Title: Video Cards Flags and low mhash rates?!
Post by: Trini8ed on April 29, 2011, 04:47:00 AM
My groups currently has these cards we need to know what flags we should use and why the 4870x2 is so low compared to the wiki would like a fast response!

gtx 470 "What flags should i use"
4870x2 "What flags should i use" "Instead of being 180 in the wiki it gets 50+50 which is really low"
4890 "What flags should i use"
5670 "What flags should i use"
5850 "What flags should i use"

Hope for a quick answer and will be much appreciated.

As for the 4870x2, what is the command line being passed now? Is the gpu throttling itself due to thermals? I remember they weren't the coolest things...

Not sure about the 470, but the 5670 and 5850 should probably just be using -v -f whatever and -w 128

The 4870x2 gets to 41c under load using a custom cooler so cooling is not an issue any other reasons why as of now it has no flags and its being used in the gpu gui.
