Hi Guys,

 

I have to upgrade the RAMs of the machines at work and could do with some advice. Here are some information on the machines:

 

A. One Lenovo G50-80 80E5 laptop - to be upgraded to 8GB 
(currently has 4GB of RAM, the maximum RAM the machine can be upgraded to is 16GB.)
 
B. Two Acer Aspire AX3950 desktops - to be upgraded to 8GB
(currently has 2GB of RAM, the maximum RAM this machine can take is 8GB.)
 

Kindly also note that the RAMs in all machines have never been previously upgraded. This will be the first time.

 

 

My questions are as follows:

 

1. Are RAMs for desktops and laptops all built the same? Or are RAMs for desktops of bigger sizes than those for laptops? This is because I have been told by Acer than the RAM model for my desktop is DDR3 1333 MHz DIMM, and when I searched an online store, I found this RAM model for Notebooks (please refer here). Does it matter whether it is DDR3 1333MHz DIMM or DDR3 1333MHz Sodimm?

 

2. Does anyone know how many memory slots are there in the Lenovo G50-80 80E5 laptop? And the RAM model for this laptop?

 

Appreciate any guidance I can get.

 

Thank you very much.

 

 

Regards,
Andrew

Hi,
 

1. Are RAMs for desktops and laptops all built the same? Or are RAMs for desktops of bigger sizes than those for laptops? This is because I have been told by Acer than the RAM model for my desktop is DDR3 1333 MHz DIMM, and when I searched an online store, I found this RAM model for Notebooks (please refer here). Does it matter whether it is DDR3 1333MHz DIMM or DDR3 1333MHz Sodimm?

 

Sodimm - memory for Laptops

Dimm - memory for Desktops

 

They are physically different doesn't fit on the slots.
 

2. Does anyone know how many memory slots are there in the Lenovo G50-80 80E5 laptop? And the RAM model for this laptop?

 

2 slots. I suggest you open the machine to get the specs of the 4GB dimm currently installed and purchase one with the same specs. Unless you can't find on the market the same specs using a faster one (if supported) will not add nothing because is the lower one that limits the speed used to access the memory.

 

Most likely the installed 4GB are PC3L-12800 1600Mhz DDR3L SDRAM SO-DIMM 204-pin

I think this is the specs page for the laptop, I believe there are two slots for memory, DDR3-SO-DIMM specifically.  As for the desktops, I think those use DDR3-1333 SDRAM.  Some all-in-one PC's use SO-DIMM but most desktop PC's use normal SDRAM.

Thanks Guys.

 

One more question: does it matter what brand I use? My laptop is currently installed with a Samsung RAM, if I add another brand's RAM of the same specs, would that pose any compatibility issues for the laptop?

Usually the same specs should work, but it's impossible to be 100% sure.
