(double data rate) the data rate provides twice the memory bus frequency. So if the memory bus speed is 800mhz and you are using -1600 memory, the ram is running at the correct speed.interface:2 Laptop RAM 200PIN Laptop RAM 204PIN4 Laptop RAM 260PIN2 667MHZ CL = 5-5-52 667MHZ CL = 6-6-6 1600Mhz CL = 11-11-11 1333Mhz CL = 9-9-94 2400Mhz = 17-17-174 2666Mhz = 19-19-19According to different computer models, the CL value will change slightly, which will not affect the operation of the computerPlease e sure that the RAM and slot are cleaned up before installation, so as to avoid dust in the slot, resulting in poor contact between the RAM and the slotProduct Descrtiond works perfectly before shping.Support dual 2 is a product/4 is a productset Brand:SE/HY/Cru..Mic...There are 8 or 16 s, shped ly Colors are green and black, shped lyColor: green, black (sent ly)Noticed:1.
