G550 - Maximum RAM capacity

Hi

 

How much RAM can I install in my G550 laptop ?

 

Model: g550 (model name: 20023)

chipset: gl40

 

Now I've got 3 GB (DDR3 PC3-8500). According to  Personal Systems Reference Lenovo Essential Notebooks
2006 to present - withdrawn, 4 GB is maximum capacity for my model but I'm not sure what does it mean. 

 

Doest it mean I can install 4 GB RAM  for each slot ? Or 4GB RAM is the maximum amount of memory that my matherboard can deal with ?

It means 2-2gb sticks total.  1   2 gb stick in each slot.

 

It looks like you already have 1-2gb stick in there, so you would just have to replace the 1-1gb stick with a 2gb stick.

Thanks for help.

 

So my laptop can operate with only 4 GB RAM. I thought  I would be able to put in it 2 x 4 GB Smiley Happy What a pity Smiley Sad

Re: G550 - Maximum RAM capacity

Usually, manufacturers specs call for a certain maximum of memory, but the machines are able to take a lot more.

 

In all the searches that I did concerning your machine, they all came up with a 4gb total.  

 

You could run Crucial's scanner and that would tell you exactly how much ram your machine will take.

 

Keep in mind that a 32bit OS will only see about 3.4 gb of ram.  To see any more would require a 64bit OS.

Max Ram on a G550 Laptop

Everything I find "officially" says this computer can only have 4GB ram.

However I think that is only because it uses a 32bit operating system and that is all that it can see.

I would like to know if I install a 64bit operating system on it like Linux Mint 64bit can I take the Ram up to 8GB?

Does anyone know this?

Thanks

Dan

Re: Max Ram on a G550 Laptop

I have installed (2) 4GB pieces of memory in the G550.

It is only showing me 4GB.

Is this a MotherBoard Limitation?

Is there a Bios update that might work?

Thanks

Re: Max Ram on a G550 Laptop

From Lenovos' Overview page for G550:

 

"DDR3, 800/1066MHz support, 2x SODIMM, up to 8 GB Max"

 

Is all memory visible in the BIOS?  (Press F2 key at boot)

 

And yes, you will need 64 bit OS to use extra 4 GB.

Re: Max Ram on a G550 Laptop

Has anyone managed to install 8GB yet? I'm getting mixed messages here, so it'd be great to know for sure.

Re: Max Ram on a G550 Laptop

I can confirm that 8GB of 1066mhz DDR3 Ram works in the lenovo G550 laptop.  I have wanted to upgrade my Ram for a long time, even though having an SSD makes the need for 8GB irrelevant a bit.  Never the less I was able to get some ram very cheap and tried it out.  it shows up in the bios as well as in windows.  I have included a picture below in my dropbox:

This link won't be up forever but i can defintely confirm that 8gb is supported!  Good luck!
