Dell Inspiron memory upgrade

This 4 GB DDR3L SO-DIMM is built for the Dell Inspiron I15-3521 I15Rv-6143Blk and I15Rvt-6195Blk laptops. It adds a single 1Rx8 module to systems that accept 204-pin unbuffered memory. Buyers needing ECC protection or registered DIMMs should look elsewhere.

Single stick, direct fit

The package contains one memory stick rated at 1600 MHz with CL11 11-11-11 timing and 1.35 V operation. No extra cables, brackets or software are included, so installation is a straight swap into an available SO-DIMM slot.

Low-profile green PCB

Without a heat spreader the module keeps a slim profile for tight chassis clearances. Major-brand chips on a standard 204-pin PCB deliver reliable contact in daily use, while the 1.35 V rating reduces power draw compared to legacy 1.5 V DDR3 parts.

Questions about this item

Will the 1Rx8 DDR3L chips on this CM5126412800SOSRL module need replacement under normal laptop use?

The unbuffered non-ECC DDR3L stick has no moving parts or batteries; it is designed to last the usable life of the Dell Inspiron I15-3521 or I15Rv-6143Blk without scheduled replacement.

What limit appears first when this 4 GB DDR3L 1600 CL11 stick runs sustained workloads in the Inspiron?

The 4 GB capacity ceiling is reached before the 1600 MHz bus or CL11 latency become bottlenecks, so memory-intensive tasks will hit the size limit first.

How much heat and power does this 1.35 V 204-pin SO-DIMM produce during all-day operation?

At 1.35 V the module draws minimal power and runs cool without a heat spreader, adding negligible heat or fan noise inside the Dell Inspiron chassis.
