This will improve power savings, especially with integrated graphics, if the CPU cores are in sleep mode but the IMC is still active.

PC2100 is used primarily in AMD® Athlon® systems, Pentium® III systems, and Pentium IV systems. The "2100" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 2100MB/s, or 2.1GB/s. PC2100 memory - which Crucial no longer carries - is DDR designed for use in systems with a 133MHz front-side bus (providing a 266 MT/s data transfer rate). PC1600 has been replaced by PC2700, which is backward-compatible. The "1600" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 1600MB/s, or 1.6GB/s. PC1600 memory - which Crucial no longer carries - is DDR designed for use in systems with a 100MHz front-side bus, (providing 200 mega transfers per second data transfer rate). The "8000" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 8000MB/s, or 8GB/s.

PC2-6400 is backward-compatible for PC2-4200 and PC2-5300.ĭDR2 PC2-8000 (commonly referred to as DDR2-1000) memory is DDR2 providing a 1,000MT/s data transfer rate). The "6400" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s. PC2-5300 is backward-compatible for PC2-4200.ĭDR2 PC2-6400 (commonly referred to as DDR2-800) memory is DDR2 designed for use in systems with a 400MHz front-side bus (providing an 800MT/s data transfer rate). The "5300" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 5300MB/s, or 5.3GB/s. The "4200" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 4200MB/s, or 4.2GB/s.ĭDR2 PC2-5300 (commonly referred to as DDR2-667) memory is DDR2 designed for use in systems with a 333MHz front-side bus (providing a 667MT/s data transfer rate). Here's a short summary of the most popular types of memory and what the numbers refer to.ĭDR2 PC2-4200 (commonly referred to as DDR2-533) memory is DDR2 designed for use in systems with a 266MHz front-side bus (providing a 533MT/s data transfer rate). But if you don't know a lot about memory, the numbers can be confusing. Rather than give memory modules catchy names, the industry refers to modules by their specifications. We recommend that you use either the Crucial Memory Advisor™ or Crucial System Scanner to find the right memory for your computer.

However, your system will operate at the speed of the slowest memory module installed. Memory is designed to be backward compatible within its generation, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. But before clicking that “buy” button on this or any website, it’s important to make sure the memory you are buying is compatible with your PC.ĭDR4 memory is the latest generation of memory for computing applications and offers many benefits over previous generations of memory including lower latencies, higher speeds, and more. One thing to keep in mind is that memory needs to be the same type - memory modules are not forward or backward compatible in terms of generation types so DDR3 will not work in DDR2 or DDR4.
