This is the highest speed I can get.


At least your hardware error rate is zero Cheesy

Haha. But on a serious note, try it with only one module ? Does the green light  blinks on any of the modules ?

How about a panoramic?







Can you guess which one I had to set-up in a hurry without all the shelves I needed? If one of those S1's in the center dies, it's staying dead! lol, they're all zip tied together!

Can you tell which are the Batch 1 and which are the Batch 2+? hint: LCD Backlights






Very impressive, 52-54TH?

Not having fun with these.

Had to drill the screws to plug in the stupid ribbon cable. Had to take out a fan to get there. Internal ethernet cable is busted, had to replace it. Everything inside is covered in spooge. All the cards are loose and shaky.

Now Im stuck at 0gh/s. anyone have any ideas?

Hrm, got Rev 3 it seems:




Did you put that hole in the side for the PSU fan ? Or is that a late batch 2 case ? My B2 does not have that case..

Interesting. I am curious as well. This is how they should have been designed. All of my cases are closed and the PSU turned inside, thus blowing the hot air inside the unit.

That's an intake fan, not exhaust.

Sounds like a mod-car racer phrases. Fast and furious or something like that.

The batch 2 unit I was having trouble with has run all night without one blade.

Weighing up the options here, RMA PSU will cost way too much mining time, replace PSU by buying one locally will cost more than the one blade will actually mine, suck it down seems to be an attractive option. It's a minor problem compared to other stories being reported here, 6 S2 units in total, one blade unusable.

Run a Bitcoin node.
My S2 has been mining overnight, so roughly 12+ hours now.  According to the graph on BTC Guild it was roughly 1 TH/s the whole time, with minor variations.

It was mining on my table at home, now I have moved it to my rack cabinet and I'm having some trouble.  It has powered up and started mining, but I can no longer access the web page or ssh into the miner!

I hate being locked out.  Has anyone had this problem?  Any solutions?

Edit: I can ping it.

I have one antminer S2 acting up.. runs fine for like 45 minutes but then powers it self off and can't power it on again for at least 10 minutes.
Something maybe faulty with a capacitor? or perhaps the PSU thats not able to actually hold the amount of power draw from the antminer?
Any advice?

Thanks

I think its the PSU, when removing all the boards and connections so only the PSU is connected the PSU won't power on either.. have to wait for at least 10 minutes to get it working again.
Damn I wished they kept with the platimax instead of the gold revision of enermax.

Silly quest but is mobop jumper installed

Next pull ctrl bd out pull all plugs out sd card etc and reinsert

I received my unit, which just kept powering down after about 30 minutes. All temps were in the low 50's. The issue was the power supply which was probably overheating. I couldn't get the psu to turn back on even when unplugged from the unit without letting it sit a while. I replaced it with a 1350 watt psu, I had and now it's working at least. The outside cover on mine was also bent leaving a air gap in the front. I almost had to use a drill bit to remove the screws on the cover too. I ended up using pliers and force to get them out. All of these issues could have been address with almost no expense. Air intake hole for the psu and some better screws on the case.

I am sorry you had issues .  what was your 1350 watt replacement psu?

i wanted to be wrong about the psu.

i would be looking to get one today.
 still running the ant miner s-1s

and since many people have had a lot of issues i may stick with the s-1s longer then I thought I would.


Yeah, I run a load of S1's, but sorry Bitmain, you seem to have made a few too many errors with the S2 right now. Other companies are near delivery, and S2 is out of stock like so many 1/TH+ machines ... maybe my 'AntFarm' will become 'another' farm soon ...

Interesting. I am curious as well. This is how they should have been designed. All of my cases are closed and the PSU turned inside, thus blowing the hot air inside the unit.

ATX PSUs vent hot air out the back (where the plug socket resides).

Yes so the psu was pulling hot air out of the unit.  i.e. a hot box test. see jonnyguru.com


 not easy on a psu being asked to run at full capacity 24/7/365.


this new idea will make the chips run hotter and the psu will be a little bit cooler. since it will draw in cooler outside air.



TO all this is an under-speced psu for the s-2.  you need a decent 1200 watter to run  24/7/365 with this unit.


you guys can look back at my posts here

I see. Thanks a lot for clarifying and informing me, but the air inside is still hotter because of the modules, would rather it pulled from the room instead.  Was hoping I would not have to buy another PSU since I don't plan over clocking.  Giving it one last go, hopefully they run for more than 12 hours today before upgrading.

they are all under powered via the psu.  


the unit calls for a 1200 watt psu not a 1000 watt unit.


not half of the stock psu's will last 60 days pulling the watts these units pull.

bitmain tech must have gotten an offer he could not refuse for these psu's.   I have this psu on preorder from amazon

 I will order an s-2 when I get this psu
