21  Alternate cryptocurrencies / Mining (Altcoins) / Re: EWBF's CUDA Zcash miner on: January 23, 2017, 07:09:37 AM
[SNIP]
I built the rigs frame myself, inspired and took ideas from alot of videos, images of others rigs owners, and a bit of my own ingenuity. For smaller frames you could think about building something along the way of https://miningcave.com/product/mc-buffalo-98-sk1/ the design is pretty nice and compact for a 4x gpu rig (they also have bigger one), you can also check the rigporn thread on this forum, gave me lots of ideas.
[SNIP]
thats what i've been aiming for as well, thanks for the hints.
your miningcave-link doesn't work for me (404) but i guess these aren't far from what you meant:
i am aware of the rigporn-thread as well but there is just too much noise in it Wink

anyway, before i'm further off-topicin' this thread:
ewbf 020 works nicely for me and its perfomance (excluding the dev-fee) is at least on par with nh-miner on my gtx9X0 cards and slightly better on my old gtx7X0 cards. it's been running rock-stable here and i like the face that i don't need to care about starting multiple threads per gpu to fully load the gpus.
i'd love to see some easily parseable stats returned (like: running/[...], submitted shares, avg. sol/s current sol/s, runtime, current diff, pool-url. in csv or json?) on some signal as i consider it cleaner than parsing output.
so my sincere appeciation to the dev for this nice piece of software!

cheers!

[SNIP]Ok so my 10 rigs are like so

6 x EVGA geforce GTX 1070 FTW Gaming ACX 3.0 - 8 GB (2x8pin power)
6x PCI-E Riser USB and powered version 006c (6pin power)
2x FSP Fortron Hydro G 750 - 750W
Intel Celeron G1820 2.7 GHz
ASRock H81 Pro BTC R2.0
Kingston SSDNow UV400 - 120 Go
HyperX Savage 8 GB DDR3 (2x4GB)
W10 anniversary edition x64
Drivers 372.19 but will upgrade to 372.33 today.

I choose dual psu rig because it doesn't take much more room, allow for dual fan cooling from below because i turned them toward the gpu's, more cables than solo psu so less money for added adapters, more power lines, more stable, consume less overall because able to hit the sweet 50% load spot that allow maximum psu efficiency, and cost 60% of the price of a 1300W psu, so money saved here too.

one psu power the whole motherboard and drives (mobo + ssd) all the motherboard added connectors for power of PCI are also on that psu, and 2x GTX 1070 + own risers + added fans
second psu power the remaining 4 gpus + their risers.

both psu load is the same (1% variance) and well splitted across all power rails.

Sweet spot running those rig is about 60% TDP (about 110w per gpus) and different overclock depending on algo, for equihash (zcash & fork) i used to run +150/+600 but with latest EWBF that exploit everything a bit better, i had to tone it down for stability @ 145/590, been stable all night across all rigs, for an added ~2.5% average more hash (~2585 > 2650sols/s) with Solver 0 and one EWBF instance.

@m1n1ngP4d4w4n: hi there!
i very much like your setup!
what kind of frame or enclosure are you using for your setup?
i am still planning a little smaller rig (aiming for 4 cards on 1 psu) but havent yet found a convincing way to mount everything together. will probably build my own frame, done it before Wink
23  Alternate cryptocurrencies / Pools (Altcoins) / Re: ZCASH / ZEC Suprnova Pool Stratum enabled: https://zec.suprnova.cc [PPLNS] on: January 02, 2017, 05:38:02 PM
allright, thanks for clarifying!

so far, i do like the pool, service and everything Wink

that info would be helpful on the website as well, especially the part of the threshold and the need for named nodes in order to be able to access any statistics.

i still seem to do something wrong here as i cannot see any statistics (all values empty) as before even after adding a '.name' to my address string. i guess the link to the anondashboard won't include the addresses '.name' extension, right?
mining on my registered account works fine so the problem shouldn't be on the software software-side here i suppose...

would it make sense if i pm you my address so you could check if you can find any balance/data to it in the system? be warned that i might have set that address also as payout-addr in my registered account...
24  Alternate cryptocurrencies / Pools (Altcoins) / Re: ZCASH / ZEC Suprnova Pool Stratum enabled: https://zec.suprnova.cc [PPLNS] on: January 02, 2017, 04:12:00 PM
hmmm, noone knowing what the donation is used for?
then i guess its simply some extra benefit to the pool-creator without any certain intent?

another one: the suprnova-website (-> getting started) states that anonymous mining is possible by specifying a (ZEC-)address as username.
mining statistics should be further available through https://zec.suprnova.cc/index.php?page=anondashboard&user=<address>
i've tried to do so but all i get is a dashboard-page where all values are missing even if i have submitted multiple shares before (no balance, no workers listed, empty histograms,...).
the address used also has not yet received anything so i guess there is a payout-threshold? if yes, how high is that, if no, how does one trigger a payout for anonymously mined ZEC?

again, thanks for your help!
25  Alternate cryptocurrencies / Mining (Altcoins) / Re: HOW TO SET UP OVERCLOCKING AND FAN CONTROL ON UBUNTU 16.04 FOR NVIDIA CARDS on: December 30, 2016, 03:06:03 PM

Nvidia Compute always drops memory to 2nd memory profile setting, which is legacy problem from the launch of 10 series cards.

