Do you need power raisers for Gpus to work?

I measured at the wall and was geting 700W with 3x 7950, so I think it can handle one more...

Hello,

I've been reading a lot in this forum and it's time to put everything I learn in to practice. The goal of this post is to help other noobs like me to build their own rigs. I never built a pc before so this is going to be my first time ... hope all goes well

Rig 1

This was my first try, I ask a friend of mine for help building it but the components don't work as I aspected. I can only put 2 cards working. Bought some 1x to 16x raisers but the system gets instable, or, sometimes it doesn't recognize the 3 board at all. Maybe I have to buy some powered raisers...

So know I have a system with 2 Gpus and a second computer with one more gpu. The fourth Gpu laying still
















Problems so far:

I think the motherboard is not so good, it doesn't work with raisers. So I'm going to try another brand...

Gpus seems great, I can get around 600 with a litlle OC ( Witch I don't know anything, I'm very inexperience...)

The case only has space to 3 Gpus. I thought it was more practical to have a case but I'm going to let go that idea. Even if you get a great case the temps are lower if the gpus are at the open and with space between them.

Ram seems to work and the Cpu also

The Psu was another disappointing. I search in the cooler master site for a Psu that could handle 4 HD7950 and this one came trough. The problem is that It as 4 connections to pci express on the Psu it self, but only got 2 cables with 2x 8pins and 2 cables with 1x 8pins... I wll take a photo later...
So I can only connect 3 Gpus to this Psu... Not counting on that


I Bought more equipment and will up date this post later today...

Any idea? I'm going crazy!!!

I tried bitcoin and every thing worked just fine but with lite coin I don't seem to get a connection to the server (any server)...

I'm sure it's something basic that I'm missing... Help please...

Thanks I didn't know that...

Hi,

I'm not computer Technic and I don't know nothing about code, so there are things a little confusing for me... Is there some tutorial on how to cpu and gpu mine litecoins?

I have been flowing the "get started" in the pool-x.eu but it doesn't seem to work... I follow all the steps but I´m sure I'm missing something. when I start the cpu miner, nothing happens. And when I try Gpu mining, I get an error saying that the openCl.dll wasn't found... I don't know what this means.

Can some one give me a hand please

I know this is not the right place to post, but I can't put it anywhere else...

Thanks

Thats not exactly like that, I will pay around 35% if it's coming from US. Don't pay anything if it comes from another European country and if it's from china... Well, usually  don't pay anything, but it's a mater of luck even if I had to pay anything it will be a lot less then from US.

hi, does anyone know if there is any company selling asic in Europe?

It seems that every business is located in the US... The problem is that taxes for importing products from US is very high. I think china is cheaper so it could be an alternative... But I can't find any sellers there also.

Thanks

Thanks for your help

I know that changes are on the way, that's why I'm going to start with litecoin.

For now I just wont something to get me started, then if I like the way things are going I will invest in something more serious for bitcoin...

I believe that Litecoin have a great margin for profit so I'm pending between investing in hardware and buying some coins... Maybe both...

Let me just say, off topic, that this is a great thing. I just discover this world of virtual money and I'm very enthusiastic about it. This could be the answer for the world financial problems. No more control by governments and greedy bankers. Sorry if I'm offending someone ideas, but I live in Portugal and we are living in very difficult days. I'm tired to see average people paying for the greed of some corrupt politicians. It's revolting. It has to stop!!!

Thanks

Hi,

I'm new here... I have been reading a lot about bitcoin and litecoin and I believe that it's the future. So I wont to jump the ship

I'm going to start with litecoin because it's easy to get the feel of it... At least it seems that way. No big investements needed.

What do you think of the ATI 5970? I have read here https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison that it has a better performance than newer cards, is this true?

I'm on the market for a new graphic card, and my options are, a second hand 5970 (or other older card) or a new version one.

Can anybody help me please

Thanks in advance
