1600MHz RAM showing 1333 MHz in BIOS

Solution
The Kingston memory is compatible with your system however I'm not sure about the HYNIX module the specification isn't clear. PC1600S? S normally is referred to SO-DIMM modules. CL2.5 for DDR3 1600 memory I do not think so. Please check the label correctly or try running CPU-Z (Click on download now). (If you are running the CPU-Z then check the SPD tab, select the slots and you will find the details of the memory, check the speed and the manufacturer part number).
Also try the process mentioned by in the above post by...

Hi,
Do you have any other speed memory installed in your system other than 1600MHz? Could you let me know the exact mfg's part number of both the Hynix and Kingston RAM?
Note: The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value.
Sometimes the SPDs maybe programmed to JEDEC standard DDR3-1333. You can change the speed manually to 1600MHz in your BIOS. Refer your manual.
Good luck!!

If running at 1333 Ok, then go into BIOS raise DRAM freq to 1600 and add + 0.06 to the DRAM voltage and try that, would guess base timings are at 9-9-9-27 currently, leave them at that or if different try with what the timings currently are and the freq and voltage adjustment I mentioned, if it fails with current timings, try the 9-9-9-27 I showed above

Thank you.

Also try the process mentioned by in the above post by Tradesman1. In the BIOS click on the Performance Tab to adjust the memory frequency. Read your manual <- Click here.
Good luck.
