KNC really needs to ship a bonus Titan to 1 batch buyers. If not then at least an additional module.

Strategy: Failover or Load balance? With Failover I don't get a connection with Nicehash.
load balancing doesn't work
Really? 2 cubes work (20-25% rejects) with load balancing and Nicehash (the other 2 cubes don't get recognized).
With failover I don't get a connection to Nicehash.
KNC have admitted on their forum that load balancing is broken. If load balancing worked it would be very easy to refute the KNC lie that all the problems with reduced hash rate at various pools are because the pools aren't set up to handle the 'extreme power' of the Titan.
So they're not in a rush to fix load balancing right now.
I could change the settings from load balancing to failover. With load balancing I had 150 MHs for 2 cubes and 25% rejects, now with failover I have 100 MHs for 2 cubes and 33% rejects.
The one I was overclocking was soldered directly to the Titan cube using TWO high quality 6x PCI-E connections (NOT the cheap square pins with the split down the middle).
2 PCI-E 6 pin connections for 1 cube?
Try changing the voltage/speed of the others? I have some KNC gear that would act like that and required I actually raise the speed of the bum ones above stock, and in some cases lowering voltage. I've also noticed sometimes neighboring DC's if running too high, would shut down the bum ones. Almost seemed as if they were pulling current away from them.
Thanks for the tips, I'll try that. Can't raise clocks above stock, though. 300MHz is the highest selectable speed.
I found a config file in the Titan SD image that had a preconfigured max speed of 475Mhz for the Titan. To overclock the Titan edit waas.c, recompile and install.
Edit: /home/pi/knc-asic/waas/waas.c
Change this line from 300 to 475:
Code:
#define MAX_DIE_FREQ_TITAN 475
Then:
Code:
cd /home/pi/knc-asic/
make raspberry
cp waas/waas /usr/bin/
Next time you restart bfgminer the advanced page will have selectable speeds up to 475 mhz.
FYI: I had a titan cube overclocked to 400Mhz and was getting about 100Mh/s but the hashrate slipped down quickly over time (even though dcdc's were fine). Not sure why, temps were decentsand everything was working fine.
Might try again at some point.
Note if you are overlocking you had better have damn good connections at the PSU and the Titan. The one I was overclocking was soldered directly to the Titan cube using TWO high quality 6x PCI-E connections (NOT the cheap square pins with the split down the middle).

Thank's for the info!
Which settings do you have for Quota (1) and Password (x)? In the past there was something like d=0.08 instead of x for the password for GPU miners to reduce the rejects. Can't remember anymore.

Have you bothered to read any of KNC announcements?
Yeah, all of them. Every day.
"We are working around the clock to fix the problems"
"We don't know when you will receive your miner"
"If you are having problems, just disable the monitoring software"
"If you are having problems, power cycle it"
"If you are having problems, try switching cables"
"As mentioned here many times, we are working around the clock to fix all the problems"
"No we didn't really mean it when we said we would have all Titan machines shipped before the end of Q3"
"Its all the fault of the pools"
"Cricket, Cricket"
"Go away"
"Don't ask difficult questions"
"We are working around the clock (5 day week, 35 hour week) as fast as we can"
KNC is a POS company actively engaged in avoiding responsibility for the major failure called the Titan
Rufunding all the Titan customers would probably put them out of business.

Any CA batch (batch 0) customers received their bonus Neptune yet?
Have you bothered to read any of KNC announcements?
Go read them, then if you still can't find the answer come back and I will point it out to you.

Can't get 6 & 7 to start no matter what. I've tried raising voltage and lowering clock speed to no avail.

Well, that was short lived. Titan is starting to fuck up, cube 4's die 4 won't work anymore.

Safely shutdown Titan by killing power to the controller board first, then power cycling the remaining power supplies directly connected to the cubes. You can also run command "sudo shutdown now" to shutdown softly or "sudo shutdown -r now" to reboot softly. All needs to be done at bash command prompt from ssh pi@.

Can someone please tell me which Miner Settings are working ... I'm mining since 1 year with cgminer, sgminer and ccminer but I don't have a clue what's Quota
These are my current not working settings:

"quota": "stratum+tcp://stratum.nicehash.com:3333",
"user": "my-BTC-walletaddress",
"pass": "x"

HW Status says only ASIC Slot 5 and 6 are working but two other cubes should be recognized. I have 2 PSUs with 1300 watt each, both running, all cube fans running.
I've connected all 4 cubes the same way to the board, red wire on the right, if you look at the board.
One red LED (below PP10) is on, at the top board (the one with the LAN connector).
Any ideas?

How do I savely shut down the Titan with 4 cubes?

Replacing the class 4 SD card with a class 10 gives better read/write capabilities to the linux platform. I'm still having a problem with reboots though. The miner will run for a while, heat up the DC/DC on the boards and then blank any submissions, yet bfgminer stays open for a few minutes until the counters reset and start mining again. Lots of delays between submissions. The first 8 hours of mining has been sporadic at best.
Throttling all hot DC/DC cores back to 275MHz to see if the hardware is just stressed. In 1/3 of a day, I have only roi'd 1 ltc.
More details to come.
Throttling all hot DC/DC cores back to 275MHz to see if the hardware is just stressed. In 1/3 of a day, I have only roi'd 1 ltc.
More details to come. I highly recommend ditching the class 4 micro SD and purchasing a class 10 4GB to get more stability.
Does a 8GB micro SD work as well ? (That's the smallest I can get at my local store).
And is it just a matter of stopping the Titan, exchanging the SD card, and restarting it again? Or is there more to it?
Wasted space doesn't harm.
What is important is the class of the SD card (read/write speed).
Look for Class 10.
Switching to another SDcard is the same procedure like your SDcard corrupted.

Prepare your new sdcard, shut down your miner, replace sdcard and restart.
ahhh.. thank you. !
