Memory

By nu4ever ·
This may be a stupid question but I get confused on memory as to what is what. Example EDO,MSD.RDRAM,DDRAM,etc. If anyone can help me it would be nice.
Thanks

EDO: Extended / Enhanced Data Out
Available in both 72 pin SIMM and 168 pin DIMM modules.
Usually 60 nS (66MHz)
EDO replaced FPM RAM.
(Fast Page Mode)

RDRAM: Rambus Dynamic RAM
Intel's dream for P3 and P4 systems.
For P4 systems, needed to be installed in matched pairs.
For P3, you needed pairs, or a continuity module.
While "technically" faster than DDR, even 800MHz RDRAM posted slower benchmarks than 200MHz DDR.

DDR-RAM: Double Data Rate RAM
184 pin DIMM modules and 144 pin notebook styles.
Also available in a special configuration for video RAM.
Nearly ALL system now use DDR RAM.
First used on Athlon processor based systems.

I am not familiar with MSD RAM.

hi
Go to www.dogpile.com, type in computer memory. Or type in the different types of memory, and it will show you a place where you can have it explained fully.

nowadays there is DDR isnt there.

DDR266/300/400(Mhz) or PC2100/2700/3200

DDR 400 or PC3200 is used in P4's with FSB of 800Mhz

you can look at it and see that:
p4s take DUAL CHANNEL ram (a pair) its like a balance:
2x400 = 800 (400 being RAM speed 800 Being FSB) it all adds up, thats y in overclocking you see the RAM speed goes up to keep the balance
