4GB DDR3 SODIMM for Inspiron 3521

This OWC module is a 4GB DDR3 1600 PC3-12800 CL11 2Rx8 204-pin 1.5V Non-ECC SODIMM built for the Dell Inspiron 15 3521. It arrives new and complies with JEDEC standards for a warranty-safe upgrade. The unbuffered design fits the laptop's memory slot directly. Installation is a straightforward DIY task for most owners.

Suitable for owners adding a single 4GB stick

This upgrade suits users who need to replace a failed module or add one 4GB stick to a free slot in the Dell Inspiron 15 3521. Buyers who want more storage capacity should look elsewhere as this is system memory. Systems requiring ECC or registered modules cannot use this unbuffered Non-ECC SODIMM. Laptops with a different pin count or voltage requirement are not compatible.

204-pin DDR3 1600 CL11 1.5V specification

The decisive specification is the 204-pin DDR3 1600 CL11 1.5V Non-ECC SODIMM form factor. The module must match this exact interface, speed, latency and voltage to function in the target laptop. A different pin layout, DDR generation or voltage will prevent installation or boot. Verify the slot type before purchasing.

Soalan tentang produk ini

Will this 204-pin DDR3 SODIMM fit the memory slots on my Dell Inspiron 15 3521?

Yes, the module is built to the 204-pin DDR3 SODIMM form factor specified for the Inspiron 15 3521.

Can I keep my existing DDR3 1600 CL11 memory and add this 4GB module alongside it?

It will work if the installed memory is also DDR3 1600 CL11 1.5V unbuffered non-ECC; matching speed, latency and voltage avoids down-clocking.

How do I confirm the new RAM is running at PC3-12800 1600MHz CL11 after installation?

Open Task Manager or a system-information tool and verify the reported speed shows 1600 MHz with CAS latency 11.
