You should get Fastvid. It's a DOS utility that configures some P6 chipset options to vastly improve PCI performance. In other words you are probably bus bottlenecked right now.

A P2OD 333 is vastly faster than a P166. If you need proof get a Voodoo3 and try playing Unreal on both systems. 😀 Unfortunately SMP does jack for old games though.

You could get AIDA64. The benchmarks on there are SMP aware and contain optimizations for different processors. Your setup should outperform a P166 by far in those.

I'll give Fastvid a shot. Not really playing games with this setup, mostly web browsing under WinNT. Opera 10 works pretty good. I tried Aida64, and it scored in line with what it should have -- like 2 points below a regular dual Pentium II 333. I'm good with that. Not sure why 3dbench scored it so low...thanks for the advice.

I think in NT the video drivers will take care of what Fastvid does in DOS. Maybe not all video drivers though.

You can also check the BIOS for options like USWC (uncacheable speculative write combining) and write posting . They can cause instability however.

Actually I would expect a PII Overdrive to outperform a PII at the same clock speed and FSB due to fullspeed L2 cache. However, they used an LX system with SDRAM, so that may explain why yours still benchmarks slower.
