Single 32gb DDR4 RAM vs 2x16gb
-
I just bought a pre-built desktop from Dell. I opted not to upgrade the memory as it was much more expensive to do through them.
My system is only coming with a single 8gb RAM stick which is obviously unacceptable. The motherboard has 4 RAM slots and supports up to 128GB.
I'm looking at single 32GB sticks vs 2x16. The single sticks are appealing to me because it makes it easier to upgrade in the future. I could eventually have 32x4 to make 128GB.
Now I don't see needing more than 40gb currently which is why I was thinking 32gb would be fine.
Ok that's alot of rambling... My main question is single stick performance vs using RAM in channel. What would you do?

As a general rule, I always try to use as many RAM sticks as the controller has memory channels. Until recently you could assume 2 channels per CPU in a desktop, but AMD has changed that recently with some of their midrange to high end desktop CPUs.

I think all the CPUs that supports have dual channel memory controllers, but I haven't looked them up to be sure.

@irj I would go with 2x16GB in dual channel mode so that you can have better memory performance.
Performance impact will depend on what your workload is,
We put single stick in desktops where performance is not important, but if you go with Ryzen 5000, I would go with dual-channel.

That case is just so ugly!

I love the white one. The black case I think they could have done much better.
I'm not a fan of windowed cases with a ton of lights.

BTDT. I would go with two 32GB.
The future is uncertain and it's much easier to just get what you might need right now. If you can imagine needing 40 GB I'd do 2x32GB right away. Then you have optimum performance and the same memory on both.
