 There are two ddrvsrdram 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 level 2 cache (also known as L2 cache) are all external ddrvsrdram 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 ddrvsrdram 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. As noted in the introduction, there''s a virtual alphabet soup of memory types: SDRAM, EDO, FPM, SIMM, and DIMM. It certainly can create a great deal of confusion. RAM itself stands for "random access memory," meaning the CPU can access any memory address without reading all addresses before it. (ROM—read only memory—is random access, too, but you can''t write to it). It gets worse, because memory comes in ddrvsrdram different speeds, and some types don''t work in some systems. Here''s the rundown on the three memory types used in today''s systems.... SDRAM. Synchronous DRAM SDRAM''s speed is typically measured in MHz (for example, 100MHz), ddrvsrdram although you do ddrvsrdram see references to 10ns SDRAM ("ns" stands ddrvsrdram for nanosecond or one billionth of a second). SDRAM for PCs comes in DIMMs. These refer to SDRAM DIMMs rated at different memory bus speeds. For any CPU running ddrvsrdram at a 100MHz bus speed you should get SDRAM. Some future motherboards will support SDRAM. Although there''s a price premium, ddrvsrdram SDRAM will run ddrvsrdram in a PC100 system.
