AMD integrated GPU RAM speed

[Yo1]

Hello, i recently bought a new laptop Lenovo v15 g2 ALC, with AMD Ryzen 5 5500u with integrated graphics, it also has 8GB of RAM clocked at 3200mhz. I need help understanding how come if my gpu is using system memory as its own vram, the speed of vram in amd radeon software shows 1333mhz, but the system ram speed is 3200mhz (1600mhz DRAM). I have set in bios maximum perfomance mode, and it windows power settings i have set best performance, i dont have any other settings in bios like XMP-like profile changing.

What does the system RAM speed actually say in CPU-Z?

[Yo1]

Here is the info from the CPU-Z about RAM speed and GPU memory speed. Also I attached info from the AMD Radeon Software.

Looks like it's running at the right speed, so it's likely the radeon software just giving generic info without actually checking.

Wait, how is it the right speed? Shouldn't the memory that GPU is using be the same speed as the system memory, since it's using part of the system memory, which is onboard ram, clocked at 3200mhz DDR, or rather 1600mhz DRAM. Even if its the single data rate transfer speed of 1200mhz, double that would still be 2400mhz which is obviously not 3200mhz. Im wondering is there a reason for different speed of, technically, the same physical memory of 8GB, divided into 6GB system ram and 2GB vram?

ATi?  Theres something wrong with your software...

You are getting 3 different ram speeds,  1600, 1333 and 1200... thats literally impossible,  especially with integrated graphics.  So the question is , is this the newest version of cpuz? And have you tried gpuz?

 

Lastly, are there even any issues or are you just asking why its showing all those different speeds?

 

Ideally you should use only 1 monitoring software,  id say hwinfo64 or afterburner perhaps.

And I just said that CPU-Z showed your memory running at the right speed, and therefore that the radeon software likely just says garbage or is not even intended to give the effective speed. 

Like "there is 1333/2666MHz RAM connected to the GPU" and it shows that without even trying to check if it's actually running at a faster speed. 

 

I'd just ignore what it says.

I have downloaded the software from official AMD website. If you're referring to the CPU-Z screenshot, i believe its just the logo CPU-Z is using and its outdated, it clearly says AMD Radeon Graphics. Also CPU-Z was also downloaded from their official site.

I see, well I think  @Kilrahis right, but still, you should use cpuz for cpu, and gpuz for gpu... or something else entirely (see my edit above)

 

I didn't have these issues with my

old 2200G... and I've never really used the amd software,  amd software is buggy, I don't trust it...

 haven't noticed any issues, i was just curious which of these was actually correct. I have tried hwinfo64, stable version 7.14-4610 and there again i get different results for the GPU memory clock. I will attach files for you to see.
