Accidentally bought one 16gb stick instead of two 8gb RAM

[CiaoChao]

I'm doing a new build and I spent the last of my budget on DDR4 RAM, but I was an idiot and accidentally bought a single stick of RAM of 16gb rather than two 8gb. I most likely just saw 16gb and instantly bought it without thinking due to the sale.

My motherboard supports up to 64gb and dual memory, would it make that much of a difference if I stuck with this stick for a while? Although I feel like it's a waste if I keep it now and buy two sticks later making this thing useless resulting in me wasting money. If I return it, I most likely won't be able to finish this build for a couple more days but I do need to get some work done.

Thoughts?

It will make very little difference using one 16GB stick compared to two 8GB sticks in dual channel. Use the single stick.

If yours is a Skylake gaming build and you have a separate GPU, than it probably won't make any difference.

The difference is negligible and you wont notice it. Actually is some cases single is better than dual. Take a look at this http://www.hardwaresecrets.com/does-dual-channel-memory-make-difference-in-gaming-performance/5/
Besides a single 16gb will allow for much better ram upgrade if and when required. (Between recently i chose a single 16gb over two 8gb for my build).
