Question, if these boards are 50-75W then why is a 650W power supply needed for 1-2 boards and 1050W for 5-6 boards. That's almost 200W per board.

I have 30 GH coming later this week that will go on the pool. Not a lot but its something...

Check your PM

For a small amount you can probably create a coupon code and sell it to someone on here in exchange for paypal or a check/money order or whatever. Be sure to check trust of course. High risk of scammers with paypal.

Going with a refund, order 540. PM sent.

For scrypt coins you need a GPU. Many people seem to be using 7970s now.

They said late this week. There have been some delays, and you can get a refund if you want. Look back a few posts in this thread.

I'm order 620. I got an email for a payout address and replied to it, but order still shows no payout address?

In. Go DZ!

I disagree that the pricing of ASICs makes positive ROI impossible. I actually think the ROIs can be pretty good as investments go. I've looked at several opportunities recently that look like 50-100% ROI over a few months (BTC out vs. BTC in, although that methodology has issues too because ROI is not independent of the exchange rate). But you have to be very careful about what you buy, who you buy it from, delivery dates, etc.

I agree that eventually this will happen.  


Well many of the ASIC companies thus far have been scams or near scams or just incompetent. That's not an axiom of the market that must be true or always will be true, it is just what happened over the past year.  

"Past performance is not necessarily indicative of future return." This phrase is usually used to warn that future performance may be worse, but it can also work the other way.

BTW my response wasn't emotional, just a different point of view. Room for multiple opinions here I hope.

That would be great!


I didn't mean "combine" in the sense that you couldn't tell the difference, but think about it this way. The mining operation could use any public pool, but it doesn't, it uses its own p2pool node. No reason (other than a slight difference in the payout formula) not to treat that node as part of the pool, so the pool has two nodes, not just one. Lots of pools have multiple nodes.

That said, if the pool has 1 TH it doesn't matter that much.  

I'd suggest modifying this policy (with some neutral/fair adjustment for the altcoins, etc.) because the pool will become more popular if it already has more hash rate on it.

Or, it occurs to me that maybe the mining equipment is at a different location from the pool server? If that's the case, then multiple pool nodes are good to reduce latency, but consider them to all be part of the pool administratively and combine the stats.

Well eventually everything goes to economic break even in a mature market. But if you think mining is close to that you probably shouldn't be involved with a mining-focused endeavor. Maybe sell your seats?

I happen to think that mining is slowly moving toward a mature market but is nowhere near there yet. If you look at the difficulties that exist with buying mining equipment, constant missed ship dates, payment and refund issues, hardware reliability issues, etc. it is pretty clear we aren't there yet.

BTW (related to other post about loans) leverage can actually be a good thing in a near-mature market. If you have a small edge (say a high degree of competence in any of the above areas) you can turn it into a big edge in ROI.

The diversified stuff is great but don't count mining out yet. I see at least two big transitions coming in mining. Navigate those well and profit.

The "deflation" in myth. If you look back through my old posts (on some other thread last year) I've explained why. But it is true that bitcoin goes up a lot (bad for borrowers).  On the other hand it sometimes crashes (good for borrowers).

This is not intended to express an opinion on the proposal, just clear up a widely held misconception so people can think clearly about the issues.

Staying in for now, might even pick up more shares if they open up, but please keep us informed on the ETA.

Awesome.


Well I sold you my miner...But if I see any good deals quieter ones I'll surely point it there!

Very cool. We should promote this more widely (like on the mining pool list?). A lot of people would like a nice 0% pool.

So is R13 just not going to happen at all or is there a new ETA?

Yes I agree 50% might be extreme, but aiming for lower load rather than higher is still advantageous.

Take another look at that chart in the review above. Dropping from 80% to 60% the fan speed goes from 1500 to 800 rpm. That's a big difference in noise, fan wear, and vulnerability to PSU overheating.

The power savings from using platinum-rated PSUs and 240V is incremental on top of loading issues.

Don't spend unlimited money on this but err on the side of bigger.

That's misleading


Between 50% and 80% maybe but look at the chart references on this thread a few posts back (not by me so I'm not cherry picking). http://www.techpowerup.com/reviews/CoolerMaster/V850/5.html

If you go up to 100% you are down 2% from 40% or 50%, not 1%. But this is again somewhat misleading, see below.


It will save about 2% from running at full load or 1% from running at 80%. Even running at 80% is better than 100% though. If you are pulling 1000W 24/7 and paying 5c/kWh then the difference in power alone is $8/year, ignoring the power supply itself running cooler. If you are paying 15c this is $24/year.

Now when it comes to heat produced within the power supply, that ALL comes from the losses. If a power supply is 90% efficient, that is 10% losses. At 88% efficiency that is 12% losses, so 20% more heat, not just 2%. That's definitely significant to the temperature and cooling of the power supply.

I wouldn't pay a lot more for a bigger power supply but I would definitely pay somewhat more.
