New mining rig with Asus EAH6950 - Temps / GPU Core / Shaders Questions!

[ragingazn628]

Hey guys,

Just finished my first rig today! Woot!

Rosewill ARMOR
Rosewill 1000W PSU Bronze Cert
Asus EAH6950 1GB x 2 OC'd@ 920mhz (top) and 950mhz (bottom)
Sempron 145 Unlocked to Dual Core @ 2.8Ghz

Are these numbers correct?
Both with flags: -v -f 1 -w 128 BFI_INT AGGRESSION=13
Mhash/sec:
Top: ~380
Bottom: ~390

Temps:
Both 75-76C

First time mining I don't know what to expect... how many coins can this rig generate a day?

It varies with the difficulty level.  Right now you'll get about 0.3 per day.

How much money will I get each month?

About $30USD.

You can join a merged mining pool as well and try and cash on the extra NMC.

If this is a dedicated mining rig then run Linux and don't unlock the second core.  You don't need it an it just generates more electrical load.  I actually downlclocked my semprons to 2.0GHZ cutting 10W off the load.  Yeah 10W isn't much but every watt helps. I also turn off onboard audio, USB3, SATA controller, serial port, etc as well as downclock the RAM.  It all adds up.  I run 3x5970 and entire system draws 860W at the wall.

Now if you are running Windows (100% CPU bug) or this rig is used for more than mining then you might need the second core.

but how can I overclock on Linux?

[DeathAndTaxes]

Overclocking is easy.  Just use cgminer.  Overvolting is trickier and may require a BIOS flash.

[ragingazn628]

I have it at 20% more power in cataclyst also... that's overvolting i believe.

Do you think you could check whether changing the Powertune in catalyst drivers actually impacts your hashing speed or power consumption?
I have a few EAH6950 cards myself and although the driver reports success, the powertune value has no effect whatsoever on any of them.

As to how one overclocks on linux, along with the catalyst driver you installed a little utility called aticonfig which is able to change gpu/memory clocks or fan speed.

Alternatively, do as DeathAndTaxes suggested: cgminer is a GREAT miner (possibly the best?) and it integrates mining, overclocking and fan control in one neat package.

Yeah your right.  It has been so long since I used a 6xxx card I forgot about powertune.

I'm currently using GUIminer - is cgminer better?

[DeathAndTaxes]

cgminer is so good I won't even consider using another miner.
