I guess becuase the AMD64 is native bigmem, while the x86 you gotta work at it.

Post #160,672 by folkert 6/20/04 8:28:45 PM Reply	I believe it will see the 8GB When you put in the other two Procs. Many of the things I have read... say that there are 2 memory buses. If you have 2 Processor each bus is supported by one of the procs. If you have a board for 4 procs, you need the 4 procs to see all the memory as they are on the other bank. Now I have read that the 8 proc boards are similar, but are going to have 4 memory buses, 2 procs per bus. And are needed to see that memory... But, I have also heard of CPU slots terminators for Intel Stuff, I wonder if that would apply for AMD stuff. -- [link\|mailto:greg@gregfolkert.net\|greg], [link\|http://www.iwethey.org/ed_curry\|REMEMBER ED CURRY!] @ *i_wethey* Heard near the SCOG employee entry/exit way: `Security: We got another Mass Exodus Doorway Jam.`
Post #160,691 by broomberg 6/20/04 10:02:28 PM Reply	Don't think so Each CPU board has slots for memory. The rule is that you can only have one type of memory on each CPU/board. But you can interleave memory across multiple CPU boards. So you must have all identical memory on all boards, which it why we tossed the initial 2GB (512MB chips), leaving 4 in big chips.
