 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 ddr into the motherboard''s documentation. 4-clock 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. ram 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 review of the memory module are. ddr All of our SDRAM DIMMs have SPD programming. The system BIOS should therefore be set on AutoDetection for memory. Where do you get your RAM? 4 All Memory.Com is your source for high-quality computer memory. We buy ram direct from major manufacturers and because we don''t pay a middleman we can offer our memory at great prices. 4 All Memory.Com carries Micron, Toshiba, Siemens, Kingston, Viking, PQI, and many other major manufacturers. We offer over 55,000 upgrades for more than 12,000 review different ddr computer systems. All of our memory is guaranteed 100% compatible with your system. We offer a lifetime warranty and we stand behind our products, period! Can I really install memory myself? The idea of opening up a computer''s case and fiddling around with its components might cause a beginning user to cringe, but this is one of the easiest upgrades ram you can do. You just have to turn the system off, ground yourself, open the case, and install the new RAM. You can go to our installation guide for more detailed instructions. Just click on the Help tab and then the link for "Installation Guides" Will memory from 4 All Memory.Com work with memory from another review manufacturer? Yes. You can mix and match modules from different ddr and ram manufacturers. Keep in mind that you should always install the largest module in the lowest numbered slot. RAM comes in many different review kinds of configurations and types-and runs at many different speeds, as well. Before you upgrade, you need to know 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 ddr they''re old. They come in pairs or sets of eight. Step 2: Single Inline Memory Modules SIMMs (Single Inline Memory Modules) plug into long, matching sockets on your motherboard. SIMMs have ram 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 review formats. 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 Would you like to find ddr, simm or dimm memory but aren't sure where to look? Search no further. We have any type of memory for any computer you have.
