No, DDR and DDR2 are different types of memory. DDR2 supports higher speeds and has different socket. Check your laptop manufactore website to find out which type of memory your laptop works with.
depending on the laptop, it could be DDR, DDR2 or DDR3. But the form factor is all the same. Its all SO-DIMM memory
no.
A DDR2 memory stick cannot be installed correctly in a DDR slot.
Kingston memory modules will work on any laptop, provided it's of the same memory type (DDR, DDR2, &tc.).
Yes. DDR2 memory has double the transfer rate of DDR memory.
Information on ddr laptop memory can be found from sveral different sources for purchase and information. A helpfull website is: http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=4151&name=DDR%20-%20Laptop%20Memory.
DDR laptop memory stands for Double Data Rate. The DDR means how fast your laptop can load data from your hard drive to your memory. This website explains things better: http://www.laptop-rentals.us/ddr-laptop-memory.htm
DDR and DDR2
No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
AnswerNo. DDR3 is not backward compatible with DDR2 and DDR. e.g. DDR3 has 1.5V power, DDR2 needs 1.8V and DDR needs 2.5V power. In terms of standard motherboard slots also the notch or the key for different memory modules is at different place for the three type of memory thus preventing any accidental insertion in memory slots which can damage the memory and or the motherboard. More Information:Gateway Tech Support said their Gateway MD7820u Notebook is compatible with both.SODIMM DDR3 might have the same pins as SODIMM DDR2.
If you insert a DDR2 memory card into a slot that usually holds a DDR memory card, the card will not be recognized by the system and a message will appear stating that there is an error with the memory card. Please do not insert memory cards into non-matching slots, you may damage the system. If your system does not become damaged as a result of poor memory card reading, your DDR2 card will simply only act as a DDR card and not make full use of the DDR2 capabilities.
I believe so but it'll downgrade to the lowest one.
