What is the Difference Between DDR1 DDR2 & DDR3?

What’s the confusion about RAM?
Many of the pc customers perform some research earlier than upgrading their system so that they precisely learn about a wonderfully matching CPU, motherboard and video card mixture that may meet all their wants. However most of them fail with regards to RAM. They simply know the dimensions of the RAM i.e. 1GB, 2GB or 4GB, however they do not know what this DDR1, DDR2 or DDR3 is all about. In order that’s why I got here up with a fool’s information for purchasing a RAM, as a result of it seems that choosing the right DDR variant is an important issue that determines how your general system will carry out, thus each pc person ought to be well-advised to study it.

DDR1 Specs
DDR-DIM (Double Knowledge Price DIMM or DDR DIMM), or most popularly simply plain DDR. Double Knowledge Price interfaces present two knowledge transfers per differential clock. The information turns into registered when the CK goes excessive [the + side], and /CK goes low [the – side]. DDR1 makes use of the JEDEC customary for Double Date Price [DDR I] SDRAM. Like all DDR RAM it’s out there as registered or un-buffered. Registered DIMMs are commonly known as FB-DIMMs and have their tackle and management traces buffered as a way to cut back sign loading. FB-DIMMs are significantly costlier than un-buffered DIMMs and are typically reserved for server use. There are only a few fanatic/prosumer/avid gamers using FB-DIMMs of their CPU’s. Un-buffered DIMMs do not function tackle traces and management line buffering, so that they value fairly a bit much less. Nevertheless, they could be system-loading restricted and are thus typically restricted within the quantity that may be fitted onto one system. You may discover that almost all un-buffered DIMMs today can solely be put in on one motherboard to a most of four x 1GB. Buffered or registered DIMMs haven’t got these limitations and server boards can accommodate eight x 1GB, 16 x 1GB or extra. An fascinating and largely unknown side of un-buffered DDR DIMMs is that they can function one clock cycle sooner then FB-DIMMs.

DDR2 Specs
DDR2 reminiscence is the second technology in DDR reminiscence. DDR2 begins with a pace stage of 400MHz because the lowest out there whereas the 400MHz pace is definitely the very best pace for DDR1. Due to this fact, DDR2 picks up the place DDR1 leaves off. It’s kind of unusual however attributable to completely different latencies a 400MHz DDR1 will outperform a 400MHz DDR2, however the benefit returns to DDR2 as quickly because the pace reaches the following step 532MHz, which DDR1 can’t attain.

DDR3 Specs
DDR3 is the third technology in DDR reminiscence. DDR3 begins with a lowest capability stage of 800Mbps and goes as much as 1600Mbps with bus pace as excessive as 2000MHz. Increased efficiency with decrease energy consumption is the most important profit, since working voltage is just one.5V for DDR3 in comparison with 1.8V for DDR2. Decrease warmth is generated, which signifies that techniques will run cooler. In the end the brand new know-how will end in greater capability modules: As much as 8GB modules (Utilizing 4Gb Chips) to assist decrease server/workstation system prices.

Prime Producers
Right here is the listing of A few of the main as shopping for a ram 8gb ddr3 from an unknown vendor would find yourself in guarantee points.


In case you comply with these pointers and completely analysis the right DDR to your system, you will be get pleasure from years of speedy and trouble-free computing. Somewhat little bit of examine is a small worth to pay!
