computer upgrade - cheap computer memory upgrades

EDO DRAM. Extended Data Out DRAM EDO speeds are measured in nanoseconds. You can buy EDO as fast as 50ns computer 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 Mode DRAM Fast-page upgrade mode is becoming increasingly scarce, but, unless you''re running a very early system computer (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.

FEATURES RAM comes in the form of a chip, and to increase memory, you simply plug additional chips in to slots on upgrade your computer''s main board. The capacity of a RAM chip is measured in megabytes, or millions of bytes. Most systems now come with 48MB of RAM and up. You should have at least 32MB of RAM for running Windows, but with the ever-growing demand for memory, 64 MB or higher is ideal. BUYING TIPS Before buying additional memory for your computer computer, consult the hardware manual that came with your computer. The manual will tell you what kind of memory is required for your system. It is also important to check the number of RAM slots in your computer, as there is a limited number on the main board for installing memory (anywhere from two to eight). You can only install upgrade as many memory modules as you have slots, so plan ahead. If you want to add or upgrade to 128MB of RAM, for instance, get a single 128MB RAM chip, not two 64MB modules. This will save you one RAM slot for future expansion.
