post #3651 of 22522
so i set up 4 7850s mining. the 7850s are getting like 280 k/hash. This is about 100-120 lower than the litecoin wiki hardware chart says one should be getting. Also, on guiminer they will only run on the 7850 low setting, if I try the 7850 high setting it just errors out.


Any suggestions?

That's about what I am getting 290ish.  I think some of those numbers on there are peak numbers not sustained.

Can someone help me out? I am trying to add a third 7950 to my motherboard using a 1x to 16x riser. When I try to open cgminer it says it does not recognize the device. It is also not recognized using trixx. The fans are spinning and I even added a dummy plug to see if that would fix it. Anyone known how to fix it?

Is it recognized by Windows? Check the PCIe connector. Make sure the PCIe cable is not overlapping, other wise signals may cross and video card won't work.

If you can shield the PCIe cable with tin foil, then wrap it with paper to prevent short circuits.

Are you using riser cables? If so most likely bad connection or signal crossing across the cables.

Make sure you are running at the right settings and your display driver didn't crash.
