As above really I have a laptop with an I5 11400 cpu and 16GB 2x8GB of 3200Mhz DDR4. Under the memory frequency tab on CPU Z it shows as 798Mhz. Windows system shows the speed as 3200Mhz but this is not a load test i believe ?

Is this normal or an issue with CPU Z or something going on with my laptop RAM ?

Thanks in advance
 
Could be the case of memory downclocking when idle. Modern laptops really do try to save every watt.
How do the timings look in CpuZ at that speed?

Put some load on cpu then check again. DDR4-3200 ram should show as 1600MHz in CpuZ.
 
Under load it still shows 798Mhz on CPU Z but HWinfo is showing as 1600mhz. Tbh I’m thinking it might be a reporting error with CPUz ?
 
DDR stand for Double Date Rate, so some apps show the single rate, which in your case is 1600 as double rate would be 3200. It's still possible that your PC runs it at a lower frequency when not under load.

As long as the profile is set then it should be fine.

I downloaded the latest from the site not sure if it’s been updated or not.

Was exoecting to see 1600 in CPU Z but it only shows 798Mhz even under load. Hw info shows 1600mhz. Its a laptop so not too many settings for profiles as far as I can tell.
 
Looks like it's using a correct SPD profile (according to the CAS# etc in use), so yep I'd put it down to a display error / CPU-Z/Win11 bug rather than an actual performance issue.
 
CPU-z always displays memory in that way has done for years it never reports the correct speed of the memory ?

800 x 4 = 3200mhz

1600 x 2 =3200mhz

Look at the Max-Bandwidth box on the right screenshot shows you the 1600mhz in brackets..

Showing 1/2 speed I agree with and is what it normally shows, but where does the 800mhz come from?

3200 divide by 4 (ie DDR4) = 800mhz

if it was something different like 633mhz then I would look into it but multiples of what its rated for I wouldnt be worried.

CPU-Z wont even detect the 3200mhz RAM in my 11th Gen laptop ! Both screens completely blank.

I dont need to be worried that I havent got any ram do I ? :cry:

You don't divide by 4 because it's DDR4 - it's still only Double Data Rate, not quad pumped.

My AMD based DDR4 system shows 1600mhz for 3200 rated ram - which is as you would expect. Anything showing 800Mhz is either a display bug (or the RAM would be running at half it's rated speed i.e. 1600Mhz, PC4 12800)
 
I see what you mean but I didnt mean 4 x because its DDR4 I didnt explain myself properly.
I have seen it in the past though 3200mhz represented as 800mhz for example thats what I was trying to say.

What I was trying to show was if it isnt a multiple of 3200 then it is probably more than a bug.
