So far it seems that there are no utilities for W2K to set Write Combining on a supported K6 CPU.

It seems though that Microsoft fixed a bug in NT 4.0 for the K7, as seen it this article below -

AMD CPUID Check for the AMD Athlon Chip Now Allows Write-Combining Feature' ">http://support.microsoft.com/d...x?scid=kb;en-us;231949

Does WC really make a big difference under Windows, or only in a DOS mode environment? I've heard conflicting views on this.

Thoughts?

Really? WOW Charlie...I wonder who you learned that from... !!

In all seriousness...does WC help only in DOS, or also under Win32?
