post a screenshots of the worker windows.
It it possible that the different Chipdesign of your GPUs ( Vliw4 and Vliw5 ) cause that prob?

@ check_status, a stock 5770 produce ~180-200mh/s.

Which SDK are you using?
Which Catalyst drivers are you using?
Which Miner are you using?
Which OS/Version/bit are you using?

The 6850 can get 240-250 MH/s with 850-900 engine, 300 memory.
I don't know about the MH/s with 5770.

SDK = I'm not so sure
Catalyst = 12.4
Miner = GUIminer
OS = Windows 7 Pro 64 bit

and yes, I am setting my GPU1 to 1 worker and my GPU0 to another worker.

Guiminer?
If yes, 100% for shure you forget to set "miner1??" to GPU0 and "miner2??" for GPU1.
Guiminer cannot set it automatically.

Hi,

So today I bought a 6850 Sapphire. I got another 5770 Sapphrise.

6850 = 201mh/s
5770 = 188mh/s

Both cards are not overclocked. Running both should get me ~390 mh/s but the thing is that when I run both, my mh/s drop. My 6850 drops to ~140 mh/s. I use that card as my primary, meaning that I got both my monitors connected to it.

Running it alone is fine, but running both makes it drop to around 140mh/s.

Any help?

Thank you!
