Hi guys,

I have 2x 1200W common slot PSU that I want to use on the same mining gear.

I have similar things in the past back in the early days of overclocking over 15 years ago and back then there were some things to do to get this running correctly.


Specifically:
* Do I need to connect the grounds from each PSU together? or is that done automatically through the hardware (MB, GPU's, etc.)
* Same question for the 12V, should I connect the GND and 12V lines together through a couple of 6 pins connectors. What happens if I do?

The goal of connecting 12V and GND would be to streamline what goes where, so that I don't have to really pay attention too much about how many GPU's should I connect to each PSU's. Maybe I am overthinking it, but I know some current is going through the PCI-E riser boards, and some through the 6-pin Power connect on the GPU itself. But what's the balance? that's highly dependent on the cards themselves.

from my point of view connecting 2 PSU together (linking 12's and GND's lines) would be ideal - though the question of much current will be going through the "bridge cable". If that's too risky (through cable), why don't manufacturers of PDB/Breakout boards don't do DUAL boards with all the linking done through the PCB where it's a lot easier to get through high current?

thanks

Hi
I've got a few block erupter miners that need the stratum proxy to run - working fine.

I've had some strange discrepancies in the hash rate of my avalon 200 clone (which uses cgminer) between local hash rate and pool rates (tried a few different pools).
Anyway, I've got no high hopes in this "idea" but if possible I'd like to try to see if it makes any difference.

So, is it possible to configure cgminer to connect to the stratum proxy hosted on a computer on the same LAN?

thanks

Hi
I've been mining on the btcdig pool for some time using some block erupter blades with no problem; i.e. hash rate reported by the pool for each miner is spot on.
I just installed a avalon 200GH/s clone (with the openwrt interface) and while it is apparently hashing on spec at 200GH/s (I even tried overcloking it to 230GH/s with apparently no problem), the pool is reporting a hash rate of only 150-160GH/s.

I tried adjusting the difficulty which didn't change anything - I waited several hours in between each change to make sure I was reading a correct figure.

I am not sure what I am missing here, could it be a limitation by the pool?

Any help is appreciated, thanks!
