I cannot understand why the reduce the prices every day?

That way, everyone would wait to buy until it gets stabilized.

Why? Miners not selling so great these days.

To many faulty units, less interest. People moved away from mining.
Look s1 thread, almost every day price dropping and few fishes catches in that net.

If people would stop buying than you would see gap between price now and real price which market dictates.

Less demand lower prices.

[tzortz]

I mean, that the reductions they make each day is higher than the profit from mining.

Why should I buy knowing that the reduction is running faster than my ROI?

Just yesterday you were complaining how these were too expensive and the SP10 was better and now you are complaining that they are dropping the price? ... make up your mind.

Do you just complain for the sake of complaining... We get it, you are a SP10 fanboy but stop trolling.

I was complaining when they were overpriced at $3699.

Reducing their prices without a reason showing their huge margins.

I apologize for expressing my thoughts, I will ask you next before I post anything.

[freebit13]

Oh please! The current price for an S2 in BTC is about the same as the price for batch 2 in BTC, so buying now still returns less BTC, so roi will be less likely. You still got a better deal, stop worrying about it.

You will lose minig profits if you wait.. it makes zero sense to wait.  The price isn't dropping fast enough to justify waiting nor should it drop that fast.

I am not complaining in favor of any manufacturer, nor I am a fan-boy of anyone.

I own all kind of gear, from 5x LKetc, 2x Bitmines, 30x S1s (resold also at least 70pcs), 4 S2s, etc.

What I am trying to achieve is in favor of us, the customers.

And also am I trolling discussing about the every day price reductions being made by Bitmain?

The reduction made in 2 days is 2599 - 2529 = $70.

With a single Terra you will not earn $70 in 2 days. You will earn $54 minus the electricity, making it less than $48.

Where am I wrong?

The price the S2 is at is too high - Bitmain is focused on bringing it down to reasonable prices 1 day at a time, just like when they jumped the S1 price down from 0.8BTC to 0.6BTC to catch up to the difficulty trends.

The S2 has 10x the chips and 5.5x the speed of an S1, but still costsa about 11x the price of an S1.   That makes it less appealing as a purchase

There are 640 chips on S2 and 64 on S1...right?

So... if 64 chip S1 = 0.45 BTC (with coupon)... 640 chip S2 should be 4.5 BTC .... Current price of S2 with coupon is 4.695 BTC --- I am sure the additional 0.195 BTC covers the PSU cost.

It only makes sense to purchase multiple S1s if you have access to very cheap electricity in this case 10xS1 at $0.1 kW/h will give you better profit margin then just having 1xS1... Majority of us unfortunately pay anywhere from $0.15 - $0.3 kW/h for this reason S2 makes sense for some people. Obviously there are other issues like having enough room for 10xS1, or the amount of power it is required, heat issues etc...

Only way I can see it making sense is that Bitmain Tech to release a smaller power efficient chip.

But heck I could be wrong.

I must have been one of the last purchasers from Batch 3, I feel a little hard done by when they announce a 4th batch $600 lessor in price when they hadn't even dispatched my order yet... Anyway moving along, I don't if this has been raised but I'm curious about the Quality Assurance standards are with Bitmain. I just received my S2 and its been running for 8hrs now and I've been monitoring it for the last couple of hours and the hash rate has been falling about 10gh an hour for the last 3 hours and its now sitting @ 935GH/S (avg). What this the tolerance of hitting the target? Because >-5% doesn't seem acceptable.

Could be temperature related. What are the temps on the 10 Chains?

Theyre all sitting between 47-53 with the exception of one @ 31.

OK the S2 now has been running for 16hrs and the (avg) has dropped down to 903gh/s. I've emailed Bitmain about getting a replacement but haven't heard back yet. Has anyone had any experience with Bitmain when it comes to warranty issues, or how supportive they are in resolving these types of issues?
 

You'll need to RMA your current S2 back to bitmain and they will send a replacement out to you. Could take 2 or more weeks.

This is an ongoing issue with Bitmain in general. I too was just hit with a failed part, and the turn around on failed product WILL result in serious loss in mining payouts. There is an advantage to going with Bitmain for mining hardware, however due to their support on hardware with issues, you need to factor in as serious losses in revenue .

The only thing that makes the S2 less appealing is the possibility of having hardware issues, or the POPULAR flash card issues, and then having to wait on a RMA while watching potential revenue pass you by. Trust me, when something goes wrong, speed in resolving the issue in my mind is not a major concern of Bitmain.

Are you sure all blades working well?

As tzortz said above, are you sure all blades are working well? Do you see green lights flashing on all of them?

You might just have a faulty board or 2. Try by taking them out: take one out, boot up and see if it runs at 900 Gh/s or 800Gh/s. If it runs at 800, then put that board back in and take out another one and try again... that way you can narrow it down to which boards are faulty and send those ones instead of sending the whole machine... that way you can still mine at 800-900 Gh/s while you wait.

I emailed Bitmain about my faulty machine, it took 2 days to reply, but they sent all the necessary details to RMA, with postage at their cost.

Thanks for the advice, I wasn't quite sure what to do but that is a pretty sound solution there. I was fearing that Bitmain would just ignore me and I'll be stuck with a faulty rig.

I'll post some results in a couple of days as it takes a few hours for the hashing speed to start falling.

Test so far was restarting it about 6.5hrs ago and its already fallen down to 958.14(avg).

Sounds like you might only have 1 board that's faulty, just pull them out one by one (obviously power down in-between) and wait till you see it stable at 900Gh/s, then the board that's out is faulty.

Also check the boards carefully, one of mine was missing one of these little yellow pieces from between the chips and it still worked, but wasn't very stable. I just put it back in place and painted the ends with silver conductive paint and the board seems fine now:

I left it running over night and check the speed in the morning, the speed reduced down to about 850(avg).

I've removed a suspicious blade that was running about 15-20 degrees cooler than the others. Its only been running for about 15min so I'll have to wait for the results to come in, but at a glance the speeds is holding at approx 900GH(avg). If it maintains that speed after about 6 hours then I will remove another card and put it into the empty slot to determine if the fault is on the backplane or the blade.

This is an ongoing issue with Bitmain in general. I too was just hit with a failed part, and the turn around on failed product WILL result in serious loss in mining payouts. There is an advantage to going with Bitmain for mining hardware, however due to their support on hardware with issues, you need to factor in as serious losses in revenue .

Yeah I've accepted that I will probably never reach ROI, and its very frustrating/depressing watching your investment go from bad to worse.

I have 2 S2 to sell at $2500 USD shipped directly from BitMain, brand new of course!! If interested please contact me.
