Do you mean just provide a backup pool? Or is there another setting?

When I am mining with 50Miner using CGMiner, on the 50BTC pool, it will show that it is still hashing (amount goes up and down) but I am not getting any new accepts. Going to the pool direcly shows that I am not connected anymore. What happened? Is there a setting I can add/change to prevent this.

Need to go to another pool?

Anybody else having problems with 50btc pool?  I will be mining and then my miner with still say it is hashing, but no new accepts are showing up in the log.

Thank you so much for the suggestions.

I will be mining for bitcoins BTC

What settings should I use for a HD7950 ?

Did anything fix the issue?

I am running a HD7970 and HD 7950 on Xbuntu but only getting around 360 kh/s

What can I change to help out

Here is my config file:

    {
        "url" : "http://pool.50btc.com:8332",

]

I get around 630 mhs with my 7970. Installed the Artic air cooler to make it run much cooler, the XFX cooler is not very good.

With Afterburner, can it apply the settings each time I start automatically?

Would a null video plug help? (DVI to VGA adapter with 75 ohm resistors in it to fake a monitor)

Is there a way to overclock individual cards?
I can mine with all three, but can only overclock the first one (probably because its the one plugged into a monitor)

I have a 640Watt Corsair PSU and was getting low hash rates with my 7970 (around 300mh/s)

I have two other 7950's plugged into PCI-e x16 slots.

The 7970 is on a x1 to x16.
This worked with on PSU, but the 7970 got low hash rates.
So I tried using another PSU to just power the 7970, but now it doesn't show up. The second PSU is jumped to run all the time
