4601  Bitcoin / Mining / Re: not that it matters but are block erupters using genuine or conterfeit FT232s? on: November 02, 2014, 12:33:53 PM
my block erupter is still running on my htpc which is fully up to date and presumably has that new driver. vista 32 bit.

i have it pointed at cks solo pool just for the hell of it.
4602  Bitcoin / Mining speculation / Re: As some of us enter Winter, here're some calculations on true cost of mining on: October 18, 2014, 02:23:38 PM
depends on you heating cost.. if you get heat cheap enough with your normal HVAC system you still lose money heating with old tech ASICs and/or GPUs.. just not as much. loss is loss.

I would lose money big time heating with my GPU and 65 nm ASIC stuff vs my geothermal HVAC.

So, I take this and a hammer to stamp it into steel? Sounds like hell of work.
Wouldn't I also need lower-case letters?

turn the letter sideways for lower case.

I would prefer to hand Josh & Sonny over the Reavers and let them try to talk their way out of that situation.  Grin

(Firefly fan here) pretty harsh, even for Josh.. he didnt scam little old ladies (unless they were a byproduct).

Sonny OTOH..

OTGH (on the gripping hand) they are slick talkers with zero ethics.. maybe they would make it out OK with management position in the Reaper hierarchy.

[on topic] BFL refused my refund on a 65 nm little single. shipped it 5 months late when it was basically useless. I forwarded that to the FTC.

The reason I made mention of RAID 0 is for the sake of cgminer.  Does cgminer [In a sense] put all my miners in RAID 0 [You might say] to allow for more chance of a higher "Best Share" score BECAUSE OF a better COMBINED hash rate.  At present, it's as if the miners are both solo on solo [One might say].  Will cgminer COMBINE THE MINERS in something like a RAID 0 to increase chances?  Or will it remain like you said regardless, "BestShare is a random event."  You did have a "but" in that sentence, when you said, "...but probability based." 

IF cgminer COMBINES my miners in something like a RAID 0 to make them like ONE PIECE OF HARDWARE, that would increase hash rate and no longer be solo miners on a solo pool.  That's what I meant earlier when I said, "solo on solo."  It may be it makes no difference what so ever whether they are combined as if they were one piece of equipment or not?  Not sure...

David

there is no advantage to running hardware in separate instances as opposed to combining them.

IE two miner instances, running separately on individual 1 TH hardware will have the same chance as 1 miner instance that combines the 2 one TH units.

IOW 2 TH is 2 TH whether its several instances or one instance. the odds are the same either way.

EDIT: con already replied I see. asleep at the switch as usual I am..

found my original block erupter 333 MHs stick and pointed it at your pool.

take THAT!  heheh

and yes I know, no one would be more surprised than I if it ever found a block before the heat death of the universe but I miss mining. and its on my HTPC that is on 24/7 anyway so I think I can afford the additional 2-3 watts and 1% cpu time just to smile when I see the ol' cgminer program in the task bar.

thanks ck!

What about submerging in distilled water?  Would that remove heat faster than mineral oil?

LOL do it, I always love jackass movie, but reality ones are the best.


distilled water may be non (or close to non) conductive, but it will quickly become conductive as impurities leech into it.

What you want as miners from a miner. For example Size, power hookup, Easy to use, lots of fuctionality? You tell us.

nice to see you guys in the mining scene Smiley

for me, a small time home hobbiest miner I would like something like this:

USB connections, multi platform software (or can use cgminer).

stackable, maybe with an ATX mounting layout (stack multiple boards in a standard ATX case to be cat/kid friendly).

individual units around 150-300 watts to easily use on non dedicated circuits, just add/stack boards to meet power capacity.

pcie power.
4610  Bitcoin / Hardware / Re: one antminer S1 + two bfl power supplies (fun) on: July 01, 2014, 10:58:53 AM
I have (had) 2 BFL SC power supplies. one died and the other never gave its rated voltage (sagged under load).

the only thing they are good for is the cables. cut em of and use them in custom cable adapters.
4611  Bitcoin / Hardware / Re: {BFL} Here's a LOOOOOOOOOOOOOOOOOOK at your Monarch! on: June 24, 2014, 10:26:33 PM
Captain obvious here. There's a problem in that picture.. water blocks should NOT be connected in series...only one asic will get useful cooling, the other will overheat quickly and probably fry itself or the board.

you dont understand water loops. take a look at SLI/xfire water loops some time.

I lol at the low hash rate and high error rate though. wonder how many watts that thing is drawing..

sooo glad I bailed the BFL ship after getting singed on my 65 nm gear.
4612  Bitcoin / Project Development / Re: A sneak peak at the future of Bitcoin Cold Storage on: April 17, 2014, 10:54:30 AM
about the life of the chip.. when I think "long term" I think 30, 50 years. as in bury it in the ground or something and my myself or my descendants dig it up  and can use this device alone, with no other info, and recover the coins (assuming the technology to read it still exists).

having it with a lawyer as part of the traditional estate isnt an option if youre hiding it from *everyone*

if Im reading the specs right, this device alone then will not be suitable without some external object (printed keys as a backup to the data in the chip say). or can all that info be in the device itself, perhaps some printed on a slug inside thats not visible till broken? but then how does the user get that printed slug inside?

just thinking on possible uses as the glass enclosure itself should last for centuries, even if the chip itself fails or the tech to read it fades to obscurity.

EDIT: CT scanners are not exotic tech; we have one in the office (smallish multi provider medical practice). they are (relatively) common nowadays. point being that if a CT scanner can read the slug or whatever the physical media is in the device, just having it unbroken may not in itself be a guarantee its not compromised.

