hey there, thanks for your posts trying to help
but unfortunately my edit account section unfortunately has no api key as you can see in this screenshot: https://imgur.com/a/BcVHk

btw do you know whats the best way to contact suprnova pools admin? I tried opening a support ticket on https://zec.suprnova.cc/ but this is definitely bugged for me, I tried like 20 times and every single time I get "Invalid captcha" error even tho I am 100% sure I am not missing the captcha 

hey dude, did you find a solution yet?

thanks for your posts trying to help, mate
but as you can see in this screenshot i just took right now, there is no api key in my edit account section: https://imgur.com/a/BcVHk
do you have any idea of what might be going on?

btw I tried sending a support ticket to suprnova.cc but its just impossible, I tried like 10 times and everytime I get a Invalid captcha message, even tho I am 100% sure I am not missing it

hey there everyone

I decided to use 2x sata to molex adapters to power my molex-powered risers instead of using those widely infamous sata to molex that comes with them.  What is the best option between these two?

normally I would say that the second option is the best, but for some unknown reason, the first option seems to be much more popular in my country's website similar to ebay. So, like always, I decided to accept my ignorance and ask for some advice  

whats up guys
I dont want to take your time so I will be brief:
Im building a 6 gpu rig with 2 psus. Is it true that If I dont use my primary psu (the one Im using to power motherboard and cpu) to power all my riser adapters I might damage my motherboard PCIE slots or even my gpu or psu? I didnt take that information into account when choosing my power supplies and now Im worried that my primary psu might be way too close to 100% load when powering all 6 risers in this rig  

alguem por favor me corrija se eu estiver errado, mas pelo que eu sei a regra para alimentar adaptadores riser em rigs com 2 fontes é a seguinte: alimente todos os risers do seu rig com a fonte principal que vc usa pra alimentar a placa mae e o processador, use a 2a fonte somente para alimentar placas de video

by the way I just found out these adapters exist:

using 2x sata to molex adapterts like this one to power my risers is a much safer option than using that regular 1 sata to molex that comes with it, right? Funny thing I didn't find anyone mentioning these 2x sata adapters on riser adapters discussion threads, and they seem to be really useful

Hey there everyone

Recently I bought a EVGA 750BQ  (https://www.evga.com/products/product.aspx?pn=110-BQ-0750-V1), with the idea of powering 3 gtx 970 g1 gaming which is an specific 970 model that uses 2 power connectors (one 8 pin and one 6 pin) instead of one. When we talk about power, I am totally sure that 750w is enough to feed them, but I am really worried about the power connectors.

The problem is that I just noticed this psu has 3 PCIE cables and 5 molex.  I was planning to connect each gpu 8 pin connector to one of these 3 PCIE cables, and I was planning to use  2 to 6 pin molex adapters to feed the 6 pin gpu connectors. Since the motherboard I bought has one extra molex connection I believe I would be able to solve the gpus power connectors problem, but  is this safe? In this example I would have to power all my riser slots using the infamous SATA to molex adapter that comes with it.

By the way I cannot plug the PSU in the 970s  and test it by myself because the motherboard for this system will probably be delivered where I live only after Christmas.

I really need some help here, because in case I find out that the PSU I bought isnt going to work I need to return it to the seller as soon as possible and buy one that actually works

gtx 1060 com memoria micron vc acha que vale a pena investir? dizem que sao melhores que as hynix, mas piores que as samsung

I know this is going to sound stupid, but can someone help me finding my suprnova.cc api key? I looked into all the options in the website and couldnt find it

hello guys
Recently I started mining some zcash on suprnova.cc and I installed one of those android pool monitor apps, however I really cant find my  api key, can someone help me please?

eu comprei sim, só que foi um baratinho que pra falar a real nao me passou mta confiança hehehe.  na realidade eu pensei em comprar um kill-a-watt mas dai li que ele nao funciona em lugares com voltagem 220, como é o meu caso
o que eu comprei foi esse aqui: https://produto.mercadolivre.com.br/MLB-770343028-wattimetro-digital-medidor-consumo-de-energia-2000w-110220v-_JM sera que vai funcionar?

eu comprei uma gtx 1070 evga SC black edition nessa ultima black friday da kabum, pra rodar jogos mesmo, e posso dizer que até agora ela se mostrou uma placa bem fria e silenciosa. Rodando os jogos mais pesados nao passa dos 70 graus e eu sequer consigo nem ouvir os coolers dela rodando dentro do gabinete.

A principio nao, Anderson. Como eu queria botar as maquinas pra minerar o quanto antes, e como to querendo evitar ter dor de cabeça nesse começo aonde eu ainda nao manjo mta coisa, fui pra solução mais fácil e prática pro meu caso que é o windows mesmo.
Agora, se eu conseguir botar essas maquinas que eu planejei pra funcionar e elas se mostrarem realmente lucrativas, como eu espero que elas sejam, caso o cenario esteja positivo, daí eu pretendo reinvestir os primeiros lucros em mais rigs de mineração, e aí dessa vez, com mais calma e tempo pra ler e aprender, eu pretendo possivelmente investir em maquinas com mais de 8 placas rodando linux

fala ai rapazeada

legal que tem mais gente curtindo o topico. Nos ultimos dias li bastante e dei uma acelerada boa no projeto
agora pouco comprei as ultimas peças pra montar 3 rigs, 2 com 6 placas e 1 de 8 placas (resolvi montar um de 8 pra testar e ver qual modelo eu prefiro, escolhi 8 slots devido a limitaçao do windows 10). Como os correios no final do ano é bem ineficiente eu acho que as peças só vao chegar lá pro dia 28-29.... Mas enfim, segue a config dos pcs

