Yes, you can use different RAM cards in your computer, but it's important to ensure they are compatible with your motherboard and have similar specifications, such as speed (measured in MHz) and type (e.g., DDR4). Mixing RAM with different specifications may lead to instability or cause the system to run at the speed of the slowest module. Additionally, using RAM from different manufacturers may affect performance, so it's generally recommended to use matched pairs for optimal performance.
The RAM is use in laptops are SD-RAM
A computer will not accept a new RAM that has a different voltage than the factory installed RAM cards.
One can purchase Dell ram cards from Dell's website. They come in many varieties. They come in 1GB, 2GB, 4GB, 8GB, and 16GB. The ram cards also come with different connector types such as DDR, DDR2, and DDR3.
Kingston makes several different types of RAM hardware, including system specific RAM and a value priced line.
Yes, video cards generally have PCI-E pin arrangement. I have seen a couple with PCI before, but nowadays i think companies are leaning towards the PIC-E now.
Northbridge
Most if not ALL modern video/graphics cards use both RAM from the MoBo and The dedicated RAM on the card.
The reason for RAM not being intergrated on a motherboard is because theres different RAM sizes and how much RAM a motherboard can handle along with RAM speeds. My motherboard can handle up to 16gb RAM and that is equal to 4 4GB RAM cards and the speeds my motherboard can handle are 2000MHz.
No, you'l fry your motherboard, and ruin your entire computer, avoid mixing different DDR ram, and size. I suggest consulting a professional. CompUsa.
It’s generally better to replace the 2 4 GB RAM cards with 2 8 GB RAM cards for optimal performance and compatibility, as mixing different sizes can lead to suboptimal memory speeds and may not utilize dual-channel architecture effectively. Upgrading to a total of 16 GB (2x8 GB) will provide better performance for most applications. However, if you already have the 4 GB cards and want to save costs, adding the 2 8 GB cards can still work, just be aware you might not achieve the best performance possible.
Depending on what your motherboard can handle, all the RAM (regardless of clockspeed) will clock to the same speed.
No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
