G6 2123-US Memory Upgrade

[FuriousGeorge71]

Good morning.  A friend asked me to upgrade the memory in her HP Pavilion G62123-US laptop which has 4 GB.  I ordered the same exact memory chip that is currently in the top memory slot.  The memory currently installed in top memory bank is 4GB PC3-12800 DDR3 1600MHz MT16KTF51264 HZ-1G6M1.  I ordered the same exact memory stick and installed in bottom memory bank.  Laptop boots fine but still only recognizes 4GB.  I replaced new memory into top memory bank alone and machine boots fine and says 4GB.  If I put either sticks into bottom memory bank, laptop won't boot.

There is only one DIMM bank listed when I  use the HP assistant boot program and the memory tests are good.  I cannot look at all the information in the BIOs as it is grayed out and setting an Administrator password does not allow access to any settings for some reason.  Would I have to enable the bottom or second memory bank in BIOS to have it recognize the adiitonal ram or maybe the bottom memory bank is bad?  How would I gain access to the BIOS settings to see the memory setup?

Any and all help is greatly appreciated!

Hi:

You would not have to enable the memory slot.

It most likely is no good.

Thank you for the response as I was hoping that wasnt' the case.  Probably a long shot, but could I place an 8GB memory chip in the working memory bank to replace the 4 GB?  I understood they needed to be paired allow 8GB but could be wrong.

Thanks again in advance.

You're very welcome.

Since that model has an AMD processor, I do not believe each slot would support 8 GB of memory.

If it had an Intel 3rd gen core processor like many of the g6-2xxx notebooks do, there would have been a chance of an 8 GB memory module working in one slot.

If you have an 8 GB DDR3(L)-1600 memory chip you can experiment with, you can give it a try.

It wouldn't wreck anything.   Worst case scenario would be the PC would not boot up.

Buying one to try would not be recommended, because the odds of it working are stacked against you.

I won't take the chance of purchasing an 8GB and let my friend know she's stuck with the 4GB.  On the plus side, I was able to replace her broken keyboard at least.

Thanks!

Anytime.

Glad to have been of assistance.