os 2 Rig de 6 gpus:
Celeron 1840 (eu li algumas pessoas dizendo que tiveram problemas usando celeron pra minerar, mas ainda assim resolvi arriscar pq paguei barato, qqr coisa eu revendo e compro 2 pentiums)
Asrock H81 Pro Btc
4gb ddr3
Hd 120gb 7200 rpm sata
2x EVGA 750BQ (750w)
6x gtx 970 g1 gaming

o rig de 8 placas:
Pentium 4400
Biostar TB250-BTC+ (placa feita pra mineraçao assim como a asrock h81 pro btc, mas essa aqui tem 8 slots PCIE e é socket LGA 1151)
4gb ddr4
hd 120gb 7200 rpm sata
1x Corsair 750w CS750M  e 1x  Corsair 850w CS850M
8x gtx 970 g1 gaming

Ja comprei tb os cabos riser (essas desgraças sairam mais caro do que eu imaginava mas blz rs), os switchs power, e os adaptadores add2psu pra usar 2 fontes no mesmo pc. O monitor eu já tenho, teclado e mouse usb tb. Sera que tô esquecendo de alguma coisa? 

No começo pretendo minerar quase que só Zcash e as outras criptomoedas que usam o algoritmo equihash, pois parece que pra geraçao 9xx da nvidia esse é o melhor esquema no momento. Alguem aí teria alguma crítica ou sugestao? Qdo as peças chegarem e eu tiver montado os rigs postarei uma foto aqui pra vcs verem como ficou

Por enquanto é isso

guys as you can see in the image in the end of this post, I used an online psu calculator to calculate how much energy my system would use excluding the gpus

the result pretty much surprised me: 125w for a pentium 6440, one sata 7200 hard disk, 4gb ddr4 and one kb and mouse usb. Is this correct?  

Taking this information into account, and considering that running the psu 24/7 at 100% load might not be a good idea, I think I should  get one 750w psu for the 4 970 gpus (around 600w), and one 850w psu for 4 gpus 600w + 125w drawn from the rest of the system. Am I missing something?

what altcoin are you mining? I was thinking about getting a celeron but decided to go for a pentium because i've seen some people reporting problems mining with the currently mining software im using (genoil miner) with celeron processors

you mean like this one? https://www.parallelminer.com/product/power-supply-kit-for-3-antminer-l3-plus-litecoin-miners-ltc-94-platinum-high-efficiency-200-240v/
I was considering the idea of getting one of these, but since none of the mining tutorials or forum posts that I read recetly mentioned this idea, I deduced that there should be a good reaso that explains why I didn't see anyone recommending one.

and by the way I am already making changes in the initial post mining rig setup: I found out that the g4560 processor for some reason doesnt work with the Biostar TB250-BTC+, so Im changing it for a pentium g4400
And a really nice user from this forum sent me a PM explaining me that i was wrong about the way psu power works. For example, a  1000w psu that has 80% efficiency at 100% load is actually able to deliver 1000w like its name suggests, the thing is that when its at 100% load delivering 1000w for your equipment it will be consuming 1200w.
That means that buying a 80 plus gold psu will always save me 5% power compared to the bronze ones. Now I think I will pick 2 750w gold plus psus instead of 2 850w bronze. But still not sure what specific models Im getting.

thanks for the contribution helios and philip

Not really, from the early tests I did yesterday plugging one of the gtx 970 on my personal computer, I was able to get 300 equihash (300 sol/s) mining zcash with 70 or 75% power draw on MSI Afterburner.  

I am not totally sure, but I believe that when I've seen people saying that the 970 draws 150w when mining, they are already reducing the gpu's TDP through afterburner, because from what I've read on technology websites the 970 running heavy games at 100% power can draw up to 220w.

Hey there everyone

I'm planning to build the following rig, and by the way dont worry about profitability I'm 100% sure its profitable where I live:

Biostar TB250-BTC+ motherboard (cheap lga 1151 with 8 pci express)
Pentium 4440
4gb ddr4 2400
HD 120gb sata
8x gtx 970 g1 (I know they arent ideal but I bought em for a really cheap price)
2x EVGA850 BQ (850W 80 Plus Bronze )

The problem is: the 850w PSUs are bronze plus certified, that means at least 85% efficiency at 80% load and 82% efficienty at 100% load, and after doing some research, I found out that gtx 970 gpus usually draw 150w of electricity when mining, and Im planning to connect 4 gpus in each power supply.
Im pretty sure that the psu that will be connected  only to 4 gtx 970 will be fine because they're probably going to draw around 600w , but I am worried about the other one that will be feeding power to  4 gpus + the rest of the computer (processor, memory sticks etc). The 4 gpus alone might use 600w or more, and I'm afraid that when you include the power drawn from the rest of the computer the EVGA850 BQ might not be enough.
There's this one guy who told me I shouldn't worry because he knows someone who uses a 1000w psu to feed a 5 gtx 970 rig, but I still dont know what to do. I would hate having to buy PSUs and then returning it to the seller because I did a bad job picking my rig pieces.

What do you guys think? Should I buy one EVGA 850BQ and one Corsair TX850M (80 plus gold certification: 90% eff at 80% load and 87% at 100% load) instead?

Thanks in advance to anyone willing to help and sorry for all the English mistakes, its not my first language
