So I should be getting the same exact model right? with same speed?give name and model of old ram and will work single channel since it is not a dual kit .
So according to what you are saying, They will both run at 3000mhz but still perform in dual channel mode?regardless of what type of ram configuration you go for your mhz speed should be the same on all sticks , if you have 2 different mhz speeds the slower one will pull down the speed of the faster one.
