Opsætning og installation

Installing RAM in an iMac requires careful handling. Always refer to your specific iMac model's official service manual for detailed instructions. The following steps provide a general overview.

Sikkerhedsforanstaltninger:

• Always power off your iMac and unplug all cables (power, USB, Thunderbolt, Ethernet, etc.) before beginning.
• Allow the iMac to cool down for at least 10 minutes before handling.
• Work on a clean, flat, and static-free surface.
• Discharge any static electricity from your body by touching a grounded metal object before handling the memory modules.
• Avoid touching the gold connectors on the memory modules.

Installation Steps (General for 27-inch iMacs):

1. Prepare the iMac: Lay your iMac face down on a soft, clean cloth to protect the screen.
2. Locate the RAM Compartment: On 27-inch iMac models, the RAM compartment is typically located on the back, near the power port. It's usually covered by a small access panel.
3. Open the Access Panel: Use a small, non-conductive tool (like a spudger or a pen) to press the small button or latch next to the power port. The memory compartment cover should pop open.
4. Remove Existing RAM (if applicable): If you are replacing existing RAM, gently push the ejector clips on either side of the memory module outwards. The module will pop up slightly. You can then pull it straight out.
5. Install New RAM: Align the notch on the Timetec memory module with the key in the memory slot. Insert the module firmly into the slot at an angle until it clicks into place. Then, push down on the module until the ejector clips snap into place, securing the module horizontally.
6. Repeat for all Modules: Install all four Timetec 4GB modules into the available slots.
7. Close the Access Panel: Replace the memory compartment cover, ensuring it clicks securely into place.
8. Tilslut igen og tænd: Carefully return the iMac to its upright position, reconnect all cables, and power it on.
9. Bekræft installationen: Once the iMac boots, go to Apple menu > About This Mac to confirm that the new memory is recognized.
