hawkin90 Posted October 2, 2011 Posted October 2, 2011 Just a question for all you fellow overclockers. Do any of you have hyperthreading enabled? And do you use speedstep? For me, after disabling HT and enabling SS my idle temps went down 7-8 degrees. I haven't really noticed any difference in performance, actually my fps went up a little in games without HT. I thought I was using SS all the time but then I realized I had to enable C1E in my bios to get it to work. Any opinions on this?

I use HT all the time , whats the use of having an 8 thread i7 and not enable all the threads (especially true for 32nm i7's since the temps are so low anyway) ? I used SS for most of overclocking and only noticed increased temps with it disabled when idling yet I can still overclock stably Share this post Link to post Share on other sites More sharing options...
hawkin90 Posted October 2, 2011 Posted October 2, 2011 Hmmm. Ok. I just wonder if HT matters for gaming. I could see it matter more for editing software and that kinda stuff. And aren't those 4 threads only virtual? Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted October 2, 2011 Posted October 2, 2011 HT isn't supported in any games that I'm aware of. In some benchmarks with multithreaded-enabled games, it even hinders performance slightly (unnoticeable in the 1-2 FPS range). There's just a small number of people that have HT'd CPU's, and to optimize a game to support HT would just take too long, and for the small amount of people that have it, it's not worth it for a 1-4 FPS possible increase. If you want to trade my i5-2500K for your i7-2600K, let me know. Share this post Link to post Share on other sites More sharing options...
SpeedCrazy Posted October 3, 2011 Posted October 3, 2011 I use HT but not SS. Share this post Link to post Share on other sites More sharing options...
Hyper Posted October 6, 2011 Posted October 6, 2011 I belive I have both enabled (HT for sure). Though I tend to run a lot of stuff while gaming Share this post Link to post Share on other sites More sharing options...
Waco Posted October 6, 2011 Posted October 6, 2011 I use HT but not SS. Why in the world would you disable SpeedStep? Share this post Link to post Share on other sites More sharing options...
MJCRO Posted October 6, 2011 Posted October 6, 2011 There's a difference between OC'ing Sandy Bridge and 1st Gen. i7's Nehalem's. You have to enable SS on Sandy Bridge to get and OC higher than 4.5Ghz with HT on. But I've know a few people that run their i7 9xx's w/ SS off @ 4Ghz+.

I ran my 5Ghz 2600k with HT using SS for months w/o problems It helps a lot with keeping temps down and thus helping keep the temp of the water in the loop cooler Share this post Link to post Share on other sites More sharing options...

I read it wrong the first time too. Share this post Link to post Share on other sites More sharing options...
SpeedCrazy Posted October 7, 2011 Posted October 7, 2011 I disabled it because my system was unstable. When it was on it would jump up under load like it was supposed to but i dont think it had enough voltage because once it jumped it tended to freeze. So i disabled it and i dont have that problem anymore. Share this post Link to post Share on other sites More sharing options...
