Ok, memory help.

post #1 of 23
Thread Starter 
Hey! I am wondering, even though millions of people have explained this to me trillions of times, I am still confused. Ok, what do the timings for ram mean? Also do you wnt the frequency of ram to be equal to the FSB of your cpu? Also, I am confused how you find the compatability between memory, and CPU. SUPER CONFUSED on all this. Could anybody help?

Ram timings are basically the amount of clock cycles needed to perform the respective operation. The lower the better, optimal ram timings are 2-2-2-5 (cas latency 2) with cheaper ram running about 3-3-3-8 (cas latency 3).

Your ram will automatically run at the speed of your fsb unless you manually change the divider (the ratio of the ram speed to your fsb), and technically even at a 1:1 ratio your ram will run twice as fast as your fsb because it is DDR ram (double data rate ram). To do basic overclocking you slowly raise your fsb (i.e from 200mhz to 205mhz). That will automatically raise your ram speed to 205mhz, but it will actually be running double that, so 410mhz or DDR410speeds, and your cpu core speed will increase (if you have a 10X multiplier, your new speed will be 10 X 205 = 2050mhz).

Yes it is, but that price is going to skyrocket about an hour before the auction ends.

Hey I got me another question:
What does the "PC3200" (any basic "PC" thingy) and what not mean when you are talking about RAM?

its the bandwith of the ram, 3.2 gigabytes per second. pc3200 is also called DDR400
cant complain..

OK well now i know that..but now, what makes this ram
http://www.newegg.com/Product/Produc...82E16820145450
Cost less than this ram?
http://www.newegg.com/Product/Produc...82E16820220006
Is it the latency? Because their CAS latency is both 2

mostly just brand. youll be able to find memory like that from a bunch of manufacturers. the patriots timings seems to be barely tighter but both are good. but the patriot comes with a 30 dollar rebate so its only 86 bucks
