The chipset is able to perform quad interleave, Tyan realized only a
twofold interleaving on its Thunder 2500 board.

I have benchmarked the i840 board (also dual PIII-800EB) myself,
obtaining a stream performance for triads of 580 MByte/s.

Yes our machine has two cpu's. The memory cofiguration is 4*256.

Running two copies of stream simultaneously, I get the following results

Function     Rate (MB/s)  RMS time   Min time  Max time
Copy:        215.2202      0.6830      0.6700      0.6900
Scale:       215.2202      0.6806      0.6700      0.6900
Add:         254.4662      0.8632      0.8500      0.8800
Triad:       248.6164      0.8796      0.8700      0.8900
Function     Rate (MB/s)  RMS time   Min time  Max time
Copy:        212.0552      0.6814      0.6800      0.6900
Scale:       212.0552      0.6926      0.6800      0.7000
Add:         251.5073      0.8760      0.8600      0.8900
Triad:       304.6427      0.8649      0.7100      0.8800

which are a little bit disappointing in my opinion,
