I am eventually gonna send you some btc but for right now I am unsure due to the fact that even you you fixed the firmware to ignore DEAD dies and your other
 adv page and I also like the temp tweaks......options) ie you will get some btc if even if i never use your mods just for the pleasure of watching you try and succeed

but anyway am still stalling installing it for now (away from home a lot over time this month)

my question is how do you handle the soft asic resets where it comes up 1a NONCE received whatever the msg is ..and eventually it fixes its self promptly after
maybe saying the same message in 4 lines like 1a 1b 4c 2d or whatever?

I already have 2 dead dies on a cube each on the 2 port controller on the 2nd Titan ....so constant reboot for this sorta soft asic issue is not needed

anyway anyone have these pop up and the firmware shrugs it off without issue? just kinda staying behind the pack of folk here  in that I will use this 2 cube unit vs the
6 cube other unit to test and with these issues as my testing of such but the two cube unit has these issues

1) 1 die dead and set to off on each cube

2) my temps are high on the vrms can go above 85c seen as high as 90c and it still hashes (one hot cube)

3) the soft asic resets or whatever they are called above ..how does your firmware handle such

lots of dorky stuff and constant reboots are probably not too good if issues using this as the test unit of the firmware

so braver folk then me anything above an issue or is all golden? or don't ya know quite yet?

If i get a weekend off and can watch the unit I may toss this up just to see what goes boom but maybe others know more already?

(we also serve who quiver in fear with the woman folk in the rear during the battle ..much nicer and more cozy) Smiley




Just try it out man, Im not sure what reboot issues ur experiencing, is this with my firmware? If not then no idea what u speak of. I dealt w/ the reboot issues when dies are flagged to off manually.
My firmware really doesnt do anything w/ soft resets.

UPDATE:
New release v.92

Ability to set DCDC temp threshold on/off & temperature via webgui.

NOTE: due to having extremely minimalistic webpage coding skills... the values shown on page DO NOT reflect current settings.
Its ok to update DCDC settings as many times as needed, the BFGminer is not restarted or interrupted.

Need to refresh ur advanced settings page for it to show =)

Thank you Ill send more BTC in the next day or two. Guys if you want this quality of work to continue, youll have to send some BTC also, nobody works for free.

Vegas

Thanks man!

Im implimenting webgui control now =)

That was something we were considering , but after looking everything over, its a really bad idea. Im sure Tarkin will remove that option in the next release.

@GenTarkin. The biggest threat to these miners is the temp of the VRM. I think the critical temp of the vrm is around 85C. Can you put a switch in that will shut down the die @85C , that we can choose to have this active or not, or even better have a drop down to choose the shutoff temp, and a switch to activate or not.  I can send more btc if you can do this. This prevents permanent damage to the VRM, thats what overheats, NOT the processors or dies.

Vegas

UPDATE: have a working VRM checker. It basically disables the die whos VRM is over 85. It simply turns it to OFF in webgui and restarts bfgminer. The die can of course be turned back on by selecting a freqency in webgui and reapplying settings.
Controlling it via webgui is probably not gonna be an option at least for now. I have no idea how that portion of the webgui code works lol.
Will post when its ready for download =)

The VRMs enter thermal shutdown at 120C to protect themselves, anything over about 105C is getting sketchy but under that things will make it..
Are you sure? Well, people cast in what they want the thermal trigger at and Ill change it to that. For now its 85C

Note donations would be greatly appreciated =)
I still have yet to be paid in full for the .5btc bounty =/

Hrm.... that may be way beyond me unless theres an example already in the code that I can modify =) but Ill look into it.

Sadly the only limitation is not within the cables themselves. Its within the PCIE 6pin connector as well, its actually rated up to like a max of 23A current. We run these things really close to that limit ..... 24/7
649  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 07, 2015, 05:38:57 PM
Why to used that Huh.

My firmware is not an upgrade firmware its a clean flash. You have to overwrite ur SD card.
650  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 07, 2015, 04:28:54 PM
I can not install it at my Titan

I do not know why

Does anyone install

Success the firmware?


I downloaded but firmware can not install it

You have to use win32diskimgr or w/e it is....
Given ur issues downloading it Im willing to bet its corrupted somehow.
651  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 07, 2015, 02:42:55 PM
I had no problem downloading the image. Haven't tried it yet though since my rig got rented while it was downloading.

Where do u rent it out at? How reliable are the renters, as in how many actually set vardiff correctly and dont cause the titan to freak out? Im curious, seems like renting is moot now =/
652  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 11:19:53 PM
Which is the password

Huh? my github states what the current passwords / logins are for the image..
653  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 10:34:19 PM
Added BFGminer version # to my github .. vegas =)

Changing passwords will be a tad harder. But will let ya know.
654  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 08:19:20 PM
Some small things Gen. Thanks for the version #'s , this helps me remember that Im current with your version. Also on the next release can we change the login and password to default: admin/admin?
Also could you be as detailed as possible about the changes such as the BFGminer Version # included on the github?

