Via Apollo Pro 133

I have got the computer with the Via Apollo Pro 133 chipset. My CPU is
Pentium III 1000@1050 Mhz. My motherboard is Shuttle AV11. I have got 384 Mb
of PC133@140 SDRAM Memory. My graphics card is Geforce 3 Ti 200. I installed
4-way Memory Interleave Enabler. Is my computer much slower than similar
configuration on BX chipset? In Sisoft Sandra 2003 memory benchmark shows
about 1000 Mb/s (fpu and alu tests). Everest shows the read from memory
about 1070 Mb/s and write about 200 Mb/s. I have got the short memory access
time in Everest (103.1 ns). This is similar to DDR memory. If I insert the
memory chip to the first socket in the motherboard the PC133 Memory have got
the erros eg. Stop errors in Windows XP. What way can I also tweak my
computer? Is 7000 3DMark good result on my configuration?
