[QUOTE="northrnchimp, post: 1066250, member: 161643"] However, snow leopard defaults into 32 bit at boot, so you will definitely see benefits from booting into 64 bit mode (as long as any third party peripherals have 64 bit drivers, if not, just boot back into 32 bit by default). Although apps can run in 64 bit, the kernel is still running in 32, so booting to 64 will give you increased security, and a slight speed boost too (about 5 or 6%) - largely because (as mentioned in the linked articles above) the 64 bit register allows 'doubling up' of operations with smaller address space. Benchmarks by [URL="http://macperformanceguide.com/SnowLeopard-Performance.html"]macperformanceguide.com[/URL] clearly demonstrate this ~6% speed boost. Just hold down the 6 and 4 keys until the apple logo appears when you boot. [/QUOTE]
