More Information

The HP Server Memory 4GB DDR2 PC2-3200 is a 4 GB DDR2 SDRAM module that operates at a speed of 400 MHz. It has a PC2-3200 rating and is an ECC (error-correcting code) registered RAM module, which means that it is designed to work with systems that have a memory controller built into the CPU or motherboard and that support error-correction. DDR2 SDRAM is an older type of memory that is not as fast as newer DDR3 or DDR4 SDRAM, but it is still commonly used in some systems. The ECC feature of the memory module can help to improve the reliability and integrity of the data being transmitted by detecting and correcting errors as they occur. The module is also a registered RAM module, which means that it is intended for use with systems that have a memory controller built into the CPU or motherboard. It has a 240-pin DIMM (dual in-line memory module) form factor, which is a common type of memory module used in desktop and server systems.

High Performance

Performance 343057-B21 is a type of memory module (also known as a RAM stick or DIMM) that is used in computers. It is specifically a 4GB DDR2 RAM module, which means it is a type of Double Data Rate (DDR) memory that is used in conjunction with a memory controller to transfer data to and from the computer's central processing unit (CPU).

The "PC2-3200" part of the name refers to the module's speed rating, which indicates the maximum rate at which it can transfer data. In this case, "PC2-3200" means the module can transfer data at a maximum rate of 3200 megabytes per second.

The "ECC" part of the name stands for "Error Correcting Code," which means that the module is equipped with additional memory cells that are used to detect and correct errors that may occur during data transfer. This is particularly useful in mission-critical systems where data integrity is important.

The "400MHz" part of the name refers to the module's operating frequency, which is the speed at which it can communicate with the memory controller. In this case, the module has an operating frequency of 400 megahertz.

The "Registered DIMM" part of the name refers to the module's physical form factor and the type of electrical signaling it uses. A Registered DIMM is a type of memory module that uses a register to buffer the data being transferred between the module and the memory controller. This can help improve the stability and performance of the memory system.

Finally, the "240 Pin" part of the name refers to the number of pins (i.e., small metal connectors) on the module's connector. In this case, the module has 240 pins.

Improved Efficiency

It is not clear what you mean by "Improved Efficiency" in relation to the 343057-B21 HP 4GB DDR2 RAM module. The specifications of the module, as listed in the name, do not include any reference to improved efficiency.

However, some of the features of the module, such as its error correcting code (ECC) capability and its registered DIMM form factor, may contribute to improved efficiency in certain contexts. For example, the ECC capability can help ensure the integrity of data being transferred to and from the module, which can help reduce the need for error correction and improve system performance. Similarly, the registered DIMM form factor can help improve the stability and performance of the memory system by buffering the data being transferred between the module and the memory controller.

It is worth noting that the term "efficiency" can have different meanings in different contexts, and it is not clear how it is being used in relation to this particular RAM module.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.


You must be in search of a more competitive compute horsepower which urges you to land here. As predicted by a well-renowned organization, humans will interact with online devices 5000 times a day by 2025- that's not far in the future! Thus, pouring the chunks or information into online connected devices calls for faster language processing, more immediate data access, easy hot swaps, and AI technology, all of which must be fueled by the best memory modules.

Why PC2 3200 SDRAM?

In this regard, the PC2 3200 DDR2 SDRAM is designed in such a way to fill the gap in low data transfer rates, real-time processing, and handling the sheer volume of data closer to the processor-the computing brain! We, at ALLHDD, will help you get the answers to all the mind-boggling questions and imminent bottlenecks regarding the PC 3200 RAM or memory module in 2 variants, mainly 4GB and 8GB.

ECC Certified PC2 3200 - Registered vs. Unbuffered:

ECC registered DDR2 modules pave the way for the data server centers or business organizations to develop a sort of integrity and safety. But there lie two options for the ECC-certified DDR3 SDRAMs. One form is registered while the other goes for the unbuffered one! Each type has its own perks and uses in the industry.

Tech-savvies usually love the ECC Registered PC2 3200 RAM due to being reliable, efficient, and putting less stress on the CPU memory controller. The reason where it lacks behind the unbuffered one is the extra CPU cycle that puts the work into a slower dip. Supporting the tech-enthusiasts and the need to piling up voluminous data on the servers, we have got you covered with the 4GB and 8GB PC2 3200 DDR2 SDRAM in ECC Registered form here at ALLHDD.

  • Especially in the 4GB category, we have genuine HP memory with a 240 pin 400MHz memory for Proliant servers.

Reduce the load on Memory Bus:

AMD's latest ''Infinity Fabric'' technology is much affected by the onboard DDR2 module. It is tied to the memory bus speed, which can support double data rates once equipped with faster DIMM RAM modules to bring the imaginary performance into real-life. Thus, the Load-Reduced Dual Inline Memory Modules (LRDIMM) were introduced to lower down the memory bus' stacking and overloading.

What's noteworthy is how efficiently these PC2 DIMM RAMs are equipped with the buffers chips to deal with the parallel memory bus modules. Thus, make sure to buy the DRAMs with DIMM format and Dual Rank Memory- having a more extensive data access option, reduced load on the memory bus, and easy handling for the sheer volume of data.

Why Buy From ALLHDD?

ALLHDD is the server and network hardware planet dealing with the bare metal pieces fully equipped with performance and efficiency. We empower millions of tech-savvies with the best PC2-3200 SDRAMs with dual rank memory, and ECC registered format to extract the maximum out of that smaller data cache chip.
