Newegg.com Ram

[Airesz]

I am currently upgrading and Compaq Presario 5003US.

System Spec

Windows Xp Machine
933 MHz CPU
256MB ram
(1 PC100 Stick from Compaq)
(1 PC133 Stick from Crucial Memory)
On Board Video

Upgrading to
2 – PC133 256Mb SDRAM
1 - Sapphire 256 PCI Video Card

I bought 2 SDRAM sticks from newegg.com that I was told would be compatible with my computer. I really didn’t think anymore about my purchase until it arrived today. I install the new hardware in the compaq and once done I tried to boot the computer, it wouldn’t power on. I quickly found that the memory I was told would be compatible with my computer was defiantly not.

At this point it was no big deal. I have other computers here that the memory would be compatible with.

I went to my other computer and replaced the memory and all was well…..

Later this evening I was looking at my system properties information and I became confused. My computer was only showing 256MB of RAM installed when it should have been showing 512MB of RAM

My Issue:
I looked at my packing list from newegg.com and it showed that I paid for 2 – 256 PC133 SDRAM.

I looked on the ram it self and the sticker showed 256Mb PC133
I looked at the packing that the ram came in it says AC133x64/256/8c

But what I don’t understand is why my computer would only show the RAM at 128MB per stick. I have tested the RAM in two computers and each with the same result.

Anyway I am not sure if I am doing something wrong or if they made a BIG mistake and sent me the wrong memory. I do plan to call newegg.com this morning but I would like to know what you all think.

Other Info:
The numbers on the sticker are:
AVE6432U40A3133AVA
12210014787101205HB this number is below the bar code

The number in the Ram SI6006ILLDTK the 1 may = I

maybe one of the RAM sticks is dead?

It may be high density ram and you are trying to use it in a motherboard that needs low density. This will cause only half of it to be recognized. Your part number is for a 256mb module. If the ram was cheap, I guarantee you it's high density. If you can post the models of the other computers and/or motherboards , I can see what they require - and please give us a Newegg link to what you bought.
