Why do you reject the quad Opteron computers (supporting 32 GB of RAM) from vendors like ASAComputers (and, no doubt, though I haven't checked from PCs for Everyone and others)? The computers, themselves, may not be from mainstream vendors, but they are from motherboard manufacturers that I'd be inclined to call mainstream -- SuperMicro, Tyan, ASUS. ~ Matt Temple | | ...as long as it costs more to equip hardware with good amounts of | memory than it costs to buy the hardware, the refinement of 64-bit | OS for access to large amounts of memory can't take off properly, | can it? | | Cheers, | | Elia | | | On 27 Feb 2005, at 15:40, Joe Landman wrote: | |> |> |> LAI Loong Fong wrote: |> |>> The process in OSX 10.3 can only see up to 4GB of ram.
