Note: If you're going with 2 different speed of ram sticks, they will always run at the minimum speed whichever stick has the lowest.This video actually expo Yes, you can use 4GB and 8GB RAM together. But you may experience a performance drop while using RAMs of different sizes. But you can reduce that performance deficit to some degree by using two different-sized RAMs of the same bus speed. But, Tech experts always opt for using the same-sized RAMs. Curious to know can I use 8GB and 16GB RAM together. You can use 4GB RAM and 8GB RAM together, but use them with caution. You must understand the risks of mixing the RAM sticks. They must be compatible both with the processor and one another. The motherboard must support the combined RAM capacity. This is why RAMs are often sold as a matched kit of 2x4GB, 2x8GB and so on. When upgrading RAM on a PC one FAQ is whether it’s possible to mix modules of different capacities (e.g. pairing 8GB + 16GB together). Mixing RAM modules of different sizes is fundamentally fine so long as the generation, speed and primary timing are matched exactly or at least as closely as possible.
The mixed RAM will run on Flex or Asynchronous Dual Channel Mode. This mode will give you better performance than single-channel mode but not as close to dual-channel mode. Consider a system with 4 GB and 8 GB memory modules running on a dual-channel setup. Here, the 4 GB module and the 4 out of 8 GB RAM (in total 8GB) will run on dual channel
Whether you notice or care about the speed difference is up to you. If you don't mind slower ram performance after 16GB of ram is used when using 8Gb and 16GB for 24GB total, then go for it. Just know that the chances of incompatibility are much greater when running miss matched modules. Buying your ram in 2x or 4x kits is best for compatibility. You can use 8GB RAM and 4GB RAM together, but doing so can affect performance. Although you’ll have a total of 12GB RAM, it will be slower than using two memory sticks of the same size. Can I put 8GB and 16gb RAM together? In theory, you can easily connect a stick of 8 GB and a stick of 16 GB RAM together in your computer. While you can technically mix speeds, there is one important thing to note: your DRAM would all run at the speed of the slowest module. For example, if you have a DDR3 1333MHz system and install a second module at 1600MHz, they would both run at the 1333MHz speed. The same thing happens with modules that have different latencies. 4GB to 8GB. 4GB of RAM is recommended as a minimum configuration for the typical productivity user. 8GB to 16GB. 8GB of RAM is the sweet spot for the majority of users, providing enough RAM for virtually all productivity tasks and less demanding games. 16GB or more. 9AAm.
