Hello All :
Had to upgrade my RAM so I purchases *2 16GB sticks of Crucial DDR4-2400 RAM.

Fits perfect. Shows up correctly as 32GB. Working fine with Cubase 9 PRO.....but....

In Speccy it shows up as exactly half the speed @ 1200 Mhz AND is 400 Mhz slower than the original DDR4-2133 (1600 MHz)

Looked for a setting in the ROG G752VW BIOS, but, nothing is tweakable there.

Is there a way to bump the speed in Windows or an external utility ?

Your speed is exactly what it should be.

For a name like DDR4-2400, you can expect half of the I/O bus clock than the number in the name.

As for the original DDR4-2133 running at 1600MHz, are you sure? Speccy has my DDR4-2133 clocked in at 1066MHz, half of the name number.

Gee, my eyes are not what they used to be for sure, but, maybe that is correct !
Anyhow, the ram is working great and thank you all for the help ...much appreciated.
