Figure 7 shows one of the 24 memory chips present on the TITAN X. It is an H5GQ4H24MFR-R2C from SKhynix chip, with 4 Gib (512 MiB) of capacity and maximum clock of 3.5 GHz (7 GHz effective). Therefore, there is no room to overclock the memory within its specifications. You can, however, try to rise the memory clock above its limit.

Figure 8 shows the voltage regulator circuit of the GTX TITAN X. It uses six phases for the GPU and two phases for the memory chips.

In Figure 9, you see the GeForce GTX TITAN X and the GTX 980 without their coolers. Notice that the printed circuit boards have the same size, but differ on the size of the GPU chip, amount of memory chips, and voltage regulator design.
