Is pc5400 better than pc5300

What is the difference?? i am looking to buy a 4GB kit and what is the difference between the two? im guessing pc5400 is slightly better..

 

PC5400 & PC5300?
Difference? There is none its to different terms for the same thing.

 

There's literally no difference at all between pc5400 and pc5400 as your title asks.

But as ThomasH points out the difference between pc5400 and pc5300 are gimmicky marketing numbers that mean the same thing. It's somewhat like rounded up hard drive GB totals; some memory is sold rounded up to pc5400, some is sold rounded down to pc5300 but the speed is essentially the same.

 

yea.. well i read that regardless of 5400 or 5300, santa rosa will only read 667 mhz of the ram.. so it literally is no difference in my case.. thanks guys.

 

It will only read 667MHz because both 5400 and 5300 are the same exact speed (667MHz). There's no difference.

 

5400 RAM is supposedly tested at a frequency just a few MHz above 667...basically means nothing.

 

do you mean pc2-5300 vs pc2-5400?
No, there isn't any difference, it's just a marketing gimmick.
The true potential that your machine will use is only upto 667 MHz.... and the frequency at which the 667 MHz rated memory operates is 5333, which is normally rated as pc2-5300..., but some companies decide to rate them as pc2-5400 by testing modules at 675 MHz (doesn't matter as all your machine will use is 667 MHz)....

 

Out of curiosity, what are you going to do with 4gb of RAM I mean you'll only achieve 3.25 of it... Why dont u buy a 2gb stick and a 1 gb stick?

 

i do a lot of photo editing and what not.. oh and no.. i will be achieving all 4 gigs of it using vista 64 bit.. and on top of that. why 4 gigs instead of 3 gigs?? because i can!! i love santa rosa.. haha
