Hi all

Hope somebody can point me in the right direction.

I have a mac pro 2008 & use lion & ZDNet clock to overclock to 3.55Ghz.
To get it to overclock I have to start up in 32 bit, use ZDNet clock & then restart in 64 bit.

I am about to buy an Nvidia Titan & this requires Mountain Lion 10.8.4
But mountain lion does not have 32 bit mode. Any ideas?

Thanks in advance.

I thought ML would allow 32bit startup by holding the "3" and the "2" key? That's only Lion?

Not since Developer Preview 1. All 64-bit kernel since, which is why original Mac Pro is unsupported.

Try boot in 32bit Lion, set clock, then reboot in ML. Should work that same.

Unfortunately its not that simple. The nvidia card will not display under Lion & I really don't want to have to swap monitor cables each time. I was thinking there might be a windows equivalent that I can overclock the FSB & then boot ML.
