Whatever floats your boat, as long as you enjoy doing whatever it is you do.

Not that one exactly, but very close.

So you don't believe that you're dead when you die? You think you're still alive in a "spiritual world"? So basically we're immortal and live forever? Or do you think we eventually die in the "spiritual world"? 

Yes. We only live once. No such thing as reincarnation, and religion is bullshit.

Make the most of your extremely limited time.

Yep, with the latest S4 firmware all is well with p2pool. I don't have an S2, but it apparently works properly with p2pool as well with the latest firmware.

The S4 is also easily overclocked to 2.25~2.3TH/s, making the $800 price even sweeter.

The reward for the block finder is 0.5%? I could've sworn I had read 5%. 0.5% does make more sense, though.

How stupid.

Just emailed them too. Thought dealing with Yoshi was a step above info@bitmaintech.com.

Thanks dogie.

Yeah, the guy I spoke with had a Spanish accent too. He didn't refer me to Yoshi, but was supposed to ask a supervisor how to proceed and then get back to me. Still hasn't gotten back to me yet.  I've spoken to Yoshi, but he seems to answer one out of every 4 emails and only once a week. Really discouraging stuff.

Out of 5 S4s, 1 batch 1 and 4 batch 2, I've had a few problems.

My first, B1, had a faulty PSU and burned out on me. Bitmain was quick enough to get me the replacement PSU, but I'm still waiting on the promised compensation for the downtime. Others have been compensated, so what's going on bitmain?? Are you playing favorites? That unit also needs to be powered down and back up every 2 days or so, because a hash board dies out and the hash rate drops by a quarter.

With batch 2, I have the above mentioned problem of 2 dead hash boards in 1 unit, and 2 other units that need to be powered down and back up every 2 days because a hash board dies every 2 days or so, dropping the hashrate by a quarter on each.

I can deal with the other problems for now, but I will eventually try and get proper working hardware. Shouldn't be too hard to get a few replacement hash boards shipped out that I can replace myself, right bitmain?? What really needs to be taken care of right now, is my half broken S4. I should also be compensated for half of what the machine should have mined since I received it.

What's wrong with your unit, macgyver? I'm also in Canada. I did call their USA number, and talked to someone who wouldn't give me his name. Told me to call him "Z".   He was supposed to call me back or email me last week, but not a peep from him either. I'm starting to think I'm going to have to book a flight to China if I want some service. KNC is easier to communicate and deal with for fucks sake.

Thanks, but yeah, I've tried everything possible. Even switched data cables from another known working S4. There's absolutely nothing to do with this unit, 2 out of 4 hash boards are broken. I wish bitmain would be able to communicate better, it's their only issue. I wanted to order another 5 S4s, but if I can't get service from them when they send me broken hardware I'm afraid I'll have to take my business to spoondoolies.

Make this right for me, bitmain. I want to remain a customer.

Can someone from bitmain please provide me with support?? I've contacted everyone I can, and I'm still not getting any help. I have an S4 that needs to be RMAed, I've had it for 2 weeks now and have been just about ignored for as long.

I wish I knew how to make the change permanent. Hopefully someone can chime in.

You have a business by any chance? Cost me ~500$ vs ~1600$ to import mine using my business.

P2Pool is working great for me, with both latest stock firmware and CK's custom CGminer build.

Heh - so much for negative difficulty.

No black friday deals, bitmain?

No, thank you, Guy. It's absolutely refreshing to see how you guys do business. It's the reason I'm considering spending more per GH with you guys.


Trust me, I hear you loud and clear. I'm stuck dealing with bitmain right now, for compensation and an rma for my latest S4 that came with a dead hash board. Dealing with them is horrible, like pulling teeth. I've got 4 other just about perfectly working S4s, though, and I can't really complain about them since their issues have mostly been resolved. Still a few bugs to squash and they'll be solid.

At the end of the day, ROI is still king though. I can get 8.8 TH/s for 200$ more if I go with S4s, vs 4.9 TH/s.

I really don't mean to thread shit SP, and I hope that's not how this is coming across. I'm legitimately trying to justify an SP31 and I'm hoping for someone to weigh in. It won't take much to be honest, if only to treat myself to the crème de la crème of Bitcoin hardware.

Grrr.. I really want to pull the trigger on an SP31, but it doesn't make sense to me. For $1600 I could have 2x S4, running at 4.4TH overclocked. Or even better 3x for $2400 @ 6.6TH/s. Am I missing something besides the obvious increase in hardware quality, density, and customer support of SP over bitmain? 

Still not working properly for me with 1.14, unfortunately. High rejects and low speed. Probably doesn't help that setting a fixed difficulty doesn't actually work properly. No matter what I set, westhash ends up resetting and spamming me with diff 20 work. I'd have to double check, but I;m pretty sure this also happens with A2 Terminators, but they handle it better than the Titanic.
