Hi all i have recently got a new 2009 quad core mac pro which has 3gb of ram which i want to upgrade to 12gb.

From the likes of kingston and crucial they are charging over £900 compared with £350 from owc in the usa. Can anyone recommend anyone cheaper in the uk ? can i just get some crosair 1066 ram from ocuk ?

The Mac Pro takes unbuffered ECC DDR3 Ram, so you can't just take some normal Corsair RAM and stick it in.

Needs the ECC as is a Xeon W3520 chip not a Core i7 in the Mac Pro.

People have used non ECC normal memory with success on the Mac Rumors forums.

So three 4Gb DDR3 Non-ECC should work fine, but just disables ECC.

How would I do that and will effect performance ?
