1x 16GB stick ok?

[Harnser]

I want 16GB in a new build and it's cheaper to get 1x16GB than 2x8GB. Is that a problem?

I think you used to have to add RAM in pairs; is that still the case?

There is a performance hit from losing dual channel memory (you need two sticks for this to work).

Whether that matters to you vs the cost is up to you.

It'll work, but you'll be losing some performance. I wouldn't do it.

Single v dual channel ram can be a 20% performance difference.

Thanks all, going for two sticks.
