Low Density Memory

  mrtreacle 21:08 11 Feb 2007


Completely baffled as to whether some memory i have been looking at for upgrade is low density or not
Its called Kingston Value RAM and has a description of

1GB DDR PC2700 333MHz 128x64 DDR 184pin KVR333X64C25/1G

The spec sheet also mentions 16 modules 64 x8

Can anyone confirm this is low density and/or confirm they have used this memory OK please ?

My motherboard is Microstar 6701 made for Medion (MD5000)and is shown as compatible on the Kingston site
But i am told low density is best

Help thanks in advance Richard

The density, high or low, of a memory module refers to the number of chips that are on that module. Different computers require the memory module to be built with a different number of chips. i.e. There is more than one way to build a 1 GB memory module.

All low density 1 GB modules are made with 16 chips (8 chips on each side) using 64Mx8 device whilst high density 1 GB modules are made with 16 chips (8 chips on each side) using 128Mx4 device.
Basically :-

Low density modules have 100% compatibility with ALL systems and ALL chip sets as they fully follow JEDEC ( Joint Electron Device Engineering Council ) guidelines.

High density modules only have 10% compatibility ( mainly designed for used in slower server chip sets ) and are very slow as they break all JEDEC guidelines and are usually about half the price when compared with low density modules.

Hope this helps
