RAM Types and Features | ddr2 2GB RAM Price in India

RAM is utilized for projects and information as well as by the working framework for circle storing (utilizing RAM to hold as of late gotten to data). Shop online ddr2 2GB ram price in India. In this manner, introducing more RAM further develops moves between the CPU and both RAM and hard drives. In the event that your PC runs shy of RAM, the working framework can likewise involve the hard drive as virtual memory, a sluggish substitute for RAM. 

Albeit the hard drive can fill in for RAM when absolutely necessary, don’t mistake RAM for mass capacity gadgets like hard circles or SSDs. Albeit the items in RAM and mass stockpiling can be changed openly, RAM loses its items when you shut down the PC, while attractive capacity can hold information for quite a long time. Despite the fact that RAM’s items are brief, RAM is a lot quicker than attractive or SSD stockpiling; RAM speed is estimated in nanoseconds (billionths of a second), while attractive and SSD stockpiling is estimated in milliseconds (thousandths of a second).

Consistently expanding measures of RAM are required as working frameworks and applications get all the more impressive and add more highlights. Since RAM is perhaps the most well-known move up to add to any PC or work area framework during its life expectancy, you want to comprehend how RAM functions, which sorts of RAM exist, and how to add it to give the greatest presentation lift to the frameworks you keep up with.

Memory Upgrade Considerations

At the point when you should indicate memory for a given framework, there are a few factors you want to be aware of:

Memory module structure factor (240-pin DIMM, 184-pin DIMM, 168-pin DIMM, 204-pin SO-DIMM, etc) — The structure factor your framework can utilize has an extraordinary arrangement to do with the memory update choices you have with some random framework. Albeit a couple of frameworks can utilize more than one memory module structure factor, much of the time to change to a quicker kind of memory module, for example, from 184-pin DIMM (utilized by DDR SDRAM) to 240-pin DIMM (like DDR2 or DDR3 SDRAM), you really want to redesign the motherboard first.

Memory chip type utilized on the module (SDRAM, DDR SDRAM, etc) — Today, a specific memory module type utilizes just a single sort of memory. Be that as it may, more seasoned memory module types, for example, mid-168-pin DIMMs were accessible with various kinds of memory chips. You want to determine the right memory chip type in such cases to stay away from clashes with locally available memory and give stable execution.

Memory module speed (PC3200, PC2-6400, PC3-12800, etc) — There are three methods for determining the speed of a memory module: the genuine speed in ns (nanoseconds) of the chips on the module (60ns), the clock speed of the information transport (PC800 is 800MHz), or the throughput (in Mbps) of the memory (for instance, PC3200 is 3,200Mbps or 3.2Gbps; PC2-2 6400 is 6,400Mbps or 6.4Gbps, and PC3-12800 is 12,800Mbps or 12.8Gbps). The throughput technique is utilized by current memory types.

Memory module dormancy — Latency is the means by which rapidly memory can switch between lines. Modules with a similar speed could have different idleness values. Every one of the modules in a bank ought to have similar idleness as well as size and speed.

Blunder checking (equality, non-equality, ECC) — Most frameworks don’t perform equality checking (to confirm the items in memory or right mistakes), however, some motherboards and frameworks support these capacities. Despite the fact that equality-checked memory mostly dials back the framework, ECC memory can identify memory mistakes as well as right them. 

In the event that a framework is performing basic work (like undeniable level science or monetary capacities or departmental or undertaking level server errands), ECC support in the motherboard and ECC memory are beneficial choices to determine. A few frameworks likewise support cushioned (enrolled) or nonregistered modules. Supported (all the more normally known as enlisted) modules are more solid however are slower on the grounds that they incorporate a chip that helps the memory signal.

Admissible module sizes and blends — Some motherboards demand you utilize similar velocities. Now and again similar sizes of memory in every memory attachment; others are more adaptable. To figure out which is valid about a specific framework, check the motherboard or framework documentation before you introduce memory or add more memory.

