Know About The DDR Memory To Get Best For Your PC
First of all, we need to know what is DDR memory? DDR SDRAM (double-data-rate synchronous dynamic random access memory) is a type of fast computer memory. It works faster than "single data rate" SDRAM and transfer twice the data without increasing the clock frequency. DDR RAM transfers data on both the rising and falling edges of the clock signal. It comes in various speeds and capacity and consumes less power than the conventional SDRAM.
It is also very important of us to know that different motherboard support different specification of memory modules. So, it becomes very important to know about the various types of DDR memory that are available in the market and comes from different memory manufacturers.
The most common types of computer RAM that are used in PCs are:
- Double Data Rate DRAM (DDR)
- Double Data Rate 2 DRAM (DDR2)
- Double Data Rate 3 DRAM (DDR3)
DDR1 memory
DDR (Double Data Rate) interfaces provide two data transfers per differential clock. The data becomes registered when the CK goes high and low. Like all DDR RAM it is available as registered or un-buffered. DDR1 memory has their address and control lines buffered in order to reduce signal loading and is considerably more expensive than un-buffered DIMMs. Unbuffered DDR1 can only be installed on one motherboard to a maximum of 4 x 1GB. Buffered or registered DIMMs don't have these limitations and server boards can accommodate 8 x 1GB, 16 x 1GB or more.
DDR2 memory
DDR2 memory, the second generation in DDR memory begins with a speed level of 400MHz, which is actually the highest speed for DDR1. Now this is interesting to know that because of different latencies a 400MHz DDR1 will serve better than a 400MHz DDR2, but DDR1 cannot compete with DDR2 as the speed goes higher (533MHz).
DDR3 Memory
The Third generation of DDR memory is DDR3, it begins with a lowest capacity level of 800Mbps (400MHz) and goes up to 1600Mbps. It gives higher performance with lower power consumption. DDR3 speed runs at two billion data transfers per second.
Not only it is important for us to know about the RAM but also it is equally important to know about the motherboard. Without know the compatibility of our motherboard we cannot find suitable RAM for our system. It is advisable to use memory selector or system scanner to find compatible and matching computer RAM for your system. Besides compatibility, do compare different brands available and their prices

(SALE)512 MB DDR II-SDRAM Module (667MHz)?
HP DRAM Memory EM993AA
Product name 512 MB DDR II-SDRAM Module (667MHz)
just RM100
who want to buy this RAM? contact me zlsho@hotmail.com/ zlsho@yahoo.com
it is DDR2 SD RAM. new one.
Sorry but buying that RAM is pointless since 1GB DDR2 RAM is $15-$20 bucks now. That's new ram too.
DDR2 is just too cheap to re-sale. You would have better luck if it was DDR.
Samsung is mass producing 4-Gbit DDR3 DRAM
