Introduction to the HPE DDR3 SDRAM Memory
The HPE 708639-B21 8GB is a high-quality memory module designed for use in servers, particularly the Proliant BL460C Generation 8. This module has a capacity of 8GB and operates at a speed of 1866MHz. It is also designed with ECC registered dual rank DDR3 SDRAM and has a 240-pin DIMM configuration. In this article, we will explain what each of these terms means and how they contribute to the performance and reliability of the HPE 708639-B21 memory module.
Capacity and Speed of 708639-B21 RAM
The HPE 708639-B21 memory module has a capacity of 8GB, which means it can store up to 8 gigabytes of data. This is a relatively large amount of memory, which makes it suitable for use in servers that require a lot of processing power and need to store and access large amounts of data quickly.
In addition to its large capacity, the HPE 708639-B21 module operates at a speed of 1866MHz. This is the maximum speed at which the module can transfer data to and from the server's CPU. The higher the speed of a memory module, the faster it can perform operations, which results in faster processing times and better overall performance.
ECC Registered Dual Rank DDR3 SDRAM
The HPE 708639-B21 memory module is designed with ECC registered dual rank DDR3 SDRAM. ECC stands for Error-Correcting Code, which is a type of memory that can detect and correct errors that occur during data transfer. This is an important feature for servers because errors in data can cause system crashes or data corruption, which can be disastrous for businesses.
Registered memory is a type of memory that uses an additional register between the memory module and the memory controller. This register helps to reduce electrical load on the memory controller and prevents errors that can occur due to electrical interference. This results in more reliable and stable system performance.
Dual-rank memory is a type of memory that has two sets of memory chips on each module. This increases the memory density and improves the overall performance of the module. Dual-rank memory is particularly useful in servers that require a lot of memory for running multiple applications or virtual machines.
240-PIN DIMM Configuration
The HPE 708639-B21 memory module has a 240-pin DIMM configuration. DIMM stands for Dual In-line Memory Module, which is a type of memory module that has a series of pins on both sides of the module. The 240-pin configuration indicates the number of pins on the module, which determines the type of slot it can be inserted into.
240-pin DIMM modules are commonly used in servers and workstations because they provide a high level of performance and reliability. They are also designed to operate at higher frequencies than other types of memory modules, which makes them ideal for high-performance computing applications.
Genuine HPE Memory
The HPE 708639-B21 memory module is a genuine HPE product, which means it is designed and manufactured by Hewlett Packard Enterprise (HPE). Using genuine HPE memory modules in HPE servers is important because it ensures that the memory is compatible with the server and has been tested to meet HPE's strict quality standards.
Using non-genuine memory modules in HPE servers can cause compatibility issues and may result in system instability or data corruption. In addition, using non-genuine memory modules can void the server's warranty, which can be costly if something goes wrong.
In summary, the HPE 708639-B21 8GB memory module is a high-quality memory module designed for use in servers, particularly the Proliant BL460C Generation 8.

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.
