Antminer S1 - HUGE Amount of HW Errors?

[GunXpatriot]

Honestly, I'm not sure how long this has been going on. Perhaps a week or so? One of my Antminers has a huge amount of HW Errors.

As of the last 15 minutes, I have 42 getworks, 435 accepted, 9 rejected and 1130 HW. Also 27 Utility, 66 Discarded and 0 stale.

Antminer and Pools are reporting normal hashrate. I've been on Ghash for a month now, and suddenly this is happening. I thought maybe it was Ghash, so I went back to BTC Guild. Same thing. I documented my earnings, and it was about 1/2 of expected (from Coinwarz calculator). What would be causing all of these errors?

I've had this OC'd S1 running for months now. My electricity's cheap, so It's actually still slightly profitable to mine with the low efficiency, but that's besides the point. It's on a CX750m PSU. This seems to be a sudden thing. Does anyone know how I can fix this? Also, the Ant control panel shows all of the ASIC chips are fine, so again, I don't know what the heck could be going wrong!!

Maybe you setting to high. Try to lower your setting & check the hw.

Hardware errors are errors independant from any pool you mine. Its the miner. Either there is an issue with the asic chips or something else(heat, not enough power, settings). Try underclocking. Try a new PSU.

One of my old miners had HW errors, it was heat related.

[Amph]

could also be a defective asic, there are many reason for those error, but certainly not the pool

Alright, so I clocked down to 350mhz, which I guess was the default clock that runs about 180 GH/s. Hardware Errors are now... Absolutely Zero!

But it's strange. My pool earnings were normal before, so I'm not sure how long this has been going on for, but it doesn't seem like TOO long. Even still... What would make an ASIC suddenly crap out and start getting all sorts of errors at the same frequency it was mining at previously, and successfully?

Perhaps I could try to fine tune the frequency to a small amount of errors, but still a higher hashrate than the standard 180 GH/s. I saw one site recommend like 393, as opposed to 400mhz. Whatever, I'll figure it out by tonight, I'm sure. But damn, the sudden errors are really strange, and the chips seem to be fine.

Weird.

An ASIC is like a video card, although you you cannot see it visually, when you overclock them and run them out of scope they can artifact which is the direct result of an error caused by the chip. Sometimes more voltage can help, sometimes better cooling can help but its usually a sign of over loading or imminent failure.

I'm at 14k accepted, still completely 0 HW. Would you still call it a sign of imminent failure? It seems like it'd probably be an overloading issue... Maybe, maybe not... What alarms me, is that it was in a 82+ degree F humid room all summer, now almost no humidity, and about 72-76F normally. Maybe it'll fail soon regardless, or something... But if that's the case, I'd rather have the thing function for a while before death, rather than just burn electricity and never actually do much mining...

Perhaps I won't even bother fine tuning the frequency and I'll just leave it as it. Not 100% sure yet. I'll just wait until I get the new equipment in, then I'll decide...

Also, I notice the unity is staying at 50 Celscius on both blades, regardless of over/underclocking. Maybe it just maintains that typical temperature...



EDIT: I just had a stupid theory. I now have it in a power strip with my christmas tree and lights on the wall... Stupid, but I couldn't connect the change in performance to anything else!
