners?

Presumably as loud as the S7 miners are.

Indeed they are or as loud as any of the new ones from but main around 76 DB . but you can either make a sound box or buy one off ebay and run it at 100 % an even over clocked it if you want in the box the DB drop to normal levels or were you can sleep in the same room . I made a sound box /hotbox whatever you want a call it for one of my D3's and it works Great .....

My electricity rate up here in Canada is 0.04 kWh so I should definitely be seeing profit.

yes you should right now till id say some time into the 3Q of this year, it won't be much you might even hit ROI if that's your bag or worry because of the price of the miner an depending on what the Diff stays at with them testing new stuff . . with solar it's the same just watch the meters with solar an the disconnect to the power company at nite unless your off the gild  .  . if your power is high without using solar .

The price on these things have really come down.  I just bought a used one for $200 and an APW3++ for $200 off Amazon.  This will be my first foray into bitcoin mining and from the research I did there really isn't any cheaper way to get 4TH/s than an Antminer V9.

an yes again i can't believe there is fools still selling S7 for more then the V9  i just hope whoever buys these things shops and learns not to buy a S7 when the V9 is basically a S7 at a lot cheaper price. it amazes me the greed of some... when there is more then enough to go around .

Hi Guys,

Thanks

We've lowered the price for brand new individual AntMiner V9s to match Bitmain's pricing @ $291.00 each on our Amazon store with free shipping within the US. We also have them on eBay for $309.00 each and our own site for $291.00 each (for crypto payments and international orders).

Awesome. Ty.
Perfect for hobby miners, schools to use as a teaching tool and those with .05/KWh or less.

Does anybody know of these use voltage regulators/buck for the chip voltage or are they set up with string voltage like the S5 was. If using string voltage you can use a step down buck converter on the out of the PSU to run them at a slightly less voltage (11.0v-11.7v) and under clock for better efficiency/heat/noise.

Something like this
https://www.amazon.com/gp/product/B0747QDRW9/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

You would have to use 3 of them (1 to each blade) and under clock but could see some power savings. Just a theory.

Thanks for the answer Dave!

I did order 10 of these, with the idea to downclock them and run them more silent.
Well, if I can change the freq. and fan speed I can try things out myself Smiley
Did some basic testing today. Looks like it's a even drop of power as you drop frequency at least on the one I tested.
There seems to be a lot of variation in the units in power draw and temp. Between the best and the worst it's close to 20%

On the one I tested if you drop the frequency from 600 to 500 you drop the power used by about 15%
I could get it cool and almost silent by dropping the frequency to 412 and only running boards 1 and 3
It's only 1.8T to 1.9T at that point but I could run the fans at just under 3K RPM and it was still cool.

I'll test more tomorrow if I have time.

Is it possible to change the frequenty and fan speed of this miner and make it more silent like an S7LN?
 
Yes, fan speed is on the main settings page.
Frequency is on the advanced settings page.
Even at low fan speed it's still loud.
I have not done any testing yet to see about power savings with the lower frequency.

I would suggest no one buy this piece of trash right now. Set to a static IP and then lose access to a 600 dollar investment. Now I realize it's a toy but imagine you set your Android phone to use a static IP and then you couldn't access it without rooting and all that BS.

Then imagine the links the company gives you are just files and no instructions or anything. I can't wait for samsung to drive these hacks out of business.

Does anyone have instructions. There are 3 different firmware downloads for the v9 on their site and none of them are the same. It's been sitting here a week n a half and I am just about ready to file a chargeback and throw it in the dumpster. Completely insane.

Do I need to use the diskimager program and write the s2s4 image? It would appear so as that is in their tools and instructions downloads but who knows.

Yes, burn the SD with the V9 image that is on that page and put it in the sd slot on the miner.
It should get a DHCP address and you can go from there.

The failing when setting to static seems to be a bit random. I have done many with no issues.
Some people have had 1 or 2 not work.

Ok , chked the router and got the ip,   I type ip into explorer and get nothing. on the miner there is blinking greenlight, on the nic caed only yellow light no blinking green light.
i have downloaded BitmainMinerTool and it can not find the miner ether.,,,,,,,,EDIT    I got it up and running now but I do not see any way to set to load balance or rotate....is this a flaw or is there an update that i need?   2nd EDIT.... there seam to be a high # of "discarded" to "accepted" about 2 to 1 ratio.  any ideas?Huh oh and what is the acceptable temp range for these units?

IIRC Load balance has not been on the miners since the S5.
Now it just fails over to the next one.
As of now I am at 54,205 accepted and 319,784 discarded on the one miner I have here.
Those numbers will depend on what pool you are mining at.

I have been making sure not to set the ip.... there is a new firmware out on the 12th ,,,, it should address the issue but i have not heard of a confirmed upgrade or the setps to do it right
you think they would put out a manual whit some basic how to's..... if anyone has done this and know the steps please post......I have heard of someone unbricking there V9(look up a few post) by flashing via sd card.....This is the link they gave...https://shop.bitmain.com/support.htm?pid=007201604120945219855QObfk20066C    ,,,,,I hope this helps you. and let me know how it goes... I want some fetures back like load bal.

Just got my new V9 and I need to know how to access it, to set it up. I know not to set static ip til I update.
but with my S3 i just type in the ip address and im in, but how do I find the address for this V9?


You can either log into your router to view the list of connected devices (dhcp table) or you can use an IP scanner. I prefer the router method since there is no additional software required. If you choose the IP scanner method, I would recommend using www.advanced-ip-scanner.com.

IT WORKS!! Managed to flash Firmware by loading the files onto SD card.  Once loaded, found IP throught
the IP report button.  Set to static again, this time no problems.

Mine on!
Glad it worked. Grin
