Where do you get your RAM? 4 All Memory.Com is your source for high-quality computer memory. We buy 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 different 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 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 manufacturer? Yes. You can mix and match modules from different manufacturers. Keep in mind that you should always install the largest module in the lowest numbered slot.

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 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 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 non-parity SDRAM.

what is Rambus Memory? Rambus is a chip to chip interface design that is system wide, allowing up to 800 MHz transfer rates. It allows data transfer through a simplified bus that operates in a high frequency range. Rambus uses a low voltage signal swing with data transfer on both edges of a synchronizing clock pulse. The Intel Pentium IV CPU is designed to take full advantage of this new, extremely fast memory design. What is DDR Memory? DDR memory, or Double Data Rate memory, is an evolutionary new memory technology that doubles the data through put to the processor, or CPU. It is an evolution of SDRAM, which leverages the existing production and environment to provide higher PC performance. What is meant by Registered memory? "Registered" is a means of "Buffering" the memory in SDRAM. This means that the clock signal is boosted across the entire array of memory chips so that the computer sees a clean sharp clock signal instead of a weakening clock signal as it progresses along the length of the memory path. Registered memory must be supported by the system board and cannot be mixed with "Unbuffered" modules. You must have only Registered memory to use Registered memory.
