OWC 8GB DDR5 5600 CL46 1Rx8 288-pin 1.1V UDIMM for Lenovo Legion T5 26ARA8

Lenovo Legion T5 26ARA8 memory upgrade

This 8 GB DDR5 module is built specifically for the Lenovo Legion T5 26ARA8 desktop. It replaces the original Lenovo part 4X71N41631 and fits the system's 288-pin UDIMM slots without modification. The single-rank 1Rx8 design keeps the memory controller load light for stable operation. Buyers needing ECC error correction or registered DIMMs should choose a different module.

Sustained workload behaviour

JEDEC-standard timings of CL46 at 5600 MT/s and a low 1.1 V operating voltage give predictable throughput during long rendering or compile sessions. Without a heat spreader the module relies on case airflow, so temperatures stay acceptable when the chassis fans are running. The unbuffered layout avoids extra latency that registered sticks would add. Systems that demand higher frequencies or lower latencies will not reach those targets with this part.

Deciding specification

The 5600 MT/s DDR5 speed rating is the single figure that determines compatibility with the Legion T5 26ARA8 memory controller. Installing a faster or slower DDR5 module can prevent the system from posting or force it to run at a reduced rate. Matching this exact data rate ensures the firmware trains the link at its intended frequency. Any other DDR generation will not fit the 288-pin slot at all.
