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.

  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 allhdd.com.

  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.
