Computer Memory?

Question

is a computer contains DDR memory with support for
DDR PC2700,
DDR PC3200,
DDR PC4000 speeds

When shopping for new memory, do the PC numbers above make a difference, and if so, in what way ?

e.g. will PC4000 make my computer the fastest out of all 3 of them ?

Answer 1

Unless your gaming the PC numbers wont make much of a difference. Yes 4000 is quicker than 2700 but in day to day applications you wont notice it

Answer 2

ALL of those will work on a ddr slot. BIOS will just adjust speed and timings to default settings that the motherboard supports.

With regard to PC-4000, most motherboards will run it at PC-3200 speed. You will get the higher speed benefit when you overclock fsb. PC-4000 has a higher overclocking headroom than PC-3200.

Answer 3

some ram will "dumb" itself down to a slower bus speed pc2100 and pc2700 are a good example of that. if your motherboard requires pc2100 you can put pc2700 in it and it will slow itself down to 2100 speeds.. it doesnt however work the other way.. if your MB requires pc2700 you cant give it pc2100.. the best thing to do is go to the motherboards website and see what they recommend using.. you can also go to http://www.crucial.com/ and search for your manufacturer for the right ram..

Answer 4

Yes PC4000 will be the fastest ram your computer will support. It run's at 500MHz, while PC2700 run's at 333MHz, and PC3200 run's at 400MHz. What do you think of TigerDirect's ram offering's? http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=147

Answer 5

You will need to see what RAM is suitable for your computer.

Yes the higher the number the faster the access etc.

Have a look at Crucial's website first to see if the faster RAM is supported by your motherboard..
