How do you tell the generation of a memory stick? Analysis of popular technologies across the network
Recently, with the popularity and installation boom of DDR5 memory, how to identify the generation number of memory modules has become a hot topic. This article will combine the hot content of the entire network in the past 10 days and provide you with a detailed analysis of the memory generation identification method through structured data.
1. Memory algebra key identification method

Memory generations (DDR, DDR2, DDR3, DDR4, DDR5) can be quickly differentiated by:
| memory algebra | Notch position | Number of pins | Working voltage | Typical frequency |
|---|---|---|---|---|
| DDR | Left center | 184pin | 2.5V | 200-400MHz |
| DDR2 | center | 240pin | 1.8V | 400-1066MHz |
| DDR3 | Right center | 240pin | 1.5V | 800-2133MHz |
| DDR4 | right near center | 288pin | 1.2V | 2133-3200MHz |
| DDR5 | Center slightly to the right | 288pin | 1.1V | 4800-8400MHz |
2. Popular discussion: How to choose between DDR5 and DDR4?
According to recent e-commerce platform data, searches for DDR5 memory increased by 300% year-on-year, but price is still the main point of controversy:
| Comparative item | DDR4 | DDR5 |
|---|---|---|
| 16GB single average price | ¥200-350 | ¥500-800 |
| Mainstream platform compatibility | Intel 6-10th generation/AMD AM4 | Intel 12th Gen+/AMD AM5 |
| Game performance improvements | base value | +8%~15% |
3. Practical guide: 3 steps to confirm memory algebra
1.Look at the label identification: Regular memory modules will be clearly marked with words such as "DDR3L" and "DDR4 3200".
2.Check SPD information: Read the SPD information of the memory module through tools such as CPU-Z and directly display the algebra.
3.Measured physical specifications: Use calipers to measure the length of the memory module (DDR5 standard size 133.35mm) and the notch position.
4. Association with recent hot events
•Micron DDR5 price reduction event: Starting from June 8, some models have dropped by up to 20%, triggering heated discussions in the installation circle.
•AMD Zen5 support verification: The latest test shows that DDR5-6000 is the sweet spot frequency of the AM5 platform.
•Fake DDR4 retrofit kit: Shenzhen seized a counterfeit toolkit that tampered with DDR3 labels into DDR4.
5. Advanced skills: Hidden parameter identification
| Parameter type | Identification method |
|---|---|
| OEM special strip | Check the FRU number on the PCB |
| Overclocking potential | Check the die number (such as Samsung B-die) |
| ECC check | Observe the number of memory chips (ordinary strips are 8/16) |
Through the above systematic identification method, you can quickly and accurately determine the generation of the memory module and avoid purchasing incompatible or counterfeit products. Consumers are advised to give priority to formal channels and keep complete proof of purchase.
