Hi, I'm wondering if Ethereum has (as Bitcoin) a hash of the rewards given by every mined block? or how and where will be registered those 5 new Ether each time a block is mined?

Cheers

Sorry, wrong forum. Please delete this question.

Hola, ¿Ethereum tiene como Bitcoin algún hash de las recompensas que se dan por cada bloque minado? o ¿cómo y dónde se registra el ingreso de estos nuevos 5 ether cada vez que se mina un bloque?

Hi there!

I'm building a mining rig (wheter it's profitable or not), my specs are:

Z77A-GD55 (Mainboard), Core i3-2100 (CPU), Corsair Vengeance 8GB (RAM), 500GB Sata (HDD), and now the problem:

I have a generic "500 Watts" (PSU), with this one, I'm pretending to supply the mainboard and HDD.

So far, the CPU works, it turns on and everything is working as expected.

The problem is... that 1st PSU won't be able to supply the 3 GPU I have (PowerColor R9 280x, Sapphire 7970, Gigabyte 7970).

So, AFAIK, I can supply those GPU with a different PSU in the 12V PCI connectors. So I buy this PSU ---> HP DPS-1200FB.

I asked before about turning on the GPU's PSU and then the mainboard PSU and there's no problem. In fact I can use a little relay to turn them both at the same time.

So yes, so far everything is OK.

But now another problem appears.

I'm using 3 of this usb risers, and now I'm not 100% sure of how should I supply them.

Some people says I must supply the usb risers with the 5v and 12v and both grounds (I mean 1 molex) from the mainboard PSU, and then only use the HP Server PSU to supply the PCI-6 and PCI-8 ports of the GPUs.

Some other people says I must get 5v and one ground from the generic PSU and 12v and the second ground from the HP PSU... to supply the mentioned risers.

I don't really know what to do, I'm afraid of damaging my GPU's. Is there anybody with experience here that can help me out?

Thanks in advance.

Hi there, I have a doubt.

Can I give 12v to a GPU (turn it on) before I turn on the mainboard? would that be a problem?

I have a Gigabyte 7970, and a MSI Z77A-GD55, I also have a generic "500 Watt" PSU to supply the mainboard, and a HP DPS-1200FB PSU; I'm wondering if I can use it to supply only the GPU.

Assuming that I can supply the GPU with that HP PSU; Due that those PSUs works separately, do I need to turn them on at the same time? or can I turn on the HP before the generic one?

AFAIK, I can use a relay of 5V or 12V connected to the generic psus 5v/12v rail... so, it will turn on the PSU at the moment I turn on the mainboard... but before I do anything and burn something I need to know if I'm right or how should I do it.

Thanks in advance.
