Hehe, nice story! (BTW, 12-24 hrs of battery power? )

There may be something you've shed some light on...it's possible that I've made my dumps with clocks on 8.5x400 instead of the currently used 9x333...I'll redo the dumps tomorrow.
About p-states: it's really strange. In VoodooMonitor I get 4 for the multipliers across 6-9 (with voltages, of course), but Windows uses only 2, 6 and 9. And +1 question: so if p-states appear in VoodooMonitor without DSDT patching it cannot be considered working yet? (It did the multiplier switching without patching, but not voltage changing, because of the missing _CST. Ah, and one more: when I've seen the mult. switching (9 to 6 and 6 to 9 like in Windows) NullCPUPM was loaded, so as SleepEnabler, so AICPUPM wasn't running. Now that's strange! Or I'm stupid and missing something?)

But let's leave it for tomorrow, I'm tired now, was a hard week at school. Thanks again!

Oh yeah. Like I said: FakeSMS sucks (it's far to limited). And please share what you did with the rest of the peeps here. I tell you this: Experimenting is good – and you showed it – even if it makes your head spin!

p.s. There's a small hit yes, but who cares if you care about these values.

I'm sure I didn't do it the proper way and it's off topic here, but you asked, so it's here

If you have time please take a look, maybe you can help me to do it right.
Thanks.

What Beerke'ed said. And the reason for this is simple; text files are known to add invisible characters, making it impossible to compile without fixing the errors first. Now help others to help you. Start by attaching a correctly formatted ZIP file and who know what might happen tonight

Light bulb: I am going to help some of you GB users. Not here of course, so feel free to open a new topic and let's get cracking. A one time only offer of course!

Master Chief, I'm a total noab when it comes to DSDT editing and didn't realise about uploading in txt. As per your suggestions I've opened a new topic for Gigabyte users and who wouldn't want to take up the offer from Master Chief

LOL I just got a PM from Keeza about this. I guess that I have to fix PC insomnia and as a result.. I can't go to bed anymore. Oh well. Here we go!!!

Edit: Part I is all about the USB devices and is Done!

Yes sir. Mainly to compile the Mozilla (currently compiling Firefox 3.6) code base (24/365) which takes about five minutes per product, and that's when I join you guys

My twin 30" monitors are the bad guys here (still waiting for Apple to produce new LED replacements, which I think should be available any time soon now) but with LED lighting and a single monitor I can keep working around the clock (that's when the the generator kicks in). Well the hardware can because I am going to have some other fun now

[Matthew L.]

I've uploaded my new SSDT tables (correct frequencies should appear now), and the DSDT table with the appended SSDT loading code. Well, it doesn't work, I'm getting _CST errors at boot with it. Can you please check it?

EDIT: FYI, I've acquired the loading address from Everest in windows of course, it's always at the same address, isn't it?

Righty Hoe!

I've got as far as changing the P and C state parts as per MC's v2.8.

Please note I edited and checked that it compiles on XP (Quite day at work!) - I have NOT tested this yet !

Chief can you please have a wee look for me - see what you think?

**EDIT** this is in vein and last ditch attempt to get C-states working !

I stopped at the SMBUS changes .... I'm saving this for another day

[Master Chief]

I've uploaded my new SSDT tables (correct frequencies should appear now), and the DSDT table with the appended SSDT loading code. Well, it doesn't work, I'm getting _CST errors at boot with it. Can you please check it?

Done. See attachments.

[h.M.M]

I just finnished extracting the SSDT in linux (Using this) which gave me 5 .aml relating SSDT.
But I couldn't make any sense of the linux howto. :/
So if someone could point me in the right direction it would be much appreciated.

PS. added the SSDT from my Q6600 if someone need it.

Done. See attachments.

Thank You, Sir! I owe you much! I had to add a Name (TYPE, 0x80000000) (renamed later) and calculate my P-States (P-state calc gives the same values to status as control values, should I use 0-1-2-3 instead, like in the dsdt you've supplied?), but it's working! (Later added LPC dev-id patch too while searching for a solution to higher temps.) Thank You, it's just made my day!

