Hey guys I have a Macbook black from 2008. Here are all the identifiers: MB404LL/A macbook4,1 a1181 It's 2.4 GHz Intel Core 2 duo and the current memory is 2 GB 667 MHz DDR2 SDRAM. I'm wondering if upgrading the ram to 4GB or even 6GB is worth it. I know apple "officially" says the model only supports 4GB, but third parties have had success with 6GB. The only drawback is possible interleaving but any performance hit caused by this is negligible. (http://www.pbcentral.com/news/viewnews.cgi?id=EkkyVApFFuIDwuIbac) Is it worth going from 4 GB to a mismatched 6GB? I've been looking around on newegg and I can get 2x2GB stick or ram for around $70. Can I buy any of these as long as they're 200 pin and DDR2-667? Is there any difference in the brands, as in some I should look for or stay away from? Any other places I should be looking besides newegg and can you guys suggest some 4GB sticks (all the ones on newegg are ddr3). Here is the page with the ram I was looking at: http://www.newegg.com/Product/Produ...=2010170551+1327924738&Tpk=macbook+ram&Page=2 Thanks in advance.
