Wrong CPU speed after clean install and Multibeast treatment

[orde]

The information I get in the system profiler doesn't match my system (check signature).
I did a clean install, update to 10.6.2 and ran multibeast with easy mode for 10.6.2 plus selected the DSDT for my motherboard.
Shouldn't the CPU speed be 2.8 Ghz? Geekbench reports the same: 2.0 Ghz.
Is this value maybe hard-coded somewhere ?
My geekbench score is around 5700.

Did you set your Bios to Optimized Defaults? If you recently flashed the bios and didn't do this, the CPU may be stuck on a low Busratio- try that and report back.

Yup I just checked my Windows setup and it was also showing 2.0 Ghz which meant it wasn't OSX specific, so I checked the bios afterwards and sure enough it was set to 2.0 (x15) multiplier. I guess I never noticed that after flashing my bios it was dropped down to this value.
Geekbench ?! I should have been running Idiotbench, my scores would have been off the charts.
Set to 21 again now and all is normal I guess with score ~8000

With an i7 860 and 8GB DDR3 I see only 4 cores reported:

Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.80 GHz
Number Of Processors: 1
Total Number Of Cores: 4
L2 Cache (per core): 256 KB
L3 Cache: 8 MB
Memory: 8 GB
Bus Speed: 533 MHz
Boot ROM Version: MP31.00C1.B00

When i boot in Win 7 everything looks OK

Is there a fix for that? I thought I applied all the appropriate MultiBeast fixes.

You can't really go by System Profiler- as the smbios.plist has injected values. By 10.6.3, we should get i5/i7 to show up properly. Right now Apple's iMacs have a special OS X build, probably 4kb of code or less, that allows the OS to id the new Nehalem CPUS. It's purely cosmetic- doesn't affect your performance at all. See what Geekbench reports on your system.

You do know that your CPU only has four cores, right? The other four are virtual cores. I dunno how OS X reports on that though.

Tony,
Are you always online?!? Amazing.

Geekbench reports 4 cores as well:

Operating System Mac OS X 10.6.2 (Build 10C540)
Model Hackintosh Motherboard Apple Computer, Inc. Mac-F2268DAE x.x
Processor Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz
Processor ID GenuineIntel Family 6 Model 30 Stepping 5
Processors 1 Threads 8
Cores 4 Memory 8.00 GB 1065 MHz DDR3
Processor Frequency 2.80 GHz Bus Frequency 532 MHz
L1 Instruction Cache 32.0 KB L1 Data Cache 32.0 KB
L2 Cache 256 KB L3 Cache 8.00 MB
BIOS Apple Inc. MP31.88Z.00C1.B00.0802091544

Geekbench score = 8999 No idea what that means though

I have a mobile...

That means that it's plenty fast

Yeah, you are right. Just checked in Win 7 and it reports a lower Geekbench score: 8750 and still four cores.

Thanks!
