How to install Transcend DDR3-1866 Registered DIMM

Before you begin, power down your Mac completely, unplug from the power source, and discharge static from your body by touching a grounded metal surface. Open the appropriate access panel following your model’s service guide to reach the memory slots. Identify the correct memory channel layout and locate the empty RDIMM slots. Align the notch on the DIMM with the key in the slot, then carefully insert the module at a slight angle. When the notches are aligned, apply even pressure to seat the DIMM firmly into place until the side latches click, securing the module. If you’re installing multiple modules, install them in the recommended order and symmetry to maximize bandwidth and channel performance. Reassemble the case, reconnect power, and boot the Mac. macOS should recognize the new memory during startup, and you can verify memory size in the About This Mac utility or System Information. If the system does not boot, reseat each DIMM one at a time to identify a potential seating issue or slot compatibility limitation. For best results, avoid mixing different memory brands or speeds in the same system unless the manufacturer explicitly supports dual- or multi-channel configurations with tested kits.

Inexpensive and Nice Quality
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
I was hoping there would be more of a firmness to these pillows, however they are more soft than I was expecting them to be. Id recommend these pillows for someone who wants a fairly non firm pillow.

Soft and Comfortable Pillow
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
This pillow has a soft feel with a nice balance of comfort and support. It fluffs up well after opening and maintains its shape throughout the night. The cover feels smooth, and the overall construction appears well made. A comfortable option for side and back sleepers looking for a plush sleeping experience.

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
These pillows are quite soft and flat, and offer very little support. I sleep on my side and can't use these pillows. I don't know why they're recommended for side sleepers.
