FAQ
What Sony notebook models is this memory module compatible with?
This Axiom VGP-MM512I-AX module is designed for specific Sony VAIO notebook models including the VGN-S series (such as VGN-S150, VGN-S170, VGN-S270), VGN-T series (including VGN-T150P/L, VGN-T250, VGN-T350), and related variants. The compatibility list includes dozens of specific model numbers that share the same memory interface and physical form factor requirements. Always verify your exact model number against the provided compatibility list before purchase.
What is the difference between DDR-333 and PC-2664 memory standards?
DDR-333 and PC-2664 refer to the same memory technology but use different naming conventions. DDR-333 indicates the memory's effective data rate of 333 million transfers per second. PC-2664 describes the module's theoretical peak bandwidth of 2664 MB/s (megabytes per second), calculated as 333 MHz × 8 bytes (64-bit data path) × 2 for double data rate. Both terms correctly identify this module's performance characteristics, with PC-2664 being the JEDEC standard designation and DDR-333 being the more common consumer-facing name.
Can this memory module be used in desktop computers or other notebook brands?
No, this module is specifically designed for Sony VAIO notebooks that use the 172-pin Micro-DIMM form factor. Desktop computers typically use 184-pin or 240-pin DIMMs with different physical dimensions and electrical characteristics. Other notebook brands generally utilize different pin configurations, form factors, or voltage requirements. Attempting to install this module in incompatible systems may cause damage to the memory or motherboard and will void the warranty.
What performance improvement can I expect from upgrading to this 512MB module?
Upgrading to this 512MB DDR-333 module can provide noticeable performance improvements in memory-constrained systems. Benefits typically include reduced swapping to virtual memory on disk, faster application loading times, smoother multitasking between several open programs, and improved responsiveness in memory-intensive tasks. The exact improvement depends on your specific usage patterns and how much your current applications exceed your existing RAM capacity. Systems originally configured with 256MB or less will see the most dramatic improvements.
What does the 'Micro-DIMM' form factor mean for installation?
Micro-DIMM (Dual In-line Memory Module) refers to a physically smaller memory module designed specifically for compact notebook computers. This 172-pin Micro-DIMM is approximately half the size of standard notebook SO-DIMMs and requires precise alignment during installation. The compact design allows Sony engineers to maximize internal space utilization in their portable systems. Installation typically involves accessing the notebook's memory compartment, aligning the module's notch with the slot key, inserting at a slight angle, then pressing down until retention clips engage automatically.
What does the lifetime limited warranty cover for this memory module?
Axiom provides a lifetime limited warranty that covers defects in materials and workmanship for the duration of the product's life. This warranty typically includes replacement or repair of modules that fail under normal use conditions. The warranty is limited to the original purchaser and requires proof of purchase. It does not cover damage resulting from improper installation, physical abuse, electrical surges, or use in incompatible systems. For warranty service, you would need to contact Axiom Memory Solutions directly with your purchase documentation and the manufacturer part number VGP-MM512I-AX.
