Antminer V9 4TH

[microtechies]

Had mine arrive today, only tested one so far but Nicehash only works for a few mins then doesn't pick up anything and Slushpool gets around 45% rejected shares rate :S

Will test the others tomorrow

BTW yes I have updated the firmware to the latest version

I don't know if you have any other miners or have set up any other ones but:

1) Check your power supply. These things need a lot of good power, a cheap 1200 Watt unit will not hack it.
2) Check you network connection. Could be something there.

If both of them are OK start checking the other miners as you said. If the others are good then it's just this one then it's a Bitmain issue. If the others are acting the same way, post again. There are enough of us here that we can probably figure it out.

Thanks I will do in the morning,

Just to let you know I'm not new to mining just don't post allot on here, I have quite a few Antminers & GPUs rigs.

Using Bitmain APW3 PSU & Network connection is fine.

I will test the others tomorrow and post some screenshots

Great news.

Is there anyway in updating the firmware when there is no access into the miner interface??
Could there be a way via using an SD card?

Yes, it's on the Bitmain website:

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!

Thanks once again 👍🏼👍🏼

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.

[goodgryphon]

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? oh and what is the acceptable temp range for these units?

[supracoinman]

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.

[goodgryphon]

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.

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.

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.

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.

[mammon]

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

[CryptoCrane]

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).

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.
