About ddr3 4gb
Where to Find DDR3 4GB RAM Suppliers?
China remains the central hub for memory module manufacturing, with Shenzhen-based suppliers dominating production of legacy DDR3 components. The city’s electronics ecosystem supports a dense network of component manufacturers, packaging facilities, and logistics providers, enabling rapid prototyping and high-volume output. Key advantages include access to mature supply chains for DRAM chips and PCB substrates, localized testing infrastructure, and streamlined export operations through the Port of Shenzhen.
Suppliers in this region specialize in cost-effective DDR3 solutions for industrial applications, legacy systems, and emerging markets where DDR4 adoption remains limited. Production is typically organized around modular assembly lines capable of handling both standard and customized configurations. Buyers benefit from short lead times (average 15–20 days), competitive pricing due to economies of scale, and flexibility in packaging, labeling, and compatibility tuning. Most facilities operate under ISO 9001-aligned quality frameworks, though formal certification varies by supplier.
How to Choose DDR3 4GB RAM Suppliers?
Procurement decisions should be guided by three core evaluation criteria:
Technical & Quality Assurance
Verify that suppliers conduct functional testing on assembled modules using automated test fixtures. While explicit ISO or RoHS certifications are not consistently documented in available data, performance metrics such as latency consistency, voltage tolerance (1.5V standard), and compatibility across motherboard chipsets serve as indirect quality indicators. Request validation reports for JEDEC compliance, particularly for industrial or embedded use cases.
Production and Operational Capacity
Assess operational scale through key performance indicators:
- On-time delivery rate exceeding 97% indicates reliable logistics execution
- Response time under 4 hours reflects strong customer service infrastructure
- Reorder rates above 50% suggest customer satisfaction and product reliability
Cross-reference these metrics with online transaction volume (e.g., US $190,000+ annual revenue) to estimate production throughput and market presence.
Customization and Transaction Security
Prioritize suppliers offering customization options such as heat sink design, color coding, branding labels, and packaging variations—indicative of flexible production lines. Confirm support for small-batch trials before scaling. Utilize secure payment mechanisms and request sample batches to validate signal integrity, boot stability, and thermal performance prior to bulk ordering.
What Are the Best DDR3 4GB RAM Suppliers?
| Company Name | Main Products | Online Revenue | On-Time Delivery | Response Time | Reorder Rate | Min. Order Quantity | Price Range (USD) | Customization Options |
|---|---|---|---|---|---|---|---|---|
| Shenzhen Macroway Technology Co., Ltd. | RAMs, CPUs, Hard Drives | US $300,000+ | 99% | ≤6h | 49% | 1 piece | $4.77–$26.05 | Yes |
| Shenzhen Juhor Precision Technology Co., Ltd. | RAMs, Hard Drives | US $10,000+ | 75% | ≤4h | <15% | 1 piece | $3.33–$26.05 | No |
| Shenzhen Aoyi Technology Co., Ltd. | DDR3 Memory Modules | US $190,000+ | 100% | ≤3h | 55% | 10 pieces | $2.55–$7.80 | Yes |
| Dunao (Guangzhou) Electronics Co., Ltd. | Gaming PCs, Motherboards, RAM | US $1,200,000+ | 97% | ≤2h | 53% | 100 pieces | $2.36–$7.64 | No |
| Shenzhen Flashnoble Technology Co., Ltd. | DDR3, DDR4, DDR5 RAM | US $5,000,000+ | 98% | ≤4h | <15% | 100 pieces | $2.67–$90.75 | Yes |
Performance Analysis
Shenzhen Aoyi Technology stands out with a perfect 100% on-time delivery rate and 55% reorder frequency, indicating strong reliability and customer retention despite moderate revenue. Dunao (Guangzhou) Electronics demonstrates high operational efficiency with sub-2-hour response times and a robust 97% delivery performance, supported by large-scale production capabilities reflected in its million-dollar revenue. Shenzhen Flashnoble leads in financial scale but has a low reorder rate, suggesting potential gaps in post-sale satisfaction or niche market positioning. Suppliers like Macroway offer low MOQs (1 piece), ideal for sampling and small deployments, while others require bulk orders (100+ units), favoring high-volume buyers seeking unit-cost optimization.
FAQs
How to verify DDR3 4GB RAM supplier reliability?
Evaluate on-time delivery records, response speed, and reorder rates as proxies for service quality. Request sample modules to test compatibility with target systems, focusing on SPD data accuracy, stable operation at rated speeds (e.g., 1600MHz), and thermal behavior under load.
What is the typical MOQ and pricing for DDR3 4GB modules?
MOQ ranges from 1 piece for trial orders to 100+ units for bulk pricing. Unit prices vary between $2.36 and $26.05 depending on configuration, brand, and order volume. High-volume buyers can achieve prices below $3 per unit.
Do suppliers offer customization for DDR3 RAM?
Yes, select suppliers provide customization in heat sink design, label printing, logo branding, and packaging. These services are typically available upon request and may require minimum batch sizes.
What are the common lead times for DDR3 4GB RAM shipments?
Average production and dispatch lead time is 15–20 days. Air freight adds 5–7 days for international delivery, while sea shipping may take 25–35 days depending on destination.
Can I request samples before placing a bulk order?
Most suppliers allow single-unit purchases for testing. Sample costs are generally non-refundable unless offset by subsequent bulk orders. Confirm sample availability and return policies before procurement.
