Exactly. Plus this tonight... melting Titan PSU power connectors.
Thieves.
And they killed their message forum so I can't even ask others if they've had similar issues after updating to 2.00 Titan firmware.
http://imgur.com/tvyjtzHit seems that the power consumption of the Titans that where delivered with a bunch of bad cores is not constant.
my HPC antec 1300 keeps randomly shutting down, maybe thats what has prevented my power connectors from burning, but it is clearly a defective production since the pci-e connectors are not designed for so much power, they violate all IEEE standards.
and yes Sam and other at KNC are thieves, they lied to us and took our money for promises not kept, and most importantly broke the law.
I'm sure you know this but just in case from above post you are using TWO UPS power supplies with 4 y cables supplied (2 PSU leads to 1 cube) correct? Can't tell from the above post...if is just the one PSU (i know unlikely this is the case but just in case you only have 1 psu) that is the symptom when you try to run the works on 1 PSU.
Myself I run 2 corsair 1200i PSU's on 2 cubes (orig) now 3 cubes per PSU with no problems.
anyway disregard if the above is not the issue .....it just reads like you only have 1 psu and no y connectors too boot (You really really need the y connectors)
as to the bad die issue as an example ..my orig titan i have 2 bad dies (1 per 2 cubes) and got 306mh.....with a 2nd Titan I just got I am gettting (after them working themselves up to it for a week ) as of 3 hrs ago EXACTLY 650mh....on v2.00 and still 2 dead dies (1 each on 2 cubes) ....I almost took 2.00 off in that it was slower then 1.97 the first couple days but it seems after running a week it has gained me around 1mh or so..anyway..my experiences.
