Re: Lenovo G40-70/80GA - Ram Upgrade Issue

2015-11-29, 17:44 PM

The current RAM and your new RAM should match each other identically.  From the service manual it indicates several different DDR3L 8gb sticks are on the approved list and I would chose from them if possible, purchasing a matched pair.  IE...  Two SK HMT41GS6BFR8A-PB/RD 8GB DDR3L 1600 sticks (Samsung) to provide 16gb of total memory.

 

The reason behind this is differing memory manufactures (assemblers) use various producers to supply their chips to use on the sticks.  This can cause issues when you are attempting to use memory from different sources (Kingston, Cruial, Hynix etc) in a desktop or notebook computer.  Not only are the timings going to be different, the arrangement (Rows, dual or single sided, etc) will be different as well.

 

I have never supported "mix and match" memory for notebook computers as they are very picky about what will and will not work.

 

Cheers.

I would reccomend downloading your maintenence manual and reading thru the CPU upgrade section.  Also - look into the parts list for CPU that you can use for the update.  Some notebooks do not have an upgrade for the CPU as the socket is not removable.

 

Good luck.

Re: Lenovo G40-70/80GA - Ram Upgrade Issue

I have the same desire to upgrade RAM in my G40-30 (from 2 Gb till 8 Gb for example).

So please let me know about performance of new one.

According to specifications table in Hardware Maintenance Manual it should be the next:

RAM: DDR3L, 1066MT/s,1333MT/s

 

Otherwise in parts list I can see another characteristics:

RAM, M471B1G73QH0-YK0 35nmQ 8GB DDR3L 1600

RAM, Hyn HMT41GS6AFR8A-PB DDR3L 1600 8GB

RAM, RMT3160ME68FAF-1600 8GB DDR3L 1600

RAM, Mic MT16KTF1G64HZ-1G6E1 DDR3L 1600 8GB

RAM, M471B1G73DB0-YK0 25nm 8GB DDR3L 1600

RAM, SK HMT41GS6BFR8A-PB/RD 8GB DDR3L 1600

 

So which friequency 1333 MT/s or 1600 MT/s should be choosen? Or it doesn't matter?
