Overview

The Sony KSY-GRX500/256 is a 256MB DDR SDRAM memory module in a 200-pin SO-DIMM form factor, sourced from Kingston and designed for the Sony VAIO PCG-GRX500 Series of laptops. For owners of these legacy machines, finding compatible DDR1 memory can be a challenge as the technology has long been superseded by newer standards. This module addresses that need by providing a tested, compatible upgrade path that can help improve multitasking and application responsiveness on the GRX500 platform.

While 256MB is minimal by today's standards, adding this module to a VAIO PCG-GRX500 that is running at or near its original memory configuration can provide a noticeable improvement when running period-appropriate software and operating systems such as Windows XP. The 200-pin SO-DIMM design ensures correct physical and electrical compatibility with the laptop's memory slot. This module is best suited for users maintaining, restoring, or extending the life of their existing VAIO hardware rather than those seeking modern performance levels.
