There's a reason memory manufacturers sell memory as kits..

Its pot luck getting two 4gb kits to run as 8gb (at max ratings). Assuming its only the memory that's at issue (you're booting at default bios settings?) ramp down the speed/timings and find the best they'll do together.

Otherwise consider selling the kits separately and buying a manufacturer's 'matched 8gb kit'. You'd be better off with x2 4gb dimms anyway.
