Well I might consider buying but sill looking into the loud optinos you now. Is the contracts or hash lifetime until one sells it on in house exchange or is it limited time contracts or good to go. As if I buy equipment then the only problems  I have is 1 cos 2 shipping 3 import tax and 4 energy used and going of today's figures would be bare almost imposable brake even or cover costs.

I'm hurt.  Just checked my account and there's no coupons for me   You can reinstate my February coupons and I'll use them

if someone does not want to use their coupon(s) and wants to get rid of it/them, let me know (PM-mention coupon value and how much you want).
I am looking for one or two coupons max.

The 50C is really more of a "if you can get to here, great", but I accept that its unrealistic for 90% of people. You get <50 by adding an S3 fan on the end. The optimal running temp is simply anything less than too hot, which is 75-80C. Add in a safety factor (on top of the 80C's one) and you hit 65-70.

And mining bitcoins instead of whatever else pump-and-dump is much less likely to be profiting by ripping off n00bs. You know, if you have a conscience.

I have given away many coupons.


 This time I need a few s-5's 1 ,2 or 3 if possible.

please let me know if you have any to spare.

 my name at bitmaintech is

philipma1957

you can pm me here if you have 1 ,2 , 3.   thanks

same here. I am looking for a couple coupons as well. Let me know what you got and how much you want for them.

if you have proof of order number and the tx id you should be okay.
Bitmaintech is close to perfect on sending paid for gear to the buyer that paid for it.

Possible bug in firmware. A critical one.

I had my pool drop out on me, they were having problems and I was disconnected, so the miner wasn't hashing. The fan slowed down to almost like 100-200 RPMs but the temperature kept rising. The fan NEEDS to keep running to keep the ASIC chips cools weather hashing or not it seems. Temps went up to 75-80 so I turned them off right away to let them cool. Bitmain, you need to review the firmware so that when the rig gets disconnected from the pool it doesn't disrupt the fan speed to keeping the chips cool. If I wasn't home and didn't hear the beeping sound I'm wondering how high that temperature could of went to. I actually felt the heat if I put my hand over the miner. It can't just be ambient temps, because these chips cool really quickly...so something else is going on here. If you want to try and test, pull your ethernet cable out and see if your fan stops or slows down and watch your temps closely.

Once I re-established a connection, everything looks good. Any ideas on this? We don't want burnt up miners, right?
