Topic: Adding second 7970 lowers hash rate of first (Read 629 times)
800 watt corsair.
950core and 1375mem lowered the second gpu to 500 and the first to 400. Same with 950 and 1500

What is your PSU?

I have been running a powercolor 7970 for a couple of months with a msi 6970 in the second slot (getting 610kh/s mining litecoin on the 7970). I just got a XFX 7970 back from RMA and decided to replace the 6970 with it.
Now I can get 610kh/s with the XFX in the second slot but no matter what I do the Powercolor in the first slot won't go much over 500kh/s. I'm using the same settings for both:
8192, i13, w256,g2,lookupgap2... etc. Clocks are at 875 core and 1375 memory.
Computer has 8gb of ram...
I deleted the scrypttahiti and scryptcaymen files in the folder... no luck.
Any suggestions would be appreciated.
Thanks,
Andrew
