256 mb memory turns into 128mb

[fhlin]

Hi,

Recently i purchased 3 sticks of 256 mb pc-133 ram. but as i test them, they turned out to have only 128 mb only. i tried these memory sticks on my intel celeron cpu and p3 cpu. both of them show the same results.

the info from the seller for the memory is: 168Pin-Pc133 SDRAM NonECC 256M 32X64

could anyone tell me what happened? originally i just thought that the memory either works fine (256 mb), or it doesn't work if the board does not support. but this situation about turning 256 mb rams into 128 mb is reallyl confusing.

this is the second time about the same problem. the first time i guessed that the seller miss-labeled the memory. but now i think there must be something else going wrong....

thanks for your help.

first off, does the mobo that your testing these DIMM's support
256MB DIMM's, if you don't know go to crucial.com, there you can
lookup your mobo to see if it even supports those DIMM's.

i tried two mother boards: one is MS 6161. And the other is ASUS P3B.

i tested my old 256mb ram, which is double sided, on both computers and it worked fine. but these new memory sticks cannot work.

any further suggestion?

thanks!!

well I'm thinking something funny might be going on too.
one of two things, either there defective or mislabeled.

It could be that the mobo doesn't support the dimms density? Does the new 256M memory have the same number of chips on the dimm as your other 256 dimm? Sometimes if the chip density is too high then it will only see half the amount of memory. This happened to me with 128M & 64M memory but has not ever happened with any of the 256M sticks that I have bought
