Replacing the CPU

To upgrade the CPU for better performance of your PC, you need to replace the CPU first.

Caution:

  • Check the location and the type of the CPU on the mainboard, and do the following.

  • The shape of CPU cooler (cooling fan and heat sink) may vary by model, but its order of assembly and disassembly are the same.

  • Please use the service center if you are not experienced with replacing computer parts.

  • You will be charged for replacement and expansion services, even if they are requested within the warranty period.

  • According to the model specification, a duct may not be provided.

  • The heatsink becomes hot if you use the computer, so replace the CPU after it has cooled down.

  • To replace the CPU, do not forget to contact our PC Customer Support Center (1544–7777) for information on purchasing and installing a CPU.

  • The CPU may be damaged if the CPU socket location does not correspond with the description on the CPU.

  • Do not remove white fluid below the CPU or the CPU cooler. It is cooling agent. It may cause an impairment.

  1. Open the computer lid.

  2. Please detach the power cable of the fan.

  3. Unfasten the four screws fixing the CPU cooler and pull the CPU cooler up to remove it.

Replacing / Adding Memory

You may need to expand the PC memory for better performance.

Tip:

  • We recommend using a service center certified by LG Electronics to expand the memory for a service fee. LG Electronics disclaims any responsibility for damage resulting from uncertified service or arbitrary disassembly.

About Memory

Check the specifications and features of the current memory before purchasing a memory.

This computer uses the 288-pin DIMM(Dual In-Line Memory Module) type DDR5 SDRAM.

Specifications

DDR5–4800 (PC5–38400)

However, the operating speed of the memory depends on the CPU specifications.

Type

8 GB (8,192 MB), 16 GB (16,384 MB)

Each slot supports 16 GB (16,384 MB), and the maximum memory capacity of the main board is 32 GB (32,768 MB).
Tip:

Before installing the memory

  • When disassembling the computer, wear gloves to prevent injuries from the internal parts of the computer or the expansion slot.

  • As memory is vulnerable to static electricity, beware of static electricity when removing or installing memory.

  • Check the specifications of the current memory and the new memory before expanding memory.

  • Depending on the system environment and your Windows version, the size of the installed memory and the memory displayed in Windows may be different.

  • When expanding the memory, use a memory of the same specifications ( DDR5 SDRAM for 1.1 V).

  • The DDR5 memory offers improved data transmission rates compared to existing memories and has a different shape.
