    Excellent upgrade

    My older Macpro died, bought a better one but needed RAM upgrading. I have purchased from MacSales before with very good results. My computer runs excellent now thanks to a cheaper alternative in purchasing the RAM from you. MAcPro is much much faster enabling it to meet my workflow now. Very good quality, never had a problem with products from MacSales.

    I would recommend this product to a friend!

    4GB modules

    had not realized how expensive these had been...now perfectly reasonable...went from 6 to 10...great horsepower leap for mac pro early 2008 install went well...one might note that for this version of mac, modules only insert in *one* direction overall, great product and install help from OWC

    Worked Great

    OWC's memory boards works just like their supposed to, and works a long time. I've never had a problem with any of OWC's Memory. I recommend, however that you use OWC's support system to make a correct choice. I didn't a couple of time and regretted it.

    I would recommend this product to a friend!
