Vanity Mining Error? Well after getting a new graphics card (7770) I can mine bitcoins at around 120 - 180 Mhash/s Depending if I run it at full power or not.

Now I thought I would try and mine myself an address using it but the miner just seems to not work.

Using Vanitygen (Linked below) oclvanitygen I set it off mining with reports of it mining at around 4MKeys/s but nothing was showing up after 5 mins worth of time(I tried a simple prefix of 1r).

I then tried using just vanitygen64 and in seconds it found an address.

Does anyone know why?

All you need to do is to add two lines to oclengine.c:

vg_ocl_device_getstr(vocp-&gt;voc_ocldid,
                           CL_DEVICE_NAME);
                           CL_DEVICE_NAME);
+           if (!strcmp(dvn, "Tahiti") || !strcmp(dvn, "Barts") || !strcmp(dvn, "Pitcairn"))
+               quirks &amp;= ~VG_OCL_AMD_BFI_INT;
            if (!strcmp(dvn, "ATI RV710")) {
            if (!strcmp(dvn, "ATI RV710")) {
                quirks &amp;= ~VG_OCL_OPTIMIZATIONS;
                quirks &amp;= ~VG_OCL_OPTIMIZATIONS;
                quirks |= VG_OCL_NO_BINARIES;
                quirks |= VG_OCL_NO_BINARIES;


Add the lines starting with +, but don't copy the plus sign.

This code adds optimizations for AMD HD 68XX, 69XX, 7XXX
