kdyz uz se tu resi spotreby, tak tohle GULAZ zere 680W (4x1070).
A vykon presne nenapisu, pac jedu na nicehash a tam se to furt prepina, ale sedi naprosto presne (+3 az +5%) oproti whattomine.com

29-29,3MHs mi běhají Nitro RX570 4GB v rigu 5ks 650-670W

ROMANICAK: ale abych jen nemachroval.. u me osvedcenej postup na dvou rigach s ruznejma 580tkama - pres DDU smazat veskery GPU drivery, pak instalovat blockchain beta drivery, udelat bios mod, tzn memory strap pres polaris bios editor a hnedka kdyz das v claymore -benchmark 1, tak mi karty davaj stock 28,4MHs. Dal uz to muzes ladit jak chces. To co je dole na screenu mi funguje stabilne s hinyx pametma najednicku, samsungy mely pri tomhle nastaveni 30,5 a bezej stabilne druhym tejdnem bez prestavky.

ty blockchain drivery sou dulezity, kdyz sem mel standartni crymson drivery, nemohl sem se dostat pres 25MHs

ROMANICAK: Stavěl jsem rig s 6x RX580 Sapphire Nitro+ 8GB a všechny běží stabilně na 30-31MHs

ROMANICAK:
malo se snazis :) tohle je rig s nejlevnejsima 8gb 580tkama, hinyx pameti. klasickej bios mod a OC pres claymore. teploty sou ted vysoky, protoze nema pusteny vetraky pred kartama

SOONIC:
Hashrate mam 105 na 4 kartach, tzn. kolem 26+ na jedne. 30-31 se skoro nikomu nedari dosahnout. V diskusich jsem to parkrat videl, ale vzdycky nejakej jeden-dva lidi a ostatnim to neslo z ruznych duvodu (znacka/vyrobce pameti na karte treba). Ja se vys nedostanu, pak to bezi nestabilne - tuhne to, nebo (casteji) pametovy chyby, kdyz kvuli ethereu taktuju pamet.

Mimochodem - 30-31 na 1450wattu, to je rozpocitanejch 181+W/karta. Ja mam 670W a 4 karty - rozpocitano 167W/karta . Neberu ted vubec v potaz ostatni komponenty. Mereno wattmetrem ze zdi. Vychazi mi to dost podobne tim padem.

ROMANICAK: a hashrate máš vpořádku ? To jsi měřil wattmetrem ?
meanwhile někde na netu: I'm getting 30 -31 Mh/s per card on my 8 x RX580 Sapphire Nitro+. Rig pulls about 1450 Watts.

a jeste k SIA -
https://www.reddit.com/r/siacoin/comments/7p9ll1/summary_of_the_upcoming_sia_hardfork_block_139000/
For Siacoin miners, this will bring mining yields back to roughly the same level they were before the first hardfork on 2017-12-06.

Jeste k tomu napajeni riseru - FYI, ja mam tyhle. Napajeni maj nejakej 6pin, ale jde to pres redukci ze SATA stejnak. Mozna to funguje dobre diky tomu, ze karta si celkove vezme 90-110W (poladeno taktovanim a dalsima vecma) a ma svoje samostatny napajeni jeste 8pin (RX580) . Takze pochybuju, ze si bere celejch 75W ze slotu, spis to bude 50, ale mozna jeste mnohem min.

Kdyz se na to podivate pozorneji, tak vidite nejaky kondenzatory, civku, tranzistor, a jeden svab s 8 nozickama. To bude zrejme nejakej step-down menic nebo regulator napeti. zkusim zjistit co je to presne za svab a jeho specifikaci, ale dovolim si tipnout, ze prave diky nemu je wattaz zasadne omezena a tim padem s tim SATA napajenim neni problem. Karta si pak vetsinu vezme ze svyho pridavnyho 6pin.

VYHULENY_UFO: to je bez diskuze.

GULAZ: si myslim, ze uvidime na konci roku, kazdopadne na trhu s cipama pro vypocet sha256 je proste furt mezera a bitmain s canaan maji skoro monopol.

