what should we check at time of purching (assembled) system?

Question

How to select Mother Board, CPU, RAM?
Which hardware or internal setting of hardware is responsible for computer speed?

Answer 1

Tim M's answer pretty much covers everything, just a couple of his points I want to add onto.

3. The FSB is determined by the processor, not the motherboard. However this is a common mistake a lot of people make.

5. Memory does need to correlate to FSB speed, but does not need to be the exact same. The quoted memory speed should be 1/2 of the quoted FSB speed, or higher. I could go into a long technical explanation of why, just trust me though. This only applies on Intels, since AMDs will not have a FSB speed. Lastly, make sure to get the right type to fit your motherboard (DDR or DDR2).

Also, if you are looking to be a prebuilt like a Dell or HP, and we have totally misunderstood your question, just send me an email and I can be of some help.

Answer 2

System performance is determined by a combination of things. When you assemble a computer, the first decision you make is cpu/motherboard combination.

1. What type of processor do you desire (single core, dual core, Intel, AMD)?
2. What clock speed do you desire (pick a range right now rather than actual speed).
3. Select a motherboard that supports the type of type of cpu you've chosen. In addition, look at the bus speed (FSB). The higher the FSB number, the faster data moves between your processor and other components like memory, disk subsystem, video subsystem, etc.
4. You also need to make sure your motherboard has other features that you're looking for (# of PCI express slots, number of memory slots, USB and/or firewire ports, integrated network or audio)
5. Once you've chosen that, select memory. How much total memory you need depends on the types of applications you run and how your work style (running multiple apps simultaneously). The type of memory is dependent on the motherboard you selected. Match memory speed to FSB speed. Select DIMM sizes depending on how many memory slots the motherboard has factoring in your desire to upgrade in the future.
6. Next select video card. If you're not gaming or doing anything graphics intensive, integrated graphics may work fine for you. Otherwise, do research into your video requirements (e.g. what kind of games do you plan on playing)
7. select hard drive. SATA3 is fast, look for avg seek time, warranty. select capacity based upon what you plan on doing (if you're video editing, you'll need a lot of disk space)

The rest (optical drive, sound card, etc) really boil down to functionality rather the performance. Good luck.

Answer 3

The RAM and Proccessor is responsible for computer speed.

before purchasing an assembled computer, see if each parts are compatible to each other.

Example. If your RAM is DDR, your motherboard should have DDR slot.

Make sure also that your processor is supported by motherboard.

Answer 4

The post below pretty much cover it all. I would be asking myself what I want to do with the computer. Do I expect to play graphic intensive games? do lots of video editing? or do I plan to use it for Internet use and spreadsheets. This will give you a better picture of how much you need to spend in order to achieve your objective. Most people will buy the fastest computer they can afford, when they could save a few bucks and purchase smart according to what it is that you want to do with the computer. Hey, with the money you save, you can buy that new digital camera that you have always wanted. good luck!

Answer 5

computer speed is a combination of processor speed, memory speed, and storage speed.

The latest CPU offerings are Intel's Core2Duo and AMD's Athlon 64 X2.

The CPU is often the common way to determine speed for non technical folks
