This article covers PC3L-12800 16GB ノートPC用メモリ DDR3L 1600MHz 8GB×2枚 SODIMM CL11 204Pin Non-ECC 電圧1.35V ＆ 1.5V 両対応 (× 2).

Overview

The Rasalas PC3L-12800 16GB (8GB×2) kit is a DDR3L SODIMM memory upgrade designed for legacy laptops. Operating at 1600MHz with CAS latency CL11, it supports both 1.35V and 1.5V voltages, making it compatible with a wide range of older notebooks. The kit consists of two 8GB modules in a 204-pin SODIMM form factor, Non-ECC and unbuffered.
This memory is aimed at users who want to breathe new life into pre-2014 laptops—machines from the Core 2 Duo or early Core i era. By upgrading from 4GB or 8GB to 16GB, everyday tasks like web browsing, office work, and light multitasking become noticeably smoother. However, compatibility is not universal: certain chipsets (HM55, GM45, PM45, QM57) may not recognize a single 8GB stick, so checking your motherboard's chipset is essential.
Priced around ¥11,600 on online retailers, it sits in the mid-range for DDR3L kits. Warranty is typically 30 days from the seller. It's a niche product for those who refuse to retire their old laptops just yet.

Compatibility Guide

  • Memory Standard: DDR3L (1.35V) and DDR3 (1.5V) dual voltage support. Avoid using 1.5V in a 1.35V-only slot to prevent damage.
  • Form Factor: 204-pin SODIMM – fits standard laptop memory slots.
  • Supported Chipsets: Intel HM55, GM45, PM45, QM57, and other DDR3-era chipsets. Note: these chipsets may not support 8GB per slot; if so, use 4GB×2 instead.
  • Unsupported Environments: Laptops manufactured after 2014 (DDR4 or later) are not compatible. Also, some MacBook models may have issues.
  • Installation Tips: Gently rub the gold contacts with a pencil eraser to remove oxidation. Insert the module at a 60-degree angle, then press down until it clicks into place.

Product Info

The Rasalas PC3L-12800 16GB kit is an entry-to-mid-range memory upgrade for legacy laptops. It was released around 2023 and is sold primarily through Japanese online retailers. Its market position is “legacy PC life-extension” – it won't compete with modern DDR4/DDR5 in bandwidth, but it's a practical choice for keeping older machines usable.
Key specifications:

  • Memory Type: DDR3L
  • Capacity: 16GB (2×8GB)
  • Speed: 1600 MHz (PC3L-12800)
  • CAS Latency: CL11
  • Voltage: 1.35V / 1.5V dual
  • Pin Count: 204-pin SODIMM
  • ECC: No (Non-ECC)
  • Warranty: Seller-dependent (typically 30 days)

Best Use Cases

  • Reviving an old laptop for basic tasks: If you have a pre-2014 notebook (e.g., ThinkPad T400, Dell Latitude E6400, HP ProBook 4530s) that feels sluggish, upgrading from 4GB to 16GB can make a huge difference for web browsing, email, and Office applications. The dual-channel configuration (2×8GB) doubles memory bandwidth compared to a single stick.
  • Budget-conscious upgrade: New DDR3L kits are becoming scarce and expensive on the second-hand market. At ¥11,600, this kit offers a reasonable price-to-performance ratio for those who want a fresh, warrantied product.
  • Users with dual-voltage compatible machines: If your laptop supports both 1.35V and 1.5V, this kit works in either mode. However, be mindful of heat when running at 1.5V in a 1.35V-optimized system.
  • Not for: Post-2014 laptops (DDR4 or newer) – it won't fit. Also, if you need high memory bandwidth for gaming or video editing, DDR3L's 1600MHz will be a bottleneck; consider upgrading to a modern platform instead.

Things to Consider

  • Chipset limitation: HM55, GM45, PM45, and QM57 chipsets may not recognize 8GB modules. Verify your chipset before purchase. If unsure, opt for 4GB×2 sticks.
  • Voltage caution: Using 1.5V in a 1.35V-only slot can damage the memory controller. Check your laptop's voltage requirement in the manual or BIOS.
  • Performance ceiling: DDR3L 1600MHz offers about one-third the bandwidth of modern DDR5-4800. It's fine for everyday use but not for memory-intensive workloads like virtual machines or large databases.
  • Competitor comparison: Crucial and Kingston offer similar kits with better brand reputation and longer warranties, but at a higher price. Rasalas is a lesser-known brand; online retailers reviews are mixed but generally positive. If long-term reliability is critical, consider a major brand.

FAQ

Q: Can I use this memory in a MacBook Pro (Mid 2012)?
A: The MacBook Pro Mid 2012 supports DDR3L 1600MHz SODIMM, but compatibility with third-party memory can vary. Check your specific model and search for user reports. Some Macs may not recognize 16GB (2×8GB) configurations. It's safer to buy from a vendor that explicitly lists Mac compatibility.
Q: Can I buy just one 8GB stick instead of the kit?
A: This product is sold as a 2×8GB kit only. If you need a single 8GB module, look for a separate single-stick listing from Rasalas or another brand.
Q: Will this work in a desktop PC?
A: No. This is a 204-pin SODIMM designed for laptops. Desktop motherboards use 288-pin DIMM slots. You need DDR3L DIMM modules for desktop use.
