VGN-CR11Z/R Maximum Ram

[chromium]

My G/F has a the model listed above in Candy Red and it came with 2gb of Ram and Vista installed.
I installed Windows 7 64bit on the system but would like to upgrade the Ram to 4gb. I've seen people selling 2nd hand models with 4gb installed, yet the information I get around the internet claims that the maximum system memory is 2gb?

Can I get a bios upgrade to allow 4gb? I'm competent with PC's and really want to swap the 1gb modules out for 2x2gb but this conflicting information is making me have doubts.

P.S: The unit seems to have two different names? It's listed as both the CR11z/r and PCG-5J1M??

Thanks in advance.

Hi chromium and welcome.

Sony's Specifications for the VGN-CR11Z/R confirm that it supports 4GB.

The correct mode name is VGN-CR11Z/R.  The other model is a chassis number shared by several models and you will not find it used on any Sony website.
