August of 2013, a friend at church gave me this Compaq Presario 2004 desktop computer. He and his wife have moved to Minnesota and I have lost contact so cannot ask them. It only came with 256 Mb and the other slot is empty. A friend in Austrailia (I am in Atlanta, Georgia USA); also has an XP computer desktop but not the same brand. He shipped me 2 x 1 Gig and 2 x 2 Gig memory cards this past Wednesday. Will take 10-12 days to get to me. Do the memory cards have to be specific for my computer or will others work? Can I only put just 256 Mb more in the other slot? I am 64 (almost 65) and have never been inside a computer tower. A friend in my building will put the memory in for me. I am confused on how much Mb is 1 Gig and how much is 2? Here is the scan results for my computer: Crucial USA - scan results
I am sorry for the issues that you have experienced with your upgrade. What is the make and model of the computer that you were installing the memory in? What is the full part number on the memory module themselves? They should read CT25664AA800.16F,etc. Thank you in advance for this information.
I'm an IT engineer and subscribred to this feed.
In looking up RAM for new laptops I occasionally find model numbers off by a digit or letter.
Many times these minor differences are owing to different HD or SSD, Optical drive, touchscreen, etc.
My question is; if model numbers are not an exact match, can this also mean the RAM is not upgradeable?
Thanks for your message.
So I can look in to this part further can you provide some more information for me? On the module each black DRAM chip will have the manufacturer printed on it in small writing, can you confirm what that says?
The sticker on the memory module will also show the batch number of the memory module. The batch number is generally listed as something like BL111f5.7k.
If you can provide the above information then I can certainly look into this for you.
