How to set RAM frequency to 1600 MHz for DH77EB motherboard with i5-3550 processor?

Hi,

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:

8:1067

10:1333

12:1600

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.

Thanks!

Hello Akash,

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:
