 For example, dimm you can add PC800 modules to a system that was designed for modules, but the memory will run at the speed. How much memory do I need? Ask us and we will tell you every ounce and then a megabyte to spare. The answer really depends on how much and for what your system is used. Upgrading is easy and cost effective. RAM is used every time you open an application, download, play a game or simply turn on your computer. Additionally if you work with or plan to work with digital audio and video more ram is a necessity. The amount of memory you need depends upon how you use your computer. Most applications recommend a minimum of 64MB, and most users desire more than the minimum requirement. dimm Novice User / Administrative If you use your computer to send and receive dimm email, do a little word processing, and are starting to surf the Web, you can get by with 64MB. However, you would benefit from going to at least 128MB of memory. Basic User dimm / Student If you are spending more time surfing the internet, sending and receiving email, and doing word processing along with other applications, you can get by with 128MB, but would benefit from going to 256MB. The last step upon leaving the case should always be to ensure that every cable and power plug is fully seated. If this also does not resolve the problem, try just the new module alone in the system to determine if it is compatible with your system. If the system boots with just the new module, try shutting down and adding the other modules one by one dimm to determine if there may be a chipset incompatibility. What is the difference between ECC and non-ECC (non-parity) memory? If you are unsure of which type you have, just count the number of small black chips on one of your existing memory modules. If the number of chips divides by three evenly, then you need ECC. If the number of chips is does NOT divide evenly by three, you have non-ECC or non-parity memory. If you plan to use your system as a server or a similar mission critical type machine, you may want to take advantage of ECC. If you plan to use your dimm system for regular home, office, or gaming applications, you are better off with non-ECC. Current technology DRAM is very stable and memory errors are rare, so unless you have a need for ECC, you are better served with dimm non-parity SDRAM. EDO DRAM. Extended Data Out DRAM EDO speeds dimm are measured in nanoseconds. You can buy EDO as fast as 50ns for your personal computer main memory (you may see faster EDO DRAM on some graphics cards. EDO memory is commonly available as 72-pin SIMMs). FPM DRAM. Fast Page dimm Mode dimm DRAM Fast-page mode is becoming increasingly scarce, but, unless you''re running a very early system (430NX chipset or earlier) or a 486 system, you probably don''t want to get DRAM. Fast-page mode memory comes in SIMMs. RDRAM is shipped in RIMMs (RAMBUS inline memory modules). Future systems using the Intel 820 chipset and the upcoming 600MHz plus Pentium IIIs will use RAMBUS memory, but they aren''t out as of this writing. Way back in the dark ages of the PC architecture, I once owned an original Compaq portable. While the Compaq supported a whopping 640KB of RAM, it only came with 256KB. I upgraded my Compaq myself with an additional 384KB of memory by carefully inserting 27 individual 16KB RAM chips. The hunger for memory has steadily increased since then; 64MB is no longer unusual. Upgrading memory is easier, too; you no longer must painfully insert individual RAM chips. Would you like to find ddr, simm or dimm memory but aren't sure where to look? Search no further.
