Single 16gb vs 2x 8gb ddr4 with 4 core ryzen

Computing_Now · Apr 7, 2017

I am thinking of getting a new ryzen system when the new cpus come out later (probably a 4 core one).

But I wanted to ask is there a huge performance increase by getting 2x 8gb ram modules rather than 1x16gb for gaming?

I like the upgradeability of a single one though. Is a single 16gb still acceptable in terms of speed?

Used with a gtx970.

Using all the RAM channels a CPU has will always maximize performance. Thinking that you can add an additional 16GB later may or may not work because even RAM with the same part number won't always play together. RAM purchased as a matched set is the surest way to get RAM that works together. It has been tested as a set.

Ok with my last computer I added a completely different ram module (different capacity even) at a later stage and I didn't notice any problem, what type of problems could occur?
But the two original ones were in the coloured slots and the other one was added to one of the black ones.

I was looking at one new motherboard but it only has 2 slots in total.

All I can do is suggest you search this site for "added RAM" and see how many threads there are with issues doing exactly what you want to do. That is why I will ONLY recommend matched set RAM purchases. You get a manufacturer's guarantee that it works together as a set.

This is a DDR3 article -- http://www.tomshardware.com/reviews/ddr-dram-myths,4155.html But the myths are all the same for DDR4.

Ok so you just have to buy what you need and if you want to upgrade in the future you have to throw it away and buy more from scratch.

While incompatibility CAN occur, it is HIGHLY unlikely.

I have mixed DDR1/2/3 sticks many times and have never had issues. The old Q6600 build I thew together for my mom has 3 different brands/types/speeds of DDR2 (4 sticks totaling 7GBs). I've never had a mismatch issue.

Don't let this guy scare you, it's isn't the 90s anymore.

andrewskaterrr :

No, it is much worse. Especially with Ryzen. It is new enough that even standard RAM kits can have incompatibilities. The BIOS has not been through enough revisions YET to guarantee stability, especially at XMP clock speeds -- which everyone believes they should be able to achieve, because it is advertised that way.
