Last Modified: 2013-11-17
I have an Asus G50v, I looked up ram and it said I shouldn't put modules over 2 gb in any slot. So can I have a max of 4 gb ram? Is there anyway to bypass this? I'd like to install 4gb in one or both slots. thanks.

The specs state the maximum amount of ram the system can have is 4gb.
This is a limitation with the hardware. It won't recognise ram greater than 4gb. So if you put in two 4gb modules, the system would probably still work, but will only detect 4gb during POST.

This is before you even get to the OS so loading a 64bit OS (which is needed for ram greater than 4gb) wouldn't help.

The only way to bypass this limitation that I know of would be to modify the hardware which would require electrical enginerring skills.

Sorry, it looks like 4 gigs is the limit on this rig. And only with 2 x 2gig modules.

My findings are different and it seems that your notebook can un-officially support 8GB (in total). But, in doing so, you may risk to lose the warranty as the official document says that it only supports 4GB (in total).

From my google search, Asus G50v shall run Windows Vista 64 bit and its specification is as follows:-

"Processor : Intel Core 2 Duo T9400 2.53GHz

If the above information is correct, the motherboard your notebook has:-

North bridge : Intel PM45 Express

From the Intel website, it says:-

Besides, BIOS can restrict the maximum size of the memory module to be installed.

Please go into the BIOS of your notebook and post the information of the brand of the BIOS and its version back.

The information below may also be useful for you.
According to the comment of Fabian, it says:-
"The bios from asus has to be able to remap memory usage.  Asus is infamous for not having this in the bios be default as is the problem in G1Sn.  It has been put into bios 300 of the G1S.

You must first determine if you bios has the capability built in before you install 8gb.

"The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature." "

Have a look inside the BIOS setup to see whether there is such feature mentioned above.

You could try upgrading the BIOS to version 300.

I would search the forums to ensure there are no issues with the upgrade on your model as if you don't get the right version for your hardware the laptop won't boot.

For a working laptop, BIOS upgrade is too risky. You may turn your laptop into a brick if you get any problem during the BIOS upgrade.

There is no "safe" BIOS upgrade? Is there anything else that can be done?

YES, there is "safe" BIOS upgrade. i.e. to use only the latest BIOS according to the model of your notebook.

From the link below, the latest version of BIOS for G50v is 0213.
