RAM memory in Elitebook 8560w

[camelotshadow]

Very informative thread. Sorry to chime in so late but I had a question & was hoping for a update.

It seems the memory configuration is if I read the article correctly is:

slot 1 primary with slot 1 (secondary)

slot 2 primary with slot2 (secondary )

Do you have to fill both slots 1's before adding memory to slot 2's?

If the laptop comes with 4 GB then HP will install it under the keyboard?

If the laptop come with 8 GB then HP will install 4GB under the keyboard & 4 GB on the  expansion slot 1 under bottom?

If the laptop came with 8GB then it seems to say the next addition to memory should be under the keyboard???

Has anyone tried to add memory to the bottom without filling the primary slot 2 under the keyboard? Will it work?

I'm not going to mess with installing any memory under the keyboard & I was hoping I could fill both slots under the bottom & have them work with only one under the keyboard...

Someone said they were going to try it.

Does anyone know if this will work before I buy a used 8560W.

If it won't work I'd like to know as basically if it comes with 8 GB I can only get the laptop of to 12 GB by switching the 4 under the bottom to a 8.  I won't be able to add more memory until that 2nd slot under the keyboard is filled.

I might as well buy a laptop w 16 GB already installed.

I hope my question is clear.

Thanks

On these computers, in both the expansion memory slots (on the bottom of the

computer) and the primary memory slots (under the keyboard), slot 1 must be populated before slot 2

is populated."

This is really unclear!

I went back & read the maintenace pdf & it doesn't seem to say that a 3rd slot filled has to be the primary.

It says that slot one on a primary or slot one on an expansion has to be filled before adding memory to the 2nd slot.

It doesn't even seem to say that you can't add memory under the keyboard & leave the expansion slots unfilled.

I was hoping this was the case as I'd ratherleave the botton slots available for upgraded emmory as the keyboard ones are hard to acess.

Has anyone tried to just add memory to just the primary slots or filled the expanions slots while leaving one primary slot empty?

This really is very unclear? Does anyone know?

Thanks

I was reading this thread to understand these memory issues as well and here,s what i got

A 8560w with win pro 7-64 bit software  by HP and I5 core quad processors  BUT BUT BUT

  There is only two 204 pin mem slots at bottom of laptop  and nothing under key board NOTHING not even recepticle sockets are there.   So i have  64 bit system with only a two dimm memory system.  This build was verified by HP support. So this means max 16 GB of ram only and this generally refers onlt to 32 bit system yet this is a quad code 64 bit system.

 I got a lemon.

So it could be understood that 2 4,s = 8 gb  divided by 4 core = 2gb per processor  or 2 8gb simms = 16gb 0r 4gb per proc.

I also found out that there are two types of simms 204 that work in 8560w  1333mz and 1600mz ddr3  12800/10600
