what is the differance between high density ram an low density ram?

Question

is one better than the other or is it just user preferance?

Answer 1

Here's a bit of information that I found comparing High Density RAM to Low Density RAM.

It costs memory manufacturers almost the same to produce Low Density modules which have 100% compatibility with all systems on the market, comparing to producing high density modules. So why would manufacturers be so foolish to produce high density modules which only have 10% compatibility with systems on the market? The reason is simple, because high density modules are mainly manufacturing process rejects/seconds that cannot be made as a low density modules. It is very much like Intel CPU, those CPU that cannot be made as Pentium 4 CPU become a slower bus Celeron CPU instead, by a down-binning process.

In short:-
LOW DENSITY modules have 100% compatibility with ALL systems and ALL chipsets.
HIGH DENSITY modules only have 10% compatibility.

The link for this is given below.

Answer 2

Not sure about density???? But RAM vary in type DDR1, DDR2,DDR3 and some old SDR's etc. These different types will only wok on the motherboard they are designed for. Check your RAM type, most common is DDR1, you may just see it as DDR RAM, find your FSB speed and match the RAM specs to this.

Answer 3

High density is better than low density low density can be 100mhz high density can mean 400mhz.

Answer 4

Eh... the density? I guess...
