Random Access Memory (RAM) is hardware that your computer uses to store information. Adding memory is one of the most cost-effective ways to increase your computer's performance. The Dell paměti branded memory offered in the memory selection tool undergoes rigorous testing and quality control to ensure that it will run on your particular Dell system, be fully compatible, and be supported by Dell. The use of unsuitable or non-branded products from other suppliers can lead to outages, which can in turn cause costs for the company and endanger the entire system. The memory currently offered may have a different speed than the original memory, but it is confirmed that they can work in the device. If you use different memories, the memory will run at the lowest speed used or at the highest speed supported by your computer.
