RAM is Different · DIGIT-ARC

Please Guys clear my doubt about -

I don't know what's the difference between.. the different types of RAM -

DDR , DDR 2 , DDR 3 , and now DDR 4 ....

S

ddr - double data rate . working speed - ( all in Mhz )
ddr 1 -- 266 , 333 , 400
ddr2-- 533 , 667 , 800 (I think )
i think only ddr 1 & 2 are for mobo's ( to attach to mobo ) ram .
ddr3 and ddr4 are gddr's ( on ur graphics card )

ddr3 for mobo's are coming soon!

edit
ddr1 runs at 533mhz
ddr2 at 1066mhz also
Pl correct me if i am wrng! :wink:

I think only operating frecuency that matters...

DDR SDRAM, DDR2 SDRAM, and DDR3 SDRAM

thanks for correcting me . who cares what the no. of ddr is ? its the frequency . give more info abt dual channel and single channel .thanks again

ddr3 is a new thing that is going to come soon the mian difference is that ddr2 is faster than ddr and ddr2 can run at higher clock speeds than the ddr can run. I think in ddr the maximum speed is 400 or 533 mhz whereas in ddr2 there is uptil 800mhz stats from 533mhz. But there are new 1066mhz ddr2 rams coming up...

Thanks all of you guys but what the main difference some kind of chips etc....

their operating (or clock) frequency is the main difference

u need two identical ram sticks to run them into dual channel! (double of their normal bandwidth)

S

u mean , 2 * 512ddr400 = 1gb ddr800 ?

@pc_game_lover2004, why the hell use "[

]" so many times??? infact its not needed in your post, coz you want THE help.

looks like a great epic RAMayana
