Didn't Win98SE have issues with clock speeds north of 2GHz? I seem to remember reading something about that on here once before. I have a Northwood core 2.4 GHz P4 machine I'm going to flip to Win98SE when we move and I get it out of storage. It's always been stuck in my head that I'm going to have to put it's original 2.0GHz processor back into it in order to get it to run properly.

There is no limitation of speed for Windows 98SE, however pentium 4 HT (Hyper Threading function) needs to be disabled in system BIOS.

Don't even need to do this, I tested with my Prescott SL7PP and was no real world difference with HT enabled or disabled

Its just recommended in the wild 😀
I also remember comments about the large Prescott pipeline not being optimal support for legacy purposes.
However I wouldn't say don't use it and given its one of the fastest its probably a geeky unoticeable until deeply probed thing.

may not make a difference, but may save some power/heat by not having the extra thread on
