Intel 4.5GHz & 5GHz LinX Stable Club

If you can explain how a 5Ghz hexcore performs the same as my 4.1Ghz quadcore!!!

You answer is probably below:

Man, HT is off on this mean more GFlops.
I think you know this.....

[addressing to Ivanqu]
What version of Linpack library do you use fot the test?
Try download and run LinX it from 1st page of the topic-download included updated Linpack library by Intel whick fixed some GFlops issues.

It might be in conjunction with some other BIOS settings, which I'll try to investigate/replicate. Well, not at 5GHz.

Well, I tried to replicate low GFLOPS issue, but failed. No matter how I tried, didn't manage to get so low.
-running at 4700MHz HT OFF produced 101 GFLOPS
-disabling all CPU features dropped GFLOPS to 99
-using old LinX (linpack) dropped to 90 GFLOPS
-now with HT ON it should drop another 10-12 GFLOPS, didn't actually run, but comparing to my previous experience and observed results here.
-so, it comes down to 78-80 GFLOPS.
Only thing I know to kill GFLOPS totally is dropping RAM/UnCore to something like 1066/1600.

So, IDK


BTW, I did run full 20 loops at 4.7GHz
