Is my Ram operating at the right Mhz and Timings

Pardon my question, as I'm sure its obvious for those who know. I just upgraded from 6GB of memory to 16GB of memory of the following type:

G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9Q-16GBRL

It works fine (computer boots), when I run Speccy however I get the following as the recognized memory:
16 GB Dual-Channel DDR3 @ 795Mhz (11-11-11-28).

At first I thought this was running at half the speed it should be. Then I read some postings about doubling the actual speed to get the effective Mhz as rated. I was further confused when I read on newegg that the stated RAMs timings are 9-9-9-24-2N, as you can see from the Speccy posting it appears to be running at 11-11-11-28.

Is my Ram running at 1600Mhz? Is my timing less than optimal? I don't want to leave allot of speed on the table, if it is a simple matter of adjusting settings in the bios (all my current timing settings are set to auto, I checked before installing the RAM). I'm not interested in overclocking the memory, I just want to get the rated amount, and my motherboard claims to support 1600Mhz+.

Any feedback would be appreciated. Rest of the overview specs are as follows:

It is correct,. DDR stands for Double Date Rate, so the figure is doubled. In your case, 795 doubled = 1595 = close enough.

Most of not all chipsets and/or programs actually report the correct speed anyway which tends to fluctuate anyway. Even a lot of boards with their own sensors don't report this correctly.

Wih regards to RAM timings, you are literally talking about nanoseconds here, but in Auto mode tends to be the safest option. If the figures are too low, you'll have all kinds of other issues.

I wouldn't worry about it.
