The density of a memory module is determined by the small black DRAM chips that make up the memory module. The fewer chips there are on the module, the higher the density. High density modules process the same amount of information at the same speed as low density parts, but they use fewer chips. Fewer components also cost less to manufacture, and the end user won’t notice a performance difference.
Will high or low density parts work with my original memory?
Your system will most likely accept either type without any issues, and we manufacture and sell both types of memory. However, if you are mixing the new memory with your existing memory, you may want to try to match the memory modules as closely as possible. It is possible, though not common, to experience incompatibility issues when trying to mix high and low density modules together. It is recommended to match your original memory as closely as possible for optimal performance.
Which is better, high density or low density?
Truly, there is no difference in performance to you, the end user. It can be likened to a lug pattern on a wheel. The wheels are going to work the same – the difference is in how they’re made. The only thing to consider is which type will be compatible with your computer. Any part that is recommended by the Crucial System Scanner is guaranteed compatible with your system when you order on Crucial.com. If you haven’t used the scanner just yet it can be found here.
Which one should I buy: high or low density?
You should always purchase whichever memory your system supports. In this case, buy the type that’s compatible with your system. If both types are listed, both types should be compatible. However, keep in mind that for optimal performance it’s recommended to have your installed memory match whenever possible.
