This article covers キングストン Kingston デスクトップ PCメモリ DDR2-667(PC2-5300) 1GB Non-ECC CL5 DIMM 240pin KVR667D2N5.

Overview

Kingston's KVR667D2N5/1G is a 1GB DDR2-667 (PC2-5300) memory module designed for desktop computers. It uses a 240-pin DIMM form factor, operates at CL5 latency, and is non-ECC, unbuffered. This module is squarely aimed at legacy systems—motherboards from the late 2000s to early 2010s that rely on DDR2 RAM. While it's utterly obsolete for modern builds, it remains a practical solution for keeping older PCs running, repairing vintage machines, or building a retro gaming rig on a budget.

Compatibility Guide

This memory is exclusively compatible with motherboards that have DDR2 DIMM slots (240-pin, 1.8V). It will not physically fit into DDR3 or DDR4 slots, and the electrical interface is completely different. Before purchasing, check your motherboard's memory support list (QVL) to confirm compatibility with DDR2-667 modules. If you're running a dual-channel setup, you'll need two identical modules (same capacity, speed, and timings). Be aware that some older chipsets may only support DDR2-533 or DDR2-800, so performance may vary.

Product Info

The KVR667D2N5/1G is part of Kingston's ValueRAM series, positioned as an entry-level, reliable memory solution for OEM and upgrade use. It has been on the market for many years but remains available through online retailers like typically priced around ¥4,000 per stick. Kingston backs it with a limited lifetime warranty, though terms and conditions apply. In today's market, this product is strictly a replacement or expansion part for legacy DDR2 systems—it has no place in any modern PC build.

Best Use Cases

  • Legacy PC Upgrades: If you're still using a Core 2 Duo or early Core i-series desktop with DDR2 memory, adding a 1GB stick can breathe some life into the machine for light office work, web browsing, or media playback. It's a cheap way to delay a full platform upgrade, but don't expect miracles.
  • Retro Gaming Rigs: Enthusiasts building a dedicated Windows XP or Windows 7 gaming PC will find this DDR2 module a cost-effective choice. It pairs well with older graphics cards and CPUs, allowing you to run classic titles smoothly. However, it won't handle memory-hungry modern games even in that environment.
  • Repair and Refurbishment: For technicians or hobbyists fixing up old computers, this module is a reliable drop-in replacement for faulty or missing RAM. The Kingston brand and lifetime warranty add peace of mind over generic unbranded sticks.

Things to Consider

First and foremost, this is DDR2 memory—it is incompatible with any modern DDR3/DDR4/DDR5 system. Verify your motherboard's memory type before buying. Secondly, 1GB is extremely limited by today's standards; even a lightweight operating system will struggle with heavy multitasking. If your motherboard supports larger sticks (e.g., 2GB per slot), seek those out instead. Third, while the price per stick is low, buying multiple sticks to reach a usable capacity may not be cost-effective compared to moving to a newer platform. Finally, warranty coverage may not apply to secondhand purchases, so buy from a reputable seller.

FAQ

  • Q: Can I use this memory in a DDR3 motherboard?
    A: No. DDR2 and DDR3 modules have different key notches and pin counts, making physical insertion impossible. Forcing it will damage both the RAM and the motherboard.
  • Q: Will two of these modules work in dual-channel mode?
    A: Yes, if your motherboard supports dual-channel DDR2, a pair of identical KVR667D2N5/1G sticks will run in dual-channel, improving memory bandwidth.
  • Q: Is the lifetime warranty still valid if I buy this from a third-party seller on online retailers?
    A: Kingston's warranty applies to products purchased from authorized retailers. If the online retailers seller is not an authorized reseller, the warranty may be void. Check the product listing or contact Kingston directly to confirm.
  • Q: How much faster is DDR2-667 compared to DDR2-533?
    A: DDR2-667 offers a theoretical bandwidth of 5.3 GB/s, about 25% more than DDR2-533's 4.3 GB/s. In real-world use, the difference is noticeable in memory-intensive tasks but not dramatic for basic computing.
