Operating System: Microsoft Windows 10 (32-bit)

Hello,

I was wondering if I can mix/match a 4GB DDR3L ram stick with a 4GB DDR3 stick.  I wasn't able to get the computer to boot with the DDR3 in any configuration, even solo.  Is this not a compatible format for 840 G1?  Or is the ram stick DOA 😞

 

 

Edit:

 

Original RAM 1x

SKhynix - 4GB 2Rx8 PC3L-1200S-11-12-F3

 

Trying to upgrade with 1x

Kingston - 4GB 2Rx8 PC3-1200S-11-11-F3

 

 

Thanks!
