In Sfard's defense, it came out before any of the new chips.....

Only, it didn't "come out". Two, maybe three miners are reported in the wild showing dubious results - hardly the "mass production" they claim  Wink

There are a few more then 3 but not a ton.  They picked a few resellers and sold them 5.  It seems each one got that 5 number.   

After that purchase all quiet on front from SFards on chips or miners.  I think they must be mining internal is my theory.  They  have the only modern scrypt chip, so they have zero competition right now but old gear.
No, they have the only publicly announced modern scrypt chip. No doubt there are others with chips just as efficient if not more hashing away purely scrypt.
There is no way to know this.  Unless you know something the rest of us don't know.   

I think you are underestimating how hard it is to get a new chip, and cost.  For someone to do in house make a chip, then miner on scrypt for it is a pretty big task.

In Sfard's defense, it came out before any of the new chips were officially announced so they had no idea what they were up against - and you've got to start somewhere...  Even then they were just parity with what was already available (for a while), their SHA256 was equivalent to Bitmains offering at the time, and the Scrypt is equivalent to KnC.  The only caveat I would give is on the Scrypt side, since the KnC's aren't generally available (except used), but then you're paying a premium for the BTC side that's not that useful.  Then you have the challenge that it costs basically more than the InnoSilicon Terminator 110's (which are 2x the power consumption), and it was cheaper to just pick up one of those and a Bitmain S5.

The eco/save mode is interesting, but then the amount of money it can generate decreases proportionally, so unless you have very high power costs, it probably wouldn't make sense.

Hopefully they make a v2 chip and it's more current... Or blow out their existing chips so that it's cost effective to make something interesting.  Right now it's neither (IMO).

Hi, i have an SFARD and i'm testing it, but i found some issues mining at ghash.io:

1.- If i use it only as Scrypt miner, it goes at 1,5 Gh/s with 99'xx% error or rejects (no good bussiness). Why? if i would use it only as an scrypt miner, what must i do to run fine?
2.- If i use it dual mode, scrypt miner goes at 46-50Mh/s, but with a lot of errors or rejects (maybe 20 or 30%). btc miner goes much better, "only" 0.30% errors or rejects. What i am doing wrong?

I'm using a PSU cooler master V1200 with 1200w at 12v

thanks!

My only thing I can think of is try a different pool and see if better on rejects.   Sadly they did not ship many of these so no one really will be able to give  you good answers.

It was a very limited release.  Then company got quiet.

Hi, now it is hashing on f2pool with very good stats!

Theese are my numbers with this beast:

SFARDS SF100
SHA-256 is running 1450 GH/S and draining 770w "at the wall" (with a kill-a-metter), so its a very impresive 0,53j/ghs (and its not the save mode)
Scrypt is running 50,75 MH/S and draining 220w "at the wall" (with a kill-a-metter), so its another very impresive 4,33j/mhs (and its not the save mode)
total drain: 990w (with a 80+Platinium)

Very impressive, i'm very happy with it. Only one thing: It's very hot!

.53 w/gh is not very impressive at all...that pretty horrible for a "new" chip.

It is enough good for mining now and it have a "save" mode that drains only 0.31j//ghs, so i am very happy with this (and the scrypt miner have one of the best ratios, and it have another "save" mode).  Wink

Edit: it now run at 0.8v, and the eco mode is at 0.6v...  Shocked Grin

If I remember right I thought they said they ran best in one mode or another (sha-156 or scrypt) and that mixing you had more errors (or hell maybe someone else said it on this thread)

also my firmware on my titan was crap the first 3 months have they done any patches for your miner or was it just catch 'fishing' (you) and release (ie deal with our miner as is) ? If they have done no firmware updates for you ...well hell yeah ...ALL asic miners work on the release version of firmware (that will tell us a lot if there are no patches how much cred they have with these units)

Wish you the best of luck thou...keep us here informed

Sounds like when you think you're mining Scrypt only you're actually mining SHA256 and that's why your shares are being rejected.  Unfortunately, I don't know anything about the software that comes with the miner, so I can't help you there...

but yeah.... LTC difficulty is going up after halving....so there is 'new' stealth equip/chips out there someplace imho ......... we will be the last to know Smiley


 You're not factoring in that LTC price jumped a TON shortly before the LTC halfing - I'm pretty sure THAT is what drove some folks to turn lots of older, once-unprofitable miners back on - they're now PROFITABLE again, if only a little.

 My suspicion is that the original batch of SF100 units were so poorly designed at the board level that even SFARDS realised they needed to FIX it before they would be able to sell a significant quantity.



I personally own an SFARD and there is no issues with quality of the miner or performance I have had it running 2 months straight never had 1 issue with it. It runs like a champ. I even put my unit n loan to an editor and his review of the internals of the machine should be published soon.
That's at least refreshing to know they run well and do exist.  Now to get them at a reasonable price before too long.  Thank you for lending it for review there has been a veil of mystique about this miner for far too long.

