What does H in PC3-10700H memory stand for?

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.

Solution 1:

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.
