Topic: A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping - page 23. (Read 122577 times)

Inno makes many more products aside from our miners.  They should be willing to support these devices even if sales go south.  Whether or not they will remains to be seen.

Sadly they need to drop the price down in line with what Bitmain is charging for the S9 if they want to see sales continue.

Kinda what I said a few days ago -- However, this is a double edge sword. Part of me is now worried that if LTC doesn't recover and people stop buying the A4 that Inno might be in danger of not having the funding needed to provide us the support and things we need to fix our B1/B2 miners.

Yes, LTC now at 3.63 and falling I won't be buying any more A4's at this price.  The price needs to come down.  Diff increase and lower LTC price is just too much for me to justify this price point and it does not appear to be improving any time soon.

Heh. Under warranty they should be giving customers vouchers you would get paid from at
Your rates. They could then monitor each fix at set price. So much for their warranty on plus minus
Within 10% hash rate and a working unit.

Moot now not worth getting at 1900 usd with shipping as with ltc it is at 3.86 usd at 280mh if you could get
Such it is 141.80 a month at 11c kWh elec lol

Edit: above price mistyped. I meant ltc was at $3.68 usd above.

1. Unplug and Remove Fan
2. Remove the 2 screws that hold the cards into the chassis.
3. Slide out cards, and remove stickers covering contacts on each board (Batch 2 cards)
4. Move the mode selector switch on the Jig towards the Mini Downloader into the Up/Download position (see photos)
5. Plug both USB cables into the jig (they're powered from any standard USB socket). Both lights (red and blue) on the Mini Downloader should be flashing.
6. Place card (with heatsink on) onto the jig.
7. Lower the contacts onto the card using the handle
8. Push the button on the Mini Downloader. The Red light will flash a few times and then the Blue light locks on. This indicates that the firmware download was successful.
9. Flip the mode selector switch into the Down/Decode position away from the Mini-Downloader. Watch the card's LED. It should come on in a second and will stay lit for 5-7 seconds while the jig performs some diagnostics (my assumption, not documented).
10. Once the LED goes off, raise the pin assembly, remove the card, flip the mode selector back into the Up/Download position, and remove the USB cables.
11. Start process again.

That's it. The reflash process takes about 30 seconds per card. I struck a couple of mine where the LED began flashing like crazy at step 7, or step 9, but resetting the card in the jig and/or performing the process again from the start sorted it.

If you can get a Jig, anyone who can handle a screwdriver can do this job if you follow the documentation and keep your cool if LEDs start flashing.

Yup. At this point they seem to be thinking along the lines of sending some jigs to the US and having customers pass them around instead of swapping the MCUs. That could be one way to do it.

If I was doing reflow work, I'd charge .2 to .25 btc or so per board to swap the mcu's. Reason being:

Takes about 10 minutes to unpack, place, flux, and pre heat a board.
10 minutes to pull the MCU and cool the board down
10 minutes to place the new chip, heat up, and reflow the new component
30 minutes to hook it up and test it to make sure it works then re-box it.

So, hour a board. At .3btc per hour (my hourly billing rate for reflow work) that's a bit of a bargain but I can probably do two boards in parallel on the IR preheater.

For that I would also need a few 1.0 boards from Inno plus a bag of chips to get the process documented and down to a science.

What might make sense is to have the big mining shops get the jigs and reflash their dozens of boards, but the one-two offs send it over here to be swapped. Or they can send me a jig and I'll do it for .1btc per board to cover the time for overhead.

Just sent off an e-mail myself to Chloe asking if I can get a Jig here in the USA

anyone knows how to set the #xnsub settings on the A4s if mining on stratum+tcp://scrypt.usa.nicehash.com:3333 ?

It was mentioned further back in the thread that they would pay lightfoot to perform upgrades in the US.  But it didn't pertain to me so I haven't followed how that developed.

SO it looks like we have a jig in NZ and now one on the way to Canada.. We need someone from the USA now that knows how to perform this fix. I already put in a email to Chloe about the fix but have not herd back.. We need others from the USA to contact Chloe about getting one for the States.. I will take delivery of it but would do no good as I dont know how to do the flash fix.. Who in the USA can do this fix? Maybe its not that hard? If not I will take one here and do it

Please take some pix and instructions of how to use the jig.
I haven't heard anything about it yet other than there is some kind of jig.
I did hear that Chloe was looking for someone in the US to be a clearing house for the fix, but nothing beyond that.

Personally I know they are shipping a jig to perform the upgrades to a group of us in Canada.  And we are suppose to pass it along to anyone we know also in Canada needing the upgrade.  I am not sure about the states and the group buy but all it takes is an email to them.

Where dd you hear this about shipping miners? I am ready to do something but need to know what to do

Maybe we should start a list of how many B1 and B2 miners need re-flashing and where you live so we have a better idea how to move forward. Any word from Chloe? This should not be taking so long they need to make this right

Thanks for that link. I have tried looking for the boards separately but not had any luck.
I have 2 of the 2880W PSU's running my A4's with no problems...
However, because of the need for power cycling the A4 rigs, I have been thinking about getting some of the HP 1200W server PSU's and a breakout board for them so that I can individually cycle a single A4 rather than the PSU attached to 2.5 A4s...
Im also considering bying additional PI controllers so I can run smaller rigs, which makes the power cycling easier and less of an impact.

User - Finsky - https://bitcointalksearch.org/topic/ibm-2880w-psubreakout-boards-new-package-deals-for-t9s9-a7-966135 on this forum sells these setups from J4bberwock -- I've purchased from him and it works great.

Do a ebay search for "2880w". There are a bunch of these out there for less than $100.
As they supply 2880w, they can host up to 2.5 miners (5 cubes).
Many come with the adapter cards to get a bunch of PCI power connectors.

Sounds like they are going to have us ship our miners to be flashed.  I haven't heard any additional details yet.

Anyone hear any details about the replacement chips yet?
