all4memory - cheap computer memory upgrades

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 all4memory 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" all4memory 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.

There are two types of cache in your computer: level 1 and level 2. The level 1 cache (also known as L1 cache) is inside the CPU itself, and you really have no control over quantity and speed. The all4memory level 2 cache (also known as L2 cache) are all external to the chip. The L2 cache on the nside the CPU package (though still external to the CPU chip itself). Those systems run on motherboards with a variety of core logic chipsets. However, some of them are designed so that the L2 cache only works with the first 64MB of RAM in your system. The two main culprits are the chipsets—two of the most common chipsets available. Now, 64MB is a lot of RAM, so it''s not like your system is somehow crippled (at least, not for gaming). But you should be aware that in the case of boards using these chipsets, more is not necessarily better. motherboards with the chipset probably can cache up to 512KB of RAM, but a few motherboard makers cheaped out and left out a critical TAG RAM chip and—you guessed it—those boards can only cache the first 64MB or RAM. To my knowledge, boards that use the can cache more than 64MB, but be wary.
