Topic: [ANN] Sfards:SF100, the first 28nm Dual-Mode Miner is accepting pre-order now - page 6. (Read 129578 times)

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.

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

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!

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, 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!

 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.

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

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

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)

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

future doorstops (note: knc jupiter 550gh btc miner on bottom shelf is off...is currently fulfilling the function of gravity assist device to keep workbench down)




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)

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 )

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.
