This article covers KLEVV DDR4 32GB (1x32GB) 3200MHz CL22 1.2V SODIMM ノートパソコン RAM メモリ SK Hynixチップ(KD4BGSA80-32N220A).

Overview

The KLEVV DDR4 32GB (1x32GB) 3200MHz CL22 1.2V SODIMM (model KD4BGSA80-32N220A) is a single-stick 32GB memory module designed for laptop upgrades. It uses genuine SK Hynix DRAM chips and operates at JEDEC-standard 1.2V with a CAS latency of CL22. The module runs at 3200MHz (PC4-25600) and supports XMP 2.0 for one-step overclocking on compatible platforms.
This product targets users who need large memory capacity for demanding tasks like video editing, virtual machines, or simply extending the life of an older laptop. It sits in the entry-to-mid-range segment of DDR4 SODIMMs, offering a balance of capacity, stability, and price. The limited lifetime warranty adds peace of mind for long-term use.

Compatibility Guide

The KLEVV KD4BGSA80-32N220A is a 260-pin DDR4 SO-DIMM module, compatible with laptops, Mini PCs, and some compact desktops that accept DDR4 SODIMMs. It works with Intel platforms from 400-series chipsets onward (Skylake through Comet Lake and later) and AMD AM4/TR4 platforms including Ryzen 3/5/7/9 and Threadripper processors.
Important: Not all laptops support 32GB per slot. Older models (pre-2018) may have a 16GB per slot limit. Always check your laptop's maximum memory capacity and supported memory type (DDR4 vs DDR5) before purchasing. The module is JEDEC-compliant, so it should run at 3200MHz on most systems without manual configuration.

Product Info

The KLEVV DDR4 32GB SODIMM features SK Hynix original chips, JEDEC-standard 1.2V operation, and timings of 22-22-51. It supports XMP 2.0 for easy overclocking on compatible motherboards. The module is available through Japanese online retailers, with a limited lifetime warranty.
Market positioning: entry to mid-range. It prioritizes capacity and stability over extreme low latency, making it ideal for users who need large memory without breaking the bank.

Best Use Cases

  • Creative professionals on laptops: Video editors, 3D artists, and photographers working with large files will benefit from 32GB capacity. The SK Hynix chips ensure reliable operation during long rendering sessions. However, if you need the lowest latency for competitive gaming, consider CL16 modules instead.
  • Developers running VMs and containers: Running multiple virtual machines or Docker containers simultaneously demands significant RAM. This module provides ample headroom. For memory-bandwidth-sensitive workloads, dual-channel configuration is recommended.
  • Users extending the life of an older laptop: Upgrading from 8GB to 32GB can dramatically improve multitasking and overall responsiveness. But if the CPU or storage is the bottleneck, the upgrade may not yield proportional gains.
  • Budget-conscious users needing high capacity: This single 32GB stick offers good value per gigabyte. However, if your laptop supports dual-channel, two 16GB sticks will provide better memory bandwidth.

Things to Consider

The CL22 latency is relatively loose compared to gaming-oriented modules (CL16-18). For pure gaming performance, especially with integrated graphics, lower latency modules may offer better frame rates. Additionally, running a single 32GB stick in single-channel mode halves memory bandwidth compared to dual-channel. If your laptop has two SODIMM slots, consider buying two sticks for optimal performance.
Compatibility caveat: Some older chipsets or BIOS versions may not recognize a 32GB SODIMM. Always verify your laptop's maximum supported memory per slot before purchasing. Also, this module is DDR4, not DDR5 — ensure your system uses DDR4.

FAQ

Q: Can I use this memory in a laptop with Intel Core i7-12700H?
A: Yes, if your laptop has DDR4 SODIMM slots. Many 12th-gen Intel laptops use DDR4, but some high-end models use DDR5. Check your laptop's specifications.
Q: Will I see a performance boost if I buy two sticks for dual-channel?
A: Yes, especially for integrated graphics and memory-bound tasks. Dual-channel can improve gaming FPS by 10-20% and significantly speed up data-intensive applications.
Q: Is this memory compatible with AMD Ryzen 7 5800H?
A: Yes, Ryzen 5000 series supports DDR4 SODIMM at 3200MHz. Ensure your BIOS is updated for best compatibility.
