Help! -ram Question

OK before I start my knowledge of computers is like cars, I can drive ok and know how to push and turn all the knoobs, switches and buttons but if I have to put in gas I have to call the AA, and as for the engine I have no idea which elastic band to wind up. In other words I ain't got much of a clue. :rolleyes:

SO with that in mind I have a qustion re RAM, I am looking to add some to my setup but when I look at the prices I am not sure what half of the details mean.

Can somebody explain what the figures here mean and how compatibility affects my choice please

The advert shows stuff like..

256MB PC133 SDRAM
256MB 266 PC2100 DDR
256MB 333 PC2700 DDR

I get the 256MB bit but that is about it, if someone could take the time to explain the other bits it would be much appreciated. Thanks in advance. Zero :blink:

pc 133 is really crap RAM and means its rubbish quality and cheap

basically the higher the number the better it is i think pc3200 is the best at the moment with 133 being the worst

SD = single data which isent too bad but you want DDR.DDR = Double Data Rate which means it processes everything at twice the speed so really you want to try and get DDR
poor ram = pc 133SD
average = pc2100DDR
good = pc2700DDR
Excellent = pc3200DDR

PC2100 DDR RAM has a maximum theoretical memory bandwidth of 2100MB/sec.
similarly, PC2700 has a maximum of 2700MB/sec

form what i remember you have a P4 2.54GHz, Zero Cool, so you should be looking for PC2700 or above ram.
as paul NFFC says, the higher the number the better, in your case.

you cannot use SDRAM in your computer, your motherboard will not support it

Thanks a lot fellas, the help is much appreciated :D

2gN - thanks again for your initial help, I was just curious why you had made your earlier recommendation, I just wanted to know if there were alternatives and what they were and why etc etc.

Thanks again folks :D :D

Yes, Somebody can. :lol:

You would be best to check what type you currently have. Open your PC case and look for slots near your CPU. There should already be a memory module there. (looks like a thin circuit board with chips all in a row.) Take a good look at the module. There is usually a sticker that identifies what type it is.

Sorry pal I&#39;ll watch my wording the next time :D :D

Thanks for getting back to me, with the help that I have had I have a fair idea of what I am looking for. :) Thanks agin for getting back to me. :D :D
