Does APU use RAM?

Also, how much RAM do I need for Ryzen 5 2400g?

For our testing, we are running the Ryzen 5 2400Gat three different memory speeds, 2400 MHz, 2933 MHz, and3200 MHz. While the maximum supported JEDEC memory standardfor the R5 2400G is 2933, the memory provided by AMDfor our processor review will support overclocking to 3200MHz justfine.

Also, does adding more RAM increase integrated graphics card performance? Adding more RAM will improve your systemperformance since it'll have more breathing space,but it won't increase graphics memory. No it won't. Thegraphics card has memory that is only used on thegraphics card itself.

Also asked, can you use a graphics card with an APU?

While desktop APUs from AMD are good enoughcompared to intel integrated graphics, they don't provideyou with enough performance to play games on high or ultrasettings. If your motherboard has a PCIe x16 slot, you candefinitely add a GPU. Anything more powerful and your APUwill bottleneck the GPU.

Does memory help gaming?

First, most of the processing on a game is executed bythe video card. Second, more RAM only improves the computerperformance if there is a very little amount of memory forthe program the CPU is running and the processor have to use thevirtual memory feature, swapping memory data with thehard disk drive or SSD.
