Did you try the Blissz firmare? I has helped me stabilize mine, but a lot of trial and error there (changing settings for 1 board affects all the others somehow). I'm not sure if warranty is worth it.

Yes, I finally managed to get it working. Used blissz' firmware and lowered the frequency on the board that seemed to get the most errors. It's now running at around 16 GH/s and is relatively stable. Can't imagine it's gonna last long though. It must've been damaged somehow.

ya mine are running off APW3++ 110v. will be getting 220v wiring soon.

but i also heard that sometimes its best not to have the powercords lying on the datalines going from each card to the controller, i will be trying that out.
and ya, using one card at a time.

Yeah, that sucks. It's weird how every time 3 boards are on, only one of 'em has like a shitton of errors, while the rest seem to do relatively fine with 2-3 per minute. But powering them on separately just gets them drowning in errors. No idea what could be causing this...he'd be willing to buy a new control board but if the every board is done for, I think he's just gonna have to call it.

ya same thing, well sorta, i got one card in one miner now switching between 55 and 60 asic found on reboots, and doesnt matter of freq, even at 400 same thing.
and another miner with a card, that gets hw all the time.

36 hw errors in only 1 min. yep. pcb is at 70, chips at 52-55 for temp.

i think its warranty time. only 1.5 months old.

i know they are from china, made by children but come on. (sarcasm)

My friend has a D3, the 19.3 version which suddenly (simple reboot after it had been running flawlessly for days) gives out thousand of HW errors. We powered the boards consecutively, and all of 'em appear to have the same problem, but to a different extent - as in not all of 'em are prone to the same amount of errors. This led me to believe that the control board might be the source of the problem. Alas, I tried the board from my machine, a 17.5 version that works without issues. Lo and behold, nothing changed.

The only logical explanation is that all 3 boards are damaged, in which case he's screwed. But I find it hard to believe that they all developed the same problem after a reboot. None of them are presenting the infamous xxx's, they just get pummeled with 60-80% errors. I'm at a loss here, can anyone give me an idea on how to address this? He even used a bunch of different firmware, nothing seems to help. His warranty is now void as well, so there's that. I'd appreciate any pointers, thanks.

//edit: btw, the temps at which it runs are somewhat high, but acceptable nonetheless. Around 70C.
