thnx for paying attention. m going for a dual channel memory setup.these are the ram sticks - Corsair Vengeance 8GB DDR4 LPX 2400MHz C16 RAM and ZION 8 GB DDR4 PC 2400 UB DIMM-(ZHY24008192)DESKTOP RAM. why bother with two different brands? one of them is quite cheap compared to the other. my motherboard is Biostar b150 ver.5.cpu is i5 7400. once again thnx for ur attention.
