specs are:
2500k at 4,4 ghz ,all voltages stock , z77 asuss mb, win 7,
ram :4 x 4 gb g.skill ripjaws x f3- 12800cl9D-8gbxl
All from CPU-z : dram 686.8 mhz
fsb : dram 1:5
cas latency 9.0 clocks
ras 9
ras 9
cycle time 24 clocks
I have no clue what those numbers are , but my question is about "686.8 mhz" should this not be a 1600 something?
Thank you in advance.

Your RAM is running at a little above DDR3-1333. CPU-Z reports the real frequency instead of the effective DDR frequency, so it's reported frequency is half of the frequency that the memory is marketed at.

It's fine.

686 is before the multiplier. You probably are running 1333 a little faster than stock speed.

Is this the result of an auto overclock?

"Is this the result of an auto overclock?"

I think so , I did use Asuss auto tuning , and then manually scaled back a few things,
number of try's , and the system is stable at 103 x 43 for cpu.
So looks like I am all good then , thanks guys.

That 103 is why your RAM ends up a little higher than 1333. Normal base clock is 100.

Your voltages may be using stock VID, but they are much higher than "stock" voltage for your stock frequency. (The voltage goes up automaticall as the clock speed increases)

You should verify your load temps. If you are on stock cooling, you will overheat for sure under full load. Heck, my hyper 212+ couldn't handle an Asus auto tune overclock.

Auto tune went for 4.5 Ghz. It was stable but hot. I manually overclocked to 4.2 and undervolted.

i am a complete n... in oc , but i have run unigine , 3dmark11, some build in to games benchmarks ( total war shogun2 , metro2033 etc..)i had all cpu-z,gpu-z ,speccy, and asuss sensor monitor/recorder on during all this tests,and my voltage stays the same at all times( at least the ones i could see in all this "tools").
But this is one I like most : Intel processor diagnostic tool - it runs 4 minute test , and it tells me approx 51C below max for a cpu.

I should have mention that I am using H100 corsair.

An H100 can handle more heat than a 212+ so you are probably fine.
