Sony Vaio VGN TX770P Memory PCG 4G1L Memory
Maximum Memory: 2.5gb
Base Memory: 512mb (Non removable)
Upgrade Sockets: 1 (1 bank of 1)
Even though Sony states maximum memory is 1.5 gb with the use of a 1gb module. We have tested on site for numerous customers a 2gb module which works flawlessly. The reason is Sony had not tested a 2gb module as they were not available when this notebook system was released and nobody went back to upgrade their system manuals. So here you go, enjoy the extra benefits and order the 2gb module for your system if you are looking for additional power and speed. Your maximum memory would be then 2.5gb
