necessary thing for the BTC owner

brianoakes, would you please share on the circumstances of how your psu died?  I have just received 5 A2 Mega's and have been running them at 1200mhz (getting 110mhs) for the past day or so, but I'm worried that it might be putting too much stress on the psu.  What were your settings before your psu died and for how long were they running?

PM sent.  I'm still out of 10.12426095 bitcoins from using the email payment feature, I really hope this will be fixed soon, it's been more than a day now.

Eric, I had approximately 10 bitcoins in my account just now, and used the send to email feature to send all the coins to my brother, using his gmail address.

My brother clicked on the email link, registered a new account, but does not see the bitcoins. 

This is very worrisome, as the site says that the coins will be held for 30 days, if not claimed will be credited back to me.  Does this mean that neither will my brother or I see the coins for another 30 days? 

J4bberwock, payment sent, please see PM for delivery address.  looking forward to receiving my boards!

Hi, I'd like to get 2 of the 2880w breakout boards, shipped to Taiwan.  Do I pm you address and send payment w/ shipping included?

Edit: 2 boards w/ 6 long pcie cables.  Taichung, Taiwan 406.

yikes

Can I have the url to alternate page?  I just deposited 5 btc couple hours ago, and haven't been able to log in yet, getting a little anxious.  Sign-in page loads, but after entering credentials it just goes to a blank page, I hope it's not some sort of man in the middle attack.

sure, whatever floats your boat i guess.  i on the other hand don't like replacing dead psu's or the risk of fire hazards.

emailed Bitmain tech support and gotten the following response:

Hello sir,
first of all your room temperature is a really high.

can you lower it to 25C?

since any unit that you have will die on 32c.
no matter how ventilated area is.

i would not suggest you units to go over 65C.

and if it is possible, just to extend their lives, can you turn them off for 2 hours during hottest time of day?
they will last longer.

we do not see a reason for replacing working units.


best regards,

i'm sure the chips themselves are, not too worried about those, but what about other components on the board? wiring?

i just received 3 units, i had ordered from DHgate.  in the process of testing them, i found out that the problem with them is due to a factory default cgminer setting "api-allow" that is set to accept commands from "W:0/0".  what i did is i ssh'd in and manually configured the setting to "W:127.0.0.1,W:192.168.1.0/24".  i wasn't sure which of the files were responsible, so i changed all that i can find, in /etc and /config. this is also a good time to change queue to 1 instead of the factory 8192.

2 of the s4+'s are exhibiting hotter temperature, 6C hotter than yours.  the one normal acting one is at 70C/71C, which i'm not worried about.  i am in contact with bitmain support about this and hopefully they can help me resolve this problem.  i'm squeamish about opening them up and readjusting heatsink/reapplying thermal paste, hopefully i can get RMA units sent to me instead.  

also, has anyone updated their firmware to s4p_20150518?  after updating the option to halt units at 80C has been changed to 95C!  i think this is a bit dangerous as i'm concerned about other components in the unit being able to operate safely at this kind of heat level. anyone care to chime in on this?

this is interesting to me as well, i just received 3 units that I purchased through DHgate and was considering purchasing more units. maybe we can organise a group buy to get a good deal?

this looks interesting, i'd be in for 12 (assuming you'd need 4 blocks per s4+ right?). where are you located?
