I just hate hearing someone else having issues with quality control. I have 18 S3's and all of them have been wonderful except for the PCIe port on one going bad. BITMAINTECH really messed up on the S4's debut. Whoever is responsible for supervising quality control at bitmaintech may need to be fired! I really hope BITMAIN gets the S5 done right on its debut. If they mess up the S5's debut, they will ruin their reputation and have a lot of us running towards Spondoolies, etc.

A lot of us think their reputation is already ruined. They are betraying their customers left and right. Might be too late for them to turn around.

I just think that ESPECIALLY if someone invests that much into that many rigs at one time, AT LEAST make sure the rigs work properly after 24 hours use at a minimum. The whole thing just stinks when investing that much money. More than likely, someone who invests that much will do so again. So, don't ruin it with poor quality control!!!!

The whole thing just stinks because I just said, "...they have the best equipment on the planet" in another forum. I HATE eating my words when I see stuff like this!!!

Bitmain Warranty - Are there issues with the power supply - I just received my 16 S4's and 2 had bad power supplies out of the box - yellow/red flashing lights. Now 3 others have died doing the same. Running at 240v in a NOC at 65 degrees F. Help...

Also 2 have 1 board show x's

I am about to order another 16 pack, but concerned about the reliability.

Batch one had that problem. It was supposed to have been fixed in batch two.

can antminer s4 use 220v. electricity?

Thanks for all your help Bitmain Warranty. We are setting up a warehouse all on 240 volts. Should be up and running next week. I will report back with power consumption.

Are you able to SSH in during one of those states and see what the cgminer window reports?

what command do I run while I am ssh into the S4 to check what the cgminer is doing?

I'm not actually sure off the top of my head, to get cgminer window. Someone else will know and be around soon enough.

it looks like cgminer is still going after the box stops hashing and the fans die down to about 2700

PID PPID USER STAT VSZ %VSZ %CPU COMMAND
31554 31553 root S < 147m 30% 98% /usr/bin/cgminer --bitmain-dev /dev/bi

I am working on disconnecting each blade and checking to see if the problem persists. I dont have another power supply - my other S4 has PCI-E connectors and this one does not. I dont like the idea but if the eliminating the blades dont work, bitmain support suggested i take my working S4 offline and use the motherboard from that one on the sick S4...

I am about 24 hours away from confirming the fix - i will post back if it works.

Do you think it's possible that Bitmain has confused Christmas with April Fool's Day?
That S4 'Xmas Special' is quite special if you are Bitmain &/or the hosting facility (which as a bonus is at an UNDISCLOSED location in the USA)!

Come on guys...

Go easy on him. He's simply making an offer. May be a bad offer but it's still an offer.

I actually believe many of us who have bought an S4 will wish we had known an S5 was around the corner THAT CLOSE!

So, those of you who also have an S4, please go easy on him.

In my opinion, we [who have bought S4's] were left out of the loop for someone else's profit. Yes, we will still ROI. However, it will take longer to ROI on the S4 than it will on the S5.

You have details on the S5?

Sorry, no details. Only speculation from the following forum: https://bitcointalk.org/index.php?topic=826519.180

How many people have upgraded the S4 firmware to: initramfs.bin.SD-20141016.tar.gz from the bitmain website?

I only ask because mine is still running on the factory firmware no problem with difficulty manually set, so I'm kind of wondering if I should bother with the upgrade.

I upgraded all of my S4's to this firmware and gained at least 5% hashing speed on the pool. I also set difficulty to 2048. 225 Mhz 0725 volts . They are all hashing at least 2200 and are stable meaning I don't have to hard reboot them every day for crashed chips or reduced hashing speeds.

Maybe I need to upgrade my firmware. When S4 hashing rate drop to below 1500 Gh/s, my pool with Ghash.IO goes to zero. I had difficulty set to 2048 manually.

Looks like your hashrate dropped to 0 over 14 hours ago. It just took that long for your average to get below 1500. I upgraded all of my S4's to the latest firmware (Oct 16) and have not had any issues, except I needed to reboot another time after the firmware upgrade, on all of them. All of them ran poorly after the automatic reboot from the firmware upgrade. But I always set the difficulty manually when the option is offered by the pool.

Do you know how high the board temps are getting? The UI shows 50-51 now, but it hasn't been hashing. I've seen this (hashrate drop to 0) happen with temps in the 60's. They should be able to handle 60, but I'm just passing along what I have seen. I have also seen this happen when trying to overclock with stock PSU. (I can see in your screenshot that you are not overclocking, but wanted to mention it anyway.)

You should setup some kind of alerting. You don't want to lose half a days worth of mining on an S4. There are a couple home grown monitoring programs out there. They require a bit of work to set them up. I see that Justin Ramos shares open-source monitoring software. I don't know him. I have tried his P2Pool code, which is good and has extra reporting. I intend to try his monitoring solution. I think you have to install 3 software packages. The API client, the manager, and the monitor. https://github.com/jramos

I also ran across this site, if you want fast and easy. http://www.awesomeminer.com/ There is a one time charge for the version that send notifications. There is a free version to try. I don't know this site and am not endorsing them, but their product looks good. If you search for "bitcoin mining monitoring", you will find others.

I have to manually set difficulty to 2048. Otherwise, it doesn't hash more than 180 Gh/s on the pool while S4 shows it's hashing 2000+ Gh/s. I check my S4 B2 which I received in early December which has latest firmware. I tried to set to 225 Mhz 0725 volts then it went to zero. But before, it never went to zero. When hashing speed drop below 1500 on the S4, pool goes to zero. When I set pool difficulty to anything less than 2048, it never hash more than the difficulty setting. S4 temperature never goes up above 52 since it's winter here and I have all the windows open.

I'm trying different settings to see which would work the best and optimized mining.

I didn't know pool went to zero since S4 was running. With other miners' noises, I tend to be not hear the noises as much. I guessed I have adapted to the miner noises.

Anyhow, thanks for your insight.

I hate to say it but there are only a few pools that you will get full speed hashing from I can find. I tried several and right now I have all S4's showing 2200 + at the pool. i can get them to 2300+ but the chips sometime crash. It is that difficulty rate issue. Some pools you can set the minimum and it works and others you just can't get them to full speed. I am not here to promote a pool but the one I use starts with an S.

My S4 B2 already has updated cgminer v4.6.1 It still only runs for couple hours and not hash anymore. I don't see chips crashing since all shows 00000s and no x. I'm going to reset the miner to factory setting and try again. Something is not right.

NO!!! Way higher price than Bitmain's real site. Bitmain's current price for the s4 is $1,200 USD + shipping https://bitmaintech.com/productDetail.htm?pid=00020140926075515819D846Og240603

No idea who owns the one in the link you gave....
