KnCMiner Titan hardware issues

[digicoin]

Hi all,

I got my Titan (not the Mini one) few days ago. However, I became very disappointed very soon because

+ Titan hardware is not good: too hot, irrelevant equipped cables which can cause fire easily I think
+ Titan can not run with full cores. In theory, it should run with 2200+ cores. However, in fact it runs with ~1700 cores only
+ HR is much lower than what KnC promises (300MH/s): 170 MH/s - 220 MH/s on average
+ Miners are very unstable. The worker seems to die unexpectedly very frequently
+ Buggy and not tested firmware

Lot of people on KnC forum have the same issue

It looks like no issue can be solved with the support from Kurt.

My questions are:

+ What is your experience with your Titan?
+ How should I do when my hardware is unstable? Send it back of warranty?

You can mine it for a few days to earn some LTC then send it back if it is allowed by sales terms and conditions.

Same problem.  Spent two days staring at terminals and probably a dozen different errors. 

failed to set work state!

KNC totally forked us where the sun dont shine..

Considering all the delays this sucks big time.
On the pro side, I suppose this means they don't use them for their internal mining? Of course not! They probably have better builds for internal use!

One of my cubes seems to be dead

Don't feel bad if only one of dies is dead and you are left out.

Apparently over time other dies start dying off.

I have three dies that are increasingly failing now, along with the one die has been dead since the unit arrived.

KnC are real bastards for designing then shipping a broken product and then not allowing cross or early RMA shipment.
