i have a quick question today, Actually i have a Hp Elitebook 8440p with core i5 and 2gb ram ( samsung 2rx8 pc3-10600).
and i am running windows 7 x64 bit.
so i decided to upgrade memory to 8GB and i install 2x4GB (matched pair) (hynix 1rx8 pc3-10600). but it does not work. wont start up and goes in loop. and if i put original samsung 2GB back in then its work fine..
i tried many times with all possible combinations but it does not work. and if i go to bios setup, it shows 8GB memory installed in it but cant get thorugh in it.
i am wondering is it the problem of 2rx8 and 1rx8? because my original old got 2rx8 and new ones got 1rx8 on it...
i am really worried about it...please help me soon...Thanks in advance

Yes, I believe you have installed high density memory, and your notebook won't work with that.
You notebook needs low density memory with the following specs...
- Module Size: 4GB
- Package: 204-pin SODIMM
- Feature: DDR3 PC3-10600
- Specs: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.35V or 1.5V • 512Meg x 64 •
I recommend this memory for your notebook...
or...2 of these.

I cannot say for 100% sure, but yes, I think the number of memory chips on the board can indicate density.
The symptoms you have described indicate a density issue to a "T."
The memory shows up fine in the BIOS, but the PC refuses to work with it.
I have suggested this cause to several others and when they purchased the lower density memory with 16 chips on the board, their problem was solved.

Looks to be good to me, but I am not sure about the speed (PC-12800).
Not sure if it is backward compatible to PC-8500.
The PC-10600 memory is, but I am not sure about 12800.
See if you can test it out before you commit to buying it.
