Asus ROG Zephyrus G GA502 Disassembly and RAM, SSD upgrade options

In this article, I will explain how to remove the Asus ROG Zephyrus G GA502 bottom case and show you how to upgrade the M.2 SSD and memory.

Turn off your computer and remove all devices connected to your computer.

First, you need to use a screwdriver to remove all the screws that secure the bottom cover, then use the old card or thin plastic tool to slowly open the bottom cover.

After removing the bottom cover, please disconnect the battery cable from the motherboard to avoid damage to the notebook hardware due to the short circuit.

As can be seen from the picture, the GA502 has adopted the red motherboard of the ASUS ROG series. Its upper part includes the system board, the heat dissipation module, and the lower part includes the battery and the speaker.

This notebook uses 8GB of onboard memory, plus a memory slot, and comes with an 8GB DDR4 2666HZ memory, a total of 16GB of memory, if necessary, you can add a 16GB of memory to replace this 8GB of memory

There are two SSD slots in total, one is 4x, and the other is 2x, but… Yes, the latest SSDs in the Rog laptop has been replaced by the Intel QLC 660p, and even worse, the GA502 comes standard with 512G SSD, after writing the cache. The write speed is in double digits… This is a bit awkward, or Asus should give a big capacity SSD. Otherwise, the user will not fully understand the advantages of QLC.

The cooling module has four copper tubes, two thick and two thin. It can handle 35W 3750h and 1660ti MQ without any pressure. However, the 1660ti MQ of ga502 is a special overclocking version with a performance between MQ and normal version.

The cooling module has two large fans. Asus says it uses a glacier cooling structure. The actual cooling effect is really good. The GA502 can be plugged into the game’s configuration in a 2cm body. This cooling system is indispensable.

It uses a 76wh lithium battery, we tested it using PCMark, and the test results show that it can last for three and a half hours.
