I bought a computer installed with an i5-3550 processor on the DH77EB motherboard. It has 8 GB (4 GB x 2) Kingston HyperX RAM. The default memory frequency is 1333 MHz and I have to manually change it to 1600 MHz to fully utilize the RAM chips.
When I try to change the speed, I get the following options:
Along with the options mentioned above, the following parameters also show up.
tCL = 9
tRCD = 9
tRP = 9
tRASmin = 24
The thing is that I don't know whether I should keep the last 4 parameters (9-9-9-24) as is. Also I don't know what the '12' in 12:1600 means. Please help.
The memory controller built-in on the processor will support DDR3-1333/1600 rated at 1.5V. Our recommendation is contacting the memory manufacturer directly to confirm which profiles the memory you have installed will support:

Thanks Dan! I switched to the 12:1600 option without changing anything else and its working fine.