ITOP Corp provides used Sfards SF100 miners on its official store

After halving though those prices are high.  Although I guess limited edition miner at this point so probley can charge what ever you want.

But really at halving they should have dropped at least 1/4 if not closer to 1/2 on price.   Unless it comes with the LTC it's minded since the day you got it.  Which would be a interesting sale.

Its a shame the chip has promise. Did anyone do a group buy thread for the chips.

So I'm guessing there is no update on those replacement board for the orbs. He is most likely very busy with his server power boards. When it's the second batch supposed to be released.

Likely part of it is SFards.  They dont seem interested in public sales right now they are very quiet.

So likely it's the same on chips that they are not selling at this point.  So those dev chips could be some of the few in public hands.   So it really could suck if someone spent a ton of time to design around it and then they the company with chips stops selling.

Its neither...they had huge issues with yield and board problems. LTC diff being where it is is simply the extra ALT scrypt hash that jumped on straight LTC after halving.

Good point....as a 'greedy' high end owner of two KNC Titan(s) that have ROI'd I HOPE you Sir are correct Smiley (hell its all about me I'll fess up) Smiley

but really board problems etc that I had not heard....although they always seemed to me to be a bigger deal as a sha-256 miner then scrypt ..er from the bulk chip sales
point of view...assuming they are doing such

but yeah shift from alts would be nice that means that LTC difficulty will 'eventually' flatline again and the Titans insane need to make them selves into doorstops will be
less about difficulty and more about their insane need to try and suicide (knc raspberry pi piece of crap 8th grade science fair project that they are) Smiley

but anyway......anyone hear of any big ass miners to make me less smug about the above and maybe weep a little bit and sob? I've heard zip...just the sfards supposed
maybe chips and something about innosilicon chips but that sounded (if i remember right) like 14nm vaporware for now

well it could be worse I could have kept the neptune orig order ...no way I'd be running a knc neptune for 10 months with btc difficulty ..so at least i missed that bullet
(and robbery) that knc diverted pre-orders for 4 months of those to the old knc swedish data hall)

so it goes

my setup if anyone is interested

You too could also be correct and the fact sfards waited till AFTER halving to really move any product seems to back your claim on quality issues.

Anyway ..just want it to flatline for difficulty (LTC) and rise in price (LTC) due to halving....(I got needs) Smiley

and IF it comes to pass some big ass scrypt miner farm comes to be or another data hall based mining chip solution for scrypt comes to pass .. I would at least like to
know about it ...rather then just look at difficulty on LTC and scratch head ...I will need a period of time to prepare for 'mourning' the demise of my Titan(s) to doorstop
status...would like the 'illusion' of control ..that at least I could see that semi truck coming to run me down a bit down the road .....rather then the suspense of wtf is
going on with difficulty and LTC. (hey its a pet peeve in reality it don't matter much what eventually will be ...will be ...but still ) Smiley

You're not that greedy, you got at least one of them dirt cheap.


yeah may be good to just get out of mining eventually ...I mean how long can 'dumb luck' carry a person..I mean I even got a BFL refund back of my 8.3k I mean 1 year and 20
days later but still Smiley Titans are going into their 12th month ..25 days or so and the supposed knc warranty is shot (like they even do anything anymore) Smiley

with mining done I can just let coinbase be my friend ....and then just yell and rant at price alone Smiley ah..blessed relief Smiley

I should do my next plan I call it 'attic mining' I have like 5k of crap I should sell on Ebay for $$$ and then just get BTC with it...if btc goes beanie baby I plop 2k into attic
put in better floor call it a rec room etc (partially finished) and my house value goes up and viola.....sideways 2x value (on paper) on house with rec room above the 2k and 5k i lost to btc say...... ..ie win/win even if crypto goes tulips Smiley .....but it sooooooo boring!!!!! lots of little stuff worth 20 bucks so much 'office space cubicle work' ...so I stall

but yeah that is the way to go.....worse case I get a rec room out of it .....less junk to worry about .....make the $$$ back on paper in house value anyway (frigging crytpo is on paper anyway as well I hoard it all)  and then could just despair on the 18k of asic equip making beanie baby coin Sad should such a catastrophe in crypto happen Sad

but think of all the coin i could mine if it wall went beanie baby Smiley (thats it embrace the denial!) Smiley

but on the other hand if crypto takes off in value again another bubble I'm really really gonna kick myself I did not do some 'attic mining' an move that 5k of crap into crypto! Smiley

(too much to do ...too much laziness) Smiley

Ah crypto ...all the enthusiasm of being an Amway Salesman ..with none of the security of at least getting a lot of Soap out of the process if it all goes south Smiley
