Hash Rate?

[rizzler]

So, i have 2x 5870 i got a while back, at that time i did not have a big rig to put them in so i just put them in 2 older dualcore servers i had laying only. currently they mine at around 380-390Mh/s. I got a bigger rix that supports 2 cards from a friend and i wonder how much i would earn in hashing from putting both of the cards in it and running them on crossfire ?

CF is not necessary for mining, on some systems it's even hindering.

Ok great, so basiclly i can just let them be in seperate machines?

another question i have is how could i pull more Mh/s's from my cards ? can they hash faster then 370/s wich overclocking, if yes, about how fast can i push them? and how can i do this in MSI afterburner ? i just installed it on one of my rigs and when it opens it's blank, no info on the card and i cant change anyting. I eidted the CFG file to enable overclocking.

Basically yes, but energy efficiency would be greater if assembled in a single dedicated rig.

taking a look at https://en.bitcoin.it/wiki/Mining_hardware_comparison your performance is quiet good (when not allready oc'ed)

for MSI:
I had to install the latest beta v2.2.0 for proper functioning (blank bars)

did you edited exactly?:

EnableUnofficialOverclocking   = 1
UnofficialOverclockingEULA   = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode   = 2

but be advised:

-tweaking AB cfg will result in a mess if you're not aware of what you are doing!
-extreme ocing stresses your gpu and will result in lesser performance over time or sooner/later in a sudden death
-psu provides enough power?
