This article covers キングストン Kingston デスクトップPC用メモリ DDR4 2666MHz 4GBx2枚 HyperX FURY CL16 HX426C16FB3K2.

Overview

The Kingston HyperX FURY DDR4-2666MHz 4GB×2 kit (model HX426C16FB3K2/8) is a dual-channel memory set aimed at budget-conscious builders. Running at 2666 MT/s with CAS latency 16 and 1.2V JEDEC voltage, it prioritizes stability over aggressive overclocking. The absence of XMP profiles means it works out-of-the-box on virtually any DDR4 motherboard. Each module features a low-profile black heat spreader that looks clean in any build. With a total capacity of 8GB, this kit is suitable for light productivity, office work, web browsing, and entry-level gaming where memory demand is modest. Positioned as an entry-level DDR4 solution, this kit remains relevant for users who already own a DDR4 platform and want a reliable, no-fuss memory upgrade without breaking the bank. The lifetime warranty adds significant peace of mind.

Compatibility Guide

Form factor: Standard 288-pin DIMM (UDIMM) for desktop PCs. Compatible with all DDR4 motherboards including Mini-ITX, microATX, and ATX. Memory standard: DDR4-2666 CL16-18-18 @1.2V, JEDEC compliant. No XMP support; runs at base speed automatically. Platform support: Works with Intel 100-series through 600-series chipsets (excluding LGA1851) and AMD AM4 / TR4 / sTRX4 platforms. Avoid using with DDR5-only boards. Note: 8GB total capacity may limit multitasking. If your workload includes multiple browser tabs, office suites and light photo editing, you may want to consider a 16GB kit instead.

Product Info

Release: Approx. 2019 as part of the HyperX FURY lineup. Price: Around ¥21,145 on Japan at the time of writing (subject to market fluctuation). Warranty: Lifetime (free technical support and replacement for defects). Market tier: Entry-level. This is a basic JEDEC-speed kit with no overclocking features. It’s best for budget builds or extending the life of an older DDR4 system in 2026.

Best Use Cases

Budget office PC / home server: If you’re building a system for email, spreadsheets, or a file server, 8GB is sufficient. This kit is affordable and reliable. However, do not use it for heavy virtualization or video editing. Secondary / retro gaming PC: For playing older games (pre-2020) or using a secondary machine for LAN parties, 8GB is acceptable. Modern AAA titles at 1080p often require 16GB or more. * Temporary or emergency replacement: If your existing memory fails and you need a quick, cheap drop-in replacement, this kit is widely available and guaranteed to work without tweaking. Who should NOT buy: Users who plan to play modern games, run virtual machines, edit 4K video, or perform heavy multitasking. Also avoid if your CPU/motherboard officially supports DDR4-3200 or higher and you want to maximize performance. ## Alternatives
Crucial DDR4-2666 8GB (2×4GB) CT2K4G4DFS8266: Very similar specs, also JEDEC-only. Slightly cheaper in some regions, but lacks a heat spreader. TeamGroup Elite DDR4-2666 8GB (2×4GB) TED48G2666C19: Lower price point with looser timings (CL19). Acceptable for extreme budget builds. Kingston ValueRAM KVR26N19S8L/8 (single 8GB): If you want a single stick to leave an upgrade slot open, ValueRAM is the stripped-down option. But you lose dual-channel benefits. Our pick: The HyperX FURY kit wins for its combination of heat spreader aesthetics, lifetime warranty, and guaranteed JEDEC stability.

Things to Consider

Capacity constraints: 8GB is below the recommended minimum for any current OS if you multitask. Windows 11 alone uses 2-4GB; add a browser and you’re at 6-7GB. Expect performance hiccups under load. Speed limitations: DDR4-2666 is now a legacy speed. If you build a new system with a Ryzen 7000 or Intel 13th-gen CPU, you’d be better off with DDR5. This kit is only suited for existing DDR4 builds. * Upgrade path: With two modules populated, adding more requires matching modules—hard to find later. Consider starting with 16GB (2×8GB) for greater future flexibility. ## FAQ Q: Does this memory support XMP? A: No, it operates at JEDEC standard DDR4-2666 CL16-18-18@1.2V. Plug and play; no BIOS settings required. Q: Can I use this with a Ryzen 7 5800X? A: Yes, the 5800X supports DDR4-3200 but will run this at 2666 MHz. You will lose some performance in CPU-bound tasks. For gaming, consider at least DDR4-3200 CL16. Q: Is the lifetime warranty transferable? A: Kingston’s warranty covers the original purchaser, but they generally honor it regardless of proof of purchase as long as the module is genuine. Always register if possible.