So as you say, physical security is important too.
4613  Bitcoin / Project Development / Re: A sneak peak at the future of Bitcoin Cold Storage on: April 16, 2014, 10:30:16 AM
Just to quickly answer a few questions:

I The idea is that once your data is written to the NFC chip inside, you lock it permanently, and then to redeem the data inside you must break the device open to obtain the main password to decrypting the device NFC chips which is kept on the inside.

I understand most of this but one aspect is a bit fuzzy to me.

it must be broken to redeem. the password to decrypt the NFC data is etched inside in some fashion? on something that is not destroyed by breaking the glass but not visible or scannable (say by a CT scanner)?

just how unbreakable is it. I mean I can swing a hammer really hard Smiley could one break it "too hard" to the point the password is not recoverable? or the NFC chip is broken? or do you read the chip data before breaking it?  perhaps (brief) instructions should be somehow visible when looking at the thing by eye? 30 years from now it may not be easy to figure out what this is if a decedent of mine finds it with no instructions.
4614  Bitcoin / Project Development / Re: A sneak peak at the future of Bitcoin Cold Storage on: April 13, 2014, 02:57:22 PM
Im really liking this. no one will casually toss it out when going through ones estate.

reminds be of the data storage crystals from babylon 5.

a question, and probably a stupid one at that. its one time use and user programmable (right?) and one is not able to check the key without destroying it.  so when programming it is there a checksum or md5 or whatever to verify it took the key? sure would suck to transfer a fortune to it and have it wrong.
4615  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core (Bitcoin-Qt) 0.9.1 released - update required on: April 08, 2014, 11:54:40 PM
just to get this straight..

ALL bitcoint-qt versions have this bug, correct?

how does this bug get triggered? just by having the client running?

or do you need to click a payment link (or something external to the client).. in other words just initiating a transfer via copy/pasteing an address was safe?
4616  Other / CPU/GPU Bitcoin mining hardware / Re: GPU's lifespan before they die on: March 15, 2014, 03:31:45 PM
as falconfly said, keep the entire card well cooled and it should go years. use a good PSU (seasonic, PC power and cooling, antec etc). use filtered air if possible.

I have 2 nvidia GTX 285's that have been doing folding@home pretty much 24/7 since 2009. I did add arctic cooling accelero xtremes HSFs (3 92mm fans each) about a year in just for noises sake though.

my 5830 has been going since 2011 non stop with BTC back in the day, now scrypt coins. its stock. same for my 6870 although that got an artic cooling HSF too as thats in my daily driver rig an needs to be quiet.

all are overclocked and have been (sometimes - depends on the season and coin prices, or, with F@H, if there was a chimp challenge or other competition going on) overvolted to one degree or another.

Yesterday my 25GH/s Miner from Butterfly that mined at about 26,5 GH/s went down to about 21 GH/s, now i saw with bfgminer that 2 chips aren't working anymore. Any Hints on that?



Solution? Put in a fridge or outside in the cold... really... quality engineering is that.

You know something Bickski?  Your problem is that you don't know anything about engineering or you wouldn't be saying this.  Engineering has nothing to do with it, as this is a chip issue. 

no, its a BFL issue.

what other mining hardeware out there need to do this?

Here is an updated picture of my setup.
https://mycryptocoin.us/downloads/miner2.jpg
Ps: everything in that picture is possibility for sale for the right price(except for the movies & scales). PM me your price.

 I would be more interested in the APC battery backups than the BFL and asicmine stuff.

love the smoke detector. thats smart although it would respond quicker if it were above it all and  towards the rear of all that airflow.

Also, this is the "Pictures of your mining rigs!" topic, not the "Pictures of your bitcoin mining rigs!".

This is a 'bitcoin' section of the forum, for bitcoin mining hardware.
GPUs are no longer viable for profiting with BTC, so you are either stupid wasting money on power for your rig, OR you are mining altcoins.

get over it. these used to mine bitcoin, and already people are having a big-enough hissy fit over it to create a 'no-scrypt mining rig' thread for people like you

IMHO: that other thread is stupid. I like seeing GPU rigs regardless of what they mine. they are creative, home-made, and often finely tuned. The pictures of ASICs are just a shiny box in the corner or a half-filled USB hub (which is almost just as big a waste of money as mining bitcoins on a GPU)

wrong on the ASIC being just shiny boxes. have you seen some of the ASIC setups? clean wiring, creative cooling, modified ASICs etc

and the computer that currently runs my ASIC setup also mines LTC with a 5830 that used to mine BTC back in the day. so it would fall under both categories..
4620  Bitcoin / Hardware / Re: BFL Product Failures / Underperformance. on: January 19, 2014, 01:40:12 AM
Yeah, I ran the numbers on Thursday... our RMA rate is 1.27% or thereabouts.  50% of that is like the picture above.  So the real failure rate is somewhere under 1% of delivered units.


Josh, do you honestly believe anyone actually believes any words you say??

that said some of what is posted here is BS.

anyhow, here is my fail rate:

1 SC25 running stock firmware @ 31 ghs (thanks bfl) would go "zombie" repeatedly and get restarted in the 2 days I actually ran it on the stock PSU. normally runs flawlessly on the computer PSUs, was an an antec 500, now a seasonic 750. had it a month.

1 jally 5 ghs flashed to 8.2 ghs. PSU failed after 6 months. runs on the seasonic now.

bfl single was fine the year I ran it.

so: 33% fail on the PSUs (50% for the SC series PSU), more if you count flaky operation on the SC25 PSU.
