0B47381 8GB DDR3L-1600 SODIMM delivered reliable performance and efficient power consumption.
Strong laptop memory upgrade for business environments.
Consistent multitasking capability after installation.
Smooth compatibility with ThinkPad models.
Stable and energy-efficient DDR3L module.
Dependable high-capacity notebook memory.
Excellent responsiveness boost for productivity workloads.
This module offers 8GB capacity, DDR3L technology at 1.35V, PC3-12800 (1600MHz) data rate, 204-pin SODIMM form factor, and non-ECC unbuffered architecture.
It is compatible with Lenovo notebooks and workstations that accept 204-pin DDR3L-1600MHz SODIMMs, including ThinkPad T, X, L series and certain IdeaPad models—please verify your service manual.
Yes. You can mix it with another DDR3L-1600MHz SODIMM of equal or different size, but for optimal performance use matched pairs in dual-channel mode.
Yes. Operating at 1.35V instead of 1.5V lowers power draw by up to 10%, extending battery life in portable systems.
Yes. Increasing RAM capacity reduces paging and enables smoother multitasking, faster application load times, and improved responsiveness.
This module is non-ECC unbuffered memory designed for consumer and professional laptops without error-correcting requirements.
Yes. When installed in a matched pair with another identical DDR3L-1600MHz SODIMM, it enables dual-channel mode for up to 25% higher bandwidth.
Power off and unplug your laptop, remove the back panel, align the gold contacts at a 45° angle, insert the module until it clicks, then secure the panel and reboot.
No manual BIOS adjustment is required; most systems automatically detect DDR3L-1600MHz modules and configure timings and voltage.
Maximum supported memory depends on your motherboard, but most Lenovo laptops with two SODIMM slots support up to 16GB (2×8GB) or 32GB (4×8GB) on select workstations.
Check your BIOS memory information screen or use a system utility (like CPU-Z) to confirm the module’s size, voltage, and operating frequency.
PC3-12800 runs at 1600MHz with 12.8GB/s peak bandwidth, while PC3-10600 runs at 1333MHz with 10.6GB/s bandwidth—offering lower performance and throughput.
No. Desktop motherboards use 240-pin DIMM slots; this SODIMM is designed exclusively for laptops and compatible small-form-factor systems.
Yes. Increasing RAM capacity and bandwidth reduces load times and enhances frame rates in games and responsiveness in video/photo editing software.
It runs at a low voltage of 1.35V, which reduces heat output and power consumption compared to standard 1.5V DDR3 modules.
You can buy authorized Lenovo memory upgrades from Lenovo’s official store, certified resellers, or select online retailers to ensure authenticity and warranty coverage.
