OWC 4GB DDR3 1333 SODIMM for Dell Inspiron M531R

This single 4GB DDR3 module runs at 1333MHz with CL9 latency and 1.5V operation. It is built as a 204-pin non-ECC SODIMM using 2Rx8 organisation. The part is validated for the Dell Inspiron M531R 5535 laptop.

Fits one SODIMM slot in compatible Dell Inspiron

The module draws standard 1.5V power and requires no heat spreader. Installation uses the existing memory bay and frees the second slot for another identical stick if the chassis supports dual-channel operation. JEDEC and ROHS compliance keeps the upgrade warranty-safe.

Replaces slower or smaller DDR3 SODIMMs

The jump is worthwhile when the system currently runs less than 4GB or operates at a lower DDR3 speed grade. Buyers needing more than 4GB total capacity or a different DDR generation should look elsewhere.

Questions about this item

Will the CL9 timing at 1333 MHz become a bottleneck during long rendering sessions?

The module runs at DDR3 1333 with CL9 latency, which is the standard timing for this speed grade and does not introduce additional bottlenecks beyond the platform's memory controller limits.

How much heat does the 1.5 V DDR3 SODIMM produce when the laptop runs all day?

Operating at 1.5 V without a heat spreader, the module generates typical DDR3 SODIMM heat; the laptop's existing cooling handles it under continuous load.

Does my Dell Inspiron M531R 5535 need a specific BIOS version or matched DIMM for this 4 GB module to work?

The module is validated for the Dell Inspiron M531R 5535 and follows JEDEC DDR3 1333 specifications; no special BIOS version or matched DIMM is required for single-module operation.
