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.
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!
