I am having hard time figuring out the right RAM module for HP Pavilion dv6t-1300 CTO Notebook PC. A similar issue was discussed in another topic. And according to the service manual which is located at
http://h10032.www1.hp.com/ctg/Manual/c01859609 (this is also the service manual suggested in the other topic for this model)
the RAM is DDR2. However when I googled ram upgrade for that specific model it is claimed that the compatible memory module is DDR3. Besides, I have DDR3 installed in dv6t-1300 CTO and it works like a charm.. Can someone help me clear my confusion please!!
Thanks in advance.

From what I can tell, the service manual linked to the support page is only for those notebooks with amd processors and chipsets.
Yours has an Intel processor and with a CTO model there are no specs listed.
I found an Intel based dv6-1300 model below and it lists DDR3 memory is specified.
If you have DDR3 memory in your PC now, then that is what you need to use.
DDR2 memory runs at a higher voltage and the memory slot is cut in a different place than in a DDR3 chip, making it impossible to install a DDR2 memory chip in a slot meant for DD3, and visa versa.
Do make sure you get memory that is DDR3 and not DDR3L and it cannot exceed PC3-10600.
Also make sure you get memory with 8 little black chips on each side of the board, not 4.
If you live in the USA you want to get this memory for your notebook (2 x 4 GB).

is PC3-12800 not backwards compatible with PC3-10600 and PC3-8500? How did you determine the speed, by the way?
Do you happen to know a really good technical document or weblink (other than wikpedia) that gives all the different memory types and their details such as compatibility etc?
By the way, here is another document from HP and my laptop's CPU is listed there as well (Intel Core2 Duo T6600) and the memory module is PC2-6400, 800-MHz, DDR2
Thank you for your time.

Most of the forum posts I have read indicate that PC3-12800 is not backward compatible all the way back to PC3-8500. It normally only goes back to PC3-10600.
See this discussion for the difficulties that arise with DDR3 memory and older model HP notebooks.
Here's the problem with your model...
Some models with the Mobile Intel Series chipsets take DDR2 memory and some take DDR3.
So you have to make absolutely sure that your notebook is either runing DDR2 or DDR3 memory and the only way you can do that is to physically check the memory module label.
You can also run the free crucial system scanner and see what it reports.
I do not know of any other links that describe the differences between memory types. I usually refer to the wikipedia article myself.

Do the latency timings matter?
Sometimes, I see DDR3 memory modules for Apple Macbook on eBay. Would they work on a non-Apple notebook PC without any issues? I guess.. They have a different Voltage, don't they?
