101  Alternate cryptocurrencies / Mining (Altcoins) / Re: Fourth alt coin thread last three got oversized. on: May 23, 2017, 07:36:02 PM
Anyone ever get that itch to buy mining gear?
It's about to kill me waiting for vega!!!

I know what you mean, I've been waiting also to refresh all my rigs. Space/Power is limited for me so I have to go with full density all the way. If Vega doesn't turn out to be all that, then 1080's for all my rigs.

I had a chance earlier today to purchase multiple 1080's from newegg for only $369 each, but passed on that deal because Vega is sooo near!

the 1080 ti's do a lot of hashing.

I am at the point  that I will do the katana build
with four of them  and then have all  3 card 1080 ti rigs.  which are about 2000 sols for zec  at only 550watts at the k-watt-meter
I may do a 2 card 1080 ti with a katana as it will fit in the case and stay cool.





Have you considered this case?

It took some custom mounts to place the cards like that. The hottest one is in the middle at 65C.
Thanks for all your posts by the way. Very informative and helped me out choosing parts.  


94 dollars - 15 rebate = 79

  i paid 44 for mine on sale

maybe I would get it.  what sapphires are in there and whats the watts pulled for the unit at the wall/




I had 2 in a case like yours and they were getting as hot as 75c mining zec a few months back + you can turn this HAB case into an open case rig by taking off all the side panels. There are some hdd cages on the lower level which can also be unscrewed and taken out as needed.

2 480's and 2 470's all 8gb. Mostly mining eth at 125.7 mh/s. Right now they are on zec with 1260 h/s.
Don't have a watt meter but gpu-z shows 80 - 90W for the 470's and 90-100W for the 480's. They are clocked high as power usage is not a concern. PS is a corsair rm850i

Windows 10 x64 ar fi de preferat. Pentru drivere pune 16.11.5. Versiunile 16.12 nu recunosc placile cu bios modificat (ai modificat biosul nu?) Cauta programul DDU pentru dezinstalarea driverului existent.
Apoi porneste claymore fara overclock sa vezi ce ai obtinut
104  Local / Minerit / Re: Salut, as dori si eu o parere :) on: May 23, 2017, 10:11:11 AM
Salut, as dori si eu o parere de la voi , am o sursa unde pot caza cateva aparate de minat unde nu platesc consumul (energie verde).
As dori sa investesc un maxim 2500 euro in asa ceva. Vreau sa stiu de la voi daca renteaza in momentul de fata sa mai incerc ceva.
Avand in vedere ca nu platesc consumul as dori sa cumpar aparate mai vechi care pentru altii nu mai renteaza. Vi se pare ok?.Multumesc

Iti poti face un rig cu 6 x GPU amd RX570/580. Ai avantajul garantiei componentelor noi + produci mai mult bitcoin minind pe algoritmul ethash/equihash. Nu am un calcul exact dar nu cred ca ai depasi bugetul.

Aparatele de bitcoin (s7, s9) sunt pretentioase, galagioase si consuma mult.  
105  Local / Minerit / Re: Setari pt rig de minat GPU ?! on: May 23, 2017, 10:02:24 AM
Si eu am garantie la ele. Cel putin la sapphire nu este niciun risc pentru ca ai dual bios + poti sa obtii peste 28 mh/s la 1150 gpu clock/2000 memory clock cu un consum de curent mai mic decat ai acum (observ ca sapphire e la 1306 gpu clock din poza de mai devreme).
La profitabilitatea de azi chiar ar merita sa incerci. Ale mele merg de 5 luni cu bios modificat fara probleme.

Din cate am citit ... daca ai in jur de 1000/minut e ok. Am 2 RX 470 care sunt in limita asta, una la 2150 (daca o ridic la 2200 pe asta apar milioanele + scade hashrate mult)  si una la 2200. Celelalte 2 placi sunt RX 480, la ele erorile sunt mai multe (de vreo 10 ori) dar par sa-si faca treaba. Iti dai seama daca ai ricidat mem clock prea mult atunci cand scade hashrate sau system crash.
Daca merge stabil, ineficienta provocata de erori ar trebui sa fie compensata de hashrate-ul mai mare.

Deci nu ar trebui sa iti faci probleme cu 2-3 erori.

Pai si eu cu 2 RX 480 la 2250 aveam in jur de 10k erori pe minut, nu imi fluctueaza hashrate-ul in miner dar cand vine vorba de pool, hashrateul calculat e mai mic. O sa fac o comparatie intre no memory errors si cum era inainte.

Ai bios modificat? Ce model RX 480? (eu am doar sapphire nitro+) Ce hashrate ai? Ar trebui sa scoti peste 60 mh/s din 2 placi

Toate pool-urile din cate am incercat au hashrate ma mic decat cel raportat inafara de dwarfpool (indica hashrate mai mare decat raportat majoritatea timpului + poti seta payout de la 0.1 eth, dar to sunt pierderi din diverse motive)

@vio99 incearca tutorialul. daca nu esti sigur mai bine lasa-le asa decat "prajite".  Scrie-ne si vedem cum le facem  Wink

Pe maine...

Am crescut frecventa la memorie pana la 2200 si a dat crash , la 2150 si acuma a ramas stabila la 2100 si merge. Ideea este ca nu stiu unde sa ii scad consumul din wattman si unde mai exact sa il gadil Smiley poate imi poti arata niste poze .. Cheesy As fi foarte recunoscator. Ms anticipat.


wattman nu e prea stralucit. Cauta sapphire trixx pentru overclock/fan settings si watttool pentru scaderea consumului.
Cum am spus nu toate  placile merg la 2200 dar 2150 ar trebui sa fie ok.
In watttool trebuie sa setezi offset. La mine -16 merge perfect.

Incearca HWinfo. La mine apar erori pentru e biosul custom si daca ridic mem clock prea mult am milioane de erori. Oricum performanta placilor e destul de buna.

Da. Cea mai buna solutie este sa modifici biosul existent. Nu download de pe net pentru ca sunt multe variante/tipuri de memorie etc.
Ai nevoie de polarisbioseditor si de atiflash.
Uite un tutorial bun https://steemit.com/ethereum/@cryptomined/how-to-get-30-31-mh-s-with-your-rx480-8g-amd-sapphire-nitro-using-a-bios-mod-for-ethereum-mining-xfx-msi-monero

Acuma nu il mai pistonez ca imi este frica ca se blocheaza si eu nu sunt langa el si e tarziu in ro sa mai sun amicu sa mearga sa il resusciteze Smiley dar maine o sa incerc Cheesy apropo daca nu e deranjul prea mare un id de skype ceva sau fb  sa mai vb sa mai imi explici putin Cheesy In privat Cheesy.

Ps: pe stock am hash-ul 122.5 Mh , cu ele la 2100 mem aveam 126.5 Mh Cheesy oare la 2250 cat o sa am Cheesy =)))

Cam putin pentru 5 placi. Eu am 4 cu 125.7 mh/s in mod single mining. Solutia este modificarea biosului. Nu e complicat si deloc riscant daca doar modifici memory timings. Cauta pe google modifying memory straps. Ar trebui sa obtii 145 - 150 mh/s doar din o modificare simpla.

Problema e ca la 2250 memory o sa ai multe memory errors si e contraproductiv + nu toate placile merg atat de sus.

You have a BTC address in your bat file. It should be an ETH address if you want to use dwarfpool.
Read Claymore's thread to learn how to set up the rest: best drivers, environment variables and so on...
