[SOLVED] I have much lower performance than in youtube benchmarks

[Magmals]

APU - AMD Ryzen 3 4300G
RAM - 1x8GB DDR4-3200
MOBO - HP 87D6 (B550A Chipset)

I have recently bought a pc with an AMD Ryzen 3 4300G since for a budget APU it seemed to give crazy performance in benchmark videos.
I have recently bought GTA V and the results I got are ridiculous. On medium-high settings in 1440p he gets 30-ish Fps while I barely get 30 Fps on the minimum settings in 720p .

Also I noticed my Cpu and Gpu usage is on 40-50% all the time.

I don't know if there is a problem with my system or this guy is straight up lying about the specs he is using although it wouldn't make any sense for him to do so.

If useful these are all my specs in CPU-Z.

Your RAM is the issue.

I haven't watched the video but I can straight up tell you you're running in single-channel mode (meaning half the bandwidth of dual channel). If you want performance the easiest thing is get a kit with two RAM sticks.

Since GPU performance is closely tied to memory speeds, double the RAM speed will boost your performance by a lot

I didn't know dual channel was that important to performance, from low settings to high settings just by using dual channel is mindblowing, I will get another 8gb stick I guess.

I don't suggest buying any stick off the internet, it's best if it's the same manufacturer and model. If not you might need to spend loads of time tweaking the memory timings
