Compatible DDR3 1333 Upgrade

This 4 GB DDR3 1333 module replaces the Super Talent W1333UB4G9 in desktop computers. It runs at 1.5 V with CL9 latency and uses an unbuffered non-ECC design. The 240-pin DIMM fits standard desktop slots for a straightforward capacity increase.

Verify DDR3 Slot and Voltage

Confirm the motherboard accepts DDR3 memory and supplies 1.5 V to the DIMM slots. Check that an unbuffered non-ECC module is supported and that a free 240-pin slot is available. The system must be able to operate at 1333 MHz or automatically down-clock the module.

Replaces Super Talent W1333UB4G9

This module is a direct equivalent for the Super Talent W1333UB4G9 part number. The upgrade is worthwhile when the existing system has an open DDR3 slot or when replacing a smaller or slower DDR3 stick to raise total memory capacity.
