Should 2 ram sticks operate at same speed?

Been having issues with my windows 8.1 booting, so every time I connect the hard drive with it on(have a w7 drive as back up) it would the slow to load and if it doesn't crash it would go straight to bios and then loop round to doing the same thing once I get a blue screen error unless I get really looking to get recovery options, anyways that's not Important, what is, is every time it boots to bios I always notice my Memory running at different speeds and the drop down option doesn't do anything to match them??

Is that normal?

I have 16gb corsair smx3 1600mhz ram, but it wasn't a dual kit, I added the 2nd one later date, but the one reads 1600 and the other reads 1333, I selected that overclock option or whatever it is(xmp or something) thinking that is how to fix it, but nothing I do changes it and while the performance can be up and down depending what's installed etc I can't tell if the slower speed is having any effect?
 
It might not work in duel channel mode if it's not a matched pair, however it should still work, I'd expect both sticks to run at the lower speed of the two if they are different spec.

You might have to manually set the ram speed if they are different.
 
Thanks for reply.

They are both identical or least what the label says, the extra ram came from zon(not where I got my system) so I made sure it was the correct speed model, they both xms3, I understand the mix ram as I've done it many times odd times on purpose, but those wasn't keeper systems.

I don't always understand most of what is in a bios, but I thought I was able to change some things in terms of the memory, but still reads the same.

Got a new case so I'll check the labels as I swap over just in case.


My board is the Asus H81M-Plus, I know it supports single mode hence only 1 stick to start With.
 
Not identical at all then - probably using different ram chips and IC's

Show us a CPU-Z screen - memory tabe and spd tab
