Different Speeds of Memory The faster the memory, the faster a computer operates. Memory comes memory rated at different speeds, and the faster the memory, the more it costs. Memory speed is measured in nanoseconds, and the lower the nanosecond rating, the faster the memory. For example, a 60 nanosecond stick chip is faster than an 80 nanosecond chip. Be sure that the memory memory you buy is as fast as the memory you''re replacing. Many newer, faster Pentiums come with RAM that can run at 100Mhz-the speed of the system bus. It’s always a good time to add random- access memory (RAM) to your stick computer. That’s because RAM is easy to install and can improve the performance of even the weakest computer. A couple of years ago, the average computer contained four megabytes (MB) of RAM. Now the standard is up to 16MB, with many new computers sporting 24MB or more. And users who play computer games or work with desktop publishing programs might have as much as 128MB of RAM.
What is the difference between 2-clock and 4-clock memory? Two types of SDRAM modules are the 2-clock and the 4-clock module. Structurally, they are the same, but they are accessed differently. A 2-clock SDRAM module is set up so that each clock cycle accesses two chips on the module. A 4-clock SDRAM setup accesses 4 chips per clock cycle. To choose what kind to get, you must look into the motherboard''s documentation. memory 4-clock stick modules are the more commonly used. The typical indication of the wrong type being used is a system giving error beeps and not booting as it cannot use the memory installed. The system will not proceed past POST (Power On Self Test). 2-clock was only used in 66 MHz systems. All PC 100 and PC 133 memory is 4-clock only. Do all of your SDRAM modules use SPD? SPD, or Serial Presence Detect, is a program in an EEPROM chip on the modules of SDRAM (Synchronous Dynamic Random Access Memory). It tells the system’s BIOS what the specifications and settings of the memory module are. All of our SDRAM DIMMs have SPD programming. memory The system BIOS should therefore be set on AutoDetection for stick and memory memory.
RAM comes in many different kinds of configurations and types-and runs at many different speeds, as well. Before you upgrade, you need to know stick how to spot the different types. Pictured in these steps are the different types of RAM, including the older-style DIPs and newer SIMMs and DIMMs. Step 1: Dual Inline Packages (DIPs) If you have an older computer, it might use an older kind of memory called a dual inline package (DIP). DIPs plug directly into their own sockets on the motherboard. It''s difficult to find DIPs today because they''re old. They come in pairs or sets of eight. Step 2: Single Inline Memory Modules SIMMs (Single Inline Memory Modules) plug memory into long, matching sockets on your motherboard. SIMMs have more capacity than DIPs. Typically, a motherboard has several banks of SIMM sockets into which you plug SIMMs. SIMMs come in 30-pin and 72-pin formats. stick 30-pin SIMMs usually have less capacity than 72-pin, and often come with capacities of 256K, 1MB, 2MB, and 4MB. 72-pin SIMMs come in 1MB, 2MB, 4MB, 8MB, 16MB, and 32MB. Step 3: Dual Inline Memory Modules