VYHULENY_UFO: jsem to smazal. Pac bych rek, to to budou spis pridavny PCIE akceleratory, ktery ve vysledku dopadnou stejne jako ASICy po konci moralni zivotnosti, tzn. poleti do kose.
Takze, pokud by cena nebyla vyrazne nizsi (coz nepredpokladam vzhledem k tomu, ze to je naopak dodatecnej HW i SW vyvoj), tak je to prast-jak-uhod proti dedikovanymu ASICu.

GULAZ: hele me se ptej, kazdopadne dragonmint uz je jistej, samsung se da predpokladat ze taky, s cipama ma bohaty zkusenost a bohata firma, stejne jako gmo no a tohle je otazka, protoze co by ne. vyvoj jde dopredu a kdyz ne letos, tak pristi rok treba.
vem si blby x86/amd64 procesory, co zraly pred patnacti lety a co zerou dnes.

PALEONTOLOG: s tou cenou mas pravdu, ja videl nabidky jenom okolo 2k usd a ted uz vidim i ty nizsi, tak to stoji za zvazeni. A Bitmain taky moc nemusim, ale nevedel jsem o alternative.

VYHULENY_UFO: pekny no, to jsem zvedavej. Od vydani S9 uz je to fakt dlouho a neco musi prijit :)

VYHULENY_UFO: pico

PALEONTOLOG: ja se tedka divam, jestli se da dohledat co v tom je presne za chipy, ale delaj to na nejaky samsung technologii 10nm.

http://news.8btc.com/ebang-releasee10-miner-with-samsung-10nm-chips
December 20 2017 Hangzhou-Ebang, the NEEQ-listed company based in Hanghzou, release its new bitcoin mining machine, Ebit E9 + + and E10. The DW1228 chips manufactured by Samsung 10nm process could boost E10 hashrate to 18TH / S. Almost one year ago, the Company release its 14nm E9 miner and shocked the industry.

-----
co je podle toho clanku ale husty, tak letos nas mozna ceka brutalni narust vykonu site a tudiz i obtiznosti, protoze na trh vstoupi dalsi vyrobci cipu. takze co natezis tedka to uz ti nikdo nesebere a za par mesicu budou vsechny ty s4/s9 v podstate k zahozeni.

Ebang emerged as the new player in bitcoin mining market, ranking the 3rd supplier in mainland China following Bitmain and Avalon(Canaan) with independent R&D capability in the market.
Bitmain and Canaan are well-deserved leader in bitcoin mining market in the past two years. However, due to the soaring price of bitcoin this year, mining business has become so lucrative that many companies are eying on the open market.

In September this year, Japan’s Internet giant GMO announced that it invested 320 million USD into the field of bitcoin mining. GMO plans to develop its own mining chips. In the latest press conference, GMO announced that the design logic of its 7nm chip has been completed and mass production in May 2018. In addition, GMO also plans to manufacture PC motherboards with ASIC chips and sell them to the public. Each compute card provides hashrate projected at 8T / s and consumes only 300W.

In November, BtcDrak, the anonymous contributor of Bitcoin Core, said that the Halong Mining Company released the new mining machine, the DragonMint 16T, which is said to be 30% more efficient than the AntMiner S9.

On 22nd this month, South Korea’s ETNews reported that Samsung signed a contract with Russia’s Bitcoin mining hardware manufacturer Baikal for the supply of 14-nm chips dedicated to bitcoin mining. The sample has been tested and is expected to be mass-produced by January 2018.
Bitmain is said to have become the biggest buyer for IC in December 2017, surpassing Hisilion of Huawei.

With deviation on AI, could Bitmain retain its leading position in bitcoin mining?

VYHULENY_UFO: jo, sam cumim na ty e10. To je ale raketa. E9 za cca 1100usd.

Trochu jste me donutili se zamyslet na tou spolehlivosti.

PALEONTOLOG: vetraky zkurveny.

CHILDINTIME: cena e9 z fabriky je adekvatni, z druhy ruky mnohem lacinnejsi nez s9. Bitmain me sere monopolem a podporou bch.
Na dragona by to stalo za to se slozit, ale na to zatim nemam. Treba se to zmeni :)
Asicy jsou hlucnejsi nez gpu, to spis do sklepa nez do bytu.
