Max memory in Sony Vaio PCG-Z505R[X] ?
I've got an old PCG-Z505RX with 128M RAM, which is 64M on motherboard
and 64M SODIMM. The instructions say it can take 192M max by swapping out the extra 64M SODIMM for a 128M SODIMM. Does anyone know if I could put a 256M SODIMM in it and get even more memory? I'm wondering if the instructions simply predate 256M SODIMMs, or if there's a limit in the Vaio itself, either the chipset or the motherboard, which would prevent a 256M SODIMM either working or providing its full capacity to the laptop? -- Andrew Gabriel |

This is quite common in the desktop machines from 5 or 6 years ago. You could install a single sided 256mb sdram stick and the machine would only see 128mb but if you got a double sided 256 stick it would see all of it. Have you taken the machine apart to see if the onboard 64mb is not replaceable? Typically it's just another sodimm that is hidden from view. Obviously the only way to know for sure is try it, or hopefully someone here may have already done that and will answer. |
