2 different ddr2 ram cards not the same? I’m not trying to mix different cards. I know the issues that can come out of that. What my question is I have 2 gigs (2 1gb) in my desktop now. And is not enough. A friend gave me a card to me (1 4gb). He told me when he gave it to me that it was a ddr3 and that made sense because when I took it home and tried to plug it in, it wouldn’t fit. But…
After doing a little research on the ram card, everywhere says its a ddr2. ?? As far as I could find out the notch is so you cant mix ddr, ddr2, ddr3 in a uncompilable MB. But is there ddr2 ram chips that are different than other ddr2 chips??
It is racking my brain and I cant stop wanting to know the answer.
I’m new to the site 🙂 Thanks for any help I can get.
Here are the specs of the card in question:
Samsung 4gb 2Rx4 PC2-5300-555-11-EO M395T5160QZ4-CE68 0841
If there is any other information that you need, let me know. Again, the cards that are in my PC now, say on the label DDR2, the Samsung just says the above information.
All DDR2 is notched the same.***NOTE: that comment was not accurate. See OtheHill’s response about Fully Buffered DDR2***http://albamedia.net/wp-content/upl…

And Laptop RAM is MUCH shorter than desktop RAM.

You mentioned that the RAM may have come from a server. If that’s the case, it’s probably ECC RAM. It’s notched exactly the same as non-ECC DDR2, but it may not work in a standard desktop machine. Also, being that it’s a 4GB stick, you’d have to confirm that your board accepts sticks that large. However, you should not mix ECC & non-ECC. One other thing to be aware of – ECC RAM is slower than non-ECC.
