Question for the experts: Antminer V9 running at 450mhz and an APW3++ pulling 891W at the wall at 120V (80% rule for the PS) If I add another AP3W3++ and hook it up to two hash boards and use the original for the other hash board & controller will this be OK? I understand that the PS with the two hash boards would have to be turned on first, followed by the other PS with the hash board & controller I don't have an option to run 220V in the garage The garage circuit is on a ground fault circuit breaker in the panel and the only other load is the 8W LED post light along with the outside plugs which are not used. Safety first o/c You can use two PSUs but that sounds like an overkill. One APW3++ is perfectly fine for the V9.

I thought so also
At 600mhz the KillAWatt meter showed almost 1200W at the wall
The APW3++ is only rated for 1200W max for 120V
At 450mhz I'm pulling 891W which is approx. 80% of the supply's capability at 120V
I don't want to supplement with a PC power supply also

Has any one looked at the control board on a V9? It is a single board without the piggy back board most of the S3, S5, S7, S9 type controllers have.
New design maybe = new problems.
Thoughts?

S9's have been single board since batch 17 up through at least batch-25 which are the last I bought. Bfore that Bitmain used Raspi's and BeagleBones plugged onto a FPGA/other functions board. When they changed to the ARM Cortex SoC's that single chip took over all functions. I left Bitmain when they stopped accepting BTC as payment last year. Ja they've since blinked and once again accept BTC but I don't care. Been getting Canaan's Avalons ever since and am much happier with them.

Looks like the 9 series of Antminers and maybe more use LightTPD web server software in their control board software. Found this after reading up on the fault I get -- LightTPD Unauthorized
Appears that sometimes the web server is looking for id / password prior to moving on to the Antminer web pages.
Any one have any ideas of what the default LightTPD id and password might be as used in Antminers. I have tried all the options available using root and/or admin = no go.

This saved my bacon with a V9 today when my password no longer worked https://bitcointalk.org/index.php?topic=3314603.0The timing noted for resetting is very important My Antminer's IP changed also upon the reset I'm assuming the reset button does work on some V9's, hopefully most

Anyone lose a hash board on one of these yet?
Lost one last night and no doubt due to the recent and ongoing heat
Not worth sending back to Bitmain as I have $175 into the machine
Options: 1) Leave it in unplugged, maintain air flow as designed 2) Remove and look for obvious sign of failure, bad cap, etc 3) Purchase new spare for $135 and keep for parts machine, fan's hash boards, etc
Being old tech in design, might be better to leave as is and let it run itself down I don't have a rework station or other higher end gear/experience so not an option either

Great topic I have 10 of then V9's upgraded from s3's as a home miner but found quickley that I could not run them dew to the noise I am currently looking to find suitable premisis to house the miners.
I noticed the firmware has changed and no longer do we have as many options in the gui from say the s3's.
What is everyones take on the clocking of them? Has anyone tested and found any sweet spots for the power/ hash

You need to replace that faulty hash board (Chain #2).
Is your warranty still valid?

Hiya I guessing the warranty is 12 months so this miner is just over that. I see on eBay boards for about £60. So I'll just get one of those I think. Looks simple enough to replace. But in your experience once they fail like this they're not fixable?

If you know how to do board level repairs, you can try. But I guess you don't necessarily have experience and tools for that.
You also might want to think if it makes sense to buy a new hash board. 60GBP is a high price if you think about how unefficient this V9 miner is.

Yes I hear ya. Woulndt bother at all with the V9s if I didn't get free elec for them.

Oh! I did not even know about These! Thank you. I have a couple of my own rasp Pi. So presumably if I do some research I can use my own rather than buy theirs. Brilliant. Thanks a lot.
Just ordered a couple. They are good value. I reckon 6 months for ROI. Just need to dig out the old raspberry Pi's now

Sounds good. Should be a better choice than a new V9 hash board.

anyone else having issue with no best share showing and no nonce values on the GUI of the V9's I have a load of then and none ever show the best share I have updated them with the firmware from bitmain site but still nothing.

I have an unusual situation. Free power with rent as a deal with the landlord. So I picked up a T9+ but the controller quit from a mishap with oil cooling that turned conductive. (no leds, no response on ipscan, intermittent, then dead). However, my friend has a new in box V9. Is it possible to reflash a V9 board to utilize the 3 good hash boards I have on the T9+ ? I probed the T9+ board to discover that it's not a complete circuit anymore near the cpu itself. Only partially some of the circuits are live on a logic probe.
So the question is, these controller boards have six sockets for hash boards, how do they know which chips are on them, programmed beforehand? If so, then one would assume that you can flash the board for the correct hash boards attached. I'm more familiar with BIOS updates on motherboards from Intel, gpus, and not sure about the architecture driving these hash boards. ?
