does anyone else have D3 blades crapping out left and right???  (even ones NOT modded)

Having problems over here. A few un-modded ones are having issues with their boards. Glad we're still in warranty for them.

v2.06 beta :: 05/01 :: test version

Download:
https://mega.nz/#!mxwhmCZb!8Xsj5c2bfvuaK_fSI2av3zrqv3dFz-w3AoSt7W-MD8U

Changes 05/01:
- more stable autotune / reset of ASIC chains (HW errors will be reset to zero after changing a board's frequency)
- ~15 to 20 seconds faster startup of the miner after changing a setting
- optimized cgminer binary size
- fixed browser caching issue when changing between stock and blissz firmware

Changes 22/12:
- reboots the D3 on high temperatures (> 85 deg PCB temp). This feature will save your unit in case your fans will fail.
- improved auto tune algorithm stability
- Increased the chip starting frequency of the autotune algorithm for higher voltages.

Changes 14/12:
- fixed auto recover from xxxx
- cleaned up kernel logging
- a bit more aggressive tuning
- tunes down faster now when too many HW errors are detected


Changes 13/12:
- Totally rewritten code base, based from latest available bitmain / cgminer sources
- ASIC's now automatically recovers from xxxxx errors without restarting (The auto reboot options are still in there in case it doesn't succeed)
- blazing fast mining status overview in the webinterface Cheesy
- as requested: the dev mining starts later now (after 5 minutes)
- as requested: dev pools status is now visible in the miner status


Important: The autotune feature is not completely finished and the startup is a bit slow now.. Therefore I need your help. So what do you need to do:

set your advanced settings the same as displayed bellow
let it run for at least 20 minutes
PM your (complete) kernel log, or if it doesn't fit, focus on the last part
By doing so I can get to a conclusion what the starting frequency of the auto tune algorithm should be.
In case you want to help more: increase the voltage a bit and do the steps above again as it will give some more information

Thank you!



Blissz, have you gotten my PM's or noted my posts? I'm having some issues, but would like to submit the kernel logs to you and the PMs have a text limit size.

I'm testing out the new beta version of the firmware, and after a day of futzing around with it and letting a couple units run overnight, I noticed something.
Awesome Miner reports a few thousand errors on the primary page (Because it logs the errors) for the units that were auto-tuned and stabilized, but the IP access page shows zero HW errors. While I watched, it had a few, and once it reached about a dozen - boom, it wiped them and they showed 0 again.
Is this a new feature, or something accidental? Knowing how many HW errors I'm getting is somewhat key to knowing if I've found the sweet spot or not for freq/voltage...

Also, there's an abnormal amount of errored out chips (X) that don't go away when the unit finishes auto-tuning, not without a reboot - and then it takes another 10~20 minutes to finish auto-tuning, which results in more X chips, to the point that I basically just let the auto-tune do its work, then go back in and manually set the chips to the frequencies that worked, and watch if it has errors or not at that point.
In essence, the auto tunes present functionality just saves me the elbow work of manually changing each chip within the frequency range (a process that honestly can take hours per unit).
But it would be nice if I could set a range of what I'm aiming for (x range of GH/s, within X range of temp) and it auto tunes both the freq and the voltage to accomplish it, on the fly.
Or even "benchmark for best settings" options and it auto tunes in depth, finds the best results at the lowest energy consumption and saves those so that even on a reboot it doesn't have to re-auto tune back to that.

A bit quiet from my side, but I have been busy on the background and I have some good news for you guys:

I managed to make the v2.0x beta a lot more stable. So hopefully I am able to have a stable 2.0x version soon. From there more features will be added for the D3.

Furthermore I bought a L3+ (mainly from the dev fee, so thank you all!) and I got some good news on that:
I was able to unlock the voltage on the L3+! Cool
As the L3+ got some headroom for overclocking a bit of overvolting can be useful for the first months. After that you probably want to undervolt it to save power as more L3's will come online. (my L3+ mines 500Mh/s @ ~680 watts from the wall now)
Please don't ask for a L3 test version yet, as it's not even close to Beta stage yet and it seems I bricked some of the chains during testing which I have to fix first.
But this is definitely a breakthrough for the L3, so there will be a first L3  beta version available within two weeks I guess.

 Shocked
This should be interesting! I'm helping a friend run their L3+'s (they have two) and we've been able to overclock them to 600~625 MH/s with basically no HW errors. If you can do the same with lower voltages, could definitely increase profitability of the L3's!
