Question...

Would anyone find it useful to have a checkbox in SYSTEM tab something to the effect of "boost rpi performance"
It would apply a mild OC to the pi that *should* work on all pi's the Titan uses.
Ive noticed w/ the rpi @ 1ghz vs stock and a few other items OC'd ... the CPU is not always pegged at 100% when Titan is mining, like stock is.

Given that blowing the RPI Cpu will result in the bridge board blowing I would say not a great idea. :-)

the CPU on the rpi can, in most cases, hit 950mhz w/o even a voltage bump. Its when people start crammin a ton of voltage at rpi's CPU that it dies.
But thats cool =) , less work for me. Ive been running pi @ 1ghz w/o issue for 3/4 a year now.

I know. But every Bridge Board I have fixed came with a Rpi that was dead shorted on the CPU. Those things are garbage for 24*7, they should have stuck with the beaglebones. So what we really should do is just port the Titan code over to the BB. Which I would do but I keep being too lame to finish it.

I don't mind the work or bitcoin, but I would prefer if people never had the problem in the first place and could mine like hell. :-)

Well I finally junked my KNC Jupiter.

Had the miner for a little over a year, almost ran for a year. Bought it second hand really cheap. Made ROI many many times over.

Had the worse W/GHS out of any miner I had in the past (1.333W/GHS).

Parted out the controller for people who needed one for their Neptune/Titans
Parted out the fans and they are cooling my 280X which had dead fans.
Parted out the PCIe extension cables for many GPU mining projects.


Everything else was junked.


Original MSRP: $5000
Current Value: $0


So sad...

Hi, i have a problem with some cubes; strangelly, they suddenly appear a message that sais "Dies flagged for bypass of health checking: 3:1 3:2 3:3 4:1 6:1" and theese dies are not hashing and i can do nothing to fix it (reboot, change the controller, change the psu, change config...). Here is summer, but i have them with a low configuration to mantain them below 70-75ºC, so i don't think it could be because it is too hot. Here is a pic:

PS: I'm using GenTarkin 1.0.3 and 1.0.4 (i tryed both)




I am worried about theese cubes...

I had exactly the same thing with GenTarkin software.
Better use  Original KNC software with the same volts.

I did this and it is no problem any more. When i  replace the memory card to GenTarkin software ,  the problem is back.

Im no expert by any means but I get the same thing every few months on my titan.  WHen this happens I normally re apply the thermal paste. So far this has solved my issue every time but I cant promise it will be the same for you.

This is happening because those particular dies are so unstable in any given point in time that multiple attempts were taken to get them hashing again through the form of soft / hard resets done by my firmware.
In short it means those dies are unstable and my firmware will no longer try to bring them back online to prevent bfgminer from constantly restarting.

The stock firmware will do the same thing repeatedly w/ no positive results - soft resets to infinity. While it doesnt cause bfgminer to restart constantly it can severely hamper mining performance.

You can attempt to lower the clocks on those dies and up the volts(which is stock already and I wouldnt recommend going any higher). Also, like AmDD stated, it may be an overheating issue of those dies and its causing them to become unstable, so reapplying therm paste may do the trick.   Theres no way to tell the actual temps of the dies on these Titans.

Also, if you want you can save the log files and email them to me via my website.
Lastly, hitting "CLEAR" will unflag those dies and next time bfgminer runs it will retest them.

Interesting.... Im going to guess you have dies that eventually stop hashing over time w/ stock firmware?

No, they are selected  cubes  which has never been a problem with hashing at default settings.

using GenTarkin software is the most effective way to run the Titans, I spent weeks on testing.

Odd ... well, unless there is some unknown bug in my firmware which triggers erroneous die resets, those cubes most likely do have some sort of issue going on.  Afterall, your cubes may be one of those that after many upon many software resets the dies come back just fine. There are a small number of Titans which act like this. I guess it could be due to faulty pool work / connection problems too.
My firmware uses the same cube/die problem detection code(die amp threshold), it just handles the situation way differently then stock firmware.
Anywho, log files would give an insight as to whats really going on.

Interesting, Ive had many pi's over the years. Not one single issue.
I know, it's odd. And I've never seen a BB that did this either.

It is *possible* that the gpio pins are being overdriven running the various spi signals to the boards and the fpga, but that sounds like a bit of a stretch. Still it's possible, I've got a total of four dead Pi's from various people who sent things in for repairs. In all cases the Pis blew out the CPU and sink a lot of current.

Fortunately fix-able.

While I don't any KNC gear, my experience with Raspberry Pi has been quite favorable. I can also say that my sum total experience involves ZERO use of the GPIO pins. Everything I have done has been USB based one way or another. My recollection is that the GPIO pins are designed for 3.3V and NOT 5V. Might that explain anything, or do I have my figures wrong?

Your figures are correct. It can only output 3V3 and can NOT accept/output 5V input.

I repeat, the GPIO pins should NOT be exposed to anything above 3V3.

I''ve decided to offer my KNC Titan for sale.

Mining is going to take a back seat while I  focus on finishing my trading engine and asset management software. PM me for details if you are looking for extra cubes or a whole system with dual EVGA 1300s. Its a good one. BTC accepted and escrow is ok.

Would be nice to sell here instead of on ebay.
