Title: Hash Rate? Post by: rizzler on October 03, 2011, 08:55:27 AM 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 ?

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. Title: Re: Hash Rate? Post by: Lord F(r)og on October 03, 2011, 10:49:30 AM CF is not necessary for mining, on some systems it's even hindering.

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) http://event.msi.com/vga/afterburner/download.htm 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? |
