This article covers キングストン Kingston デスクトップPC用メモリ DDR4 2666MHz 16GBx1枚 HyperX FURY CL16 HX426C16FB3.

Overview

Kingston's HyperX brand brings us the FURY series HX426C16FB3/16, a single 16GB DDR4-2666MHz memory module. With a CAS latency of CL16 and a low operating voltage of 1.2V, this stick emphasizes stability and power efficiency over aggressive overclocking. It's a no-frills choice for budget-conscious builders who want reliable DDR4 performance. Although it lacks XMP 2.0 profiles, the module supports Plug N Play at 2400MHz and 2666MHz, meaning it will run at its rated speed automatically on compatible motherboards. For those willing to tweak, the HyperX Fury series can be manually overclocked up to 3600MHz, though this requires careful BIOS adjustment. Positioned as an entry-to-mid-range DDR4 upgrade, the HX426C16FB3/16 is ideal for extending the life of a DDR4 system or building a cost-effective workstation. Its single-stick format allows gradual expansion, and the lifetime warranty adds long-term peace of mind.

Compatibility Guide

This memory uses the standard DDR4 UDIMM (Unbuffered DIMM) form factor, fitting any desktop motherboard with DDR4 slots. Compatible platforms include Intel 100-series chipsets and later, as well as AMD AM4, TR4, and sTRX4 (Threadripper) sockets. Dual-channel: Requires two sticks of identical modules. You can buy one now and add the same model later for dual-channel. Motherboard QVL: Always check the memory QVL list of your motherboard to confirm compatibility, especially for manual overclocking targets. * Voltage: Operates at 1.2V JEDEC, so no extra voltage adjustments are needed for default operation.

Product Info

Released around 2019, the HX426C16FB3/16 remains widely available through major retailers. Its price fluctuates around ¥2,500–¥3,000 per stick. Kingston backs it with a lifetime warranty and free technical support. Market positioning: Entry-level to mid-range DDR4. It prioritizes stability and affordability over high-frequency performance. Capacity: 16GB (1 stick) Speed: DDR4-2666MHz CL16-18-18-38? (actual timings may vary, but CL16 is primary) Voltage: 1.2V (JEDEC) Form Factor: UDIMM * Warranty: Lifetime

Best Use Cases

  1. Budget PC Builders If you're assembling a low-cost office PC or a media server, this single 16GB stick provides ample memory for multitasking and web browsing. You can later add a second stick for 32GB without wasting money. Not ideal for high-FPS gaming where dual-channel bandwidth matters. 2. Office and Productivity Upgrades Upgrading an older DDR4 system from 8GB to 24GB by adding a 16GB stick alongside an existing 8GB stick? Possibly, but mismatched capacities may force single-channel mode. For best results, replace both sticks with a matched pair. This stick is excellent for homogeneous upgrades. 3. Emergency Spare Part Having a spare DDR4 module on hand can be a lifesaver for troubleshooting or temporary system builds. The lifetime warranty makes it a safe long-term investment. Who should NOT buy this: Gamers who need 3200MHz+ speeds for Ryzen or Intel performance. Users who want RGB lighting or low-profile heatsinks for small cases. ## Alternatives
    Direct competitors include Crucial CT16G4DFD8266 (DDR4-2666 CL19) and Teamgroup TED416G2666C19 (CL19). Crucial: Micron-based, slightly cheaper but CL19 latency is higher. HyperX has lower CL16 and lifetime warranty vs Crucial's limited lifetime. Teamgroup: Often priced lower, but CL19 and 5-year warranty. HyperX offers better latency and permanent warranty. For a modest premium, the HyperX delivers better responsiveness and longer support, making it the stronger choice for longevity-focused builds.

Things to Consider

Remember that this module does not support XMP 2.0 profiles, so any overclocking beyond 2666MHz must be done manually via BIOS settings. Beginners may find this challenging. Also, a single 16GB stick will run in single-channel mode, which reduces memory bandwidth by roughly half compared to dual-channel. For CPU-intensive tasks like video editing or gaming, dual-channel is strongly recommended. Finally, DDR4 is becoming legacy; if you're building a new system from scratch, DDR5 platforms offer better future-proofing. However, for extending the life of an existing DDR4 system, this module is a reliable and affordable choice. ## FAQ Q: Does this memory support Intel XMP? A: No, it does not have XMP 2.0 profiles. However, it runs at 2666MHz automatically via Plug N Play on compatible motherboards. Manual overclocking is possible. Q: Can I use two sticks for dual-channel? A: Yes, buy two of the same model (HX426C16FB3/16) and install them in the correct slots (usually A2/B2) for dual-channel operation. Q: What is the warranty period? A: Kingston offers a lifetime warranty. No registration is required; contact support for RMA if needed.
