HP Recommended
Product: HP EliteBook 8440P
Operating System: Microsoft Windows 7 (64-bit)

Hi again everyone. I've scoured these forums and others, and can't find a definitive answer to upgrading my RAM memory. 

 

My system:

HP EliteBook 8440P

2.8 GHz Intel Core i7 M640

Win7 Professional 64bit

Bus clock 133 MHz

Bios: HP 68ccu, ver. F.11 (2010) 

Dual core, hyper threaded (4)

(?) Mobile Intel QM57 chipset

 

According to Belarc Advisor I currently have one 4MB module of Samsung RAM under the keyboard. The second slot is empty.  First off, isn't most RAM memory sold in GB? I know the computer is capable of 8GB, and the Kingston modules I just tried to install were 4GB each.  The Kingston sticks are 8GB (2x4), PC3-10600, CL9, 204 Pin SODIMM, 1.5V modules, and they do NOT work on this laptop even though they should.

 

Has anyone found the secret to exactly which memory modules will work with this specific laptop model? Is it density issues? Voltage issues? Am I missing a driver. Do I need to sing to the thing while I install the memory?

 

Seriously, any help at all will be appreciated.
