Let's take a closer look at each of these specifications.

Capacity: The IBM 46C7420 has a capacity of 8GB, which is a significant amount of memory that can be used for a wide range of high-performance computing applications.

Speed: The memory module operates at a speed of 667Mhz, which is a relatively high speed that ensures fast data transfer and processing.

Memory Type: The IBM 46C7420 is a DDR2 SDRAM memory module. DDR2 SDRAM is the second generation of Double Data Rate Synchronous Dynamic Random Access Memory, which is an advanced type of memory that is used in modern computer systems.

Pin Count: The IBM 46C7420 has a pin count of 240, which is a standard for DIMM (Dual In-line Memory Module) memory modules.

Rank: The IBM 46C7420 is a Quad Rank memory module. Rank refers to the number of independent sets of DRAM chips on a memory module. Quad Rank memory modules have four sets of DRAM chips, which allows for higher capacity memory modules.

Error Correction Code: The IBM 46C7420 is an ECC Registered memory module, which means that it has the ability to detect and correct errors that occur during data transmission. ECC memory is commonly used in servers and other mission-critical computer systems where data integrity is of utmost importance.

Voltage: The memory module operates at a voltage of 1.8V, which is a relatively low voltage that makes it an energy-efficient choice for computer systems.

CAS Latency: The IBM 46C7420 has a CAS Latency of CL5. CAS Latency is a measure of the delay between the time a memory controller sends a request for data and the time the data is actually available to be used.

Form Factor: The IBM 46C7420 has a DIMM form factor, which is a type of memory module that is commonly used in desktop and server computer systems.

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.

PC2-5300 memory

Are you looking for the best PC-5300 modules for your server or PC? 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 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 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.

  1. 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).

  1. 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

  1. 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.

  1. 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. offers all the top-range memory modules from well-known brands.
