Dear Customer,
Thank you for contacting Bitspower.
According to the water block kit BP-RAMS44PS-DRGB,
Which fits for DDR4, the length and height of the RAM cover are 125.2mm and 32mm.
You can see the dimension picture from the following link.
Sorry, we don't have the distance between top screw holes.
Why do you need that?
