In regards to the multiplier being at 34x, don't worry. 33x is the default for i5-2500k CPUs (3300Mhz), however you have nothing to worry about it being at 3400Mhz. Your CPU could probably do 4000Mhz (4.0 Ghz) at stock voltage like most i5-2500k CPUs. They're great overclockers.
To change the timings, go into your bios and, if you can, set the ram timing mode to "Manual". If there's no setting like that just ignore that and go straight into the RAM Timings menu if you can and manually input the CL9 timings using the num pad. The 4 numbers you want to take notice of are
9-9-9-27. That's all you'll need to input.
If you have any issues booting or get crashes in the desktop after making these changes, restart and set the timings back to what they were before (CL11) and report back.
EDIT: Forgot to add: make sure you set your RAM voltage to 1.65 manually instead of Auto when setting the RAM timings, as this is what your specific set of RAM requires to be run at for running 1600Mhz CL9 speeds as stated in the timing menu. Do not be afraid of upping the voltage in this scenario to 1.65 as this is perfectly safe and is what the manufacturer intended this RAM to be run at.