The number of modules required per bank of memory. Systems address memory in banks, and the number of modules per bank changes as per the processor and the memory module type introduced. In the event that you want more than one module for every bank, and just a single module is introduced, the framework will overlook it. Frameworks that require various modules per bank expect that modules be a similar size and speed.

Subsequently, frameworks running double channel memory offer quicker memory execution than frameworks running single-channel memory. Intel presented triple-channel memory (which runs much quicker than double-channel memory) with its Core i7 processor. Quad-channel memory, accessible on some superior execution Intel work area and server stages and AMD server stages, is considerably quicker.

Tiny impression frameworks, (for example, those that utilization microATX or Mini-ITX motherboards). This frequently support only a couple of modules, yet frameworks that utilization standard size ATX motherboards. Yet frequently support at least three modules, particularly those intended for multi-channel memory (at least two modules got to as a solitary coherent unit for quicker execution).

RAM Types

Essentially all memory modules utilize a unique RAM of some sort (DRAM) chips. Measure requires incessant re-energizes of memory to hold its items.


Static arbitrary access memory (SRAM) is RAM that needn’t bother with to be occasionally revived. Memory reviving is normal to different kinds of RAM. And is essentially the demonstration of perusing data from a particular area of memory and quickly revising that data back to a similar region without changing it. Because of SRAM’s design, it doesn’t need this invigorate. This implies that you likely will not be supplanting SRAM.


Simultaneous DRAM (SDRAM) was the main kind of memory to run in a state of harmony. With the processor transport (the association between the processor, or CPU, and different parts on the motherboard). Most 168-pin DIMM modules use SDRAM memory. To decide if a DIMM module contains SDRAM memory, really take a look at its speed markings. SDRAM memory is appraised by transport speed (PC66 approaches 66MHz transport speed; PC100 rises to 100MHz transport speed; and PC133 approaches 133MHz transport speed). All SDRAM modules have a the slightest bit prefetch cushion and perform one exchange for every clock cycle.


The second era of frameworks running simultaneous DRAM utilize twofold information rate SDRAM (DDR SDRAM). DDR SDRAM performs two exchanges for every clock cycle. Rather than one, similarly as with customary SDRAM and highlights a no-account prefetch cradle. 184-pin DIMM memory modules use DDR SDRAM chips.

Normal paces for DDR SDRAM incorporate PC1600 (200MHz/1600Mbps). PC2100 (266MHz/2100Mbps), PC2700 (333MHz/2700Mbps), and PC3200 (400MHz/3200Mbps). Yet different velocities are accessible from certain merchants.


Twofold information rate 2 SDRAM (DDR2 SDRAM) is the replacement to DDR SDRAM. DDR2 SDRAM runs its outside information transport at two times the speed of DDR SDRAM. This highlights a four-bit prefetch cushion, empowering quicker execution. In any case, DDR2 SDRAM memory has more prominent dormancy than DDR SDRAM memory. Dormancy is a proportion of what amount of time it requires to get data from memory; the higher the number, the more prominent the inactivity. Common inactivity values for standard DDR2 memory are CL=5 and CL=6, contrasted with CL=2.5 and CL=3 for DDR memory. 240-pin memory modules use DDR2 SDRAM.

PC2-demonstrates the module utilizes DDR2 memory; PC-shows the module utilizes DDR memory.

Other normal rates for DDR2 SDRAM modules incorporate PC2-3200 (DDR2-400; 3200Mbps throughput); PC2-5300 (DDR2-667); PC2-6400 (DDR2-800); and PC2-8500 (DDR2-1066).


Twofold information rate 3 SDRAM (DDR3 SDRAM). Compared to DDR2, DDR3 runs at lower voltages. It has two times the interior banks, and most forms run at quicker speeds than DDR2. DDR3 additionally has an eight-digit prefetch transport. Similarly as with DDR2 versus DDR, DDR3 has more prominent inactivity than DDR2. Average idleness values for standard DDR3 memory are CL7 or CL9, contrasted with CL5 or CL6 for DDR2. PC3-demonstrates the module utilizes DDR3 memory
