Overview of HPE 708639-B21 8GB DDR3 SDRAM
The HPE 708639-B21 is an 8GB DDR3 SDRAM that is designed for use in HPE Proliant BL460C Generation 8 servers. It is a genuine memory module manufactured by Hewlett Packard Enterprise (HPE) and has been specifically designed to meet the high-performance requirements of modern servers. The memory module has a 240-pin DIMM form factor, which is a common form factor for DDR3 SDRAM, and is rated for a clock speed of 1866MHz.
In this article, we will take an in-depth look at the features and specifications of the HPE 708639-B21 8GB DDR3 SDRAM, including its clock speed, capacity, and rank. We will also explore the benefits of using genuine memory in servers and the advantages of using ECC registered memory.
Clock Speed & Capacity
The clock speed of a memory module determines how quickly data can be transferred between the memory and the CPU. The HPE 708639-B21 has a clock speed of 1866MHz, which is the maximum speed supported by the Proliant BL460C Generation 8 servers. This clock speed provides a significant increase in data transfer rates over older DDR3 modules, which typically had clock speeds of 1333MHz or 1600MHz.
The HPE 708639-B21 has a capacity of 8GB, which is a common size for DDR3 memory modules. This capacity is sufficient for most server applications, but higher capacity modules are also available for applications that require more memory. The Proliant BL460C Generation 8 server supports a maximum of 384GB of memory, which can be achieved using 48 8GB modules.
Rank of DDR3 SDRAM RAM
The rank of a memory module refers to the number of independent sets of memory chips on the module. The HPE 708639-B21 is a dual rank module, which means that it has two independent sets of memory chips on the module. Dual rank modules are more efficient than single rank modules, as they can provide twice the bandwidth between the memory and the CPU. This makes the HPE 708639-B21 ideal for high-performance server applications that require large amounts of memory bandwidth.
ECC Registered Memory
The HPE 708639-B21 is an ECC registered memory module. ECC stands for Error Correction Code, which is a technology that detects and corrects errors that can occur during data transmission. Registered memory, on the other hand, is a type of memory that uses a register to buffer the control signals between the memory and the CPU. This helps to reduce electrical loading on the memory controller and allows for larger memory capacities.
ECC registered memory is essential for servers that require high levels of reliability and data integrity. It is particularly important in applications such as database management, financial transactions, and scientific computing, where even small errors can have significant consequences. By using ECC registered memory, the HPE Proliant BL460C Generation 8 server can detect and correct errors that can occur during data transmission, ensuring that data is always accurate and reliable.
Advantages of Genuine Memory
Using genuine memory in servers provides a number of advantages over using third-party or counterfeit memory modules. Genuine memory modules are manufactured to strict quality standards and are tested rigorously to ensure that they meet the specifications of the server manufacturer. This ensures that the memory module will operate reliably and efficiently in the server, minimizing the risk of downtime and data loss.
Third-party or counterfeit memory modules may be cheaper than genuine modules, but they often have lower quality standards and may not be compatible with the server. This can lead to compatibility issues, reduced performance, and increased risk of system failures.

About New Bulk Pack Products
Memory - PC3-14900
If you've just landed at ALLHDD, you must already know what RAM is! In case you don't, it's physical hardware in the CPU to temporarily store the information. Things are not as simple as they look! With the networking servers bloating up with the information and data, the data transfer and loading speeds are suffering from a dip. In turn, the data processing has become slower, affecting the jobs of many! Worry not, as we have got you covered with the best solution on-board.
DDR3 RAMs follow the synchronous mode and are the 3rd iteration in the SDRAM category. When launched, this SDRAM has got the title of ''go to RAM'' across the networking platforms worldwide.
DDR3 RAM Has Narrowed Down The Gap!
DDR2 and DDR3 chips typically follow the same size but somewhat different pin nodules. The developers have to narrow down the space between the pins as the DDR2 features the 200-pins in SODIMM form while the DDR3 contains 240-pins in the DIMM form. Later on, the developers have launched the 240-pin nodule in the unbuffered form of DDR2 as well.
Higher Bandwidth Up To 1600 MHz:
PC3-14900 memory module follows the higher data transfer speeds while reading, writing, or transferring the chunks of data. DDR3 SDRAM offers up to 1600 MHz of speed which supports higher bandwidth with its unique functionalities on-board. DDR3's much higher speed and performance depend on the 8-bit deep prefetch buffer, which is far better than the 4-bit prefetch buffer compared to the predecessor.
PC3-14900 Offers Better Clock Speed:
DDR3 SDRAMs are famous for their higher bandwidth along with better and sufficient clock speeds. That's what makes it an ideal and best-suited choice for the server rooms and business centers. The DDR2 used to feature the 400-800 MHz of clock speed while the DDR3 PC3 14900 can support up to 1600 MHz - double than the previous generation!
The DDR3 SDRAMs are proven much effective in the falling and rising edge 400-800 MHz I/O clock. To help you get the right deal we, at ALLHDD, have combined a list of PC3 14900 options: 8GB, 16GB, 32GB, 48GB, 64GB, 128GB, 256GB, and 512GB as well, check them out and find the best for you.
PC3-14900 Utilizes Low Power:
What's noteworthy in DDR3 memory modules is their less power consumption than the DDR2 and DDR. The manufacturers and tech-savvies claimed a reduction of 30% power in the former one due to being supported with the supply voltage of 1.5V. The DDR2 used to operate on the 1.8V power supply.
DDR3 Rams Are Better With Algorithm Switch!
PC3 14900 DDR3 memory supports the algorithm switch on-board! It features two different algorithms or patterns named Automatic refresh and Self-Refresh. The memory module can switch intelligently, depending on the stress, data, and speed you want.
