Adding ram over time question

Postby montyjnc » Fri Oct 20, 2017 4:10 pm

Hello,

Recently, I have been building a new computer, and I was wondering about how much ram to purchase. I have an X99 mobo and i7 5820k, so I eventually hope to have 128gb. Is it a bad idea to buy the ram.over time in 32 gb chunks (16gbx2 ddr4)? Someone mentioned something to me about ram being matched when it's made, and that I should buy it all at once, so the ram is "matched"? I was hoping to start with 16gbx4 and then add the next 4 sticks as needed.

My personal inclination would be to buy the full amount of RAM initially if feasible, for good measure, so as to be absolutely certain that it's fully matched (in case the same make/model/specification of RAM board isn't readily available later). However, if you were very careful about ensuring that memory boards were exactly matched in the specific slots that the motherboard's user guide requires (or globally, for good measure, in case the motherboard doesn't handle different specifications/latencies on different sets of slots reliably) then it should theoretically be fine to add some later. Check the motherboard's user guide carefully.
Best regards,
Martin.

I assembled my own i5 HW computer. When it came time to bump up the memory about a year and a half later, I made sure to purchase the exact same RAM spec and even the same brand to ensure compatibility. I guess I was fortunate that my original RAM was a popular brand name and spec (Patriot/1600/DDR3) which is readily available.

128GB is for people who have no cost limitation, to be able to load the largest sample sets in the very highest quality.
64GB is for people who want to be reasonably up to date with the largest sample sets
32GB is for standard users, who are willing to accept some compromises regarding the largest sample sets
16GB is still sufficient for a majority of sample sets, but quite limiting regarding several high quality releases from the last years.

Purchase the 64GB now -- I think that is what you are planning. While we will likely see the need for 128GB sometime in the future that wont be right away. Add the next 32GB when possible, ideally with an exact part# match. That gives 96GB which will likely be sufficient for the five year life (plus or minus) of the computer. Right now I'm not aware of a sample set that cannot fit within 64GB with small adjustments. I have all 6 channels of Goerlitz at 24-bit using a bit more than 70GB.
