Question

I recnetly purchased Lenovo G575 4383-43U from Best Buy and thinking about upgrading RAM.

 

On the best buy site (http://www.bestbuy.com/site/Lenovo+-+Laptop+/+AMD+E-Series+Processor+/+15.6%26%2334%3B+Display+/+2GB...), it says expandable to 4GB, but when I look at the data sheet for G575, it says it can take up to 8GB.

 

http://shop.lenovo.com/us/ww/pdf/G575_Datasheet_US.pdf

 

The data sheet seems to be the one for E-350 though. 

 

Answer

 

The G575 series of system contains a variety of sub models, some of which contain 2 DIMM sockets and some which contain only one socket.  Each socket can support a 1GB, 2GB, or 4GB module.  Models with a single socket can be upgraded to 4GB of memory while those with 2 sockets can support up to 8GB.

 

Common models of type 4383 with a single socket are -42U and -43U

 

8GB modules have not been tested by Lenovo and may or may not work.  A 64 bit version of the OS is required to access more than 4GB of memory regardless of the physical amount installed.
