There are many places that take old memory for recycling. Staples and Office Depot both do. Wise recycling is a local facility that takes old computer parts.
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.
DDR SDRAM has one notch and uses 184 pins.
DDR
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
one notch
Sdram has one notch. Depending upon the model of Sdram the number of pins it has can vary but a standard Sdram has 184 pins.
There are plenty of places in order for one to purchase a 184 pin SDRAM. However, one might want to order from the website Amazon to have better prices.
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 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.
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.
No. SDRAM has two notches and DDR SDRAM has only one so besides all the electrical incompatibilities it won't physically fit.
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.
