To set up 4750g of memory on a computer system, you would typically need to adjust the memory allocation settings in the BIOS or UEFI firmware, depending on the specific hardware configuration of your machine. Here are the steps you can take to properly set up 4750g of memory on your system:

1. Check Hardware Compatibility: Before proceeding with setting up 4750g of memory, you need to ensure that your motherboard and processor are compatible with this memory capacity. Make sure to consult the specifications of your hardware to confirm that it can support 4750g of memory.
2. Install the Memory Modules: Physically install the memory modules into the memory slots on your motherboard. Make sure to align the notches on the memory module with the tabs on the memory slot and apply even pressure to seat the module properly.
3. Boot the System: Once the memory modules are installed, power on your computer and boot into the BIOS or UEFI firmware by pressing the designated key during the boot process (usually Del, F2, or F12).
4. Navigate to Memory Settings: In the BIOS or UEFI firmware, locate the memory settings menu. The exact location and naming of this menu may vary depending on the motherboard manufacturer and firmware version.
5. Adjust Memory Allocation: Within the memory settings menu, look for an option that allows you to configure the memory allocation. You may need to select the XMP (Extreme Memory Profile) or set the memory frequency and timings manually to ensure proper operation of the memory modules.
6. Set Memory Capacity: Locate the option that allows you to set the memory capacity or memory size. Enter the value of 4750g (4750 gigabytes) to allocate the full capacity of memory for use by the system.
7. Save and Exit: After configuring the memory settings, save the changes and exit the BIOS or UEFI firmware. Your system will reboot, and the new memory capacity should be recognized and available for use by the operating system.
8. Verify Memory Capacity: Once the system has booted into the operating system, you can verify the memory capacity by checking the system properties or using system information tools to confirm that 4750g of memory is recognized and available.
It is essential to note that setting up 4750g of memory may require advanced technical knowledge and understanding of memory configurations. Improper settings or incompatible hardware can lead to system instability or failure to boot. Therefore, it is recommended to consult the motherboard manual or seek assistance from a qualified technician if you are unsure about the memory configuration process.
