Last year, we wrote about the need for gaming hardware to grow up and move beyond RGB. Our pleas have clearly fallen on deaf ears, as the Computex 2018 news blitz is full of even more RGB than before. You know what's worse than RGB memory? Only filling two of your DIMM slots with RGB memory and leaving the others empty!

Gigabyte is boldly forging new ground here, with 'demo' memory modules that allow your PC to fully display its RGB capabilities. Available as a memory kit in June with an estimated price of $229, the Aorus RGB memory kit includes two 8GB DDR4 DIMMs plus two matching 'dummy' DIMMs that can fill the unoccupied slots.
