RE: Which 21264 already supported?

[Tom Morris <Tom Morris alpha-processor com>]

The 264DP may be stable, from my experience running benchmarks, the 
API UP2000 is considerably faster since it's available in a dual 667 MHz 
configuration vs 500 MHz 264DP or DS20.  It's also got on-board Ultra2 SCSI 
in place of the UW SCSI on the 264DP and uses standard 168 pin DIMMs
instead of the more expensive 200 pin DIMM used in the 264DP.

If the goal is to have the most powerful system that'll run Linux, I'd go 
with the UP2000.  I'm biased, but it doesn't change the facts!
