What is single sided and double sided?

This means...that only a small cross section is compatible with DH55TC and my current Kingston 1333D9 RAM?

Single- vs double-sided merely refers to how the chips are stuck on the PCB and has some implications for the controller and the connections on the PCB. Used to be an issue in older boards, this one is just pointing out that it's not an issue on that specific board.

Not sure whether you are referring to the physical cross-section of the RAM module or a cross-section of available modules on the market.

I meant the ones available on the market. Since its not an issue, I'll try to go ahead and buy some Kingston RAM to add as my other one is no longer sold

Modern x86 platforms use 64-bit memory buses, with each bus called a channel (so a dual-channel platform has two 64-bit buses). Each SDRAM memory bus is a multi-drop configuration in which one or more ranks share the bus but only one rank is ever active at a time. Each rank is a collection of SDRAM chips that have a common chip select (the signal that activates the chips) and form a 64-bit data bus. On personal computers the most common rank configuration by far is 8x8-bit, 8 chips each with 8 data pins are connected together into a rank. Typically, these chips are organized nicely on to one side of the DIMM's PCB. Multiple ranks can be placed on the same DIMM; the easiest way to do this is to organize a second rank onto the opposite side of the PCB. These are marketed as 1Rx8 and 2Rx8 referring to single-rank DIMMs constructed from 8-bit SDRAM chips and dual-rank DIMMs constructed from 8-bit SDRAM chips.

Embedded systems often use 16-bit SDRAM chips as these provide greater data width with a smaller physical footprint.

High end servers and workstations sometimes use 4-bit SDRAM chips as these can provide incredibly levels of installed memory.
