UNSOLVED
M18x CPU benchmark problem
I have just bought my M18x (manufacturer refurbished) with this configuration
i7 2820 QM 2.3 ghz with turbo boost to 3.4ghz
16 GB ram 1333mhz
ge force gtx 460
etc...
On the windows experience index benchmark and specifically on the processor test (calculations per second) i always get a 4.6 score while on all the other test i get 7.0 and above.
Now my alienware system came with windows 7 Professional (64 bit), i reinstalled it and still got the same results. I now just installed windows 7 ultimate and still get the exact same benchmark.
I have tried benchmarking with programs like passmark (performance test 64 bit) and still i get lower results than my previous laptop which toshiba qosmio 1 st generation i7.
What do you suggest ?

make sure you dont have your processor throttled by a certain power state. Make sure your in high performance or w.e. and go into the battery settings make sure the processor is forced to 100%

the processor is forced to 100% and its in maximum performance.
Intels processor identification utility states that its a 0.79 GHZ i7 instead of a 2.3 GHZ

If you disconnect the AC adapter and operate the notebook on battery power only, the system defaults to the minimum processor frequency. You cannot overclock on battery power alone. You should not rely on the retail Intel application to look at our OEM (original equipment manufacturer) CPUs. Even programs like CPU-Z are misreporting items. On the first Bios screen, how is the CPU listed?
* The AC adapter must to be connected to the system
* In the operating system, the power plan under power options has to be set to "High performance"
* Restart the system and hit F2 on the Dell logo screen to enter BIOS
* Go to the "Performance Options" menu under the Advanced tab
* Set Overclocking option to "Enable"
* Set "Level 1-3 Overclocking" as "Disable"
* Press F10 to Save and Exit

System is on AC
Bios as also Intel Processor Identification Utility identifies i7-2960XM Extreme @ 2.7 GHz
But the Intel-Tool shows the estimated CPU-speed @ 2.70 Ghz and the actual speed @ 0.79 Ghz.
(Same in Tools like CPU-Z)
Windows 7 Ultimate performance Monitor now gets 4.6 Points for CPU (even futher there has been 7.6 Points...I have Screenshot from both)
Is there anyting damaged?

So you was sold a i7 2820 QM, which shows as a i7 2960XM ?
Try HWINFO, this reports the correct over clock on my 2960.
790mhz is the lowest speed which is where the machine idles, but hwinfo shows it go up in readtime as you do things.

fireheadAR,
All three applications, HWINFO64, CPU-Z64, and the Intel Processor Identification Utility are reporting the correct data for my M18x. It really sounds like the Bios Overclocking settings are wrong on your systems. You all need to post exactly what you have chosen in the Bios.

I have just run on my m18x Intel's Processor Identification Utility
Reported CPU Speed 0.79 ghz
Expected CPU Speed 2.3 ghz
There is obviously something wrong with my CPU is there a software tweak though for a solution to this problem ?
Or should i send it back to DELL
