Solve : Speedstep vs Hyper-Threading?

1.	Solve : Speedstep vs Hyper-Threading?
Answer» Hey guys, I've been looking for hyper-threading in my BIOS. I don't have the most normal BIOS out there, so it's hard to find any instructions online as to where to locate it and how to disable it. After fully reviewing every possible crevice in my BIOS the only thing I found that somewhat resembled hyper-threading is something called Speedstep. The description of it sounds pretty similar to hyper-threading. Does anyone here know anything in particular about these two things? Thanks a bunchMy BIOS is an American Megatrends Inc. 9/04/2016Why not just specify core affinity and avoid trying to shut down hyperthreading. If your running a program that a CPU with hyperthreading is a problem, I'd just specify core affinity to core 0. I had to do this with my game Unreal Tournament 99 as for it acts up on multiple core CPUs for a game written back when single-core Pentium III's were the gaming rig processors. On a CPU with hyperthreading the 0,2,4,6 cores are physical and 1,3,5,7 would be the hyperthreaded. So if looking to avoid running on the hyperthreaded core then avoid those with core affinity set to 0,2,4, or 6What are the motherboard and CPU? We need this information. Speedstep and hyperthreading are totally different things. Quote from: Salmon Trout on September 28, 2017, 02:05:14 AM What are the motherboard and CPU? We need this information.

The only thing I can find that matches what you're referring to in my BIOS version is that it says I have a 4 core processor and I can choose how many are active; all, 3, 2, or 1. Would what you're saying be setting it to 2? Thanks Core affinity is set within the operating system, using Windows Task Manager for example, or via the Start command.

Oh my goodness, I'm such a noob. Haha. That makes perfect sense now. Thanks man!No Problem & Thanks BC for stepping in and pointing them to the OS vs BIOS. I posted last night HALF awake and totally forgot to tell where to set this. So far it's been working! No crashes yet. I didn't set the affinity to zero, I just put the priority level up to realtime. I haven't had a CRASH at all. Usually it crashed when big explosions happen or vehicle collisions, and I've been in some crazy situations where it would have for sure crashed but it didn't Cool! Which game?
