Is 16x64 one-sided 128 mb PC133 SDRAM low density or high density?

[Salvador]

I'm trying to figure this out. Does anyone know for sure?

TIA,

Anyone know? I don't understand the 16x64 number. I need low density, but I'm not sure what this is.

BTW.. The part number for the RAM is P16M648YB7 - 75A. It has Spectek chips and is Kbyte RAM.

Thanks again.

hey sal, how ya doin?

about the ram. I was always under the assumption that single sided ram was high and double sided ram was low. but after reading a couple articles it kinda confused me.

one thing I think, is high density ram consists of 64mb chip and larger chips. (ie. you stick would have 2 chips on that one side instead of the 8 or 6 that it does)

hope someone can help you out better than I can!

High density is 16 chips(usually 2 sided). Low Density is 8 chips AFAIK.

That has 16 chips of 64Mb (megabit), 1 Megabyte = 8 Megabits, so 16 (# of chips) x 64Mb (chip size) / 8 is 128MBytes on the stick.
It is a double sided stick, 8 chips on each side, I believe.

I know.. I've read all the FAQ's too and I'm very confused myself. That's why I thought I would ask.

For clarification, there are 8 chips on this stick of RAM on one side.

Thanks again.

It could be either. Sorry

no for sure. x16 is low density, x4 is high density, x8 is low density as well.
8 chips at 128mb, that not low density per chip either

16x64 just means the module is 128MB, it doesn't tell anything the density.
In term of memory size, 8MB/chip is low density or 16MB/chip is high density, since it's single side, it must be 8 of 16MB chips.
In term of chip type, 16x8Mbit is low density, 32x4Mbit is high density.

This dimm could be either using 8 of 16x8Mbit chips or 8 of 32x4Mbit chips.
You've to see the number on the chip and search it from the ram manufacturer website.
