Crucial 32GB DDR5-6400 CL52 CUDIMM Single Module 288-pin Desktop Memory On-Die ECC 1.1V — CUDIMM DDR5-6400 for Core Ultra 200S

One 32GB clocked DDR5-6400 module with an on-board clock driver for stable high speed.

The Crucial 32GB DDR5-6400 CUDIMM (part CT32G64C52CU5) is a single 288-pin clocked unbuffered module that hits 6400 MT/s at CL52 and 1.1V. Its on-module Client Clock Driver (CKD) regenerates the clock signal for stable plug-and-play DDR5-6400 on Intel Core Ultra 200S platforms, with on-die ECC for reliability. Typically in stock with fast delivery across Cyprus.

Best For

✓Intel Core Ultra 200S (Arrow Lake) desktop builds
✓Users wanting plug-and-play DDR5-6400 without tuning
✓High-refresh gaming and content creation
✓Latency-tolerant, bandwidth-hungry workloads
✓Single-stick upgrades with room to expand
✓Enthusiast Intel 800-series motherboards

Key Features

 
On-board CKD for DDR5-6400
The Client Clock Driver regenerates the base clock on the module, sustaining stable 6400 MT/s without manual overclocking on supported boards.
 
Plug-and-play on Core Ultra 200S
On Intel Core Ultra 200S platforms it runs at rated 6400 MT/s automatically, no XMP tuning required.
 
UDIMM bypass compatibility
On non-CUDIMM boards it operates in bypass mode as a standard UDIMM (CKD disabled), typically around DDR5-5600.
 
On-die ECC at 1.1V
Built-in on-die ECC corrects single-bit errors inside the DRAM at an efficient 1.1V; this is not server module ECC.

Frequently Asked Questions

What is a CUDIMM and do I need one?
A CUDIMM (clocked unbuffered DIMM) adds an on-module clock driver so DDR5 can run at very high speeds reliably. To get the full 6400 MT/s you need a CUDIMM-capable board such as Intel Core Ultra 200S (800-series).
Will it work on my current board?
Yes, in bypass mode. On non-CUDIMM or AMD boards it runs as a standard UDIMM with the clock driver disabled, typically at around DDR5-5600 rather than 6400.
Is this a single module or a kit?
It is a single 32GB CUDIMM. For matched dual-channel, choose the 2x32GB kit CT2K32G64C52CU5 or add a second identical module.
Does it have ECC?
It uses DDR5 on-die ECC for internal error correction. This is not server/sideband ECC, so it works in standard consumer desktops.
Singular Expert Insight
CUDIMMs are the path to stable high-speed DDR5 on Intel Core Ultra 200S: the on-module clock driver lets this stick run 6400 MT/s plug-and-play. On older or AMD boards it still works, but drops to standard UDIMM bypass speeds, so it is best paired with a CUDIMM-capable Intel 800-series board. For a matched pair, step up to the CT2K32G64C52CU5 64GB kit.

Buyer's Guide

Buy it if

You have an Intel Core Ultra 200S board and want plug-and-play DDR5-6400 with an on-board clock driver.

Skip it if

Your board is not CUDIMM-capable and you specifically need 6400, or you run AMD where a standard kit fits better.

Also consider

The 2x32GB kit CT2K32G64C52CU5 for dual-channel, or a standard DDR5-5600/6000 kit for non-CUDIMM boards.
