VS1GB667D2, ASUS P5B Deluxe (intel 965) compatibility

Hi there,

 

do these modules work on ASUS P5B Deluxe? Because the mainboard manual says:

 

"This motherboard does not support memory modules made up of 128 Mb chips or double sided x16 memory modules."

 

from http://www.corsairmemory.com/corsair/valueselect.html

 

VS1GB667D2 PC-5300 1GB 128MBx64 240 DIMM

 

so are these modules build on 128Mb Chips and therefore incompatible?

 

Thanks a lot for your help and sorry for my bad english...

 

Bye,

Kai

OK, so what does the info in the organization column of this table mean then? What is an organization of 128MBx64, if it doesn't imply 128MB modules?

The 128MB you have noted is different from the 128Mb listed in the original post. Please watch the Memory Basics presentation:

 

http://www.corsairmemory.com/corsair/products/tech/memory_basics/153707/index.html

 

These terms deal with ranks and address width as opposed to specific IC density.

I've watched that presentation at least three times now. I understand what it's saying, but then again, obviously I don't completely understand it.

 

These terms deal with ranks and address width as opposed to specific IC density.

 

OK, but that appears to be a partial answer to my original question. Is the 128MBx64 supposed to imply all of the following? (FWIW, I can't see what if anything the "128MBx64" organization would say about rank).

  • The memory is logically accessed as 128*1024*1024 discrete data items, each 64 bits (8 bytes) wide.
  • There is only 1 bank.
  • The memory addresses for this DIMM are at least 27 bits wide implying row & column address widths of at least 14 bits.

Yes? No? Maybe?

its a bit complicated to explain and if you are really interested to understand I would suggest getting one of the guides from http://www.rojakpot.com

Thanks for the pointer. I'll take a look at it.

But the term 128M X 64 can mean a few things there need to be more information like what is the module part# you are asking about?

I was asking about the VS1GB667D2 in the subject of the OP. I was just wondering how to interpret the info in the "organization" column in this table on the Corsair website.
