if you're planning on installing those RAM in a Macbook - don't even waste your money or time. there is a 90% chance that it won't work.
don't get me wrong - some people have had success in getting their Macbook to boot with those RAM installed - but they were installing them in a 2011 Macbook Pro which uses the 1333MHz version. Yours however, uses the 1066MHz. Why take a chance?
I once installed 1333MHz RAM in my Late 08 Macbook Uni - worked for a while - couple of months later, had nothing but issues - after i reinstalled the old RAM, my Macbook was back to normal.
There's no harm in trying - but it's best to install RAM that spec'd out for your Macbook.
Also, spend the extra $5 to $10 to install Mac Certified/Tested RAM - better for your Macbook. Sometimes generic RAM works if you get the right timings - but most of the times they don't - just search this forum and you'll see how many people bought non-Apple Certified RAM and have had nothing but issues.
Good brands like Crucial - Corsair - Mushkin - G.Skill - Kingston (non Value) - Patriot Mac Series are a good start.
I personally use G. Skill 1066MHz RAM in my late 08 Macbook Uni. Crucial 1066MHz RAM in my late 2009 Macbook White. Patriot Mac Series in my late 2011 Macbook Pro - all with no issues at first install.
In any event - good luck with your ram transplant and hopefully it all goes smoothly with you.
Good brand - never had any issues with G.Skill.
