Repair or maintain your old Sony VAIO PCV E Series Desktop Computer with new memory from Memory America. The VAIO PCV E Series computers can take a maximum of 256 MB of RAM. Most models in the E series have 2 memory slots, holding 128 MB of RAM in each. The computers use SDRAM, an older style of memory. Because the memory is an older style and won’t work in newer computers, the RAM is very affordable.
