Premium Brand Chips
Not all memory is the same. Our memory is manufactured using premium brand chips from manufacturers including Samsung, Elpida (NEC), Hynix (Hyundai), Micron and Hypertec. This ensures the highest level of reliability and compatability. You may be able to buy cheaper memory but you will not be able to buy the same quality of memory cheaper.
