I recently purchased 2 8gb memory sticks for my Lenovo p400 Ideapad Touch. The specs are below:
When I install the RAM, the computer only reads 8gb. Even when I go into the msconfig file, it shows 8 gb and all 8gb is available for use. I have also removed the RAM sticks and switched spots to make sure one of the sticks was not defective. I had also downloaded the most recent system update software to check any driver/bios updates. None were found. I'm confused to why it's only seeing 8 gb? Is there a setting in the bios I need to change for the timing? Is there a setting in the BIOS I missed? Thanks in advance for any assistance.

Hi nawnek ,
Welcome to the Community Forums.
Would 8 GB also show in the BIOS?
RAM : DDR3-1600/1333MHz SODIMM × 2 (max 16 GB)
Try using one ram per slot at a time to help isolate if one of the memory slot is having an issue.
Using the original ram , try to add the new one , swapping each new ram to the same slot.
Recommended OEM ram here on item 12 page 95.
Update us how it goes.

Hi nawnek ,
Would each ram work on each slot?
Would using the original ram + new ram work in both slots alternately showing summed up total ram?
It is the same difference I noticed but would expect DDRL (low voltage 1.35v) to be able to backwardly compatible to systemboards for DDR3 1.5v.
OEM certified RAM are listed on item 12 page 95.
Using the part number, you may check on lenovo encompass for pricing and availability.
11200345 DDR3 1600 8GB, HynixHMT41GS6MFR8C-PB or 11200342 DDR3 1600 8GB, Samsung, M471B1G73BH0-CK0 would work just fine .

I updated the BIOS. I thought the Lenovo software update would update the BIOS but that was my mistake. I shouldn't have assumed since it was still the old BIOS. Then I swapped out the 4gb sticks that came stock to make sure both memory slots were working. Since they were, I swapped out the 8gb stick into each slot and they were working. I put in the 8gb sticks and both were finally recognized. Not sure if it was the BIOS update or just reseating the memory sticks but it works now. Thanks.
p.s. I did previously reseat the memory sticks multiple times before coming onto the forums. Maybe I was doing somethign wrong before? Or maybe it was the glass of wine I had before, during and after the initial installation...

Hi nawnek ,
Thanks for confirming the GSKILL Ripjaw Series Model F3-1600C9D-16GRSL kit works on the model.
DDR3L does confirms backward compatibility with less volt and therefore less heat for your system.
Loose contact does happen and it maybe BIOS reset or having systemboard re organize detection of new device.
Nonetheless all is fix now and for sure you would enjoy the RAM upgrade you have now.
