Hi Steve, what am do you recommend for 9900k with ht on?

5460 Good? or is there better?

I would try AM340 any four cores first. Adding a fifth or sixth may be worthwhile so give it a try. It depends on the system. Corral addon exe's into the unused cores a minimum of 2 LPs per exe.

5460 using six cores six LPs is a good idea.

Copy that, thank you

Tried 4,5 and 6 LPs. 6 feels best in loading and quickness, and smoothness.

Thank you.

This is in line with my experience, although my 8700K does not offer more cores. Best results I get with AM=1365, enabling all LPs on my six core HT CPU.

Those who turn off HT due to heat, I have two questions that always bother me:

1. why the heck you buy a more expensive CPU with HT but then turn it off? If you do not want HT for anything, buy the 9700K...

2. why the heck do you think that 100-200MHz more makes a difference? I mean, running the CPU with HT off on 5.1GHz while with HT on "only" 5.0GHz (or 4.9GHz) would be possible, is just... well, ridiculous? Those 100-200MHz are 2-4% clock rate difference, even if 100% of this clock difference would be transformed into performance in P3D, it would mean: 26 instead of 25FPS, 52 instead of 50FPS. Or in other words: nothing ;-)

Verdict: for the sake of a fluent and properly running sim, turning off HT simply does not make sense. Not at all. You gain nothing but you loose probably pretty much.
