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

I don't think the S7 will keep anything cool with it's exhaust.  =)  The 2 box in my garage is raising the ambient TEMP of my garage by 14 degrees.  I do have 2 Ultra KAZE fans on the 2 x 2KW IBM PSU that do push a lot of air and the PSU runs very cool and those fans is powerful enough to push thru the PSU and keep 1 side of the S7 quite cool.   As Prelude said, would like to see the numbers after it's been running a couple of hrs as I'm definitely interested in seeing it as I have the exact same setup.

Cool is relative, of course - but the 45C exhaust air is fine for the PSU at the cfm the S7 so screamingly provides, especially at 60% (1200W) load. I typically run the bladecenter e psus in 2 packs like you describe, usually with 2x120mm 240v fans of whatever sort I can get cheaply locally...

I find the Avalon Reps selling Avalons very responsive and always willing to help both at Oregonminer and Zoomhash but that's a different topic.  Just a bit frustrating when you're trying to order more batch 8 S7s, their site was down for a few days, then it comes back online, after each Batch 7 box was $150 more expensive due to BTC increase.  Now the challenge with Batch 9 is if you're wanting to pay via Wire, you're paying $100 more per S7 vs BTC because they can't update their website properly even though support said it's fixed.  But as you say, due to the Monopoly, there's less concern about Customer service. I hope there will be more competition in the market so that all the vendors step up.  The only positive thing I have to give to Bitmain is that their shipping is super fast!

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.

I won't have access to the S7 for the next 8-9 days, but I'll definitely change the 6k8 resistor as soon as I'm back.
800MHz, 5,3Th is still too low. I'm sure we can do 900.
And I'll probably try to get an earlier batch with 162 chips later to see how it can be overclocked.

The batch 2 I have goes to 631 freq and it is rated 575 freq

I am using your 2880 watter with  12.2 volts  lots of overhead as I am running 1 miner on it.

but even if I do 12.5 volts  I top out at freq 631.

So batch 2 has some type of restriction

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?

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?

Where do I get M Miner Monitor from ?

Thanks

The app only goes to s5 with auto naming. You can stick the s7 in there but I never paid attention to it until you pointed it out.

Yep discontinued. Such an excellent app. Been using for years.

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 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.

Great, glad you got it. If you need someone to vouch for my character just ask dmwardjr sir.
