Is there a way to specify cubes or dies to use with BFGMiner so a Titan can run multiple instances without them stepping on each other reconfiguring dies?

I've been looking for controllers to split it up but it's like finding a unicorn.

As far as I know, you can flash these for a mac pro and pull over $200 a card on ebay.
I would do it but i don't have a mac pro to test them..

Uhh, Mr. MPH, you might want to do this:

https://blog.zencash.com/mandatory-upgrade-zen-2-0-14-super-nodes/

From the above link:

--- cut ---
We are pleased to announce ZenCash 2.0.14 upgrade is now available! All node operators, exchanges, and pool operators must update from the previous version before June 28th when the current version is deprecated and will stop working (at block 332576). Please follow the instructions below.
--- cut ---

My miners have been mining "air" for the last 8 hours or so on MPH since we hit block 332576.

Letting this go on for 13 hours and counting is unacceptable to say the least. Maybe they will compensate..

Bought 1 Titan. And in Q3 I find myself with... NOTHING.

Please sign up for the class action if you were a Titan customer:

I'm skeptical that this attorney is ready for something like this. As far as I can find, she's only been practicing for 2 years and it's mostly traffic court. KNC with our millions may eat her alive.

KNC has been assuring readers of its forum that the bad experiences of Titan owners who conribute to the KNC forum are not typical customer experiences and that impressions of unreliability and faulty behavior of the Titan gained from reading the KNC forum are a result of sampling error, ie: most posters on the KNC support forums are going to be people having problems.

Fair comment. However KNC are unable or unwilling to produce statements or affidavits from happy Titan customers.

So, lets take a survey.

Are there any Titan customers here who have received a fully functional and reliable miner which continues to operate reliably and can mine any scrypt coin at 300+ Mhs without baby sitting, firmware reloads, SD card reflashing, or significant bfgminer errors ?






Figured I'd chime in here. After making a nice profit with a Jupiter split with a friend we both decided to buy Titans immediately once they were available.

Titan 1 (mine):
running on fw 1.02 currently getting 300mh/s on wemineltc. Only pool that will achieve 300mh/s that I have tried. Original SD card is corrupt. I bought 2 extra class 10's and a spare Pi just in case. (more money down the Titan drain)
fw 1.03 or 1.04 results in dead dies within 10 minutes of running. It's always ASIC 0. Moving cubes around doesn't help. No matter what cube is on ASIC 0 the dc/dc's disappear or go dead. Fw tries to restart dies but never succeeds and just loops messages in bfgminer every couple of minutes.
So currently stuck mining LTC (which i didn't want to do) and probably stuck on 1.02 if future fw doesn't solve the dead die problems.

Titan 2 (friends)
Was running 300mh/s on wemineltc before the SD card got corrupt. He bought a new one and reflashed now it's about 220mhs on 1.02 on wemineltc. Not sure what the issue is as he hasn't had time to explain or troubleshoot but I do know all cubes are running at 300mhz. Probably dead dies but I'll check that next time I have a chance to look myself.

Although it seems like I'm one of the lucky ones, overall we are not happy with giving so much of our profits back to KNC for a product that isn't even close to what was advertised when we paid for it.

Re: [WTS] 5x Gridseeds, 12V 30A PSU, LightningASIC controller and all cables

You can get 10 Gridseeds with PSU and cables on E-Bay right now for about $110.
Gridseeds are barely cost effective to ship at this point. Sad



Exactly. I gave him an offer that would have covered shipping plus extra. His reply was LOL.

Told him if he wants anything close to what he's asking he is better off to go to eBay with it because no one here is going to buy for his price.

$35 offer was funny, you gotta admit..

I'll take $100 for the lot.
$10 for the hub, $10 for the tp-link, $10 for the PSU, $10 a gridseed, $10 for the cables. $10 shipping anywhere in the US. Does that not sound fair?

Looking to sell my last 5 remaining gridseeds.
It comes with the 12V 30A Power Supply from LightningASIC, 5x USB Cables and 5x Spliced barrel connectors that work with the supplied PSU.
Also including the LightningASIC controller with the newest firmware. https://bitcointalk.org/index.php?topic=554542.0

Looking for around $150 but I will take offers.
Shipping out of NYC using USPS. Pickup is even better.
Escrow allowed, paid by buyer.
BTC preferred.
Please PM offers or post any questions/concerns.

Did you close this deal yet?

I would offer a Scrypt G Blade 5.2 MHash miner for a Jupiter.

Brand new ... I don't even have it yet. It should be here tomorrow.

Message me.

I'll trade for the blade, sent PM

I will also take a trade for Scrypt ASICs

Will you take 20 grid seeds accessories included  6 MH/s plus in total?

Yes, I will make that trade with you. How would we go about it? Escrow coins maybe?
