Does anyone know if the Triton II chip sets (430HX PCIset and 430VX
chip set) cache more than the "Lower 64MB" of memory, which is what the
Triton (430FX PCIset) caches.

I found out about this when I found my Pentium 166MHz system
ran slower with 128MBs than with 64MBs, 22 versus 37 on Norton
Utility's System Information benchmark.  After having the retailer
check all of the EPROM settings, we called the motherboard vendor
(Tyan for Titan III motherboard) and found out that the Triton
chip set only cached "the first" 64MB of RAM.

I found a web site that had the complete documentation on-line
(which www.intel.com doesn't seem to have: its down now so I
 can't check again.)

Page 22 of the documentation revealed that only the "lower" 64MB
of memory was cached.  There was no earlier direct reference to the
fact (I suppose that counting bits in registers would have made it
clear), although there were many references to supporting caching
of various types and 128MB of memory.

I can't find the Triton II complete spec sheet, so does anyone know
how much memory is elegible for caching in  430HX and 430VX PCIset's?

Thanks.

(I but "lower" and "first" in quotes above since I don't know where
 the memory for the Norton benchmenk is allocated.  I would have
 assumed that the memory would be within the first 64MB of memory on
 a system with nothing but Windows 95 and the Norton test running, but
 it might work just the opposite.  Having more than 64MB is not
 supposed to turn off caching - it still should remain active for some
 64MB of memory, so if the memory allocation policy was the opposite
 to what it is, the benchmark should have shown no difference between
 performance with 64MB and 128MB.)
