Memory 256Mx8 or 512x8?

Good afternoon,

I want to buy a memory with chip organization (based on sixteen 128M x 8-bit). In the memory specification doesn't written about chip organization.

Which memory from the list is based on sixteen 128M x 8-bit components per module?

Memory list:

CML4GX3M2A1600C9

CMX4GX3M2A1600C9

CMV4GX3M2A1333C9

{

Memory controller (Intel® 4 Series Chipset Family):

The (G)MCH supports:

• DDR3 DIMM Modules:

— Raw Card A - Single Sided x8 un-buffered non-ECC

— Raw Card B - Double Sided x8 un-buffered non-ECC

— Raw Card C - Single Sided x16 un-buffered non-ECC

— Raw Card F - Double Sided x16 un-buffered non-ECC

DDR3 800 and 1066 Mhz

(Raw Card Version) (DIMM Capacity) (DRAM Device Technology ) (DRAM Organization) (# of DRAM Devices) (# of Physical Device Ranks) (# of Row/Col Address Bits) (# of Banks Inside DRAM) (Page Size)

A

512 MB 512Mb 64M X 8 8 1 13/10 8 8K

1 GB 1Gb 128M X 8 8 1 14/10 8 8K

B

1 GB 512Mb 64M X 8 16 2 13/10 8 8K

2 GB 1Gb 128M X 8 16 2 14/10 8 8K

C

256 MB 512Mb 32M X 16 4 1 12/10 8 8K

512 MB 1Gb 64M X 16 4 1 13/10 8 8K

F

512 MB 512Mb 32M X 16 8 2 12/10 8 8K

1 GB 1Gb 64M X 16 8 2 13/10 8 8K

}

P.s. Memory with the chip organization 512x8 doesn't supported by memory controler.
