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.
184-pin
184-pin DIMM
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 cannot the ECS P4VXASD2 supports the following:Two 184-pin 2.5V DDR SDRAM (DDR266/DDR200) Maximum: 2GB DDR or SDRAM (Buffered) / 1GB DDR or SDRAM (Unbuffered)
This is some specification for RAM modules: DDR3 240-pin DDR 2 240Pin DDR 184 Pin SDRAM 168-pin SODIMM 200-pin DDR2 SODIMM 200-pin DDR,DDR2 and DDR3 have 2 holes SDRAM have 3 holes
Common types of DIMM Memory Modules used in computers are a 168 pin SDRAM Module, or a 184 pin DDR SDRAM. These boards are designed to be used in personal computers.
DDR
A DIMM is based on two different pin counts. SDRAM has 168 pins and is an earlier generation of RAM. DDR RAM has 184 pins. Both are considered DIMMS.

While 184-pin DIMMs and 168-pin DIMMs are approximately the same size, 184-pin DIMMs have only one notch within the row of pins
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.
