Hi, I bought a 4gb RAM upgrade on Amazon for my mid-2009 MBP for the upgrade to Lion, but when I opened it I realised it was one 4gb stick, not 2x2gb like I thought I had bought. I can't return it now, so I'm not sure what to do.

I know it's considered bad to have asymmetrical RAM, but is installing it next to one of my existing 1gb sticks better than just running on the one stick? Or am i best off just buying another one of these sticks to have 8gb in parallel?

It isn't too bad to have mismatched ram sizes. You'll still see a speed boost, but it won't be as big of a boost as 2x2Gb would be.

Itll be fine, just put both in, any RAM will help but not as much as a matching set would

The fastest RAM will auto-match speeds with the slowest and match the slowest stick's speed. There should be no issues with this.
