Good idea... I switched out managed APC PDU's for Tripplite recently, they're rated for 20A and they show only 8A (when 2 Antminer S3's are connected). Could be a couple of bad PDU's in the batch.

Yes, juan is bitmain USA. Just curious why people are buying these as they will never ROI unless the price skyrockets or the diff drops?

My first 5 S1's came from 112bit.com.
Took my money, shipped fast, and delivered what I paid for.
Goods guys as far as I can tell.

Now I buy directly from Bitmain for less and argue with customs.

This thread has gone 13 0 days without a 'NO ROI' post!

This is the best I can do. Optimal settings are 218.





Even running that cool, I can't squeeze anything else out of them.
The only thing I haven't done is remove and re-paste the heatsinks.
But I just don't think that's going to be it...

EDIT: Just FYI, I'm running --queue 1 with lower loads over the past few hours.

I really love this pic. BTCkenstein coming to life in the DC. Throw a mad scientist in there and the pic is perfect.

Those G4s take me back. Heavy as hell but reliable.

At this point I wouldn't.

Of course your purchase may be better handled then mine.

I sure can give a few reasons. How about you go back to page 143 of this thread and read about it. Here is a link to that post.

The long and short of it was ordered batch 1. 25.5 hours later account changed to a batch 2. No contact made Ever from their side about the alteration. Checked 14 days later to try and guess where in batch 1 I was and WOW suddenly I am overpaying not only for batch 1 but its now magically a batch 2. I start disputing the change. In 48 hours I got 1 email replied to the first never was replied to. Fair compensation for an item I do not want and was not contacted before someone acted as a purchasing agent was 0.02 btc. 112bit took my bitcoins, moved my order to a later batch (they oversold batch 1), made no effort to get my permission to alter our agreement and while in dispute shipped the damned thing. To make matters worse out of 7 emails I have received 3 replies in 8 days. I got my tracking # the day it was put into the depot (6 days after it was "shipped") of course being a good authorized distributor located in Florida USA the package came from China. Since it was handled so marvelously apparently batch 1, 2 or 3 really make no difference as to shipping day so 112bit doesn't seem concerned about it.

I'm waiting to know if he would agree to I think a more reasonable everything over 1.48 he charged me or a full refund. Of course Tuesday or Wednesday it heads back. Then reasonable is full refund.

I think I misread your sarcasm. Sorry.

BITMAIN really has to work on their customer relations. Missing refunds, careless customer service...
