This unbuffered, non-ECC DDR2 UDIMM is a desktop memory module optimized for legacy LGA 775 or Socket AM2 platforms, where it delivers reliable performance for productivity and light gaming workloads. Its dual-rank x8 organization combined with a CL5 column access strobe latency ensures efficient data throughput and low signal latency without the overhead of error correction.
1. Unbuffered UDIMM design eliminates the register latency found in server memory, delivering the straight-through signal path that desktop processors crave for snappier application launches and lower input lag.
2. DDR2 technology operates at a lower voltage than its predecessors, reducing heat buildup inside the tower and helping your air-cooled rig maintain stable temperatures during marathon gaming sessions.
3. Dual Rank x8 organization interleaves data across two internal ranks, keeping the memory pipeline full so your desktop flies through demanding multitasking without playback stuttering when you jump between browser tabs and creative suites.
4. CL5 latency delivers tight command-to-data turnaround, giving content creators smoother timeline scrubbing and faster effects previews in video editing workloads on period-appropriate platforms.
5. The 667MHz clock speed sustains ample bandwidth for early multi-core desktop CPUs, preventing memory bottlenecks that would otherwise choke frame delivery in classic gaming titles or degrade system feel under heavy OS loads.
Determined by its 240-pin UDIMM form factor and unbuffered, non-ECC architecture, the MT16HTF25664AZ-667H1 is unequivocally a desktop memory module built for responsive mainstream computing. Its four defining characteristics translate directly into tangible performance where it matters most.
First, the unbuffered, non-ECC signal design eliminates the latency penalty of registered or error-correcting buffer chips. For a gamer pushing through a 3A title like Cyberpunk 2077 or a video editor scrubbing a 4K timeline in Premiere Pro, this means every CPU memory request is served with minimal delay, keeping frame times tight and preview windows buttery smooth. Second, the DDR2-667 speed paired with a CAS latency of just 5 cycles delivers a balanced blend of bandwidth and quick first-word access. When batch-processing hundreds of RAW photos, that low latency directly reduces the idle time your processor spends waiting for data. Third, the dual-rank x8 organization interleaves memory banks across two internal ranks, allowing the memory controller to issue commands to one rank while the other finishes a cycle, effectively boosting sustained throughput during heavy multitasking between a render and a live streaming session. Finally, the standard 240-pin UDIMM footprint and RoHS compliance guarantee a straightforward, drop-in upgrade on a vast ecosystem of desktop motherboards, letting you revitalize an aging system into a capable workhorse without complex configuration.
Gaming Build
For a responsive gaming experience, deploy two identical 2 GB modules in dual-channel configuration to double memory bandwidth. While total 4 GB is minimal by modern standards, pairing two of these DDR2-667 modules reduces stutter in older titles and light esports. Serious modern gaming rigs should move to 16 GB or 32 GB kits, but this module can temporarily fuel a budget legacy build.
Content Creation
Content creation workloads—video editing, 3D rendering—thrive on massive capacity and multi-channel throughput. Using four of these 2 GB UDIMMs (if the motherboard supports four slots) yields 8 GB, which can handle basic 1080p timeline editing on a legacy platform. For real productivity, upgrade to 64 GB across higher-density DDR3/DDR4 kits; these 2 GB sticks only serve as a transitional step.
General Productivity
In an office or multitasking environment, a single 2 GB module keeps cost minimal for web browsing, email, and document editing on older systems. Adding a second identical stick to reach dual-channel 4 GB offers a noticeable smoothness boost for spreadsheets and multiple browser tabs, hitting a sweet spot between price and everyday performance.
This DDR2 desktop memory, rigorously tested, is compatible with Dell OptiPlex 745, HP dc7800, and Lenovo M57.
Q: Can I mix this MT16HTF25664AZ-667H1 with other memory modules of different brands or speeds?
A: Mixing is possible but not recommended. The system will downclock all modules to the slowest speed and may use relaxed timings, potentially causing instability. For best results, install matched kits.
Q: Is this memory compatible with my desktop system?
A: It is a standard 240-pin DDR2-667 UDIMM. Please verify your motherboard supports 2GB dual-rank modules at 667MHz and uses non-ECC unbuffered memory. Most Intel 965/975 or AMD 690G chipsets are compatible.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel operation, install identical modules in like-colored slots (e.g., slots 0 & 2). With a single module, any slot works, but consult your board manual for the preferred first slot.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-standard DDR2-667 CL5 module without XMP (not available for DDR2). It is rated for stable operation at 667MHz and does not guarantee headroom beyond standard specifications.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. It is built to strict JEDEC and RoHS standards, resulting in an AFR well below industry average when operated within rated voltage and temperature conditions.
