im cannot do two coins ate same time ?

Which coin can do more value if done separately? Can I do both at the same time?


I don't think there are any coins that are still profitable to mine with CPU, but you'll be definitely be able to mine with your GPU's
I think Ethereum is currently the most profitable to mine with GPU, but if you want to be paid in BTC and automatically mine the most profitable algo's I recommend you look at Nicehash's miner.

Friends

I have a PC with FX-8320 CPU and two RX-470 video card

Which currency is worth the most?

Can I earn more more if I mine the two at the same time or only one ?

Grateful

Amigos

Tenho um PC com CPU FX-8320 e duas placa de video RX-470

qual moeda vale mais a pena ?

Sera que eu consigo ganhar mais se eu mineirar as duas ao mesmo tempo ou mineiro apenas uma delas ??

Grato

Amigo

conhece algum site desse que colocar o processador e placa de video e e calcula quantos H/S faz em cada moeda?

Grato
Almir


Pelo pouco que eu acompanho, acredito que a S9 ainda é a melhor.

Seleciona ali a S9, a energia e faz os calculos: https://www.nicehash.com/?p=calc

0.4/mês, fora os gastos..
268  Local / Mineração em Geral / Re: NOVA MINERADORA ANTMINER S9 14TH/s on: December 15, 2016, 03:09:29 PM
Amigos

Como esta o ganho da S9 num mes? Chega a 1  BTC / Mes ?

E o Custo de Luz ?

Grato
Almir

E o preço?

2100 dólares o preço de cada uma, sem contar mais uns 600-700 reais na PSU.
Consome +-1470W, em um mês 1059kWh ou 741 reais em São Paulo.
14 TH/s hoje gerariam entorno de 1,06BTC por mês(https://bitcoinwisdom.com/bitcoin/difficulty) ou 2300 reais. Entretando 10 de Julho será apenas metade da recompensa, então 1150 reais por mês.
Então assumindo o melhor de tudo a máquina lucraria 409 reais ao mês e um ROI 18 meses(considerei o dólar 3,7).
Mesmo ela sendo tão potente, produzindo mais q o dobro em relação as outras e com um consumo praticamente igual, ainda sim não vale minerar no Brasil.

Dear Friends

What is the best coin to miner with eth and using claymore´s ?

I see a lot of people talking about the Sol / S, what currency is that?

If I put to mine two coins at the same time the eth mining will continue with the same performance?

Thanks

271  Alternate cryptocurrencies / Mining (Altcoins) / Re: my pc shutdown when im put the second rx470.. please help me on: December 14, 2016, 12:19:56 PM
Chronek

how im can calculate how many gpus my psu can support?
or
how im can calculate how many W the psu can support?

I am using two PSUs on the same pc.
On the second psu I just put the second video card

see the second PSU


Even then it was not supposed to work?

The  USB Risers Use less energy Huh

Thanks
Almir



You have 500W psu powering motherboard, pci-e and one card?
12V 16A can support only 192W
motherboard with cpu disk etc will take about 60W + rx series have tends to take more power from pci-e, so you shoud expect about 75W per card = 210W ....Not to mention that you powered one card external so add 100-150W more

Try motherboard to one psu, external pins of both card from second
(or just motherboard can not support that power draw from pci-e, you could try powered risers too)
272  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's ZCash AMD GPU Miner v9.1 on: December 14, 2016, 10:47:37 AM
no i retire overclock! in what topic  you tell this ?

Is the Sol Coin is better to mine than eth?

Dear ffthomas

This values ?

Just FYI: with Sapphire "ref" RX470 4GB cards I get 202-206sols/s using WattTool with 1200Mhz+1000mV GPU and 1750Mhz+950mV memory settings and -5x6.25mV voltage offset. Heat and wattage reduced significantly. I use 16.10.3 driver, Win10 OS, CZM 9.1 (-i 6) and all cards are connected with powered riser (6 GPUs/rig). You don't need to overclock the 470 to get 202-206sols/s.

im can miner Sol and Eth at same time ?

my psu is that


Thanks
Almir


Download WattTool and try to use the settings I mentioned in the previous post.

