[Discuss] OT - Memory Upgrade

[jdmulloy at gmail.com (Joseph Mulloy)]

What's the motherboard model?

All slots run at the same speed. It lists two different speeds that it
supports, it's not that one slot is one speed and the other is the other.
Ideally you should get memory that all matches in at least speed if not
size. Matching memory helps with running multiple channels in parallel. I'd
buy the faster of the two supported speeds, which is DDR-1333 especially
since that's what you already have. Technically faster memory can run
slower if the system needs it to. So if you did buy 1066 ram your existing
1333 might be slowed down to 1066 and you'd lose performance.

If what you already had was 1066, I'd still recommend getting 1333 so that
I'm the future if you got 1333 to replace the 1066 you'd get more
performance.

Tldr, buy 1333 ram.
