I am using a 2 x 2.3Ghz PowerMac. I have seen some 4GB RAM sticks on ebay that will fit into the ram slots, but they are listed as 'Mac server ram'. Will this RAM work ok in my machine? I am a music producer and CAD designer and work the computer quite hard on occasion so I didn't want to mince around buying 1GB sticks, but to buy the highest I could to slowly fill up the 8 slots available. Below is the link to the ram I am looking to buy so long as it's suitable. http://www.ebay.co.uk/itm/230959196983?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Maybe someone has some advice on what is the maximum ram available for my mac or the best solution for me? Thanks a lot, Dan.
