I switched to Kano pool, looks good, I like that stats update really fast, and you have lots of them. UNFORTUNATELY, I had to change settings in the antminer batch 8, big mistake, as it took many "soft reboots" and 2 actual "reboots" to get it at 4720ghs, with good hw. I also see lots of X's for the chips, but thats just a bad reading or something because the hashrate is good and it goes away after 5 minutes.
Note to self: dont ever change anything in the settings ever again. ever.

Here are the current stats for my wolfpack These are running in a datacenter. Temps seem a bit cool. 218 will be here tomorrow. These are all batch ones.

Nice pack of miners. Why are they named S5:#.###? They are S7's not S5's. xD *Not OCD at all*

Nice list Wolfen. Thanks also for recommending M Miner Monitor - I have been using since our last PM and I think I will be lost without it. All my 7 x S7s and 1 x S5 are monitored using this gem of an app, and used with TeamViewer on my Android phone. When I am travelling, I can also get wifey to keep an eye on the M Miner Monitor - sweet! Now .... when is the block coming?

If I provided you good and useful info or just a smile to your day, consider sending me merit points to further validate this Bitcointalk account ~ useful for future account recovery...

PM your email and I'll send you a copy. Or you can get it from citronick I cannot find it on the web any more.

The earlier batches probably have more, undervolted chips. While the later batches have less, overvolted chips. So i'm guessing the earlier batches with the most chips would be able to get the most out of overvolting.
Assuming nothing else fry when you try it.
There is probably not much in it, except of course for the greater number of chips favouring the 162 chip systems. The 162 chip miner with 12v across the 18 Chip string gives a core voltage of 0.667V The 162 chip miner with 12.2v across the 18 Chip string gives a core voltage of 0.678V The 135 chip miner with 10.12v (measured by J4bberwock) across the 15 Chip string gives a core voltage of 0.675V A bigger factor may be if they have been selecting BM1385 chips, which of course we will never know? Rich The label I've seen on the Batch 8 boards states BM1385 + Anyone can confirm anything regarding older batches? So maybe hand picked chips, or a minor revision on the second batch from the foundry. 3 month after first release seems correct to have chips manufactured with a minor update on them.

Yes I wondered about the 1385+ label. You might be right and it is a chip rev? Something similar has been seen before on a 54 Chip board. I do not know which batch this was, but this label also has BIN2 which I thought might be a selection? Rich

Hi Everyone.
So normally I wouldn't rant about support topics, But I have 2 major issues I have been trying to resolve over the last few days with no joy.
Now I will start by saying bitmain have normally been really good and solve issues quickly, but I don't seem to be getting anything resolved at the moment so any advice would be much appreciated.
The first issue I have is that my latest S7 that is currently sat in customs has an invoice attached saying the value of the 1x S7 is $30,000 and they want £5000 for the VAT.
Now as far as im aware the S7 I ordered should be valued at $1650 but it seems that there has been some sort of admin error on bitmains side, I did receive an email from bitmain stating that we needed to pay our VAT or the machine would be sent back to them, I advised them of the issue and they sent over the correct invoice to me, but Fedex have request an explanation from bitmain and a copy of the invoice directly from them, so far fedex has not received a response and neither have I.
The next issue im having is with one of our current S7 machine from batch 5 has an issue, I checked all my machines the other day and noticed a very strong electrical burning smell and noticed 2x hashing boards had gone down.
I assume they have died but cannot check as there is a warranty sticker over the machine that I do not want to touch without the permission from bitmain, So far I have emailed info@ sent a message through zendesk and also messaged zendesk when live support was available and have so far received no response.
I feel a little ignored and for the first time in 2 years im annoyed at the way Bitmain is dealing with my issues, we have easily spent well over $30,000 with them, not much compared to some bigger miners but enough to think they would as least help.
Like I said I have been more than happy with Bitmain products and there support in the past, but feel very ignored at the moment, and any advice would be greatly appreciated.

Yes definitely Luck. My Batch 8 using the same 220V IBM 2KW won't change in hash rate by moving to 775 or 800M. Have to increase the voltage to see some gain like what Phillip did.
There is no point in changing the voltage on a Batch 6, 8 or 9. They have a Buck Converter built onto the Hash board that controls the voltage sent to the chips. Good news is that at some point I am sure a mod will be available that will enable the Core Voltage to be adjusted. Rich It's kinda good and bad news. It's good that there is a option someday there. But bad that we really don't know how long till someone mod's it. And with warranty I'm not sure how many will try during it or if after. It will be pretty obvious a mod on that if you needed warranty work. I will be more positive on it's possibilities after I see it being modded. Which I guess might not be that long depending on who is working on it.

Rich I have received a few replacement boards for a B1 with BIN2 label on the board but not 1385+.

The thing that really bothers me about the S7 is the new Bitmain warranty policy stating that if anything burns on the board, there is no warranty. It's likely that they wanted to avoid replacing boards overclocked/modded, but it also prevent honest users like you, who either got bad luck, or falling heatsinks (engineering failure) for example, to get warranty. I hope they will reconsider it, at least for the defects caused by falling heatsinks. If I'm not mistaken, on a batch 5, there shouldn't be any buck converters, unlike the 135 chips units. So the most likely dead components are an asic, a capacitor, or one of the small LDOs creating the communication voltages (usually 1.8v). You can start by shaking the unit to check if you hear a something like a heatsink that went loose. If that's the case, you can remove one fan without losing the warranty to confirm. You can try to negociate with them if it's a heatsink issue because there is no way they can take you as responsible for it. Other burnt parts can be caused either by a user overclocking the unit to death, or simply by one bad component in a batch, so it's a bit harder. If they are totally out of warranty, I'd be interested to grab one board shipped to France for experimenting.

It's fascinating watching you guys discus all of this. I wish I could contribute, but it's a good country mile above my head. Here's hoping a way to adjust voltage is found, since B8 definitely doesn't respond to increased 12V from the PSU as earlier batches do.
What is not known, at the moment, is exactly how this addition is being used by Bitmain. At one extreme it is just a Factory set fixed voltage used to make the best of the different batches of BM1385 at a given default frequency. At the other end of the scale the Microcontroller has connection to the System Controller and it's just waiting for a release of firmware to add adjustable voltage. Off at an angle from the extremes we have Cyper_BLC theory that it is a second layer of closed loop, safety based voltage control. Interesting! I'd toss my vote towards safety control--they have a financial disincentive to allow you to undervolt and underclock. Looking forward to having a look at the circuit they are using. If anybody looks can you post pics? Maybe that's already been posted pages back?

As a quick FYI, in my limited experience the bitmain PSUs are a good 5% more efficient than the 2000w DPS's.

Even though Bitmain's policy states no warranty for burned boards, Bitmain replaced 2 of my burned boards from B1 for free including shipping both ways. I didn't open the miner on my own, I emailed them that two of the boards don't hash. They asked me to open the miner and check the boards. I found loose heatsinks and burn marks. Turnaround time was less than a week after I mailed the boards.
