I'm pretty new to this, so take it easy on me!

I have an HP xw8600 running 10.7.2 with the following:

no DSDT edits
2x x5450 Xeon
4gb RAM
Nvidia Quadro FX 1700

My question/problem..

With NullCPUPwm - My geekbench scores are kind of low - 8257, but idle temps are also low, at about 113f-117f (via iStat, and down to 111 as I type this). I also noticed that the CPU voltage always remains constant at 1.04v with NullCPUPwm installed.

Without NullCPUPwm - My geekbench scores are, in my opinion, awesome! - 11612 (destroying my 2010 17" i5 MBP 8gb RAM), but my idle temps are high (I think?) at about 126f - 129f and up to 140ish under load. But, the CPU voltage changes, so I guess speedstep must be working in some capacity without NullCPUPwm, going between 1.04v and 1.12v depending on load.

Its probably worth adding - I get this in my kernel log when booting without NullCPUPwm.

Code:
localhost kernel[0]: AppleACPICPU: ProcessorId=1 LocalApicId=0 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=2 LocalApicId=4 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=3 LocalApicId=2 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=4 LocalApicId=6 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=5 LocalApicId=1 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=6 LocalApicId=5 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=7 LocalApicId=3 Enabled
localhost kernel[0]: AppleACPICPU: ProcessorId=8 LocalApicId=7 Enabled
localhost kernel[0]: ACPI: System State [S0 S3 S4 S5] (S3)
localhost kernel[0]: ** AppleSMBusPCI::start failed to get acpi path for provider
localhost kernel[0]: ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed
localhost kernel[0]: ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed
localhost kernel[0]: ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized

I do have generate p and c states set in the boot plist too.

My question is, how can I get the best of both worlds here? Or am I worried about nothing in regard to temperature? I've researched a ton, but am having a hard time understanding everything.. tjmax, tcase temp etc..

I tried every method I could find for extracting DSDT's and SSDT tables, in Windows, Linux and OS X, and no matter what, there is no DSDT Scope (_PR) anywhere.. So I am at a loss.

Because I am pretty new to this, I am not sure what additional information I can provide to help you guys help me.. So please ask, and I will post whatever is needed.

Any help would be greatly appreciated! I wouldn't have made it this far without this awesome community!

Thanks!

Also forgot to mention a few observations about sleep..

Without NullCPUPwm, sleep works fine with the power button without SleepEnabler.

With NullCPUPwm, sleep only works with SleepEnabler (Will sleep w/o it, but won't wake)

In both cases, it will only sleep manually, i.e. sleep settings in system prefs do nothing. This doesn't bother me at all, however.

Thanks for the help!
 
Does the onboard NICs work on your system or did you use an external NIC?:?:
