Avalon 6 Vs Antminer S7, which one you will choose?

[philipma1957]

With an 18-chip string, Avalon estimates about 0.26W/GH chip-level and BM1385 0.22W/GH chip-level at 0.67V
BM1385 estimates 0.18W/GH at 0.6V, which translates to 10.8V in; that's about a 20% reduction. If we can see about 30% reduction at 560mV that's around 0.15-0.16W/GH at 560mV (10V in); if the Avalon curve has a similar shape but shifted to slightly higher power (0.26/0.22) at 560mV you'd see around 0.18W/GH chip-level.

Assuming you can still run half the stock frequency (around 51GH per ASIC) at that voltage, you'd see about 25GH and around 4.5W per ASIC, for 1.8TH and under 350W machine-level with 10V rails. I'd be surprised to see under 700W for 3TH off that machine but I could be wrong.

but for the sake of argument lets say you do 1.8th  using 375 watts  my psu could drive 2 avalon 6's  easy  giving me 3.6th and 750 watts

so while the avalon 6 does not look great at stock numbers merely good.

  it looks great as an underclock undervolt monster.

reminds me of undervolt underclock of gpu's back in 2011 and 2012

I want these machines.

BTW the s-7 does not allow under volt below 11.7 volts now that was with the batch 1 controller maybe the batch 2 controller or the batch 3 controller allows for it.

the later s-5's allowed for undervolt

If you get 1.8 for 375 that would be amazing.  The 4.1's were monsters as you put it on underclocking.  If the Avalon 6 can do this  it will be hard to beat.

I mean even at having ... unless something huge changes 1.8 for 375 I think will make it still a valid in many places... which is huge.  So I'm excited to see it.

The Avalon6 will have much better downvolting capabilities here, as we were told some hours ago. But it is going to need adjustable PSU or buck converter. I'm not sure how much efficiency we'll be able to gain but just down clocking. Maybe not much at all, but we'll see.

On 4.1 it was a good amount.  So that is what i am hoping for.   I love my 4.1's and still run them today.

If Avalon 6 has same capability as them I will love it and want one at least.  Depends on how much that underclock is.  The insider seemed to make it sound like it has a good capability on it.

he said it was string which means you need a psu that provides 9-13 volts or 10 -13 volts
there are not many but they do exist.

https://www.trcelectronics.com/ecomm/pdf/rsp1500.pdf --- I have this  should do 2 units each at 375 watt 1.8th

https://www.trcelectronics.com/ecomm/pdf/hrp600.pdf  ---- I have this should do 1 units at 375 watts 1.8th

https://www.trcelectronics.com/ecomm/pdf/hlg600h.pdf ---- I don't have this. I would like to think it runs 1 unit at 375 watts 1.8th

I am basing on guesses 0 facts

 I am willing to get 1 avalon 6 to test on the above 2 psu's that I have.  As .18 to .22 watts are possible.

There are actually quite a few "variable 12V" power supplies around, but very few of them are anywhere near Gold efficiency.

 The ability to undervolt this design would make it noticeably more viable long-term, especially after the block reward halfing puts a serious hammer on profitability for ALL miners and renders most of them unprofitable at any electric price greater than "free" - but the only price I've seen linked for it still makes it unviable unless you have VERY VERY cheap electric.

 Speculation on actual numbers though is problematic 'till someone actually TESTS the thing.

 Also, the only quoted price to date has changed to $1400 - which makes this thing even LESS likely to RoI, unless you believe the current surge in Bitcoin pricing is going to turn stable (I do not, having done a bit more digging into that MMM scheme).

I suspect that there will be SOME sales of this machine just because Bitmain availability on S7s has been "sold out" for most or all of the last 2 weeks, and looks likely to stay that way for a bit.

True I can see a 10 piece group buy as the minimum. If we knew it did 10 volts and say 1.8th at 350-375 watts.

I wish they would send me a test model. I would pay for it  and test for the rest of us.

Depending on price and date I could be interested in a GB.   I really want a Avalon 6 to play with. I have to be able to justify it though.

I'm hoping we see more about it the closer it get's to official release.   The underclocking is what I really want to see.

yeah price is key...keep looking ...heard a group buy price (plus 50) of 1350 which seems high..but not sure how legit it would be or even close for 1 unit

(sits on hands)

prob won't buy anyway...but fun to watch from the sidelines (13c kwh here would have to be a hell of a deal )


edit: my guess is 1600 usd for individual unit....

kilo17 's 25 pieces come in this Friday  I hope.
I will post here and on the other thread. When they do.

The group buy holds some promise but I have a lot of hosted gear.  I don't want too much more gear hosted.

[madmartyk]

ZoomHash has them for $1449.99 shipping next week.

ZoomHash has them for $1449.99 shipping next week.

Andddd I am thinking about it! That's what I was looking for an easy single purchase not a MOQ or a group buy pain.

Isn't Zoomhash currently at the center of a lot of legal and business drama?

At their checkout, you can use a credit card or Paypal. I guess this would be enough protection.

I have never had an issue ordering from them.

[QuintLeo]

My only issues with Zoomhash are that their warrentees tend to be crazy-short, and they tend to be pricey....

[philipma1957]

They sold me five - six k in gear.  Some sales were good.

I am waiting for some info from kilo17 I may end up getting two or three from him.

[QuintLeo]

$50 or some such - like I said, pricey.

[Finksy]

I had a commitment from ZH to buy a large amount of hardware from them and arrange shipping myself (since I'm in Canada).  After making arrangements with a freight company, they backed out of the agreed upon price, 3 times at 3 different increasing prices...  Left a bad taste in my mouth, especially after the person I called on the phone to bring it up with essentially laughed at me saying oh well, we still sold them.

Yeah I think I will take another route or just wait with this miner, they don't seem to be the company I want to send funds to and hope it works out.

I've ordered a used S3+ from them that had a bad board within a month, and they shipped me a new one free of charge. So far it looks like the easiest option to purchase 1 miner, other than a group buy.  I'm still holding on to my 4.1's though until it is proven what the noise level is on the 6.

[madmartyk]

I bit the big one and bought 2 of the Avalon 6's.  Really hoping they ship this week as promised.

Would you happen to be willing to measure the sound on them and let us know how loud they are?

Would also really appreciate an update as soon as you get them in regards to the sound output, is there any information out there regarding the dB these output?

[alh]

As to sound, I've heard "Somewhere between an S3 and an S5 for loudness". Take that for what it's worth.

[madmartyk]

Just got a note from ZoomHash that my 6's have shipped!!

[truckinusa]

So...Is ZH the best place to buy a single avalon 6?

[Blockhunter]

seems like you loose factory warranty?
Could be a downfall if this is so. ...
