I bought a new pc set and they gave me two different RAM sticks. One runs at 26667Mhz (with no XMP option), and the other runs at 2133Mhz (with XMP option to 3000MHz).
I have a B550 Gibabyte Gaming X v2 motherboard, and I couldn't get them to run at same speed. Can this be done, or should I return this to the shop?
or if it came preinstalled; have them give you a 2x packaged set, not just two separate sticks.
or actually return the whole system. i would not trust dealing with a shop that could make this kind of mistake or that may have done it intentionally just to unload two sticks of RAM they had on hand.
sticks of RAM that are packaged together have been extensively tested to ensure compatibility.
buying two separate sticks, even if they are the same make\model, is never recommended.
