About RAM Types
There are several types of RAM (Random Access Memory), ie, FPM RAM, EDO RAM, SDRAM, DDR and Rambus RAM. If you may not understand the type of RAM, then you may be able to read this article.
FPM RAM (Fast Page Mode DRAM)
Fast Page Mode DRAM DRAM is the oldest model. Problem that often arises from FPM DRAM is a slow transfer speed the maximum 50MHz.
EDO RAM
EDO RAM can provide the performance of the system 50% faster than the DRAM. EDO RAM as FPM DRAM, with some built chace to chip. Like FPM DRAM, EDO RAM has a maximum speed of 50MHz EDO RAM uga should require L2 cache to make everything run faster, but if the user does not have it, the EDO RAM will run much more slowly.
SDRAM (Synchronous DRAM)
Almost all systems use voltage 3.3 volt, 168-pin SDRAM DIMM is. SDRAM is not an extension of the series EDO RAM is a long time, but it is a new type of DRAM. SDRAM running start with the transfer speed 66MHz, while page mode DRAM and EDO akan longer running in the 50MHz maximum. SDRAM can now run at speeds of 133MHz (pc133), and bakan up to 180MHz or higher. To speed up the performance of processor, RAM and the new generation, such as DDR and RDRAM are usually able to support better performance.
DDR (Double Data Rate SDRAM)
DDR is basically transfer speeds have doubled from the SDRAM. DDR will operate in the 333MHz, 166MHz with the actual operation of the * 2 (aka PC333 / PC2700) or 133MHz * 2 (PC266 / PC2100). DDR RAM is also compatible with SDRAM physically, but uses the same parallel bus, so that makes it easier implemnetasi than RDRAM, which is a different technology.
Rambus RAM (RDRAM)
Besides the price is quite expensive, Intel RDRAM provide for customers, and is a popular choice for the Intel Pentium 4 memory. RDRAM is a serial memory technology that comes with three options, ie, PC600, PC700 and PC800. PC800 RDRAM is designed with a double maximum transfer speed of PC100 SDRAM, but have high latency. RDRAM has a multi-channel, such as the Pentium 4 motherboard, which can offer a good memory function, especially when paired with PC1066 RDRAM memory.
