installed 8 mb ram only reads 2.93 mb
I have an HP G62 notebook PC with Windows 7 premium 64-bit. It came with 4 GB memory. I added 4 GB more, but it still only reads 2.93 GB. I can't figure out why it won't read the additional memory.

Yes, when I pull up the properties, it says I have a 64-but CPU. When the additional 4GB is removed, it's the same thing. It was that way before I added the 4GB too - never changed.
In Properties, you should see System Type: 64-bit operating system, x64-based processor.
Do you see the words above exactly as I showed?
Did the HP G62 computer come with Windows 7 64-bit? or did you install it yourself?

It only says 64-bit operating system, but nothing else, not x64-based processor. I says Intel Pentium CPU P6100 @ 2.00 Ghz
Windows came pre-installed on the computer.

It would seem not to be a 64-bit CPU. Either that or the memory socket (motherboard) is faulty.
I would contact HP support with you exact model number.

OK - So which one is required to be 64-bit to access the additional memory - OS or CPU?
Have you tried both SODIMM sticks one at a time in the first slot? One stick might be nonfunctional.
Your laptop depending on the actual model, should be able to handle 8GB. The OS should be able to handle it. I have seen bad sticks of RAM do this in desktops and once you replace both the problem might disappear.
What speed RAM are both chips?
Do you have another set of 8GB to try from known good machine?

It might be timing issue of added RAM. What are the part #'s of both SODIMM sticks?
Some chipsets have a maximum RAM limit of 4GB. Does the RAM show up fully from within the BIOS? According to the link below, your PC only supports a max of 4GB, but sometimes their info isn't correct. Maybe you should check directly with HP whether more than 4GB is supported in that model:

The CPU can support up to 8GB. Most G62 model support up to 8GB, but not all. We do need to know the exact model.
ASKER
They are each 4GB RAM. I don't know the part numbers offhand. I'd have to open the laptop to find out. Don't have any other memory sticks to try. I'd have to buy some.

The exact model is HP G62-358NR
That model does support 8GB.

OK. Thank you very much!!
Does the computer have a 64-bit CPU? I wouldn't think 64-bit Windows would install if it could not run.
What happens if you remove the additional 4GB? And please verify the bit strength in Properties.
