OWC 16GB DDR5 4800 CL40 1Rx8 UDIMM Aurora R13 R15 memory upgrade

OWC 16GB DDR5 4800 upgrade for Aurora R13 R15

This 16GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It is built as a single 1Rx8 unbuffered UDIMM for Alienware Aurora R13 and R15 desktops. The part meets JEDEC PC5-38400 specifications and carries a limited lifetime warranty with free technical support.

DDR5 4800 speed and platform limits

DDR5 4800 is the base JEDEC data rate for this generation; the memory controller in Aurora R13 and R15 systems will not run this module faster than 4800 MT/s without manual tuning. Four 288-pin slots are typically available, so total capacity depends on how many slots you populate. The 1.1V standard voltage is fixed by the DDR5 specification and cannot be raised on these platforms.

Check slots and existing modules before ordering

Verify how many of the four UDIMM sockets are already occupied in your Aurora R13 or R15. Mixing this 1Rx8 stick with different rank counts or speeds will force all channels to the lowest common settings. Confirm the BIOS is updated to the latest Alienware release for full DDR5 4800 compatibility. Ensure you are not exceeding the maximum supported capacity per slot for your specific motherboard revision.
