I need help..

[Gandown]

So basically I have a 1x8gb ddr4 3200 mhz of ram, my task manager, cmd prompt say that I'm running at 3200mhz but my cpu-z and hwinfo64 say MY RAM is running at 798,1 which is 1600 when multiplied by 2. Can someone explain me whats my actual ram speed

Oh btw, these guys have the same problems but no one answered their questions either.

I believe that 3200 is only the highest nominal speed the system is reading from the stick's SPD chip, not the actual speed it's running at.

 

CPU-Z always reads accurate data, so it certainly is running at 1600. Go change it in the BIOS if possible.

Some laptops dynamically downclock the memory to save power. Try stressing the CPU to see if it comes up to 1600 MHz. What CPU?

It's an i5 11400H and by stressing, uhh..

It seems like my bios doesn't have XMP, maybe because It's a laptop and the manufacture doesn't want any consumers to accidentally burn their laptop

the numbers kinda dont change when i stress my cpu

Check with other software, like for example Aida64

Check the SPD profiles .. see the SPD tab in CPU-Z  or the list of profiles in Aida64

 

It's possible the laptop reduces the frequency of your ram when the computer idles, to save power. 

 

You can try running something cpu intensive, for example use 7zip to compress a folder just to give your CPU something to do.  Refresh Cpu-z or Aida64 and see if the numbers change while the compression is performed. 

 

Go in BIOS if it stays at 1600 mhz and see if you have some options to configure the memory. 

 

You can do it from Windows, click on power, then hold shift and press the reset option, and you'll have an advanced page where you can select to go in bios. Something something UEFI settings...

I tried to do the cpu stress test then re-open CPU-Z and HWINFO64, the numbers are still 798.1s and my BIOS doesn't have any options to configure the memory either.

In UserBenchmark my ram looks like it's running well ?

[Gandown]

what does maximum supported means..?

[mariushm]

Well , according to that, your ram runs at  3200 MT/s CL22  ... more precisely it runs at 1596.1 Mhz x 2 = 3192.2 MT/s  ... close enough to 3200. 

 

DDR 3200 runs at half the advertised frequency in reality.

So my ram is working perferctly fine then ?

yes
