I thought i would be getting in the 400 range after looking at this link. https://en.bitcoin.it/wiki/Mining_hardware_comparison

if you scroll down to the 7870s they are all showing in the 400+ range.  one entry is actually my card.  I have the MSI R7870

If the drivers dont work just try testing the 7870 by itself first to make sure its not a dud card
should be getting at least 350ish
400+ will require overclocking

I did install my card drivers...i have tried 13.1 which is the latest released and i have tried 13.3 (currently) which is the latest beta release.  Did not see much of a difference with each.  I will download and try 12.8 now.

I just started mining and have been using my computers 6870.  Everything has been working pretty well and i have been getting about 300 Kh/s.  So i went to the store last night and after a bunch of research i purchased a 7870.  it was on sale and i saw online that people were getting hash rates of about 400-450 Kh/s. 

After installing my brand new second card i started mining, and the new card just will not perform!!!  i cannot get more than about 275Kh/s.  I searched and searched last night for hours trying to get this going.  I tried different thread concurrencies, intensities, pools, i updated the drivers to the newest version, as well as the newest BETA.  I DO NOT KNOW WHAT TO DO PLEASE HELP!!!! haha

Any suggestions?
