Where to Find Memory Block Suppliers?
China remains the central hub for memory block (memory module) manufacturing, with Shenzhen emerging as the dominant production and distribution center. The city's strategic concentration of electronics component suppliers, semiconductor distributors, and logistics networks enables rapid prototyping, scalable assembly, and efficient global shipping. Over 70% of the active suppliers operate from this region, leveraging integrated supply chains that reduce material procurement lead times by up to 40% compared to non-specialized markets.
The ecosystem supports both high-volume OEM/ODM production and low-MOQ sampling, making it ideal for B2B buyers across IT hardware, server integration, and consumer electronics sectors. Key advantages include access to DDR3, DDR4, and DDR5-grade components; in-house testing facilities; and modular customization for form factor, speed, and thermal management. Average production lead times range from 15–25 days, with air freight delivery to major global ports within 5–7 business days.
How to Choose Memory Block Suppliers?
Effective supplier selection requires a structured evaluation across technical, operational, and transactional criteria:
Quality Assurance & Compliance
Verify adherence to JEDEC standards for DDR memory specifications. While formal ISO 9001 certification is not explicitly stated in available data, prioritize suppliers demonstrating consistent on-time delivery (>98%) and low defect rates through verifiable reorder metrics. For EU and North American markets, confirm RoHS compliance and compatibility with environmental directives.
Production and Technical Capability
Assess supplier infrastructure based on product range and operational scale:
- Suppliers listing 100+ RAM SKUs indicate mature inventory and sourcing channels (e.g., Shenzhen Eon Technology Co., Ltd. with 106 RAM listings)
- Dedicated focus on memory modules—over general IT hardware—suggests deeper technical expertise
- Customization options such as RGB heatsinks, branded labels, and capacity tuning reflect advanced post-production capabilities
- Cross-reference response time (<3 hours preferred) and reorder rate (>30% indicates customer satisfaction) as proxies for service reliability
Procurement Terms and Risk Mitigation
Evaluate order flexibility and financial safeguards:
- Minimum Order Quantities (MOQs) vary widely—from 1 piece (prototyping-friendly) to 50 pieces—enabling tiered procurement strategies
- Price dispersion (e.g., $4–$330 per unit) reflects differences in grade (new vs. used), capacity (4GB–64GB), and application (desktop, laptop, server)
- Use platform-based transaction protection where available, requiring inspection before final payment release
- Request sample units to validate performance, thermal stability, and labeling accuracy prior to bulk orders
What Are the Best Memory Block Suppliers?
| Company Name | Main Products (Listings) | Online Revenue | On-Time Delivery | Reorder Rate | Avg. Response Time | Customization | Min. Order |
|---|---|---|---|---|---|---|---|
| SHENZHEN LONG TERM INTERNATIONAL LIMITED | RAMs, DDR4/DDR3, RGB Heatsink Options | US $390,000+ | 100% | 33% | ≤2h | Yes (color, label, logo, heatsink) | 2–10 pieces |
| Shenzhen Eon Technology Co., Ltd. | RAMs (106), HDDs (340), CPUs | US $1,700,000+ | 98% | 19% | ≤4h | No | 1–2 pieces |
| Shenzhen Juhor Precision Technology Co., Ltd. | RAMs (244), HDDs (68) | US $10,000+ | 78% | <15% | ≤5h | No | 1 piece |
| Shenzhen Miaoqianyu Electronic Trading Center | RAMs (255), HDDs (759), Network Cards | US $130,000+ | 100% | 60% | ≤3h | No | 10 pieces |

Performance Analysis
SHENZHEN LONG TERM INTERNATIONAL LIMITED stands out for responsiveness (≤2h) and perfect on-time delivery, complemented by strong customization capabilities—ideal for branded or specialized memory solutions. Shenzhen Miaoqianyu demonstrates exceptional customer retention (60% reorder rate), indicating high satisfaction despite higher MOQs. Shenzhen Eon Technology leads in revenue volume and product diversity, suggesting robust backend operations, though its lower reorder rate warrants closer scrutiny of post-sale support. Suppliers like Shenzhen Juhor offer single-unit ordering but lag in delivery consistency (78%), posing fulfillment risks for time-sensitive contracts. Buyers prioritizing flexibility should consider companies supporting 1-piece MOQs and DDR5-ready products, while large-scale integrators benefit from partners with proven volume throughput and heatsink or labeling services.
FAQs
How to verify memory block supplier reliability?
Analyze on-time delivery performance (target ≥98%), reorder rates (≥30% indicates repeat business), and response speed (≤4h). Request product specifications, including voltage (1.2V for DDR4), frequency (2400MHz–5200MHz), and ECC/non-ECC designation. Confirm whether modules are new, refurbished, or used through clear documentation.
What is the typical sampling timeline?
Standard samples ship within 3–7 days after confirmation. Allow an additional 5–10 days for international delivery via express courier. Complex customizations (e.g., RGB lighting, OEM packaging) may extend lead time to 14–20 days.
Can suppliers produce DDR5 and server-grade memory modules?
Yes. Several suppliers list DDR5-5200 modules and server-grade 32GB/64GB ECC DIMMs (e.g., M393A8G40CB4), confirming capability in next-generation and enterprise segments. Validate compatibility with motherboard chipsets before procurement.
Do suppliers offer private labeling or OEM packaging?
Yes. SHENZHEN LONG TERM INTERNATIONAL LIMITED and Shenzhen Meixin Electronics Co., Ltd. explicitly support logo printing, custom color schemes, and packaging labels—suitable for brand-differentiated retail or B2B reseller programs.
What are standard payment and shipping terms?
Common payment methods include T/T, L/C, and platform-mediated escrow. Shipping options range from express (DHL, FedEx for samples) to sea freight for container loads. Clarify whether pricing is FOB (origin) or includes CIF (destination port) charges, especially for orders exceeding 100kg.
