Hello
I've bought new Pc few days ago and a friend of mine told me to check everything using cpu-z and hw monitor. I checked all of it and one thing seems little wierd in memory tab the DRam Frequency changes constantly between 720 - 830 mhz is this normal with the new Pc's ?
Here the Pic:

It's normal, nothing to worry about.. All you need to worry about is the pic all the way to the left.. where it says 800, multiply by two and that's the current RAM frequency - for you it's currently 1600, which is correct assuming you're using 1600 MHz memory.

I wish I could explain what the other screens are showing under JDEC but I'm not very educated on that - I do believe the numbers under JDEC are the different timings that the memory can use if running it at the listed frequencies under "JDEC" - Running the memory at a lower frequency often allows for "tighter" timings which can increase performance more than increasing the frequency of the RAM would alone... Usually a combination of tightening the timings and overclocking the RAM frequency is the way to go about getting the most out of your memory.

Anyway, for now, disregard all but the "DRAM Frequency" and remember to always multiply it by two for the "double data rate" (DDR) RAM.

I would use the XMP profile for the RAM as it drops timings from 11-11-11 to 9-9-9 at the same speed. Which type of G.Skill RAM is it? You may be able to hit 1866 or so, depending upon the model. Also, if you are using an Intel CPU then the speed is generally more important than timings, and the opposite for AMD, though you should try for the highest speed and lowest timings you can get either way.
