Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
And you mean that simply because you're benchmarking, those processes won't affect a CPU running HT OFF? You think that the 4 physical cores running the benchmark aren't doing anything else in the meantime?
I'm sorry to say this but you have no idea what you're talking about here.
The...
The modified batch file assigns one thread to each of the physical cores, ergo, its exactly the same as running HT on as HT off, and my results proove that.
Why can't you understand anything I've written so far?
Like I said earlier, the 0,3% difference (40000 size) could be attributed to the different ways I overclocked the processor or even to different processes being run in the background.
Are you even reading what I've written?
Edit: For instance, while doing the HT test I had Asus AI Suite on...
I don't think you understand what I did with the batch file.
Here is with HT ON:
Performance Summary (GFlops)

It's easier to go into bios, turn HT off, run benchmark, reboot into bios and enable HT compared to just changing the contents of the batch file (which takes a couple of seconds)?
I bought an i7 to get HT, not so I could turn it off to save a few watts :)
You get better result running 4 threads, even on quadcores running HT. The thing I did earlier was assigning the threads to the physical cores, if not doing that then the first 4 cores (2 physical and 2 "HT"-cores) would get assigned and performance would be bad.
Why not modify the batch...
If you want to run it properly on a 4 core cpu with HT enabled then change the contents of "runme_xeon64.bat" to the following:
@echo off
SETLOCAL
rem Setting up affinity for better threading performance
set KMP_AFFINITY=nowarnings,compact,granularity=fine
rem Setting path to OpenMP library...
1920x1080@75Hz is possible over DVI (Displayport also, haven't tried VGA).
I uploaded the .inf here: http://data.fuskbugg.se/skalman01/u2311h.inf
Credit goes to ToastyX for providing the timing information. I tried to get 83Hz working over Displayport, didn't work though.
