Question: I have two Corsair RAMs 4GB DDR3 Desktop memory. CPU-Z reports one as PC3-10700 & other as PC3-10700H. See the attached screenshot.

What does H in PC3-10700H stand for and is there any difference between the two? The part number for both sticks is same. I have searched the internet but could not get any relevant references. 

Thanks in advance.

Answer: 
I believe the H stands for the timing of the RAM module, specifically the timing 9-9-9-9.

I do not believe there is likely any significant difference between the two modules, especially as the part number is the same.

That H generally means that there is an XMP/DOCP profile available for the RAM. It will default to 667MHz, but can likely be bumped up to 800MHz.
