Hey guys longtime reader first time poster, 100% mac convert now. Anyways i've read the few threads about the Alu MB DD3 ram upgrade freezing issues, as i have first hand experienced this with a set of Crucial DD3 from newegg, however i purchased the set that was not under the "Apple" category. Has anyone had any luck with the Crucial Apple set? this was the set that i purchased http://www.newegg.com/Product/Product.aspx?Item=N82E16820148191 i have recently purchased this OEM samsung set which should 100% since our notebooks came with samsung, at least mine did anyway http://www.18004memory.com/focus.asp?sku=502874&guid=67E58D5E2DE6441E93A38C2D0467ED6F i know it says MBP but it should be the same and the same set for MB costs $165!! http://www.18004memory.com/focus.asp?sku=502866&guid=67E58D5E2DE6441E93A38C2D0467ED6F anyways i hope this set will resolve any further lockups otherwise ill just spend the extra money and go to the apple store.
