Got 2 more S4s in today, and both have issues. Will post more details tomorrow.
Will post more details tomorrow. 
I would have to agree with you. I have 16 S3's and 1 S4 at the moment. 4 more S4's are on the way.
I did notice something that caught my eye when you said, "no X's"
I know this is an S4 forum, but one of my S3's has a dash at the end of the zeros. what does that mean? "00000000-0000000-"

Not sure actually. X non-responsive? - dead. Just a guess. But a hard reset usually does the trick.
Okay
I'll reboot and see what happens first before doing a reset.
EDIT: REBOOTED AND IT"S STILL THERE
May have to do a hard reset like you said.
My S4 ran perfectly for a few days but is now getting x's and significantly reduced throughput. e.g. 3 x's is costing me about 10% hashrate.
This is happening at stock speed, at both .720 and .725 volts, with the same chips dying. Takes a few hours by the way for the chips to go offline.

Any suggestions? I'd like to see 2TH again.

You might have to do this and settle for 1.8 Th/s: If you read a couple of posts before this one I quoted, you will see the reason why.
Others perfecly normal only J7 connected hash board is unconfigurable, if you want to proof of that disconnect this board power cord and you will see chain 1 is gone and look at your power wattage. or try to configure voltage and repower again. i have 2 S4 and all of them have same problem.
and i found best configuration and best efficiency = 187.5 Mhz at 0.685 Volt (you can add this value like that = 0685)
this is the best...
and i found best configuration and best efficiency = 187.5 Mhz at 0.685 Volt (you can add this value like that = 0685)
this is the best...
Wow!
So, you recommend all of us with batch 2 to switch to 187.5 Mhz at 0.685 Volt?
Will doing this lower my hash rate?
If so, by how much will it lower the hash rate?
of course that is lower than 2Thash but also eat lower energy 
and also lower Temperature and lower noise like 1800Ghash 1060W
i think that voltage adjust problem is master reason of psu's blowing because developers unexpected situation like that.
they put a 12V 120A top limit psu and they expect 1200w power usage but not, some of hash boards still working warning limits...
NOTE: He said 1800Ghash @ 1060 watts.
I think he intended to say, "12A and 120V" instead of "12V and 120A" but I could be wrong.

are the new batches of s4's still having issues? I was hoping to order with the coupons they issued for $400 off but now I am having second thoughts and thinking of going with the other guy starts with an S idk gotta look them up.
I've ordered 1 already and got it on the Nov. 14th. It's been doing great for me. I have 4 more on the way. I've mounted 3 PDU's today on the wall. About to install a cutoff switch and run three 240V/30A circuits to it and then into the closet once the S4's arrive. I will keep mining off my 120V/20A until then.
Cat6 cables waiting to use.
Mounted PDU's with a gap from the wall to allow power cords to go behind them. A blue cord is already behind one for show. I did accidentally unplug it while installing the PDU's approximately 6.5 hours ago. However, what concerns me is best share is ZERO
EDIT: Switched from Slush to Eligius and immediately I have shares.
EDIT: I went back to Slush and still best share is ZERO.
I get paid for the TH/s at Slush. However, the best share is always ZERO at Slush.
I may switch to Eligius as soon as other S4's arrive.

My miner perfect work at a frequency of 268.75 - 275, and outputs the 2500-2700 ghesh
WTF? that's pretty good. Did you have to change the voltage too? Does yours run stable with no X's for a long time?
dont believe some like this, without powerful psu thats meanless..
There is absolutely no way to push the mhz to 275 on the supplied PSU. Hell, I can't even get it to run 250mhz and I'm on 220-240v (lower amp draw) in Singapore. The best I could get it to run stable is 231.25mhz at 0725v. But watch the tempreture. Mine goes up to 63-65C which I believe is still ok (there must be a reason why the cut off is at 80c). As long as you do not switch pools, or restart (not hard reset), the X's don't appear.

I don't mind but others might. If you feel you should create a New Topic, please post the link to that topic here for me please.
Thank you.
Well, to avoid causing any stress, I posted it here: http://asic.usertalk.info/index.php?topic=159.0 (that is a lightly used forum I maintain)
Cassey
Thank you!
Sorry late thanking you...
I'll have a look at topic tomorrow.
Still involved with trading coin...

Static or dynamic (DHCP) shouldn't matter - networking routing, firewalls, etc. will.
If you can connect to the IP address displayed on the unit while on the same subnet, BitMain has delivered. If the unit is not displaying an IP Address, then you either don't have dhcp running on that subnet, or the unit does not have a valid network connection (bad cable perhaps?), or the unit is broke - in decreasing order of probability.

Thank you for your contribution to this discussion, Cassey. Like I said, I'm not a specialist. I used YouTube videos to help me learn what I wanted to do with mine.

Sorry if I came across too strong there. Networking can be complex - like learning to swim. Tough to learn the basics, then it comes naturally. If the groups wants, I can post the basics - should only be a mildly long post...

I could be wrong on this: I would believe your network the S4 is connected to would need to be set up for DHCP and you know the address assigned to it [whether it was assigned automatically or manually as in my case] in order to connect to your S4.
Bitmaintech is not responsible for what you do with your network set up and whether you want to connect remotely or not. They are only responsible for the unit. If the unit had problems connecting to it remotely, THEN I could see bitmaintech coming into play.
However, I honestly believe you need to set up your S4 to connect to a DHCP network NOT static in order to connect to it remotely within that network.
I'm not a network specialist. I'm just telling you how I have mine setup with my Airport Extreme Base Station from Apple.

The DHCP server issues the static IP to the S4.

Nothing wrong with 60C, I'm almost permanently at 55-60C due to a 35-40C ambient.
But it is in a shopping centre with air-con and an ambient temp of 24C, so going by your temps it being 46C (coolest board) to 51C (hottest board) seems normal. I don't think the 61C is normal at that ambient temp of 24C. It was only 1 board that was reaching high temps, not all 4. The other 3 boards were still running at around the temp they normally are. I monitor this miner several times a day so I do know what my average is for my miner.It is currently stable with the hottest board at 51C now and hashing at 2TH.
This is a software problem. Sometimes i have it too, after power failure.
You can stop function - Stop running when temprerature is over 80℃ - only thing you need restart miner with PSU manually.
Hope this can be addressed with some kind of software update soon.
Well the first time it was running hot, it was not responding to via HTTP or SSH. It just crash and continued to run hot. So if it has crashed I'm not sure it would be able to monitor the temp and stop at 80C.
Could be a problem with board J7; as a previous contributor of this forum mentioned earlier.
