Hi folks.

Im really pretty new to the bitcoin community, but as my experiencie as linux advanced user, i think this its quite disturbing
first of all, some data:

CPU: AMD Opteron 1810, 4 gb ram.
PSU 500 W

Now, the problem.
If i run a cgminer (i tried with 2.61, 2.2.1 and 3.2.1) and run a benchmark, i got around 118 mh/s. Litecoin the same.
The weird part is, even i configured a current peak of 960 and 1445, it only goes up to 500 and 1200.

You see?

Im using SDK 2.8 and catalyst 12.10.
If i run this aticonfig -pxl i got that:
PowerXpress: Integrated GPU is active (Power-Saving mode).

Even if i run aticonfig --px-dgpu i got no answer and the card still on that mode.

So my options are as follows:
-Defective card
-Bad driver & SDK combination
-Uhm?

Strange thing, if i plug a 4770 and boot up the computer, it makes one beet and get the POST. If i put this one, the server tries to booth several times until i got the beep and get the POST.
Its and headless server, so i dont know if i should configure something.
Thanks in advance!
