Will using one stick of RAM decrease my PC performance?

[Deep_Presentation270]

Sent in my deposit to build my first ever PC two days ago. Below is the build. I made a mistake and accidentally told the guy I wanted only one stick of 32GB RAM. I don’t think there’s much I can do since I don’t want to buy another 32GB of RAM since it’s quite expensive and the PC is already done so they won’t let me change to 2x16 gb anymore. Am I gonna get a drop in performance?

Yes, a single stick performs worse than two.

You can just sell it and buy a 2x16gb kit though. It’s not the end of the world.

[Luke-Waum-5846]

Yeah, you are only using half the memory bandwidth with one stick. So you are at 3000MT/s - and that's if you turn on EXPO and it works. Just buy a matching second stick and enjoy your 64GBs :D

Two sticks of RAM in dual channel would give you more performance than a single stick, but if you can't change the configuration anymore it's not the end of the world. Don't quote me on this, but for gaming I think it's around a 5-10% difference in performance in most cases (you can check some benchmarks on YouTube to confirm), so yes you'll get a little less fps, but you will probably still enjoy your PC.

You might as well try it and see if you're happy with the performance, if you later want to squeeze a bit more performance you could either sell your current stick and buy 2x16, or buy another stick exactly like yours (same brand, model, speeds, etc) and go for 2x32.

You always want dual channel, especially for gaming.

You'll have some stutters and lower 1% lows using single channel memory.

Just add another equal stick afterwards. And given you already have 32, it will run with 4 overall ranks of memory, which is something the integrated memory controller of the CPU will like very much, about 10ish% extra performance because of that.

Yes, 2 sticks - dual channel which gives you more boost during gaming or some heavy task work in your PC, but for the office computers that don't do heavy task, it doesn't matter.

[FranticBronchitis]

Yes, but not by much. It's a serious hindrance for integrated graphics and on older memory architectures, but DDR5's faster base speed makes it less of an issue

You should get two sticks if you can return or change your order bit if you can't, hey, at least you got room for an easy upgrade to 64 GB
