Confused about my Ram XMP - seems to not work

[Tofu]

Hi Guys,

Posting this on behalf of my German friend, so sorry about some of the linked pictures being in Deutsch, but you know what you're looking at anyway.

He bought Patriot Viper 3200MHz 2x8 Gb as an upgrade from 1 single stick of 8gb Crucial ram.

He is using a MSI B350 PRO-VDH AM4 with a Ryzen 5 1400.

I'm far from the source of all knowledge when it comes to computers, but compared to me he has no clue. So I told him how to enable his XMP in his bios, which he did. The motherboard even confirms these changes by stating 'DDR Speed 3200' at the top. (See 2 images linked at top)

However when he boots into Windows, task manager says 'Memory Speed: 1600'. I wasn't too concerned about this, because obviously DDR means double data, and 1600 x 2 is 3200. Although I still found this strange, because in task manager on my computer it actually states 'Speed: 3200'. (See image linked at top)

Finally, I asked him to open is Command Prompt to check his memory speeds, and this reads: 'DIMM 1 1067, DIMM 1 1067'. Again, in my command prompt it shows me 3200, 3200.

If anyone could explain to us why this isn't working that would be amazing.

Thanks!

1067 is when it's running at the default 2133.

1600 = 3200

[_I_]

*1600mhz = ddr 3200

Everything correct from the image.

Also when using software tool like CPU z, or whatever, it will display ram frequency by half. 16+16 = 32.

Thanks Doc,

Do you know why command prompt shows a speed of 1067? When my computer displays it correctly as 3200? I think this is the bit that confused me and made me feel like something was wrong.

Thanks!

my comment: it is ddr ram and two times 1067 is then twice the value:2133. this the default speed with ddr4. in my pc it is the same. i dont use xmp profiles. the xmp profiles have higher clock speeds. everything with your friends pc is fine imho

You better be manually setting RAM frequency, timings, and the DRAM voltage, otherwise you're holding back your CPU by quite a bit.

That's the point of docp/xmp it does all those ram setting change for you.
