Hi Everyone!  

I have 2 computers, One running Iatkos L2 updated to 10.7.4 with 6GB Ram 1066MHz NVidiad GTX 550Ti - and the other Windows 7 X64 Ultimate 5GB Ram 1066MHz. NVidia GeForce 9500GT.

Both have the same mobo (GA-X58-USB3) and CPU (intel i7 950 @ 3.06GHz)
This is pretty much a fresh install with patched DSDT.

Novabench Scores: Windows 7 Lion 10.7.4

•    System Ram Score    148       132
  
• CPU Test Score     681        328
  
• Graphics Test Score   32      316
  
• Hardware Test Score 28     25
  
• TOTAL  889   801

My main issue here is with the CPU.  I seem to be losing a least 50% of cpu performance on Lion.

Could someone please point me in the right direction as to how I could improve my CPU score on Lion.


Thank You All!

Try with this DSDT_http://bayfiles.com/...3-F4_i7_950.zip
Includes i7 950 PStates.
You also need to edit your org.chameleon.Boot.plist without GeneratePStates.
Example:

<key>CSTUsingSystemIO</key>
<string>Yes</string>
<key>DropSSDT</key>
<string>Yes</string>
<key>EnableC2State</key>
<string>Yes</string>
<key>EnableC3State</key>
<string>Yes</string>
<key>EnableC4State</key>
<string>Yes</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>GenerateCStates</key>
<string>Yes</string>
<key>SystemType</key>
<string>3</string>
<key>UseKernelCache</key>
<string>Yes</string>

Hi Funkoyote, thanks for taking the time. Did what you suggested but still not much difference.

Did you have the F4 version of your BIOS?
Maybe the problem is in your BIOS settings.
Check if All Cores, TurboMode, Hyperthreading, CStates....are enabled.

And you don't need your Kernel Flags

npci=0x3000 darkwake=0

Have you tried geekbench for comparison with diff benchmark util, or cinebench will quickly show how many cores/threads are working by how many slides it processes at the same time. For chameleon you dont need both cst using system io and generate c states both, but with proper DSDT you shouldn't need either nor the enable c3, c4, etc. make sure appleintelpowermanagement and lpc are loading, if you have nullcpupowermanagement.kext remove it.  Also curiously when i was doing some testing the other day, removing UusBusFix=Yes from boot.plist lowered scores by a couple thousand points, so maybe try adding it to yours

Hi, Thank you for your help guys!

Yep you were right Funkoyote. Different bios versions. Win 7 had F2 Bios and iAtkos had been upgraded to F4.  Somehow the F2 version(Win 7) seem to be running the cpu clock faster than the F4 version(iATKOS L2)...hmmmmm, might have to downgrade my bios back to F2 version.

Of course I did copy all bios setting exactly the same yet F2 bios CPU still clocked faster. I even swapped CPUs just for arguments sake and yet the F2 bios still clocked faster.

Now just have to downgrade bios back to F2   will post results later....cheers!!!

Oh and since I have dual boot on my Iatkos, I booted into Win 7 and had a cpu score of 390. Still no where near F2 bios version!

[Funkoyote]

F2 BIOS makes faster CPU clock than F4? That doesn't have sense.
The only important thing is configure BIOS with the correct settings.

Hi Funkoyote...Here are the results after downgrading to F2 bios...

I also upped the cpu multiplier from 23 to 24 which is the max for ga-x58-usb3 board. I also did that on F4 bio but only got up to 380 on cpu score.
Somehowo the F2 bios is way faster then F4.

[Funkoyote]

Please, take a look to this GA-EX58 and GA-X58A DSDT native power management modifica...
I believe that you are going by the wrong way.
Have you read what eep357 tells you?

I Just did a test (x64) on Geekbench and got a score of 10538 (with Nullcpupowermanagement) and 10263 (with out Nullcpupowermanagement kext)

[eep357]

That would be about right as far as slight dip in bench score with speedstep enabled vs not enabled using NullCPUPowermangement, speed step won't help performance, but it will help your electric bill a whole bunch, unless you run benchmarks 24/7. Did you add the UsbBusFix to your boot.plist? I don't need it for USB function since it's handled in my DSDT, but apparently that fix effects the entire smbus for the better. At the speeds your running right now your scores are just about where they should be tho. Gotta add a gigahurt to that to get into the 13,000 range

[Kit67]

Just did another test without NullCpuPowermanagement and I added UsbBusFix to boot.plist and got a score of 10475.
Still I'm happy just to get it over the 10,000 mark considering I was hitting the 5000 range a couple of days ago.

Thank you for your help Funkoyote and eep357.

Sweet, looks spot on where it should be with standard HD and stuff. As you bump up the BCLK the memory and GPU will follow. Most notably though you beat the snot out of you Windows scores, so congratulations to you sir!
