Help with ram compatibility

[viper6332]

I recently bought a new kit of ddr4 corsair vengeance pro ram to add to me prebuilt pc and its the same make and capacity as the ones that came with my pc but i have been getting random stutters in windows and memory blue screens so i contacted corsair and was told by them that prebuilt pc ram and off the shelf ram cant be mixed and i would have to buy another kit and take out the prebuilt ram even they themselves sent me one new stick to replace one of the prebuilt ram sticks because the leds went bad so i was just wondering if anyone can confirm what they said before i buy more ram or are they talking out of their ass to get me to buy more ram.

Hmm.. That sounds pretty weird, in theory they just mix just fine, worst that can happen is running on a slower speed.

Try running the system purely off of the newly bought ones and see how it reacts to that.

 

GL!

I will do thxs, it just did not make sense they are the same make and model same speed and size so i just assumed it would be plug and play as i have seen loads of youtube videos with people building pcs with ram from different boxes of the same make but they told me it all had to come in the same box to be compatible
