Have you really tested or just some impression?

I have AUSU Tx97-E + 64MB SIMM + 64MB SDRam DIMM. Everything works well.
It is faster than just using 64 SIMM when working with 120 processes to
use more than 90MB user memory + 10MB system memory.

HX chipset can cache more, but does not support AMD CPU :-)
