What sort of power draw are you guys getting? It's been reported near 1600 watts at the wall on the KNC forums. That's double what we were initially told. Can any one else confirm this?

well if true it is hardly surprising since they recommend "two 850w power supplies per Titan" which is weird for they stated 1100 watts per Titan
they have no stable firmware...there first patch to that firmware has done 'zilch' i've heard to help
..the tech support/help page manual looks like a debug DIY kit and they can't even point out
what BRANDS work well with the Titan of particular power supplies etc

guess virtual mining on the cloud is where it is at..with no refunds the message is "shut up and eat it suckers!"

i got some cables burnt due to KNC neptune - you guys had it ?

main reason I'm scrambling to get the extra y cables from www.shakmods.com ...so IF or WHEN I have such a burn out problem ..it hopefully will only burn
out the Y connector part leaving at least the Titan plug clear from damage...

whoopie...I have a NO ROI Titan DIY kit.....

when using only 3 titan modules, the miner is stable
but with 4 modules the miner isn't stable.

it's seems that the cpu load is very high : ~ 70-80% (4 modules)
30-40% when 3 modules.

Psu 1 860i 2 titan cubes draw at 90mhs 612watt at 120v after 12 hrs.
Psu 2 1200i other two titan cubes draw at 90mhs 612 to 670watt at 120v after 12hrs

Firmware 1.02 litecoinpool.org and bfgminer stalls out once difficulty gets to 10+. Then restarts.

I would say that as far as speed the software had adjusted to the units target operating voltages.

However because of the constant restarts the full potential is not attainable. At least for now.

Cgminer may be an option?

I may have missed this but are you like everyone else and multipools don't seem to work with the Titan (just curious)

did you check is it always the SAME MODULE or any 3 work better?

are you using the 2 power suppies 850 or above recommended? hell if you have a 3rd power supply run it 2/1/1 to break it up for all 3

and check the cables I guess they are misleading


power supplie(s) you are currently using?

all I have no flames if you did all this ...just trying to help from personal self-interest (ie hell my NO ROI Titan goal now is 1/2 ROI not counting electricity

and that my be a lofty goal in itself!

Titan owners - I have a small request for you. I hear that Titans are having issues with some firmwares, therefore I would just like to ask some of you if you could point one of your Titans to our stratum (stratum.nicehash.com or stratum.westhash.com - https://www.nicehash.com/?p=gstarted#seller) for like 10 or 15 minutes and see if your Titan can actually reach full speed (as reported on Titan and as reported on our website)? We are using some stratum extensions I would like to see if KnC integrated them into their firmware ... thanks!

i found some of those controller were fucked, am i able to connect more than 4 cubes to other controller? so i dont have to waste some hash

Anyone is experiencing the restarting issue getting worse?

Yesterday I had restarts every 2-3 minutes avgr. in ~200mhz for a Titan over a couple of hours.

Today its not even running 10 sec. before restarting avgr. in ~50mhz for a Titan. On every pool I try. This is also independent from the count of Cubes connected?

are you sure all cubes are working?



Some tips for ppl who is setting up titan

1) ribbon cables got two side, they are not the same
2) sometimes the pcie slot might be fucked up, make sure to try every single spot on the controller
3) don't forget update the firmware to 1.02
4) you are able to use more than one psu to power them ( i am using 2-3 psu for one titan)
5) firmware is kinda unstable atm, using auto-switch pool might cause a 40% drop of hash ( not sure yet, but i am fine with WeMinerLtc )

Yeah - I saw your hints earlier and tried almost everything.

1) Cables are plugged in in the correct direction
2) All slots seem to work, I hashed >300mhz yesterday for a couple of hours (with reboots every 2-3minutes)
3) Firmware didnt correct the restarting issuw
4) I use 2x evga 750W, Power draw @Wall ~1300W
5) I tried every pool, so far only the pure litecoin pools work

Thing is - I didnt change anything since yesterday - but now BFGMiner is restarting every 10 sec.... (----> which leads to an average hashrate of ~50mhz for the whole Titan)

not sure if this matters with your power supply but are you using Y adapters?

[de_ixie]

No - I use the standard cables - was not prepared for additional cables. This may be the issue. Dunno - Thing is... yesterday it worked. Today not and nothing has changed in the setup...

Are they overheat or something?

Cables seem ok, Asic temp never reaches >50C (due to BFG Miner shutdown after few sec)

Dunno whats wrong - even if I just plug in one cube with 50mhz BFGMiners restarts after 10 sec - lets hope for a quick firmware update. Right now I need to shut down the Titan - not worth running it

Looks you have one or maybe two faulty Cubes.

With my Titan, I have done more than 50 tests (deductive replacing one piece of the system with another {cables, PSUs, connectors, cubes}) and now I'm sure I have one Cube which is responsible for all the BFGminer dumps every few minutes.  If I only connect the 3 OK cubes, then I have no dumps at all (have ran it 5 hours). But replacing one of the 3 with the faulty one, or adding the faulty one to get a 4 cube system, results in dumping very frequently.

I also see this error in BFGminer if the faulty is connected:
"Fault to set work state (10)"  {hundreds of those error prints}.
This error isn't present if I work with the 3 OK cubes.

Monday I will ask a RMA for that wrong cube.

Thats a good hint - I tried a few more combinations - I am running now stable on 3 cubes with around 230mhz for ~30min without BFGMiner reset

Edit: Can confirm, one cube is causing all the trouble

Don't KNC test these before they ship them ?

This is turning out to be an unmitigated disaster.
