Re: Ideapad Z570 RAM Upgrade

Hi Jay86 , 


Welcome to the Community Forums. 


Max RAM supported in a 32 bit OS:  In non-PAE modes of x86 processors, the RAM is always limited to 3.76GB , staying in 32 bit max ram usable is 4 GB . 


"In computing, the 3 GB barrier is a limitation of some 32-bit operating systems running on x86 microprocessors. It prevents the operating systems from using more than about 3 GB (3 × 10243 bytes) of main memory (RAM). The exact barrier varies by motherboard and I/O device configuration, particularly the size of video RAM; it may be in the range of 2.75 GB to 3.5 GB.[2] The barrier is not present with a 64-bit processor and 64-bit operating system "


As per product specification :

8GB max7; PC3-10600 1333MHz DDR3, non-parity,
dual-channel capable, two 204-pin SO-DIMM sockets 


If you changed from 32 bit to 64 bit architecture then you can push for an 8 GB max ram for your model as others claim that 16 GB would also be possible.


Hope this help answer your query.
