Even tried 50Miner because it suppposedly automatically configures, but had similar connnection errors with it too.Īdditionally, whenever I restart/reboot the computer it will not recongize the OpenCL Juniper GPU. Have no idea why I am now getting such errors with GUIMiner. However, when I now have OpenCL Juniper recongized and try to mine with GUIMiner, it shows it mines at about 180 Mhash/s, but it keeps getting 'Verification failed, Check hardware' errors and when I swithch to OpenCL i7 CPU it shows 'Connnection error' and I can't mine with either. Don't have to load any version the AMD APP SDK ss now the APP SDK Runtime in Cataylst 13.1 and 13.3 work. The HP has updated drivers installed and the LG doesnt.Welll Madpacket's advice to unintall all ATI/AMD drivers and then delete 'OpenCL.dll' and 'amdocl.dll worked in the sense that now I can install either the most recent Catalyst official 13.1 ver or Catalyst beta 13.3 ver and have the OpenCL Juniper recongized for example on GPU Caps Viewer 1.18.0 and can now run the demos thereon. One monitor is HP VS15 and the other is lg 20ls7d, and both work with the vga output from the onboard graphics. Also changing the primary video adapter in the bios seems to make no difference.

Strange thing is, the driver installation detected the card and installed the correct software but windows device manager doesnt detect the 5770 (also tried disabling the onboard graphics in device manager, no luck). I have tried plugging into both DVI outputs, with and without the vga adapter to different monitors, as well as both HDMI (although the HDMI cables dont fit in completley in because they hit part of the case, this shouldnt affect the DVI output regardless?) the built-in vga output works ONLY when the 5770's power is unpluged durring powerup, then plugged in after which was how I installed the drivers.

There is also an option for ' PCI express Graphics port setup' to X16 or X1 (this has been set to X16). Drivers were installed and primary onboard video bios option was set to PCI (there is no option for PCI-e) from onboard. Opened a new 5770 card and installed in an HP m7160n, also installed a 750W PSU to supply the extra power.
