However should you do plan to exchange the GPU, then be sure that to study find out how to take away GPU from the motherboard. 

Can The Motherboard Bottleneck RAM?

The motherboard is not well-known for bottlenecking RAM efficiency. Though, it does come together with assist points. As soon as once more, an outdated motherboard can’t assist the RAM you simply purchased to your PC to run sooner. That isn’t how issues work.

Your previous motherboard is more likely to have DDR slots to which you can’t join your RAM. Like GPU PCIe slots, RAM must be related to a DDR slot to switch knowledge out and in. Sadly, RAM is in contrast to GPU; it can’t be related to a unique slot than the one it’s designed for. For instance, DDR4 RAM can’t sit in a DDR3 slot.
