So I was checking some stuff in my BIOS to give my APU Graphics 2GB of VRAM,
and then I saw that after I changed the setting, my RAM was running at 1333 Mhz instead of the 2133 Mhz that it should run at.

Here are my specs if that helps:
AMD A10-7870K 3.9ghz to 4.1ghz
G.Skill Ares 16Gb 2133Mhz 2x8gb kit
EVGA 430W Bronze power supply
1Tb Seagate Baraccudda
120gb SSD Adata for Windows 10
No GPU since I use the built in R7 Graphics.

I really hope I can get some help and fix this Issue.

I think that the VRAM optimized memory might be running at 1333 MHz and that the other 14 GB of RAM is running at 2133 MHz. Now, if ALL of the RAM is running at 1333 MHz, undo the operation and see if the RAM goes back up in speed. 1) You might have messed with something you shouldn't have, and 2) The RAM already in the PC works as VRAM anyways, only using what it needs. At least that's how mine works (because I have an A6-3600 APU).

Is there a way to check that?

UEFI BIOS... if you could show me a screenshot of how you separated the RAM,that would be helpful. Take a photo with your phone, plug it into the computer, boot into Windows, and save the image to your PC. To show it to us, that's something I'd have trouble figuring out.

Here you go.

go to bios, advance mode, advanced tab, NB config, change integrated graphics from auto to force, and then change other setting from 1g to 2g

It does show the frequency for both ram sticks.

I set that already in the BIOS and it didn't do much

Then the system probably did the under clock to prevent instability. Running the memory without a cooler and at those speeds as VRAM could probably cause instability and errors or overheating. RAM speed doesn't really matter usually but as video memory there's not much to do. Though my system has 8GB DDR3 at 1333 MHz with an AMD A6-3600 and gaming hasn't ever been an issue.

But is there a way to prevent that under clock?

I wish there was, but unfortunately no. I think you should get separate memory for the VRAM. Something faster than 2133 MHz base clock (like 2GB DDR3 @ 2400 MHz), though with dual channels you might only get 8GB of real RAM. Then the whole iGPU thing about running some RAM as VRAM won't be an issue as the other RAM will still be running at full speed.