You need to set up .sh overclocking profile that will add 404mhz (or whatever you GPU is short at) overclock to the memory to get the gaming memory performance of 8008mhz applied to the Compute tasks.  
thanks a lot for your reply! i'm not sure i understand you correctly what you mean by 'set up .sh overclocking profile'.
i assume you mean i need to create a bash-script (.sh) which gets executed during startup (just as you posted in you guide)?
this is exactly what i have done and this leads to the described behaviour in my case (level 2 (without clock-offsets) of a total of 3 levels).

without the RegistryDwords-option, the card is stuck in level 2 (of 3) right from the beginning.
26  Alternate cryptocurrencies / Mining (Altcoins) / Re: HOW TO SET UP OVERCLOCKING AND FAN CONTROL ON UBUNTU 16.04 FOR NVIDIA CARDS on: December 30, 2016, 02:19:38 PM
hi there and thanks for this writeup! pretty much covers what i've tried/observed so far.
besides setting coolbits to 28 (which i don't think is necessary as a value of 16 should suffice unless one wants to fiddle with GPU-voltages) i've also come across the xorg.conf setting of

  Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1

which ought to help set a performance-level where GPUMemoryTransferRateOffset can bet set which is in my case only the cards highest performance-level (can be checked with nvidia-settings -q GPUPerfModes -t)!

however, after booting the card seems to be in the highest perf-level but as soon as i start my miner the perf-leves goes back to the second highest level where the GPUMemoryTransferRateOffset cannot be set.
any idea what i might do wrong on this?  Huh

setting fanspeed and GPUGraphicsClockOffset seems to work fine as both are settable not only in the highest perf-level...
driver used on my debian-system is 375.20.

cheers!

EDIT: i have no clue how to choose ZEC-difficulty but know that typical video-card-ranges are somewhere around 64-256. can anybody give me a hint how to choose a good difficulty? i think i remember having come across some guide or article regarding this but simply cannot remember where this was and search-engines are of not much help either...

Usually pools adjust difficulty against your hashing power. Some pools allow you to choose it like flypool. A little guideline taken from zcash page on dwarfpool

128 for one videocard
512  for rigs with 2-4 cards
1024 for rigs with >=5 cards

cheers Smiley
right, thats what i roughly had in mind, thanks for confirming!  Smiley
sec.suprnova.cc also allows choosing your own diff btw.

i also remember that it was recommended to ideally have each node send 4-10 shares per minute to the server in order to reduce load on the backend which in turn should benefit the whole pool. 

now what i wanted to better understand is what happens in cases where my nodes often get new work assigned without having sent any shares since the last work-package was assigned. are the computations done in this timeframe lost (to my disadvantage) and would thereby sending rather 10-20 (accepted)shares per minute lead to a higher accepted number of shares?
according to my (unproven) theory, i would loose less work if shares are sent more frequently. of course this has not to be the case every 3 seconds or so but i've observed quite a few cases where new workloads were sent only 10-20 seconds apart from another...

thanks for enlightening me  Cheesy

cheers!

i recently joined suprnova's zec-pool and was wondering what the donation each user can select is used for.
looked around the site and couldn't find any info on this.

a donation based pool is an interesting idea albeit i doubt enough would be willing to donate to make up for a low/zero percentage of fee's but since there is a fair 1% fee on suprnova (with occasional 0% special's) i wonder out of pure interest what the additional donation would be used for.

anyway, thanks for the good work and support!

thanks @EWBF_ for providing us with this nice piece of software!
007b was running smoothly on my linux machines on stock clock-speeds (gtx 750ti, gtx 970, gtx980) and so does 008b (alas not yet tested with the 750ti) with nvidia driver 375.20!

running multiple instances on ewbf v 008b doesn't increase my sol-rate on any of the cards but rather decreases by 5-7%, have not tried that with 007b so i cannot compare.

