Hi People, has been a while since building a new rig from scratch so google answers most questions but not all ... Thank god for forums. Motherboard is picked (X299) so 8 memory slots ... so it's a matter of 8x8 units/sticks of mem (Xxxx) to get 64 gb verses 4x16 ? 1) Is it cheaper per gig to go with 16gb per stick or 2x8 ?? 2) is there any advantage/disadvantage with through put and or latency/overclock ability populating half or all the slots with a given mem module making a total 64 gb population ... many thanks for all who can help me out.
