A few questions about RAM!

Welcome to MR.

Please try the Forum's Search function - this question has been asked and answered many times before, including 1 hour ago...

The OCZ RAM at 800 MHz may work in Core2Duo products. However there will be no speed increase, because the Mac's memory controller is limited to 667 MHz, so there is no point in buying 800 MHz RAM. The vendor (NewEgg) does not guarantee compatibility, and they have a restocking-charge policy on returns. Plus this is far from the best price.

On MR, the most often recommended vendors are Crucial (use the link at the top), OWC (Macsales.com) and Data Memory Systems who have a guaranteed compatible 4 Gb kit for $238 with a free shipping option, and great customer service.

Again, as CanadaRAM said...those questions have been asked many times. No, upgrading the memory does not void the warranty, because memory is supposed to be a user-serviceable upgrade. Crucial memory is fine, but usually too expensive. No, there's nothing magical about Apple RAM, it's no better than a decent third-party brand. It all comes from the same two or three manufacturers anyway, most of the time. Lots of people on here (including myself) have had great success with G.Skill and OWC memory, and those are usually very reasonably priced. Both of those you linked to are WAY too expensive. You shouldn't pay more than $240 for a 2x2GB kit, max.

If you like OCZ, buy two of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227236
They're only $94 each after a rebate. That's less than $200 for 4GB of RAM. There's several similar deals on NewEgg.

I'm thinking of getting http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=12C7FE00A5CA7304.
Is the above better or equal to the ram that Apple installs them selfs, or is the Apple RAM better? Also, does installing this void any warranties or etc. from Apple?
Searching is a good thing...

Installing RAM does not void the warranty - Apple includes DIY memory installation instructions in the manual.

There is no 'best' or 'better'... either RAM is compatible, in which case all 100% compatible RAM will perform exactly the same, or the RAM is out of spec and isn't compatible.

Most 3rd party RAM has a lifetime warranty, which is longer than Apple's 1 year warranty. But presuming that it is well built and guaranteed compatible RAM from a reputable company, there is very little to choose between brands other than your own preference.
