Too expensive to buy second hand memory How to measure?

The memory usage seems to be continuously increasing. Memory usage is still climbing! When will the memory drop? We might not see a decrease until at least the second half of next year. But what should we do now? Some people may consider buying second-hand memory. As long as the memory isn't used for a long time, its durability shouldn't be a concern. However, this approach feels a bit uncertain. Just recently, I added a piece of memory to my computer – yes, it’s second-hand. I thought about it carefully and decided to check it out using some software! Make Sure Not to Miss Memory Specifications In recent years, upgrades for computers have mainly focused on DDR3, DDR3L, and DDR4 memory. DDR2 users should probably move on. Honestly, purchasing new DDR2 memory isn’t ideal. So-called "new" DDR2 memory often comes from underground factories and is either refurbished or newly manufactured. When it comes to DDR3 memory, the main specifications include DDR3 1066, 1333, and 1600. When upgrading, these specifications serve as a baseline. For instance, if your current memory is DDR3 1066, it doesn't really matter which one you buy. In practice, the memory will run at the lowest frequency, so there's no point in considering DDR3 1066 if you're using DDR3 1333. This would result in running the memory at DDR3 1066 speeds, leading to significant performance loss. There is a particularly important specification: DDR3 also has a low-voltage version called DDR3L. The 'L' stands for low, with a working voltage of only 1.35V compared to DDR3's 1.5V. Before purchasing memory for either a laptop or desktop, make sure to check what your computer supports. You can use CPU-Z to check memory details. DDR4 memory also has plenty of second-hand options available. If you’re using a 100-series chipset motherboard, you might want to consider getting a second-hand memory module to create a dual-channel setup, which can significantly improve performance. In terms of specifications, DDR4 2133 should suffice. Although some motherboards technically support DDR4 2400 or even higher specifications, I personally don’t find it necessary. For users with 200-series chipsets, DDR4 2400 is likely the best choice, especially for those using 7th generation Intel Core processors (which have integrated memory controllers supporting DDR4 2400). Lastly, there’s also memory specifically designed for the AMD platform, starting from the DDR2 era. I won’t go into detail about why AMD users get half-price memory, but I’m sure you know. Take Time for Yourself When buying second-hand memory, the most crucial step is to clearly communicate with the seller before making a purchase. Always leave room for retreat. For instance, if you're dealing with hand-packaged memory, this is a basic requirement. Whether you're buying from a second-hand personal seller (especially those selling via platforms like Taobao), always clarify with the seller beforehand. Even explain that if there are any compatibility issues, you can return the memory. Additionally, ensure you understand the memory already installed on your computer. Running Software Tests Speaking of testing, this is where I excel. I recommend using MemTest64 to test the memory (you can comment “memory test” to get the download link: http://pan.baidu.com/s/1jIpCmF0). This is a portable version. After downloading and extracting it, you don’t need to install anything. Just double-click to run it. On the interface, click “Begin Test” to start the test. Note that during the test, the computer cannot perform any other tasks as the memory will be fully occupied. A full test takes around two hours. If there’s a memory error, MemTest64 will stop automatically, which is quite intuitive. If the test runs smoothly, it means the memory itself is fine, and you can use it with confidence. If you’ve combined old memory with newly purchased memory and both pass this test, it indicates there’s no compatibility issue. Apart from MemTest64, there are many other testing software options. I highly recommend checking out the list of 7 commonly used PC test tools in my previous article. These programs can not only test performance but also play a critical role in "stress testing," which essentially loads the system to see if there are any operational errors. I believe these tools can be helpful for everyone. If you’re interested, feel free to give them a try.
