The Athlon 64 939 support dual channel.
but in the test in s2865 with d0 Athlon64 939 in LinuxBIOS, it only work with one DIMM in socket 1.
weird....

Eric,
the code in raminit.c is_opteron will treat my athlon 64 (939) as Opteron too.

static int is_opteron(const struct mem_controller *ctrl) { /* Test to see if I am an Opteron. * FIXME Testing dual channel capability is correct for now * but a beter test is probably required. */ #warning "FIXME implement a better test for opterons" uint32_t nbcap; nbcap = pci_read_config32(ctrl->f3, NORTHBRIDGE_CAP); return !!(nbcap & NBCAP_128Bit); }
