Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 129. (Read 451266 times)

I don't understand why UPS can get stuff to me in 48 hours but F'nEx can't seem to get out of the country!  My shipment looks to be still sitting in China as well after being picked up 2 days ago.

It would be most helpful if you could work out this information with your shippers prior to sending out thousands of boxes.

FYI - FedEx importing to the USA needs to know that the device complies with Part II #7 if you are a home user.

Here's a link to the FCC form you could submit with your shipments that would alleviate any issues with the items coming into the US:

My S5 had spent 48 hr sitting in Shenzen customs. I understand when US customs ask for stuff here, but it is clear that something was probably missing at chinese customs as far as paperwork that should have been provided by BMT is concerned. Or did customs at shenzen got tired of miner deluge?

Anybody else had this experience? Comment from Bitmain?

Hi,

If anyone is interested, here is updated firmware for AntMiner S5 with extranonce.subscribe support and fresh cgminer version:

AntMiner S5:

(There is some additional features in S5 firmware, performance graphs like on sp20e, they can be accesed by pointing browser to http://miner_ip/cgi-bin/graph.rrd)

Example of s5 performance graph:

i do have a couple corsair 140 mm fans that came on the h100 cooler..
i also have a couple JetFlo 140 mm fans that came on the 140XL cooler..

think any of those will work good? they are rated at over 100 cfm at full speed.

but i dont want to mess the warranty up since i just got it today.. perhaps i can put it in a back room for a few lol.

I would not use those fans. The stock fan is louder, but it works. I have tested the S5 with the Noctua IPPS 3000 fan as in a push / pull config and can keep the temps in check. Everything goes back to stock loud fan until warranty period is all over. You need at least one fan that can push 250 CFM and can hit 3500-4000 rpm's or two fans each pushing over 110 CFM. Anything lower than that you will have a hard time keeping the unit at normal temps.

What effect does the missing chips have on the string voltage of the other chips? If you're losing a few don't you pay a double penalty in that you lose hashrate, but your power loss is largely unchanged and you'd also take a hit in the efficiency?

Up to 3 bad chips are within the advertised specs.  If you have more than 4 xs or missing chips, then you are qualified for the warranty claim at this point.

i dont care really how loud it is.. its the type of noise it makes
the fan that is on it runs at like 4000 rpms and it has a high pitch whine, i can hear it through the whole house.

i was thinking about putting a couple of these on it http://www.newegg.com/Product/Product.aspx?Item=N82E16835242011
i know they are loud too 18 db, but only run at 1000 rpm. i bet they would be much quieter..

now, the 87 cfm rating, push pull would be good enough to cool it?

The S5 is generally always a lot louder then an S3. Nothing you can do about it. You can get expensive fans but ill still be louder then an S3. They aren't good for home mining.

My Dad has 5 S5's but has a weird problem. He has an X and a missing 0. How does that happen? Tried a different power supply, tried just about everything.  What is causing this? Is a chip faulty on one of his boards? BitmaimWarranty, what should he do? Here is a screen shot of it. You'll notice one x in the line and zero dropped off at the end. Very confusing.
What do you think here???




I asked and did was Yoshi asked me to. Tried using the other data cable on the other port. Switched cables around completely. Flashed from the SD image the stock firmware. Tried another power supply. Let the miner sit for a good 30 minutes to cool down. Tried a different pool. Same thing. Seems that the right side board has some faulty chips on it. I told my Dad that there was nothing I could do and I'll ask Bitmain if they are able to help or not.  He just doesn't want the miner to start getting worse and then end up out of warranty with half the chips not working. He is capable of removing the faulty board, would BitmainWarranty replace the board for him via exchange in the mail from Colorado? I know there is a certain % + / - within spec, but the miner is only one day old. Should see bad chips or board issues now. Anyone else see a dropped zero or an x in their ASIC status like the picture above? Should I contact BitmainWarranty for him?

Thanks.

got my s5 up and running.. it is a lot louder then the s3..

is there a away to get the s3 fans and put them on it? would that void the warranty?

Hey, that chat should be 24/7 after a roll out!!!

These are my first bitmain boxes, I've used SP-Tech previously.

I'm pretty impressed so far, turned it on and it was hashing away 2 minutes later, doing 1.18gh/sec out of the box on decent temps.

Is there a way to change their frequency via a cron job like I can do with my sp20s?

My new S5 is superior to my other. No HW errors and a slightly better hashing rate. I'm impressed thus far.

Yep, default was changed to DHCP since S5s. It makes it a bit more interesting for bulk customers but better for individuals as it will always be accessible without intervention.

CE & FCC Testing/Certification Information

We heard some customers are experiencing a speed bump with the respective Customs Agency to include in USA.  Here are the copy of the certification documentations if one is required.

Antminer products are always build to pass the CE and FCC standards the CE mark we use is not the so called, "China Export" logo!  (not only in ASIC business but other manufactures in china are known to stamp the China Export Logo instead of CE certifications needed in EU)
 

Sometimes when I turn on one of my C1, it does not start mining... if I turn it off and turn it on again, it works... I hope it's not getting broken...

Really loving this machine.

Okay, up and running.  Wow.  It's light.  Surprised to find only 4 PCIE connections instead of 8.  I don't see anywhere in the GUI an option to change from CST to EDT.  Now to switch subnets.....

And didn't wake up to .1.99 but rather DHCP.  Glad I have nmap functional as my new router is a pain to log into.
