Every tool shows memory as half the speed

[Niami]

Every tool I have (CPUZ, HWINFO, task manager, ryzen master) shows my memory as 1500MHz instead of 3000MHz. I know task manager is innacurate most of the time but even the more advanced tools show it as 1500MHz and was wondering if that's correct.

DDR(4, in this case) means double data rate.

 

 

2 x 1500 = 3000MHz

Long story short: your memory is running at the 3000Mhz, if CPU-Z/Task Manager/whatever shows 1500Mhz.
 

Long story a bit less short:

Your memory runs at 1500Mhz, which is (millions) of ticks per second. Per tick it can do two transfers (which is why it is called DDR = Double Data Rate), so it is running at 3000MT/s (millions of transfers per second). Manufacturers of memory/motherboards call this 'MT/s' unit 'Mhz', thus they (manufacturers) sell it as 3000Mhz.

CPU-Z reads it out the right way, thus 1500Mhz.

That is in fact correct. The tools show the physical frequency the sticks run at. The data rate however is double the physical frequency because the data transfer is triggered with every up and every down of the frequency. That's why it's called DDR (Double Data Rate)

now that you've verified its running at the advertised speeds, time to overclock!

Thanks for confirming, I was sure atleast one of these tools showed the doubled speed at sometime and was confused.

It's already overclocked from 2666 . I was sure that one of the tools I mentioned showed the doubled speed at sometime while I was overclocking and was a bit confused when I was looking through HWInfo recently.

If I remember correctly, Windows Task Manager used to show the MT/s as Mhz (so 'incorrect' 3000Mhz instead of 1500Mhz). But I am not sure about that.

Although Windows has been known to show incorrect units of measurement (*cough* GB vs GiB *cough*)
