DDR SDRAM (double data rate synchronous dynamic random-access memory) units can be purchased from retailers specializing in computer parts. They can also be found on general retail websites, such as Amazon, Newegg, or eBay.
one notch
No. SDRAM has two notches and DDR SDRAM has only one so besides all the electrical incompatibilities it won't physically fit.
DDR SDRAM has one notch and uses 184 pins.
Sorry.. its either / or syndrome. If the motherboard, has DDR then it would be best to utilise this. As it is probably twice as fast as normal SDRam.
DDR and SDR have the names mentioned on the packing.You just need to read the packet.But if you don't have one then try reading on the ram chip you will find small initials on chip saying DDR with its number.
DDR
DIMM. Two types of DIMMs: a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Note that the SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has only one.
No, you can't use sd ram on a motherboard that specifies DDR memory and vice versa. It matters in terms of speed which type of memory you use, DDR is faster.
One can purchase PC133 SDRAM from a number of stores and online retailers. They can be purchased from Best Buy, eBay, Amazon, PC World and from Target.
DDR Memory modules have only one notch on the contact strip, positioned just off-centre. Hence DDR modules will not fit in an SD slot. SD Memory Modules have two notches.
DDR runs twice as fast as regular SDRAM, has one notch, and uses 184 pins. Instead of processing data for each beat of the system clock, as regular SDRAM does, it processes data when the beat rises and again when it falls, doubling the data rate of memory
There are many places where one can purchase a DDR PC2700. For example one can be purchased at Amazon or Best Buy. One could also be purchased from Crucial.