Thanks

Vegas



Sure can =), at this point I see no further changes needed tho but will update as needed =)
655  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 05:16:22 PM
Thanks for the tip Prelude =)

Heres link to the latest release.
Includes fix for manually set OFF dies, also includes latest BFGminer

656  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 04:41:28 PM
I will continue to experiment w/ die drop handling. I read another way that may be more effecient. I will update if thats possible.

What I've noticed with a couple of my temperamental dies, is that it will spit out errors about invalid nonce, then it will give a message saying the die was successfully configured and it will go back to work as normal.

So that appears to be cycling an individual die, if you want me to grab the exact messages to track down where in the code it's doing it let me know and i'll grab a screenshot next time I see it.


Thats cool it works for you =) ... for many the "soft" die resets you speak of dont work. My Titan included. So the "hard" reset fix I came up w/ works 100% of the time w/o me having to baby the Titan.
657  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 02:57:18 PM
Ill upload a new image today guys. I would really appreciate any tips. Worked hard on this.

Update on 350mhz: its not really worth it at this point. Ive looked at the way they clocked up neptune and I can say the eeprom on our devices seems completely different than neptune / jupiter. So using the same registers to set clock speed is a huge unknown to me at this point and I dont wanna risk killing any cubes. Id be willing to experiment on a cube if someone was willing to ship, also Padrino said he may be able to as well, but there are no gaurunteed results.
Also, as previously pointed out the VRM's are at their rated max. Running them beyond their rated max but under their OCP point is still risky, putting more stress on them is not a good idea. Especially 24/7, they will probably just pop sooner than later in such conditions, unless they were cooled really well.

What my firmware image will includin is all fixes Ive implimented to date for "soft" dropping dies + more stats in webgui + updated bfgminer(updated to latest).
I will continue to experiment w/ die drop handling. I read another way that may be more effecient. I will update if thats possible.

Once again donation addy is:
1Px71mWNQNKW19xuARqrmnbcem1dXqJ3At

The .5 bounty still has yet to fully be paid on, .3365 has been delivered thus far =)

Ill be uploading new image soon to github. For those of you who have my btsync share, its already updated in that, just wait for it to redownload.
658  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 04:52:41 AM
I read on one of the threads this:

I have removed the aluminum plate, so now I can see the Ericsson VRM's..... this is bad: they are the BMR4641002 (max 40A) instead of the BMR4641008 (max 50A).  :mad: ...... no OC possible !

The 1002 has a OverCurrentProtection of 48A and looking to my Advanced-page: nearly all the VRMs are already around 46-47A (and this is KnC's default setting).
They should have used the 1008 instead, which has 50A and an OCP of 62A.

So my question is how difficult would it be to replace the VRM on the board with BMR4641008 (max 50A)? Is this something that can be done with a soldering iron , or does it require a special machine like a reball machine? Is it JUST the top chip or the entire board underneath that VRM chip too?

Vegas
 

Holy fuck KNC is cheap as all fucking shit! Yeah, you wouldnt want a 350mhz setting even if you had it. I wonder if this is why random dies drop... Constantly running over spec, I bet these VRM's could definitely use little heatsinks on them.
The question is what is the limit of the rest of the components in the VRM? sure you could swap out the main one but.... w/o knowledge or ratings of the other little ones... they could easily blow.
659  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 02:02:54 AM
Question if anyone knows :

Im going to remove the stickers and put thermal grease on top of that large black chip. Is this safe to put conductive grease there? How about the 2 smaller chips? I also have epoxy thermal grease I will use to bond the copper to the vrm chips, but I am hesitant to put any conductive material on top of those chips. It seems like the larger chips with the yellow sticker are ceramic, but Im not 100% sure. Any advice guys?

I found this pic on the net with the large processor cap removed and you can clearly see the dies underneath. Kncminer said 2 cores per die. So that makes sense.

Whenever I put heatsinks on stuff that was questionable conductivity , I just used stickers thermal pads . Always worked but may have just been lucky lol
Ive had heatsinks touching one another that were on seperate VRM components on other devices like gridseed blades and there was never a short =)


Also, on another subject, for those of you who have dies that are no longer working, like permanently damaged but the board is not physically damaged, have any of you tried to reflow the boards?
They may have just stopped working from cold solder joints. I have brought back to life several laptop mobos w/ a good heat gun , Ive also done video cards in the oven w/ some success =)
Id say its worth a shot.
660  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: August 06, 2015, 12:21:07 AM
I found these pics of the board: I think this is from a neptune, but it looks identical to the titan.






Really?! wow so the dies are protected then. They are underneath the heatspreader in the center there. Thats where the heatsink mounts directly.
For some reason I thought the dies would be bare like hashfast cards =P, guess not.
Anyways the VRM's are those smallish lifted boards around the ASIC

If you put ur finger on the yellow sticker and on the 2 little square things in front of it(that seem to have a metal center)
They will feel really hot when unit is running. Those are the VRM's for sure, putting tiny heatsinks on them may help cool them and the yellow sticker square heatsink would go well on that too =P
Theres probably other areas that could use little heatsinks. But that would be my initial guess off top of my head =)
