Spending $200 and $50 is a whole different story, you are taking it to an extreme when I mentioned a medium in between of spending a few extra bucks. Spending $50 on a corsair cx500 and spending $70 on a better power supply with decent components sounds reasonable.

Someone doing it different than me has nothing to do with "doing it wrong". Antminer have limited warranty, people live in different conditions. If you have issues with your power supply 4months down the road you will wish you had spent $20 more. Anyone who appreciates hardware knows the one thing you don't do is cheap out on the power supply.


CX500 is $30 AR not $50. I've bought those and would buy again if I needed a good cheap small PSU. Just like I'd buy EVGA 1300 again if I needed a good cheap powerful PSU. I don't know what Antminer warranty has to do with anything, or living conditions.

"Doing it wrong" are your words not mine. See, I don't tell how you should run things, but you seem to be so worried that others are doing it not according to your rules that you resort to calling them "dumb" etc. I will not wish I had spent $20 more, or $40 more as the case might be. I will be happy that I can afford a spare and zero downtime rather than losing revenue while RMAing a "high quality" PSU (yes, those break too). To each their own.

You mean the part after they take my legitimate concern of something they should research and insult with sarcastic comments? Yes, if I am telling someone they should look into what they buy instead of saying "its good" because you plug it in and it works, then so be it. There is no point of arguing the quality of a CX500 because it's been done and proven.

Mail in rebate is a rebate. You pay $50 today so regardless of the time you wait to receive it does not change the fact $50 left your wallet today.

Living conditions has much to do with this. If you have 115 F ambient your components run at different temperatures then someone in Alaska. I doubt you will want to cheap out on a power supply that has components that are cheaper and rated for less temperature

Wait really? I always thought a mail in rebate WASNT a rebate. Huh, guess i should have done my research. Anyway, thanks for the insightful info!

guys, will this PSU: Seasonic G Series G-550 - 550 Watt 80 PLUS® Gold Certified (SSR-550RM)
handle 1 not overclocked S3? Just yes/no answer please. I've been seeing people ask similar question and answers ending up in OFFTOPIC, like overclocking and using absolutely different PSU. I just want to know that  this thing can handle S3 for long term.

Thank you in advance for the answer whoever you are!

Yes, it will handle one S3, overclocked or not. It maybe is not most rational choice for S3 PSU since it is an overkill for one S3, but not enough for two of them. Why dont you go with 750W version, that way you will not have to buy another PSU if you choose to buy another S3?

Current Difficulty
Bitcoin's current difficulty is 19,729,645,941

That became true when the final block of round 156 (block number 314,496) was mined 3.74 hours ago.

Predicted Difficulty
The longest block chain on the Bitcoin network is currently predicting a new difficulty of 21,970,933,720 to take hold in approximately 12 days, 9 hours, 56 minutes and 41 seconds. This statement is said with 1.24% accuracy.

The difficulty prediction is 1.24% accurate because 1.24% of the 2,016 blocks required in this round before the network difficulty is re-calculated have been mined.

The longest block chain is currently 314,520 blocks in length. So we have mined 24 blocks thus far and we have 1,992 blocks remaining before the next difficulty change.

The network needs some time on the new difficulty before the next difficulty jump can be predicted with some accuracy. You'll probably get that figure tommorow. That being said, there's much better difficulty jump prediction at https://bitcoinwisdom.com/bitcoin/difficulty.

Has anyone seen the next estimated next est diff level..?

Next difficulty retarget occurs at block 316511.0 (eta 12.4 days): 24080944291.1 / +22.1% [est.]

I know it's only estimated but even so, yikes...!  Shocked

https://bitcoinwisdom.com/bitcoin/difficulty

Where the hell are you seeing 22%? Even so, you can't really make any predictions on the next jump immediately after the current jump. This is when the large DCs and manufactures ramp up their farms. They inevitably turn down the their hardware about 7 days prior to the change to average out the next jump.

My bet is 8-10%.

So! All units are hashing over 440gh (Two over 490), but only when using a cronjob to restart the cgminer service every 1/2 hour - 1hr depending on the miner.
Regardless of how long I leave any of these guys up to "stabilize", they always fall to 390-398 after 48 hours.

There's only one thing. I am noticing a rather high number of duplicate shares poolside since starting this restart routine. (surprise)
Is there a cgminer flag among the bitmain options to clear the asic of all work upon a cgminer restart? I know the A1 miners have a similar command with '--hwreset'

Restarting every 30 minutes is a bad practice.
Try replacing thermal paste grease and I think the issue will be solved.

I'm pretty aware how just how shitty it is, but unfortunately after re-pasting two units I saw a decrease in running temperatures but was still experiencing a steep drop off in hash after about 25-35 minutes. One of the units will spike back up to about 470 but never enough to average out to 440 without cgminer restarts.

I wish I could attribute this to poor labor skill on my part, but I'm just about 100% certain I don't suck at apply thermal paste. =/




what kind of thermal paste did u use ??

Ceramique


ok.. do not use AS5 thermal paste and do not place
the plate upside down like this idiot tried to do below:
http://i62.tinypic.com/k9bapy.jpg[/img]

check your heat sink is placed right way:
http://i59.tinypic.com/2l9nubs.jpg[/img]

with all those "-" it looks like you have a cooling issue on that blade.
look at your plate did you place it upside down by accident ??

Hahaha, no no definitely didn't remount the plate upside down. However, if my heatsinks were machined/cast anywhere NEAR as well as the ones in that unit I probably wouldn't have any problems.

Is it a good idea to remove heatsinks and apply new thermal paste immediately when receiving the units?

If someone could please post a few pics about what´s needed to be done. I dont know once i open S3 what to do. You clean up old thermal paste, and where do you apply new thermal paste? just have no idea. thx! a few pictures would help Tongue

is this worth it? someone managed to make roi on those? how much the earning before you throw it on the wc? i was thinking of buying one

Are you kidding? the s3 has been around a few weeks only, and ROI takes over 100 days, just use the following calculators:
https://bitcoinwisdom.com/bitcoin/calculator

http://www.vnbitcoin.org/bitcoincalculator.php

This question will be a proper question by the end of the year.

If Bitmain changes to their old selling model, and decides to go to sale from stock instead of pre orders it may help a little, since instead of having to wait 1 or 2 weeks, you will only wait 48 hours for shipping.

The pricing of the S3 is so that it barely ROI, most others do not ROI.

And if for some reason bitcoin price drops the S3 goes up in price and you will definitely not ROI, at the beginning of batch 5 the price was 0.64 then it went up to 0.68, now it is at 0.66, however difficulty has continuously gone up during this period.

I am waiting myself for the price to drop, the ones that buy independent of ROI will not ROI but will enjoy the fun of mining, the ones that wait will enjoy double fun ROI and mining, and who knows if during that time a better deals appears.

The next best deal seems to be the sp30, however that is a pre order of 1.5 months maybe 2 months until they change their model of sales it is a worse option, however if the start selling from stock it could change things a lot taking into consideration that the power supply it is already included, in such a case it is easy to compare just plugs numbers in the calculators and see which ROIs first.

Any official notice of why the message feature was removed from bitmaintech?

Have the same question... After I wrote my message to them, couple hours later the "message" feature just dissapeared from their website.

I saw someone here mention they emailed the [email protected], I am still curious if the message feature is gone for good. It was a clean looking system to log messages and keep track
