It is clear now why KNC didn't ship a 5 cube Titan ...

But they are mining for themself with no problem i bet.

Guess Titan is over clocked, according to reply from other people, it looks like 225mh is the best frequency for Titan cubes, could be some yield issue on the chip, so hashing drop suddenly is the sign.

Guess firmware can't improvement too much of hashing power, could be a flaw they didnt detect under tap out Titan chip, so hope this is not the root cause of Titan, otherwise we all screwed in the end.

well if it is 225 mh is tops kinda thing they may compensate imho...if it is just a flaky frankenjupiter DIY kit kinda 300mh problems from KNC's point of view we will eat it all imho

at this point I don't know which if any would be worse? the same?

this looks like the death of even KNC's fantasy of scrypt-N unless they are delusional (lets see rich as hell in 1 year..power mad...naw)

Can anyone provide me with a Titan SD card image? Preferably with 1.01 firmware.
(Made after a factory settings reset or at least with known password used, or else it'll be of no use.)
It looks like my device needs card reflashing, but there is no card image at KnCMiner pages.
An image can be created with e.g. Win32DiskImager.

4 TITANS  : two on 330mhs and two on 220mhs
 
That's two 220mhs actually running fine, but they just keep restart makes a avg hash 220hash shown on pool

Raspberry pi performance should not be the issue, since Bitfury made miners with hundreds of gigahashes using raspberry controller. Software can be causing low performance though.
Raspberry Pi is just barely powerful enough to run a full bank of Bitfury cards. And bitfury's design is as simple as it gets. IIRC connecting to an active miner for monitoring was enough to cause minor performance issues. Raspberry Pi is also known for corrupting it's SD card very quickly. So in every way it's a very poor choice for a controller.

Agree.  It better for budget man on simple system.

watching the BFG log, I found :

Quote

 [2014-09-28 20:07:51] Stratum from pool 0 detected new block
 [2014-09-28 20:07:53] KNC 0: Flushing stale works (New work)
 [2014-09-28 20:07:55] KNC 1: Flushing stale works (New work)

 [2014-09-28 20:07:58] KNC 3: Flushing stale works (New work)


The last asic is hashing 7 seconds bad data cause he don't know fast enought the new block

and looking at the speed, confirm that :

Quote
KNC 0:       | 75.44/72.79/72.22Mh/s | A: 61 R:1+0(1.6%) HW:20/1.0%
 KNC 1:       | 66.69/65.84/65.11Mh/s | A: 51 R:1+0(1.9%) HW:39/2.1%
 KNC 2:       | 67.52/63.71/60.76Mh/s | A: 54 R:3+0(5.3%) HW: 6/.33%
 KNC 3:       | 59.50/59.40/58.27Mh/s | A: 65 R:2+0(3.0%) HW:13/.77%

.... mining fast coin => you will loose a lot of hashrate.

You can just mine coin like litecoin or feathercoin

this explain why the Titan doesn't work well on multipool

This has been true for every piece of KNC Hardware.

Whereas everything else I own handles blocks changes without missing a beat, KNC hardware slows to a crawl for a good 10 seconds every time there is a new block or a request for a work restart.

Not sure what they've done to cause this, why it's never been looked at, and why nothing else does the same, but it's been like this since the jupiter.

Titans put a hell of a lot more stress on the CPU than old Bitfury rigs. BBB's are the way to go for more powerful miners.

Also be sure to have a good SD card. My Bitfury rigs had constant corruption problems with the crappy SD cards that Bitfury supplied. Once I replaced them with high quality cards, my problems went away.

my opinion since last year is they are causing intentional trouble for competitors.

lying about dangerous factors and scrimping pennies at every turn.


it seesm the meeting they all attended was to share the worst traits of each company among them all.

'lets all be as shit as possible and act all nonchalant about it when out investduhs start complaining'

then when the talented among us begin fixing the problems, their 'engineers' slowly start churning out solutions - as if by osmosis.

well for those of you with problems with bfgminer restarting and cubes...there is something I read about the Titan working well on the

liteguardianpool pool and that pool having an asic ready port on it you can toggle...and someone with a Titan said they used it and it works to solve the problem

no idea what thread it was obscure

anyway that and his titan was pulling 1550? w at the wall and he is uing 1300w power supplies

so with that over kill he managed to get 300mh out of his cubes with that and other tricks

here is the link just found it

https://litecointalk.org/index.php?topic=22290.msg0#new


anyway hope this helps you all ..my Titan is not here yet....expect to hear me howl as well on here soon

(all frigging rocket science on here I can barely put an Ikeda Swedish end table together and am expected to put a damn Swedish DIY Titan together.
This is gonna drive me nuts!)

Looks like the Titan miner firmware is pretty much the same at the Neptune. My guess would be if someone goes into Advanced they should see what the power consumption is. On my Neppy at 475Mhz its consuming 1450W so it says but I know its consumes about 1450~1600W. If I stick on a single 15AMP circuit the breaker goes, but everything is good on two 15AMP circuits.

No not true...  I work with liteguardian-pool for days already.  And yes it is the best pool, but it doesn't solve the stop/restarting problem at all.  Only 2 of my cubes work well.

Its looking more and more like KNC have halted Titan shipments until they can get all the problems with the product fixed.
