ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[thesmokingman]

Yeah I def hope that bad boy is wrong. Waiting on UPS to deliver my Batch 7 and was playing around with numbers to figure out potential payouts to ROI before July combined with my S5s, but seeing that difficulty (if true) just crushed those dreams even with running it on my one circuit with free power. Hopefully the diff drop leading up to the halving drops considerably with everyone taking miners offline to sell and I can make some ground up by mining through the halving.

Yikes...

Just used the Alloscomp mining calculator and it estimates the difficulty will jump 33% in 4-5 days (from 70+ billion to 92+ billion)

That's just insane lol

Sounds like it's time for you to go to the following thread to place a bet:

Looks like selling miners on ebay is a disaster.
Have a buyer that issued a chargeback claim to their credit card for a purchase 60 days ago.
Ebay doesn't know about it.
Paypal knows about it but the buyer only filed a complaint with their credit card so paypal will only accept
whatever the credit card decides to do. They have the credit card info but will not share it with me.
Told me I will probably have to file a police report for theft. Unbelievable.

Buyer has 4 miners AND the cash. Looks like I will be the one to eat it.

I don't know how anyone can do business like this. Blatant fraud goes completely unchecked.

Really?

So, PayPal did not help or eat the cost?

Unbelievable...

UPS just dropped off my S7 and it's hooked up to an EVGA 1600w Platinum ATX PSU hashing until my items from Finksy arrive and I hook it up to a Bladecenter 2880w PSU.

Only complaint so far is the machine is making a sort of high pitched whistling sound that comes and goes, sounds like a heart rate monitor when someone dies and it gives off that constant tone/flat line. Figured I'd let it run for a while to see if it dissipates on its own before trying to troubleshoot it. Anyone else have this issue?

If I hold my hand up kinda close to the back fan the sounds stops. So some kind of rig for that?
Mine are in a datacenter so it can woo woo all day.
I used to put a gutted 120mm fan as a spacer between my s5 front fan and the chassis with 90mm screws.
Also put little spacers between the front grille and the fan giving about a quarter inch of space all around the edge of the grille.
Quieted down the s5 a bit. Fan is more efficient also.
The fan is really too close to the chassis on the s5 and s7.
So maybe a spacer between the back fan and the chassis?

I would agree with using your hand to investigate.  What I did was use two fingers extended out over the edge over the back fan and the front fan.  I would move my two fingers (index and middle finger) around the edge in a circular motion until my fingers were at a point where the noise was no longer audible.  Once I found the location where the air being sucked in was no longer audible, I placed only one finger (my index finger) over the same spot and the sound was still no longer audible until I moved my index finger to another location.  So, I was able to find the "sweet spot" to place the tape on the grille of the intake fan in front.

Every rig does not have the radiator type heat sinks in the exact same location on every chip.  Some could be off or aligned in a certain way after manufacturing that allows for a whistling sound as wind is sucked in between the fins of the heat sinks when they are positioned just right.  Since every rig does not have heat sinks in the exact same location and the exact same size [varying by thousandths of an inch]... this whistling noise is audible only on a small percentage of rigs that have these heat sinks aligned just right to allow for this audible noise.

This is why I feel a small piece of tape is sufficient to reduce the amount of air across particular heat sink(s) causing the noise.  I noticed one miner had placed a piece of foam on the shelf in front of the fan to reduce the noise because that just happened to be the location on his particular S7 where heatsink fins were aligned just right to allow for the whistling noise.  The location of where the wind rushes in across heatsinks will vary from one rig to another more than likely.

That's scary to hear.  Did the buyer have any positive feedback?  I honestly have not had a problem selling a bunch of S3's and my S5's on ebay, but the buyers all had good positive feedback.

The buyer was a "Guest User" for one time purchase.  Wolfen, told me some of the details before.  It's crazy isn't it?  PayPal should be the one responsible.  They should make sure potential buyers are fully vetted before allowing them to make a purchase over $99 USD from a seller.  The entire episode is a crock of shiznit!