I have two one questions left: my temps are a tad higher than before, so AppleIntelCPUPM makes my cores run a bit hotter, is there any fix for this? Corrected it by renaming TYPE to PDC0. And the second one: even in idle, by the time of writing this post and listening to some MP3 music through iTunes my pstates change from the lowest to the 2nd lowest frequently, is it normal, or how can I change some parameters of moving 1 state higher?

Dsdt.dsl attached for reference.
Edited, added some comments.
Edited once more, commented custom P-states to avoid disaster among the people willing to try this.

Righty Hoe!

I've got as far as changing the P and C state parts as per MC's v2.8.

Please note I edited and checked that it compiles on XP (Quite day at work!) - I have NOT tested this yet !

Chief can you please have a wee look for me - see what you think?

**EDIT** this is in vein and last ditch attempt to get C-states working !

I stopped at the SMBUS changes .... I'm saving this for another day

I don't seem to have gained anything from this.
CPU temps are the same - I still don't enter a C states lower(higher- whatever) than 0.
P-states remain the same.

I tried changing CFDG to 0x40383E2 to no avail.

I'm going to try MP3,1 cst values but I don't hold much hope.

Maybe check my DSDT.dsl, take a peek at the differences, make some changes, specifically in P-states and location and length of the CpuPm SSDT table. It's been made by Master Chief, and His suggestions. (Important things are at top.)

My P-states work just fine - always have

I have no native cst (c-state) SSDT tables with my MB and c-states is what I've never managed to get working - I'm just trying all possiblilites ATM.

Your DSDT doesn't contain a CPUpm table - it contains your PSS table and data and cst tables from a MacPro3,1 with modified bit width, bit offset and address values.
If you look this is the same as mine - as that's what I've just copied from MC.

I've never got a _CST table from my motherboard too (only Cpu0Ist, Cpu1Ist and CpuPm), and it loads the CpuPm table from it's address by a code, which Master Chief suggested and writed, so if they are the same, why does mine work and yours doesn't? (No offense, just real curiousity.) And my P-states were working too, 'till the _CST errors were eliminated at boot: at this time, the multiplier stuck, so I had to append my p-states, even if it was working before without patching. AFAIK, my X48 board is more identical to the series 3 MoBos than the series 4 ones, and it's a Gigabyte, too.

I get working sleep, CST, and PST (voltage and multiplier autoswitching by AICPUPM kext), and normal temperatures (30/34C in idle) with this DSDT.

Did you extract your SSDT tables in linux?

do you have a C-state option in BIOS - other than C1E ??

Name (SSDT, Package (0x18)        {            "CPU0IST ",             [color="#ff0000"]0xDFEE7F00,             0x022A, [/color]            "CPU1IST ",             0xDFEE83C0,             0x0152,             "CPU0CST ",             Zero,             0xF000E816,             "CPU1CST ",             Zero,             0xF000E816,             "CPU2IST ",             0xDFEE8520,             0x0152,             "CPU3IST ",             0xDFEE8680,             0x0152,             "CPU2CST ",             Zero,             0xF000E816,             "CPU3CST ",             Zero,             0xF000E816

I've extracted my tables in Windows with Everest, and I don't have any other options than enabling or disabling C1E, and the address is not the IST table's address, but the whole CpuPm SSDT table's address (and length).

Very interesting - Ill give it a go (later toninght - @work ATM.). If it works I believe I'd owe you and MC a pint !

Did you extract your SSDT tables in linux?

do you have a C-state option in BIOS - other than C1E ??

##EDIT## you can see in the above table my cst memory address is zero !! what adress value does your similar table show?

FKA, take a quick peek at this post. It offers an interesting cause of c-state problems with X58 Gigabyte boards but perhaps this is a board wide problem with all GB MOBOs.

You don't owe me anything (if it works of course), everything goes to Master Chief, the source of all great ideas!

FYI, C-states didn't work with my Asus P5N-D (nForce 750i) motherboard (nor with the current X48 GB board) with the same CPU if I didn't use the default voltage (in windows of course), and IMO this is the case with all the motherboards from the Core 2 era (or even more).

Also very interesting kdawg -

Thanks both for the food for thought !
