Question Sapphire Rx 570 8GB doesn't perform as same as the benchmarks on Youtube or userbenchmark.com

[FlashxDLOL]

Hello,
I built a new PC a few days ago. I've been playing Assassins Creed Origins since today, but have low FPS,like 30fps, on medium settings.
I got my drivers up to date and installed them from the website of the makers.
I ran some tests on Malwares or Viruses but everything is clean. I already made a new installation of Windows but it is still not working.

PC Built:

CPU: AMD Ryzen 3 2200g
GPU: Sapphire rx 570 8GB
Mainboard: Asrock B350M-HDV R4.0
PSU: Corsair 450w (checked if the powersupply is to weak but the power supply fits perfect in the build)
Ram: Ballistix sport 8gb ram 2666mhz
SSD: 250gb intenso
Got 3 fans in the pc: Front: 2 Back 1
All parts are new

You have a single stick of RAM?

Yes

It is more like a budget build.... I checked on PCPartpicker too, if the parts are compatible. There should be no problems

 

[MrN1ce9uy]

There's no problems with compatibility; however, you are not running dual-channel RAM. That can affect gaming performance.

System Requirement

• 500 Watt or greater power supply

Wouldn't the PC turn off when the PSU is to weak and does it affect the FPS?

 

[MrN1ce9uy]

Your PSU is not too weak. PSU requirements are general guidelines because a lot of power supplies are total crap. Yours is not crap. I would imagine single-channel RAM has an effect. It largely depends on the game.

But the results on userbenchmark.com say that the single channel ram should perform pretty good even though its a single channel ram.

That's a synthetic benchmark that's not even that great. Games are totally different.

I'll just buy a second 8gb ram stick.
thank you for your help
