4GB DDR3L SODIMM for Dell Latitude

This 4GB DDR3L 1600 module is built for Dell Latitude 7404, E5250, E5450, E5550 and E6440 notebooks. It targets users who need a straightforward capacity increase on those specific platforms. The single 1Rx8 rank fits the factory slot layout without requiring paired modules.

204-pin unbuffered non-ECC fits factory slot

The 204-pin SODIMM plugs directly into the existing memory socket; no adapters or BIOS changes are needed. Because it is non-ECC and unbuffered it matches the original specification, leaving any second slot free for another identical module if the chassis provides one. JEDEC and ROHS compliance keeps the upgrade warranty-safe.

CL11 at 1.35V sustains steady throughput

Rated at CL11 and 1.35V, the module delivers consistent bandwidth during extended multitasking sessions rather than only in brief bursts. Low-voltage DDR3L operation reduces thermal load on the compact Latitude chassis, helping maintain stable frequencies over long workloads.

Spurningar um þessa vöru

How does the 1.35 V operating voltage affect thermal limits during sustained workloads?

The DDR3L module runs at 1.35 V instead of the standard 1.5 V, reducing power draw and heat output so the memory itself rarely becomes the thermal bottleneck in a Dell Latitude chassis.

What noise or heat should I expect when the SODIMM runs continuously in a Latitude E5450?

The unbuffered 204-pin SODIMM has no heat spreader and no moving parts, so it adds negligible heat and zero audible noise; system fan behaviour stays governed by the laptop's own thermal profile.

Which specific Dell Latitude models must I already own for this 4 GB stick to be compatible?

The module is validated for Latitude 7404, E5250, E5450, E5550 and E6440; any other system is outside the tested compatibility list.
