So my guess is that it's either:
1. Unstable overclock
2. Not enough voltage
3. You hit the limit of the chip's efficiency

Once you get past a certain point you will actually start losing performance no matter if you believe if you're stable or not at that frequency. At least this is my experience in overclocking.
Sorry those points are invalid in my case since even at stock speed with ht-on just has default i still get microstutter in metro benchmark. The only way i have not seen it is with ht off

in 5ghz club is well known that sandy bridge 2600k can reach much lower temp and voltage while disabling HT.
There is also a possibility with there being something strange with HT on this specific chip, I have no Sandy Bridge knowledge so it could be a chip flaw.

I am looking at your sig and I noticed you have 1.1v on the GPU. I am not saying we are the same, but I can't run 900 stable at 1.1v, I require a full 1.38v for true stability, no artifacting experience. I need a flat 1.213v just to get both GPUs to 960 and thats my limit. I run 850 at 1.1v, so maybe try maxing your voltage while benching for both tests.

Another thing is, this type of thread has been posted a lot (not with Sandies mind you) so look at it from our perspective, we have seen quite a bit of proof that there is little-no difference with HT on vs. off in gaming (most of the time) so this leads us to try and troubleshoot as if its a problem with settings/voltages.

my videocard is stable but if it matter like i have said before even with my videocard on default, different drivers and all the stutter still there. But can't wait to go home and do more research. If anyone has metro2033 and run the benchmark to see if they get the same perfomance gain from HT-off. It was really noticeably smoother. i have done a lot of research online and i'm not the only one who notice a smoother less stutter gameplay with HT-off. Is to early to tell but i'll have more on it tonight with more games.

Again i'm not debating that IT IS, just what i found and as of now seems to be better for me. Would like if you guys try it cause we might have something here.

HT only affects some games, and even then its so small its unnoticeable.
I like to multi-task while I game so I leave it on.

My overall system performance is much better with HT on.
If there is a game that doesn't work with it so well who cares.

More and more games are benefiting from HT as time goes on, including several now.
My benchmarks at 4.0Ghz with HT on are nearly identical and/or better then if HT is off.
BC2, Crysis, WoW, SC2, Dirt 2, NFS:Shift, GTA4, Mass Effect 2, AVP, etc... I don't currently own a game that is in anyway hindered by having HT on. Thats just me though.

Overall system performance isn't as close when its off if you really use your system like I do, although 4 cores/4 threads is still damn admirable.

If I wanted to turn if off I would have bought an i5 750 but even my 930 at 2.8Ghz beats a i5 750 at 4.0Ghz sometimes

I think it comes down to the users' individual preferences.

i just got home and tried out BC2, i did not measure FPS but playing with ht-on and ht-off there such a different i can tell that Ht off IT IS a smoother gameplay. I can actually say that right now i even feel a little motion sickness on how smooth the screen was reacting having ht-off. with HT ON i can tell that it is not HAS smooth. I returned everything to default setting video card, ram cpu at 3.4ghz and tried it, same result. Also went back to my overclock setting and still there it is not nearly has smooth. Again this is not about higher FPS it is a smoothness that is just not there when i compare the 2.

right now i'm priming my 5.2ghz HT-OFF to see if it needs a little more volt. right now prime95 blend 1 hour and still good. i'm sorry but in my case HT off win in gaming, this is my opinion base on my finding.