I've learned [now] I will NOT complete a sell to anyone with less than 10 feedbacks if what I'm selling is over $100.  PERIOD...

I don't care if I get negative feedback!  I'm not selling to anyone with less than 10 positive feedbacks as a buyer.

Yea, F that.  If he was a guest user I would simply cancel the sale and re-list.  Bunch of BS that Ebay lets you get scammed...plus they charge you the fees for being scammed as well.

[dmwardjr]

I would think eBay will credit back the fees if he gives them a call to explain the situation.  He should not be charged back $1,600 from PayPal because they were the one's who basically says the buyer is okay.  

Bottom line:  Don't sell to anyone with less than 10 positive feedbacks as a buyer for a large amount of money.  They should have an approved PayPal account with confirmed address by that time.

EDIT:

They wanted him to file a police report...  Well, with which precinct?  The one where the person who scammed him lives [Remind you he doesn't have that information]?  With precinct in same city as PayPal headquarters?  With his own precinct?  The whole thing is just bull shiznit!  I believe PayPal should be sued.  However, they probably covered their ass in the user agreement.

I've heard similar stories like that before. IIRC OgNasty was scammed similarly when selling a few miners on eBay. They were worth less than $1600 but he was still out of the money and the miners.

I think the real bottom line is to not sell on eBay period.. I've heard way too many stories about legit sellers being ripped off by fraudulent buyers for my liking.

Problem is, it's easy to sell on ebay than anywhere else.  I posted 3 S5's and sold them all the same day on ebay.  I could put them out in the forums here and not get any real interest for weeks since nobody wants them anymore.

That's a fair point, but I think I'd rather play the market here on Bitcointalk for a couple weeks than sell something worth > $1000 on eBay the day it's posted and risk being scammed.

May be you could file a mail fraud claim. Not sure if it is applicable if you used other carriers than USPS.

Got a point there.  Or take it to small claims court since it is less than $5,000.  The perpetrator would receive a summons to show up in court.  If they do not go to court, they will go to jail and be delivered to court in shackles.

Was Paypal still a part of Ebay 60 days ago? If so, they should be on the hook for something...

Exactly...  THEY should be the one filing the damn police report and giving wolfen back his money.

This.  And you can get high prices on ebay that nobody on this forum would ever pay.  I sold some miners recently and I was a little nervous when a person with only 16 ratings bid on it but they sold to people with more than 30 ratings. 

Are you allowed to put in the listing that you will not sell to anyone with less than 10 ratings (or whatever cutoff)?  In the buyer requirements you can only select to block users who "Have a feedback score of -1 or lower" which basically means they already misbehaved in at least one transaction.

Also it seems to me that if they gave positive feedback they should be essentially giving up any right to bitch about the sale later.

I'd just post it on a local internet listing, like kijiji.ca where I live.  A fellow bitcoin enthusiast will contact you and buy it with cash, or bitcoin.  easy, maybe not as safe as the guy is coming over to your house / meet in public, but whatever you screen people based on their grammar   OF course, this is only valid if you actually sell at a reasonable price, if you want to scam people into paying really high prices, like on ebay, then...well...go complain somewhere else you cant sell ༼ つ ◕_◕ ༽つ s5 should be able to sell for 300$ no?

Yes, you can put whatever stipulations in the auction or buy-it-now.  I know eBay says otherwise.  However, you do risk a negative feedback.  The worse they can say in the negative feedback is you did not ship the item to them.  You can also respond to their feedback stating WHY you did not ship to them and that you sent their money back to them.  You can also block that buyer from participating in future auctions of yours.

I also intend to search PayPal user agreement for sellers to see how they get away with chargeback claims being charged back to the seller after the buyer has kept merchandise and made no effort to return it.  I will then post that part of the user agreement in the auction or buy-it-now for the item up for sell so there is no confusion.
