Questions about RAM memory?
2) Can we use two different kind of RAM in one computer or are they compatible with each other?
3) What would happen if we put 2 different kind of RAM in one computer?
4) What are the criteria to choose any particular kind of RAM?
Answer:
RAM comes in several forms. The most common difference between these forms is how the RAM actually works and how much data it can read or write at a time. The main types are SDRAM, DDR, DDR2, DDR3. There are other kinds of RAM but they aren't typically used in home computers.
You must get the proper kind of RAM for your motherboard. RAM also has different number of pins. Obviously you need the correct number of pins if it is going to fit. Although the kind of RAM you get affects how much data can be written at a time, there is also something called a memory clock. This specifies how many times the RAM can perform RW (read/write) operations in a given time. This is measured in megahertz (Mhz) much like your computers CPU.
Each RAM module (stick of RAM) has a specific name depending on its type. For example...
PC-1600: DDR RAM that operates at 100 Mhz (1.6 GB/s)
PC-3200: DDR RAM that operates at 200 Mhz (3.2 GB/s)
PC2-3200: DDR2 RAM that operates at 200 Mhz (3.2 GB/s)
PC2-6400: DDR2 RAM that operates at 400 Mhz (6.4 GB\s)
The first part of the module name, specifies the type of RAM (SDRAM, DDR2, DDR3) while the number specifies how fast the RAM is. The higher the number, the more clock cycles the memory can do in a second.
I know this is complicated, but there is a lot to know about RAM. To review,
It MUST:
- have the proper number of pins for your motherboard
- be the same type (DDR, DDR2, DDR3)
- be greater than or equal to the maximum speed your motherboard can support
On the last point, you can put a PC2-6400 module in a PC2-4200 compatible motherboard, but it will operate at a slower speed than the module can support. However, you can NOT put PC2-4200 in a faster PC2-6400 compatible motherboard. The memory must be greater than or equal to in speed of what the mobo supports or it won't work.
You can put two different modules of RAM that operate at different speeds on the same motherboard, but it isn't recommended because of performance issues. The best way to buy RAM is to get what is called a "dual channel kit". This kit has the exact same two modules. If your motherboard supports dual-channel memory, you will see a large increase in performance than if you were to just throw different modules of different speeds on to the motherboard.
oh the worst thing that can happen is that your computer will blow up dont worry you will get hurt :P
1) Most available is SD RAM and DDR in various sorts
2) No. One type doesn`t usually work with another, due to different power / speed requirements
3) one set wouldn`t work.
4) What do you have for budget, what types are supported by your mainboard, how much do you need (what type of applications)
All choices must be made using each Motherboards memory requirements
There is different ram. And its important that you get the same kind and speed.
1). There are different kinds of ram available.. SD ram, DDR ram DDR2 rams widely in the current market.
2). U cannot use them together as they are not compatible..
3). If u put two different rams together only one ram is suppose to work.. the ram inserted wont work and will be useless..
4).Depends what kind of work you want to do.For gaming purpose u need faster rams like DDR2. for programming purposes u need large quantity like 2 gb or 4gb, the speed doesnt really matters that much. But to be true i would choose 1gb DDR2 ram instead of 4gb or 2 gb of DDR ram.
any querries mail me back.. vachhaninimit@gmail.com
1) What are different kind of RAM memory available in the market right now ?
DDR (bus speeds: PC266; PC333; PC400)
DDR2 (Bus Speeds: PC533; PC 667)
2) Can we use two different kind of RAM in one computer or are they compatible with each other?
No. You can't use two different kinds of RAM in one motherboard. They are compatible if they are the same kind and same bus speeds.
3) What would happen if we put 2 different kind of RAM in one computer?
You computer won't work properly (it hangs very often) or not at all.
4) What are the criteria to choose any particular kind of RAM?
1. Compatibility
a) Check your motherboard specs (RAM Type, Size, Bus speed)
b) Check existing RAM Specs (Brand, RAM Type, Size, Bus speed)
2. Brand: If you can afford it choose a good brand not generic ones
