Topic: [CLOSED] Spondoolies-Tech SP30 - Specs: 6TH/s + 0.46W/GH - page 6. (Read 28529 times)

willing to bet 10 btc on it? The diff on 8/14 is >=42% higher than today?

We'll see what Spondoolies announces in terms of speed and power once they get their chips and have a chance to play with them in an actual system; there's no point in needless speculation since the chips will arrive soon enough.

The currently posted specs are 6TH/s (originally 5.4TH/s BTW) at 2400 watts. Whether that 2400W comes from 110V or 220V makes no difference. All the boards see is regulated 12V; they don't know, and don't care, what the wall voltage is. I plan to use two 110V 15A circuits to power an SP30, simply because that's what I have access to.

Voltage matters (higher efficiency and more stable power). Its not just about the amps. I recently had my house updated to 300A total due to a recent fire caused by all my mining gears (overloaded the main meter) and I had six 20A breakers installed just for mining.

The SP30's come with two server PSU's, so you can split them between two circuits, but the voltage has a big impact. You can check the SP10 threads, no one on 110v get's anywhere near 1.4TH/s. I believe the highest I remember reading about was 1.3TH/s, and that was with someone blasting the a/c right in the intake fans to keep everything very cool and stabilize the voltage so some doesn't get lost as heat, and with a lot of fiddling around with the settings.


EDIT:

Also, you should never max out your circuit breakers. Treat a 20A breaker as a 18A breaker. It's best to leave at least 10% headroom.
So it would be more like 18A * 110v = 1980w per circuit. The SP30's have two 1200w PSU's, presumably pulling 1300w each (they advertise 2500w total, I highly doubt that). So as long as you split between two different circuits, the amperage won't be an issue, but the voltage still will be.


In hindsight, I wish I had those guys install at least two 220v lines, I regret that -_-' It would've only cost me about $75 more at that time, now I would have to pay about $800 to have everything redone.

There are usually 15 and 20 amp circuits... 15a = 1800w 20a = 2400w

This machine will probably trip a 20a circuit... If I end up getting one I will have to use one plug from two circuits

Does everyone wanting these units have 220v+ to power these things? I run all my miners at 110v (USA), and the SP10's were doing about 1.2TH/s on 110v (1200w) vs the 1.4Th/s+ (1250w) advertised (which is on 220v+).

The SP30's were originally advertised as 5.8Th/s, I believe, before they changed it to 6Th/s even (probably due to the -/+10% variance). We'll probably be lucky to get 5Th/s out of these things at 110v.

Anyone's thoughts on this? It would be worth a lot less to me loosing 1Th/s.

 

haha... if he somehow negotiates $1000 for a Sept delivery SP30 I'll buy 100+. No joke.

Are you sure your magic crystal ball is working?

Are you forgetting spondoolies goal of 5,000 sp30/month?(soon to be 5,000 sp50/month) Or asicminers huge production capacity? Or megabigpowers "up to 50ph/month" franchising program? Or 21e6's secret mining operation? Or bitfurys 20MW mine? Bitmain? Avalon?

The list goes on..

we will no longer see 42% inc/month. 60 ph is 10,000 sp30s. per month.

Even with $3800 it will never ROI. For getting an ROI the price must be at $3000, that without considering shipping cost and local taxes. Dont say the bitcoin price will increase bullshit, if you are sure about the price increase then buy bitcoin directly now using the same amount, will give you more return.  The mining game is over unless the manufactures understand what is an ROI for the buyers, now they want to dig the gold with their own shovel.

The following difficulty increases will be higher than the past couple of ones as neptunes started to ship, more than 1000 SP10 and SP30's will be address to the network in no time.

Not saying its any ones fault, just sharing my thoughts..

Who cares what the value is because spondoolies doesn't. 6TH in September is not worth $5400 or even this special negotiated price of $4300 (price undetermined)

Why would anyone commit to a preorder without knowing the price? That's just adding an extra layer of gambling.

So will the entire group buy be canceled if the price is above $3800? (as the graph suggesta)

Spondoolies, why not cut the bullshit and just offer everyone in September batch the best price possible?

I have faith in you my friend! Make sure you get hosting prices as well. Some of us will want hosting given taxes last time we imported from sp. Also where is the datacenter located given all the unrest in the region?

As soon as I can fix a price per unit (in the next hours, I hope), I will publish it in the first message of the thread. Please keep patience : ) I said 15th July.

So how much are these things going to cost?

Feel free to do so.

SPTech know your offer and will be free to reject it

Randomly? OMG...
Have you really thought about that?
Or I have not explained well, or you have misunderstood me.

This is worse than explain that is 'capitalism' in Venezuela...

The group decides (not only I) how many units to buy; based on strong criteria, such as Difficulty or some than I'll explain.

Many buyers have told me (invented numbers for this example):
 "if the value is 5000$ I want 1 unit.
if the value is  2500$ I want 2.
if the value is 1000$ I want 5."

Someone has to spend around 5k, but fixed costs are diferente (delivery cost per unit, VAT/taxes, etc).

Due to the amount to units is directly proportional to the final price.

Well, and now value Vs Price:
The final price (value) of any miner is not define by the production cost of the product. The final price (value)  of SP-30 is due to the ROI and  profitability.

When a miner is not profitable, it stops producing. But the production cost is the same.
Price is the money that you pay for something (albeit junk).
Value is what I'm willing to pay for it (considering the ROI and profiability).

The value per unit is what I am negotiating.

I hope I explained it right this time : )

I will buy 30 units, if you negotiate $1000 for SP30.

I am serious, will PM you. If anything changes, I keep the right to refuse my reservation.

This makes absolutely no sense.

So basically you are going to exclude people randomly according to what you consider a "good deal"?

Will you be trashing the entire "group buy" when the final price ends up more than $3800/sp30?

Your estimations are so far from reality why should you decide how many units the group buys? (production costs of an sp30 are probably more than $2000)

Anyways if you do manage to negotiate the price down to $0 per sp30 count me in for 200.

ok will do tonight is that ok

Hi  rodeoclownicp


Enlighten me
