Memory Problems

[Malafor]

Hi All,
I am having some memory problems or could it be my mobo.

Sys Specs.
ROG STRIX X470-F GAMING
Ryzen 7 2700x
16 gig G Skill Trident z 3200mhz

About 2 weeks ago i had 6 power cuts in about 30 mins so my pc was on then off and would restart its self due to the power cuts only lasting a few seconds.

After the last power my pc would'nt start and i worked out my main hdd had died i thought ok i would put my os ( win 10 ) on an ssd and all seemed fine pc started ok etc.

Then i noticed my ram speed was only running at 1600mhz but still showed 16gig So i rebooted in bios and my settings had'nt changed and memory was set to run at 3200mhz.

So i thought i would remove the dimms and just check that they were seated ok in B2-A2 and i swapped them round booted into bios again check settings were ok then went into windows.

Then i check my ram speed ( i used task manager and cpu-z ) and it showed only 8 gigs so i swapped them back again and it showed 16gig at 1600mhz.

I then bought another new 16 gig skill trident z and tried but got the same results.

Could it be the mobo went faulty with the power cuts ?
Or am i missing something ?

Any Help or info would be great.

And thanks in advanced for your help.
