Types of DIMMs are DDR3 and DDR2 that have 240 pins, DDR DIMMs with 184 pins and SDRAM DIMMs with 168 pins.
168
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
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.
Generally i believe they had 32 pins. I think they had some more recent revisions that had like 64 or something, but generally they were 32.
KVR800X18/256 is RDRAM. It's specs are: Memory Type: Rambus RDRAM Capacity: 256 MB Pins: 184 Bus Type: PC800 Error Correcting: Yes ECC Memory Speed: 40 ns Data Transfer rate: 800 Mhz Voltage: 2.5 volts.
DDR2 DIMMs have a total of 240 pins. The pin configuration includes a notch on the bottom edge to ensure proper alignment when inserted into a motherboard. Pins are arranged in two rows, with specific pins designated for power, ground, data, and control signals. DDR2 also features a different keying mechanism compared to its predecessor, DDR, to prevent incompatible installations.
DIMMs have 168, 184, or 240 pins on the edge connector of the board and can hold from 8MB to 2GB of RAM. Info from my A+ book.

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.
RDRAM stand for Rambus Dynamic Random Access Memory. (by RADA)
Rambus Dynamic Random Access Memory is the full form of RDRAM.