What type of PSU do you have? Did you overclock the cards or use modded bios?
273  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's ZCash AMD GPU Miner v9.1 on: December 14, 2016, 06:41:11 AM

Dear xxcsu

im dont have a Rig yet

in this video of youtube this man do the same thing
https://www.youtube.com/watch?v=QxIS4-jX_zM&list=PLwMMCTQvqoncwqXzVXalTIdDU--4tpasJ&index=34

And in this video below this guy uses the same motherboard that I'm using 5 directly video cards with extensors
https://www.youtube.com/watch?v=i9vodIZQZVg

the motherboard have 1 slot pci express 16x , one slot pci express4x and 3 slots pci express 1x

I'm using the motherboard itself that I already have

and im have a motherboard gigabyte 790A-DS3P that have one pci expresss 16x and another pci express 4x

the first video card are in pci express 16x, and the second video card are in the slot pci express 4x

im not have risers.. the video cards Are directly connected to the express pci slots

I put both psu just to test if psu's power failure problem, I did it only once to test

now im using only one psu.! my system have 8 gb of ddr3

im have two video cards sapphire rx470 of 4gb. see first page

in this page have the picture of my system (motherboard, gpu, psu, etc)

Do you think it would be better to use the usb risers instead of goddess directly connected in the express slotpci?

Directly connected to the express pci slot does not work?

thanks
Almir

I think your problem is power related , maybe some driver issue.

did you tried switching pci slots ? probably you can not , bc you are not using powered risers and have only 2 x PCI Express x16 on the motherboard and 3 x PCI Express x1 slots.

Build a system with 7 or 8 gpu , that is not that easy for a beginner , if you can not deal with 2 gpu forget that rig with 7-8 gpu till you learn a lot more about building rigs , calculating necessary power supply wattage . If you get a right motherboard , PSU , powered risers you can easy build a 6 card setup , but you have to spend some money Smiley


" What PSU up to 8 gpu´s will help me ? " - its depend on the gpu itself ... for 6   RX 480 / RX 470 you more than good with a 1200 watts psu, bigger is better Smiley

http://www.evga.com/products/product.aspx?pn=220-P2-1200-X1
http://www.evga.com/products/product.aspx?pn=120-G2-1300-XR

if you are planning to build or later upgrade your system for a 7-8 gpu setup i would suggest any of this PSU's
http://www.evga.com/products/productlist.aspx?type=10&family=Power+Supplies&chipset=1600+Watts
or you can use  same watt rated server psu with breakout board

- make sure you have more than 2GB of system memory at least 4GB
- make sure your set  min 16GB of virtual memory in windows
- make sure you have a psu that can handle the load
- you sounds like a beginner Smiley , so my suggestion is : dont use 2 psu , if you doing it a wrong way , you can kill any of your system components , ( motherboard , gpu , cpu , memory modules , hdd )
- don't use those adapters you have on your pictures , get a real psu !!!
- get at least 2 powered usb risers and try to switch those pci slots around
- don't switch to win 7 from win 10 , you going to have more problem

Change Windows 10 and put Windows 7 can help me ?

im have one pci express 4x and another 16x.
im not using usb riser now !!! it is a problem?
my motherboard is GIGABYTE 790A-Ds3P

see the picture


My PSU has no power cord for the GPU´S

I'm using adapters, see photo above

the problem can be the psu ?

Thanks
Almir

First. Uninstall AMD 16.12.1

Next install AMD 16.11.3

Then install msi afterburner 4.3

Set. Afterburner  at - 50 for under volt

Set power at -10

Set core at 1100

Set memory at 1600

Set fans at 75

Open eth. And let it rip

By the way your psu is really weak and sucks

Dear friends
I do not know what else to do. I'm almost switching windows 10 to windows 7.

I'm running this command and after starting the 7.4 claymores it keeps turning it off.

See the claymores command:
EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0x4FAd3e68CEc96AfbB0457B17A46fF6896EB57E40 -epsw x

I followed the suggsy8 guidelines and uninstall the driver in safe mode and installed a new driver

See the screens :




This is my PSU :




Does anyone have any suggestions?

Thanks
Almir







Agreed it could also be a PSU problem but I did have a PSU with a single 18A rail which was fine for 2 x RX 480 GPU.

As he mentioned he has used 2 power supplies one to power each card...

The problem is "Unsupported Overdrive version 7" which I believe is a registry issue.

Restart in safe mode

Use the Shift + Restart combination. Another way of getting into Safe Mode in Windows 10 is to use the Shift + Restart combination. Open the Start menu and click or tap on the Power button. Then, while keeping the Shift key pressed, click or tap on Restart.

What is the best Driver for Sapphire RX470 OC for windows 10?

Thanks

EVGA makes nice PSU's - their slightly expensive, but worth it.
But yes, your PSU is the problem here.

Suggsy89

How im can remove in safe mode?

and how im can disable crossfire?

==============================================

Xdragon , Which PSU do you recommend? I'll use for up to 7 gpu's?

The reason for the shutdown is from the weak PSU ?

Thanks
Almikr

This sounds like it is a driver issue! Remove in safe mode and re-install as administrator.

Reboot.

After that go to AMD Radeon Settings and disable crossfire if activated.