what kept me wondering a bit however is that my gtx 980 is not performing too well compared to my gtx 970 at the same power-levels (150W) and difficulty (64).
running 2 threads on each yields to:
gtx970@150W -> 2 * 105 sol/s == 210 sol/s -> 1.40 sol/W
gtx980@150W -> 2 * 109 sol/s == 218 sol/s -> 1.45 sol/W

of course the gtx980 runs cooler and if i set a higher power-cap it clearly beats the gtx970 in sol/s reaching
 ~257 sol/s (@230W -> 1.12 sol/W) or
 ~250 sol/s (@210W -> 1.19 sol/W) or
 ~246 sol/s (@190W -> 1.30 sol/W) or
 ~236 sol/s (@170W -> 1.39 sol/W)
but has a considerably lower efficiency (sol/W) than my gtx970. as environmental aspects are a concern for me i wonder what may be the cause for the gtx980's weak efficiency. any ideas?

my gtx970 reaches even > 1.50 sol/W when setting a power-limit < 120W and i'm quite happy with that.

that maybe has nothing to do with EWBF-miner directly but never the less might be of interest for some Wink

ps: power-cap set and power-usage read through nvidia-smi

EDIT: i have no clue how to choose ZEC-difficulty but know that typical video-card-ranges are somewhere around 64-256. can anybody give me a hint how to choose a good difficulty? i think i remember having come across some guide or article regarding this but simply cannot remember where this was and search-engines are of not much help either...

Bitstamp Ltd. is located in Berkshire, UK but it is just a Ltd. which is not a sign of credibility as such.
While this is the businesses address i think i read that they were based in eastern europe.

I dont understand? Whats bad about referral links? Please explain.
referral links might be neither good nor bad. but joining when joining a community it might be wise to try to respect some rules.
the readme clearly states
Code:
Don't make threads or posts solely for putting up referral links, that's what signatures are for.
i may not have noticed that initially but i happily agreed once i learned...

i've so far had good experiences with electrum (which is a lightweight wallet but not a web wallet) and liked it for its simplicity and low resources.
with multibit the handling of multiple (independent) wallet seems to be easier but i haven't tried it yet as i was happy with electrum.

i would keep in mind that if privacy/anonymity is a concern localbitcoins.com seems to be the only way to go as all the other relatively trustworthy exchanges require you to verify your account by submitting high-quality scans of id's and the like.

i just registered with bitstamp and was rather surprised to find such strict verification rules:
Code:
To verify your account please submit

1.) a valid government issued ID, acceptable high quality images of documents are:

    international passport (double page)
    national ID card (both sides)
    driver's license (both sides)

2.) a proof of residency, acceptable scanned images of paper documents are:

    bank statement
    utility bill for utilities consumed at your home address
    tax return, council tax
    certificate of residency issued by a government or a local government authority

You can also submit other documents to serve as proof of residency such as; government-issued documents, judicial authority-issued documents, documents issued by a public agency / authority, utility service company, or similar regulated service providing companies.
Notice

To avoid delays when verifying your account, make sure that your submitted documents are:

    VISIBLE in their ENTIRETY (watermarks are permitted)
    images of HIGH QUALITY (colour images, 300dpi resolution or higher)
    valid ID documents, with the expiry date clearly visible
    proof of residency document must be a scanned image of a PAPER document
    proof of residency document must be ISSUED within the last 3 MONTHS and addressed to your NAME and HOME address
    NOT ELECTRONIC bills/statements, online screenshots, or mobile phone bills.

My verification was denied, what now?

Please check your email for the reason and re-submit a verification request with the correct documents. If you should need further assistance please submit a support ticket to: https://www.bitstamp.net/support/

download-page for catalyst v 11.12 with 2.6 sdk (both 64b and 32b available)

i thought 12.4 with sdk 2.7 should be fine as well, no?
and do you know if 64b mining-performance is indeed better than under a 32bit system?

cheers,

EDIT: err- hold on, that seems to be only the sdk... but what about dl-ing it from x-drivers (i hate 3rd party driver sites but well...)?

ah, i must have over-read that section. anyway, thats quite some serious identification going on there.

why not turn this thing around and demand an exhaustive explanation about what they are going to do with your data, who will be granted access to it and why exactly they can't proceed to fulfil their liability without you providing it.

or what about cancelling your order? just send them a written statement going somewhat like
Quote
herewith i'd like to cancel my order <ordernumber> placed <date> over <quantitiy> oz gold and <quantitiy> oz silver and demand the immediate refund of <price> BTC to my account <dirtyRandyBTC#> within the next 5 business days.
sincerely yours,
DirtyRandy
?

you can't force them to do business with you but if they refuse to do so you still can claim whats yours, right?

Contact support@inputs.io and you can claim a (partial) refund.

partial?

Everyone who has lost money will be fully reimbursed.

this didn't sound very partial to me  Smiley
