lots of issues with that MB if you can, exchange it for another model/brand.
if you can't, then update the BIOS to the latest on the ASUS website.
try a different SATA port and cable.
I see this a lot as the answer for most issues with this MB:
1) Set DRAM Read to Read to 7
2) Set Command Rate to 2T (AKA Command Mode)
3) Set CPU/NB voltage to around 1.30V
4) Set DRAM Voltage (VDIMM) to the specified voltage of the memory used.
Also, what OS are trying to install?
