MT41K256M16HA-125:E Introduction

The MT41K256M16HA-125:E is a type of DDR3 SDRAM that works at 1.35 volts and has a low voltage. It has a number of benefits over traditional DDR3 SDRAM, such as using less power and running faster. In this guide, we’ll look at the MT41K256M16HA-125:E DDR3L SDRAM’s most important features, specs, and how to use it.

Overview of DDR3L SDRAM

DDR3L SDRAM is a type of DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic Random-Access Memory) memory card. It is made to work at a lower voltage than standard DDR3 SDRAM, which means it uses less power and uses it more efficiently.

DDR3L SDRAM modules are often used in laptops, PCs, servers, and embedded systems, among other types of computers. They can transfer data quickly and have a lot of memory, which makes them good for demanding apps that need to get to memory quickly and easily.

DDR3L vs. DDR3: Key Differences

The working voltage is the main difference between DDR3L and DDR3. The normal voltage for DDR3 modules is 1.5 volts, while the voltage for DDR3L modules is 1.35 volts.By lowering the voltage, DDR3L uses less power and makes less heat, so it is more energy-efficient.

DDR3L modules are made to work with DDR3 slots, so when they are used with a DDR3 controller, they can run in 1.5V-suitable mode. This compatibility makes it easy to switch systems from DDR3 to DDR3L without having to change a lot of the hardware.

Benefits of DDR3L SDRAM

The use of DDR3L SDRAM has a number of benefits:

  • Lower power consumption: DDR3L works at a lower level of 1.35 volts, which means it uses less power than DDR3. This is especially helpful for mobile devices, where saving power is key to making the battery last longer.
  • Improved Energy Efficiency: The fact that DDR3L uses less power means that computer systems can use less energy. It helps lower the general power needs of the system and the amount of heat it gives off. This means lower energy costs and better thermal management.
  • Compatibility with DDR3 Slots: DDR3L modules are made to fit in DDR3 slots, which makes it easy to update. This means that systems that were originally made for DDR3 can be updated to DDR3L without having to change a lot of hardware or get a new motherboard.
  • High Performance: DDR3L SDRAM has fast data transfer rates that make memory entry quick and easy. This is good for apps that need to process a lot of data, like gaming, editing multimedia, and virtualization.
  • Cost-Effective Solution: DDR3L units are usually cheaper than newer memory technologies like DDR4 and DDR5. This makes DDR3L a good choice for people who want to save money and for situations where the newest memory technology might not be needed.

Overall, DDR3L SDRAM strikes a good balance between how well it uses power, how well it performs, and how much it costs. This makes it a popular memory option for a wide range of computer systems.

Operating Modes

● Low Voltage (1.35V) Mode

The 1.35V low-voltage mode is used by the MT41K256M16HA-125:E DDR3L SDRAM module. When compared to standard DDR3 SDRAM modules that run at 1.5V, this method uses less power and uses it more efficiently.

To make sure that everything works right in low-voltage mode, the memory controller and system must handle DDR3L SDRAM and be able to provide the voltage level that is needed. The power source and voltage regulator in the system should be set up so that the DDR3L SDRAM module always gets a stable 1.35V.

● Compatibility with 1.5V DDR3 SDRAM

The MT41K256M16HA-125:E DDR3L SDRAM module was made to work with 1.5V DDR3 SDRAM as well. This means that when it is used with a DDR3 processor, it can work in 1.5-volt compatible mode.

When the module is in 1.5V compatible mode, it acts like regular DDR3 SDRAM and needs a 1.5V supply power. This makes it easy to switch from DDR3 to DDR3L without having to change a lot of gear.

It’s important to remember that if you use the MT41K256M16HA-125:E module in 1.5V compatible mode, you might not get the benefits of low voltage operation, like less power use. So, to take advantage of the benefits of DDR3L SDRAM, it is best to run the module at its low voltage setting of 1.35 volts.

Configuring voltage and timing

For best performance and compatibility, the MT41K256M16HA-125:E DDR3L SDRAM module should be set up with the right voltage and timing settings. This means setting the supply voltage and setting up the different timing factors.

The voltage and timing values may be different depending on what the system needs and what DDR3L controller is being used. For the suggested voltage and timing specifications, it is important to look at the manufacturer’s datasheet or technical documentation.

Most of the time, you can change the voltage and timing settings in the machine’s BIOS or UEFI settings. For the DDR3L SDRAM module to work well and reliably, these settings should be carefully set up according to the manufacturer’s instructions.

Thermal Specifications

The MT41K256M16HA-125:E DDR3L SDRAM module’s best performance and stability depend on how well it handles heat. For proper heat dissipation and to avoid overheating, it is important to understand the thermal specifications given by the maker.

The thermal specifications for the module may include

  • Ambient temperature range: the range of suggested temperatures at which the module should work. To avoid problems with heat dissipation, it is important to make sure that the surrounding temperature stays in this range.
  • Junction temperature (Tj): The highest temperature that the internal junction of a DDR3L SDRAM chip can reach under normal working conditions. If you go over this temperature limit, the module might not work as well, or it might even break.
  • Thermal resistance (ja and jc): These numbers show the module’s thermal resistance, which shows how well it can get rid of heat. Ja is the thermal resistance between the junction of the module and the air around it, and jc is the thermal resistance between the junction and the module’s case.

To avoid thermal throttling, a drop in performance, or an early failure of the DDR3L SDRAM module, it is important to understand and follow these thermal standards.

Heat Spreader and Ways to Keep Cool

More cooling options can be used to improve the way the DDR3L SDRAM module deals with heat. These methods help get rid of heat more efficiently, keeping temperatures low and making the module more reliable overall. Some common ways to cool down are:

  • Heat spreader: A heat spreader is a piece of metal that touches the memory chips on the module. It helps spread heat widely across the module’s surface, which makes it better at getting rid of heat. Most heat spreaders are made of materials that are good at transferring heat, like aluminium or copper.
  • Heat sinks are passive cooling devices that are connected to the hot parts of the module. They provide more surface area for heat to escape and can be made of aluminium or copper, with fins or other designs to help heat escape more quickly. Most of the time, heat sinks are used with heat spreaders.
  • Airflow and ventilation: Making sure the system has enough airflow and ventilation can help get rid of a lot of heat. Using fans or air systems to cool the system enough can help keep the DDR3L SDRAM module and other parts at a lower temperature.
  • When using heat spreaders, heat sinks, or other cooling solutions, it’s important to make sure they work with the DDR3L SDRAM module and don’t get in the way of how it’s installed or how it works.

It is best to follow the guidelines and recommendations given by the module manufacturer when choosing and installing cooling solutions. This is because the module manufacturer can give specific directions and advice on the best ways to handle heat in relation to the MT41K256M16HA-125:E DDR3L SDRAM module.


In conclusion, the MT41K256M16HA-125:E DDR3L SDRAM is a high-performance memory module that works well with low voltage.
