Pages 75 & 76 of the Sony Vaio PCV RX406 User Guide ( as per Sony Web Site and available
here ) states :
Use only PC2100 DDR SDRAM modules ( 266 Mhz ).
Your PC supports a maximum of 1.5Gb memory and has 3 x 184 pin slots to accept the memory modules.
A single Kingston 512Mb module will cost around £32.00 with UK delivery - e.g. from
here but shop around as prices vary considerably.
Graphics :
According to the specifications for your PC on the Sony Web Site
here you have an nVidia GeForce4 MX 460 with 64 Mb DDR memory.
Can anyone advise on a suitable upgrade ?
