I think you have an antique there, it's older than some of the junk in our server room.
The particular cpu in your link is a 32 bit one, but:
This list, with bios 16.0, includes 64bit cpus. (M0 stepping stuff near the top.)
So, if you only have the cpus you had a link to, then you won't be getting any 64bit action.
Hope that helps in your quest for massive process space.
You may be better off retiring that power hungry monster and playing with something newer, even the lowly atom boards
that come with packets of cereal are 64-bit capable these days.
Thanks, bunny, for your assistance! This thing is at least 8 years old, but it didn't cost a lot. I figured it would be a good learning platform, though I've ended up spending more money than I'd originally planned to. The power consumption issue is something that I've been thinking about--that and a quieter setup. I'm going to keep my eyes open and see what I can find in a lower-cost board with quad core support that also offers dual Gbit LAN ports. Then I'll have to find a server case that'll handle at least 8 drives...
Well, there you have it, the official answer from an Intel being, which means that the documentation is seriously confusing if we have to call on the creator for the definitive word.
If you put an 800Mhz FSB cpu in, would it run at 533 and give you a rather sedate 64-bit system?
I guess the only other way to use all that lovely extra memory would be the dreaded PAE kernel.
Personally, I think a more modern board would blow the socks off this and eat fewer electrons too.
No the SE7501WV2 board does NOT support 64-bit, or more specificly, Intel-64 or formerly known as EM64T. The board does support Xeon processors with 533MHz FSB, but these CPUs are not 64-bit capable. I don't think the Xeon processors with 800Mhz FSB (which support 64-bit) will work on this board.
