High Density ram, I've found, is much cheaper than low density but it has compatibility issues. Now I could have 2 gigs of memory in my PC for less than $50 if my system will support High Density memory but I've had no luck in finding this, can somebody here tell me (for sure) if it will?
Motherboard: Gigabyte K8NS-Pro Socket 754
Processor: AMD Athlon 64 3200+ 2.2ghz
RAM Type: PC2100, 2700, or 3200 DDR supported, 1gb/slot max, 3 slots

I've never heard of high-density/low-density RAM O.o

This should explain it: DDR SDRAM - Wikipedia, the free encyclopedia

Oh, well, depends what size, if you have a 2Gbs chip, it'll be high density, if it's 512Mbs, it'll be low density, but you can't buy High or Low density RAM, you don't really have a choice, manufacturers always go with the cheapest/best option though, and yes, all motherboards support high/low density RAM, provided the module type is one supported by your motherboard, i.e. PC3200, PC6400,...

I'm sorry but that's incorrect. High Density memory refers to the way the chips are set up, for example, a High Density 1gb stick will be expressed as 128x4 while a Low Density stick will be 64x8. It's been said that High Density ram is supported by only 1 out of 4 modern motherboards, I want to know if mine is one of them.
The term has nothing to do with the size of the stick

Well yes it does, I think you'd be hard pressed to make a 2Gbs stick with only 32mbs chips

I don't know where you found the information that only some motherboards handle high density ram, all it is is bigger/smaller chips on the module
