Product Information to 495604-B21 Memory Kit
The 495604-B21 is a memory kit designed for use in servers, specifically the Proliant DL360, DL380, and ML370 models. This kit is made by Dell and is capable of providing 64GB of memory to your server. It consists of eight 8GB DDR2 SDRAM modules, each with a speed of 667MHz. This article will provide a detailed explanation of what this memory kit is, how it works, and what benefits it provides.
DDR2 SDRAM Memory
DDR2 SDRAM, or Double Data Rate 2 Synchronous Dynamic Random-Access Memory, is a type of memory used in computers and servers. It is a second-generation version of the DDR memory type and was released in 2003. DDR2 SDRAM has faster data transfer rates than its predecessor and is also more power-efficient.
DDR2 SDRAM works by synchronizing with the system clock of the computer or server it is installed in. It transfers data on both the rising and falling edges of the clock signal, allowing it to transfer twice as much data per clock cycle as its predecessor. DDR2 SDRAM is also capable of operating at higher frequencies, allowing for faster data transfer rates.
ECC Memory
ECC, or Error-Correcting Code, is a type of memory used in servers and other mission-critical systems. ECC memory uses a special algorithm to detect and correct errors that occur during data storage and retrieval. This is important in servers because errors in memory can cause system crashes or other issues that can be detrimental to the performance of the server.
240-Pin DIMM Memory
The 495604-B21 memory kit consists of 240-pin DIMM memory modules. DIMM stands for Dual In-Line Memory Module and is a type of memory module used in computers and servers. DIMMs are longer and thinner than other types of memory modules, such as SIMMs or RIMMs, and have pins on both sides.
240-pin DIMMs are designed for DDR2 SDRAM memory and have a transfer rate of 64 bits at a time. They are also designed to be installed in pairs or sets of four, depending on the configuration of the motherboard or server.
Benefits of the 495604-B21 Memory Kit
The 495604-B21 memory kit provides several benefits to your server. The most obvious benefit is the increased amount of memory it provides. With 64GB of memory, your server will be able to handle more applications and processes simultaneously, resulting in better overall performance.
The speed of the memory modules, at 667MHz, also provides a performance boost. This allows data to be transferred more quickly between the memory and the processor, resulting in faster response times and better overall system performance.
The use of ECC memory in the 495604-B21 memory kit also provides a significant benefit. ECC memory helps to prevent errors and crashes caused by memory issues, resulting in increased system stability and reliability.
Finally, the use of 240-pin DIMMs allows for easy installation and maintenance. These modules are designed to be installed in pairs or sets of four, making it easy to add or remove memory from your server as needed. Additionally, the 240-pin DIMMs are designed to be hot-swappable, meaning they can be removed and replaced while the server is still running, reducing downtime and maintenance costs.
In Summary, the 495604-B21 memory kit is a high-performance memory kit designed for use in servers. It provides 64GB of memory using eight 8GB DDR2 SDRAM modules, each with a speed of 667MHz. The use of ECC memory ensures system stability and reliability, while the 240-pin DIMM design allows for easy installation and maintenance.

PC2-5300 memory
Are you looking for the best PC-5300 modules for your server or PC? Allhdd.com is your one-stop-shop for modules from top brands on the market. We have a wide range of memory kits you can choose from. Browse through our website for the best PC2-5300 modules for all your needs.
Double Data Rate (DDR) stands for Synchronous Dynamic Random-Access Memory (SDRAM). It is the typical type of memory that serves as RAM for almost all modern-day processors.
The DDR2 SDRAM (Double Data Rate 2 SDRAM) is the upgrade to DDR SDRAM. It comes with a four-bit pre-fetch buffer and runs its external data bus at double the DDR SDRAM speed to facilitate a faster performance.
Buying DDR2 SDRAM from allhdd.com is pretty much straightforward if you know the front-bus of your system.
There are a handful of features to look out for when choosing a RAM. Suppose you wanted to decide between RAMs of varying clock speeds. In that case, the RAM with a greater clock speed is better. However, when choosing between RAMs of identical clock speeds, the RAM with lower CAS latency will perform faster. Latency is a measure of how long it takes to collect data from memory. The higher this figure, the greater the latency.
The DDR2 PC2-5300 memory is generally regarded as DDR2-667. Its design and unique features work efficiently with systems featuring a 333MHz front-side bus, rendering a data transfer rate of 667MT/s.
The PC2 5300 RAM has a module bandwidth of 5300MB/s. This bandwidth is the highest amount of data the PC2 5300 transfers every second.
Depending on your preference and budget, there are various PC2-5300 memory kits and sizes you can buy here on allhdd.com. These include 4GB, 8GB, 16GB, 64GB, 32GB, and 128GB memory kits. All units are brand new and available at pocket-friendly prices.
Factors to consider before buying the PC2 modules
Your system's RAM is the single most crucial feature for a flawless performance. Hence, picking one requires some attention to certain factors.
- Frequency
You should know the frequency at which your server or computer motherboard operates. It is catastrophic to mount a memory with a lower frequency than the motherboard's minimum frequency. You risk damaging both RAM and your motherboard. Here are the typical speeds for DDR2 SDRAM modules:
PC2-6400 (DDR2-800)
PC2-3200 (DDR2-400 at 3200Mbps throughput)
PC2-8500 (DDR2-1066), and
PC2-5300 (DDR2-667).
- RAM Size
Depending on your hardware, the modern-day memory module size ranges from 4GB to 128GB. If your system performs a lot of multitasking daily, you'll need a bigger RAM size. You can buy all memory kits ranging from 4GB, 8GB, 16GB, 64GB, 32GB, and 128GB, 256GB, 512GB, 1TB, and more here on allhdd.com.
- DDR Generation
Motherboards that are built to support the newer generation DDR will not work with older generations. Be sure to figure out what works for your PC. A DDR2 memory module will not work on a motherboard that features a DDR3 DIMM slot. The same thing applies to other memory modules and DIMM slots.
- Number of Channels
Dual channels are the most preferred choice when it comes to the channel number. Say your PC needs 16GB; in that case, you can take a two 8GB memory kit in dual channel mode.

Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
