Frequently Asked Questions - M471A5244CB0-CWE SAMSUNG

Is the Samsung M471A5244CB0-CWE compatible with my laptop?

It is a standard DDR4-2400 SO-DIMM module. Check your laptop's specifications to ensure it supports 4GB capacity and DDR4 SO-DIMM form factor.

How do I install this memory module?

Turn off the laptop, remove battery if possible, locate the memory slot, align the notch, insert at a 30-degree angle, then press down until clips lock.

What should I do if my laptop does not recognize the memory?

Ensure the module is fully seated and locked. Try reseating it. If still not recognized, test in another slot or verify compatibility with your motherboard.

Can I mix this module with other memory modules?

Mixing different speeds or capacities may work but could cause instability. For best performance, use identical modules or ensure they are matched.

What speed does this module run at?

It runs at 2400 MHz (PC4-19200). If installed with slower modules, it may downclock to the slowest common speed.

Is this module compatible with Intel and AMD systems?

Yes, it works with both Intel and AMD platforms that support DDR4 SO-DIMM and 1.2V operation.

What is the warranty period for Samsung memory?

Samsung typically offers a limited lifetime warranty for memory modules; verify with your retailer.

How do I clean the contacts on the memory module?

Use a soft, lint-free cloth lightly moistened with isopropyl alcohol. Gently wipe the gold contacts and allow to dry completely before reinstalling.

Can I use this module in a desktop PC?

No, this is a SO-DIMM designed for laptops. Desktops use DIMM modules; check your desktop's form factor.

What does the model number M471A5244CB0-CWE indicate?

M471 indicates Samsung DDR4 SO-DIMM, A is DDR4, 5244 denotes 4GB capacity (sometimes 5=8GB but this is 4GB from spec), CB0-CWE is a revision code.

Module Handling Guide

How to handle the module

Recently, module failures related to Active/Passive/Component cracks have increased.

The main root causes are wrong handling methods and mechanical damage.

Current products have more capacitors and resistors, and the sizes of those passives are reduced, with most of them located around the edge area.

These characteristics require a more cautious module handling method.

This guide book attempts to identify the tendency and range of module crack patterns based on experiments from several aspects. The main purpose is to reinforce Samsung's process control and help customers effectively control the module handling process.

Test methods include PCB Bow, Twist, Drop Test, and UTM (Universal Testing Machine) Test for DRAM, Resistor, and Capacitor. We observed crack phenomena and tendencies through the data and pictures. Tested products are limited to Registered DIMM [RDIMM], Unbuffered DIMM [UDIMM], and BOC PKG based modules; therefore, test results might differ when applied to other products.

Memory Module Introduction

Unbuffered DIMM

Load Reduced DIMM

Registered DIMM

SODIMM

• Anti-ESD * straps should be used. • The strap should be linked to your body.

*ESD : Electro Static Discharge

• Modules should be picked up from packing trays only one-by-one. • Product should be handled at the conductive mat.
• Do not grab packages. Hold only the edge of the PCB with both hands.
• Wear gloves when handling.

- Tray must be covered when handling module tray.

- Do not twist or bow a module.

- Do not drop modules on the floor.

- Do not grip several modules using one hand.

- Do not touch module without gloves. It can cause tab contamination.

- Do not detach H/S * or clip. (FDHS product) *H/S : Heat Spreader

- Handling modules near tools is prohibited because hard metal objects can damage Module.

- Do not insert the module by seating one end first then seating the other. (This is called zippering or rock)

- Do not insert module upper side.

- Do not insert module between sockets.

- Do not insert key notch reverse.

- Do not insert several modules at the same time.

- Do not use metal tools when socketing.

1. Socketing must be conducted before turn-on.
2. Ensure that both latch ejectors of connector are fully opened.
3. Grip the module edge side with both hands. (avoid touching component area)
4. Align module to socket notch & side guide.

1. Press down both edge side of module at the same time.
2. Confirm latch ejectors closed properly.

We validated the possibility of cracking tendencies through various tests. Various products, environments, and characteristics of tools can cause errors and affect test results.

However, the most important conclusion that can be deduced from the tests is that special caution against mechanical damage and handling errors should be taken from the point of unpacking modules to inserting them into the sockets on system boards.

Recent memory module products are structurally weak to external damage due to the increasing numbers of ICs and passive components and the unit's diminishing size.

It's difficult to predict and find out clear root causes of failures related with BOC PKG passive components due to many variances and circumstances. However, the above guidelines for memory module handling based on test results should help with crack-related problems and make more effective process control possible.
