What is the difference btw SDRAM and DDRAM?
I want to know wahat actually differentiate SDRAM and DDRAM both in function as well as physical differences.
Also, I like to know the difference btw SIM and DIM
waiting for reply frm You.
Thanks.
Heyy friend,
SDRAM stands for Synchronous Dynamic Random Access Memory. DDR is short for "DDR SDRAM" and stands for Double Data Rate. Nowadays to awoid misuderstandings SDRAM is often spicified as SDR SDRAM and SDR stands for Single Data Rate by analogy with DDR. Therefore, the main difference between SDR and DDR memory the doubled speed: DDR can transfer data at roughly twice the speed of SDRAM. For example, PC133 SDRAM runs at 133 Mhz, while 133 Mhz DDR effectively runs at 133 Mhz x 2 = 266 Mhz.
SDRAM has 168 pins and two notches at the connector, which prevents it from being used in a DDR SDRAM motherboard and vice versa. It comes mainly in PC66, PC100 and PC133; the bus speeds of the RAM in MHz.
DDR SDRAM has 184 pins and a single notch at the connector. It comes in speeds of PC1600 (166 MHz), PC1800 (200 MHz), PC2100 (266 MHz), PC2700 (333 MHz), PC3200 (400 MHz), and PC4400 (550 Mhz). The numbers represent the theoretical maximum bandwidth of the DDR SDRAM in Megabytes per second (MB/s). For example, PC2100 has a theoretical maximum bandwidth of 2100 MB/s.
The name given to this component is a good indication of the importance of it. It's called the mother-board; it's the component that all the other components link to in order to create a fully functional computer system. It's designed to make sure that all the additional components work together in harmony to achieve the goal of optimal performance.
If you're interested in buying a new motherboard, then it's important that you know a thing or two about the basic features that will form a significant part of your systems configuration.
It's good practice to know which Central Processing Unit that your want to buy before you select a motherboard. Once you've selected your CPU make sure that the motherboard you choose is able to support it and is able to have your CPU running at optimal performance levels.
It's very important that you're aware of the socket type that the motherboard you choose has. There are some socket types that have fairly limited processor support; if you're ever interested in upgrading later. But the general consensus is that, if you purchase a motherboard with a socket type that supports Pentium 4 Processors, it'd typically be either a Socket 478 or 423, for AMD processors on the other hand, it can vary quite significantly.
Another important aspect of your motherboard is the drive and memory formats that it supports. The memory formats that it may support are DDR2, DDR3, DDRAM or SDRAM and the Hard Drive formats are SATA, SATA2 or ATA. So make sure you choose one that supports the kind of hard drive and memory modules that you'd like to put inside it. The chipset of the motherboard typically determines the type of memory that it's compatible with.
It's important that you check the reviews of any motherboard that you may be interested in buying before you actually make the purchase. You can visit the websites of these motherboard manufacturers in order to find additional information related to the board that you're currently interested in. On the manufacturers website you should be able to download manuals which you can use to verify the different features and compare them to various other brands.
For best practice, it's very important that you consider everything that I have written above and make it a priority of yours to get as much information as you possibly can in order to ensure that you end up with a motherboard that suits your needs.
