MSRDumper

[iStigPL]

Just did few test on 10.6.8 and 10.7.1 (MSI Z68MA-ED55 + i7-2600K) AMI UEFI

 

Using Chameleon without DSDT - only FakeSMC and SMBIOS iMac12,2

 

I have on my MB CPU Phase LED (6 phase power mode) - will include how they behave

 

10.6.8:

 

1. nullCPU.... 16,34 - all leds on - geekbench ~12300

2. patched AICPUPM (w/o plist) - 16,34 - leds changing - geekbench ~6000

3. patched AICPUPM (w/o plist and c-state in UEFI disable) - 16,34 - all leds on

4. patched AICPUPM + imac12,2 plist (c-state in UEFI disable) - 16,20,24,30,34,35 - all leds on - can't get more then 35 - geekbench ~12700

5. patched AICPUPM + imac12,2 plist (c-state enable) - 16,20,24,30,34,35,36,37,38 - leds changing - geekbench ~12900

6. patched AICPUPM + imac12,2 plist (c-state enable + EIST disable) - 16,34 - leds changing - low geekbench score (~6000)

7. patched AICPUPM + imac12,2 plist (c-state enable + EIST enable + IPB disable) - 16,20,24,30,34 - leds changing - geekbench ~12300

 

10.7.1:

 

1. nullCPU.... 16,34 - all leds on - geekbench ~12200

2. patched AICPUPM (c-state in UEFI disable) - 16,30,32,34,35 - all leds on - geekbench ~11200

3. patched AICPUPM - 16,30,32,34,35,36,37,38 - leds changing - geekbench ~11700

4. patched AICPUPM (c-state enable + EIST disable) - 16,34 - leds changing - geekbech ~12300

5. patched AICPUPM (smbios mbp8,3) - 16,20,24,30,32,34,35,36,37 - geekbench ~11400

6. patched AICPUPM (c-state enable + EIST enable + IPB disable) - 16,20,30,32,34 - leds changing - geekbech ~10700

What version of Chameleon are you using ?

 

thanks

That being said, we already have confirmation that this behavior is also present on iMac12,2 hardware and is being sent to QA and hopefully reach the engineers next week.

 

I did some test on real iMac12,2:

 

16 35 36 37

 

did Apple reply ?

Thank you man. I tired with a ancien version and speedstep is finaly working. DSDT was the problem.

Hi I tried out the Mac Mini 5,1 SMbios so I don't have to mess with the graphics kexts to use integrated graphics. Everything works well with the exception of P/C states. With MSRdumper, I only achieve two P/C states. (16,34). With Macbook Pro 8,1 SMBIOS I achieved 6 states(16,19,23,28,33,34). Anyone else have similar issues or is it something on my side. Thanks.

 

My processor is i5-2500k and the rest of the hardware is in my sig below.

 

Also is this an issue of MSRdumper not recognizing the P/C states for mac mini smbios or them not existing at all. Thanks.

uhmm, I just tested it on my i7 950 . getting constant log as following.

does that mean speedstep is not working? here is the chameleon log

SSDT with CPU C-States generated successfully
P-States: min 0xc, max 0x17
SSDT with CPU P-States generated successfully
RSDT: Added 2 SSDT table(s)

 

I have my DSDT as well. Do I still need to install any drivers for this? I am clueless!

[flAked]

MSRDumper is specifically made for SandyBridge CPU's, I'll take a look on how we can output 1st generation i7 stepping information as well.

thanks, that would be really appreciated

I'm on a L502x i7 2630QM 2nd-MacBookPro8,3

Left it for about 20minutes, multitasking like hell... do those lines represent Speed Stepping being functional?

 

Edit: Used a generic SSDT.aml found in the revoboot thread these are my results now

I was gonna run MSRDumper on real iMac; but sadly i don't know the root password at my local Apple Store. Sorry was hoping to help

[kishunv]

Everything great but no turboboost on i5-2410M.

look few posts above ;-)

[Bansaku]

Curiosity got the better of me after having problems with a friends AMD system and P-states, so I decided to see how my system is running.

 

iMac12,2 SMBios.plist

Fully edited DSDT with no SS edits

 

Bansakus-iMac kernel[0]: MSRDumper PStatesReached: 16 20 35 36 37

 

Like what others have posted, I know I had a few more P-states in SL, including the missing "34". As well, shouldn't I have "38" as well? Perhaps my tests did not take advantage of the single CPU core?

 

Looks like everything is working (almost) great.

[davidm71]

Hi,

 

I just tested out the MSRDumper and not sure if these results are correct for my 2600K (Not Overclocked):

 

CoreMulti(16)

PStatesReached: 16 + 34.

 

 

I have not yet installed a SSDT. My system is an Asus Z68 Deluxe with patched bios to allow native AICPUPM (no speedstepper patch).

Lion 10.7.2 install...

 

Thanks.

[elpocholo7]

Hello, i've got my hackintosh running really smooth and nice (asus p8z68-v pro - i5-2500k - gtx 260 - 8gb ram) and thanks to Flaked's steedstepper i managed to get sleep to work as well as couple p-states. This was achieved by running the system without a DSDT.aml, and once i've started using a slightly edited one in order to get my hdmi audio working properly it messed up my p-states which now are just two, the lowest and the highest (16 and 40). Does anyone have any clue on why this happens once you start using a DSDT ? Thanks in advance

[Hugo_bee]

hy.. I like it. but.. this tool is only to debug/disover if pstate is running fine?

I don't understand if.. within the output.. I have to use those data for other scope..

 

can you explain?

I'm getting a similar response with my 2500k, ASUS P8P67 Pro, with the BIOS hacked to allow native AICPUPM. Lion 10.7.3

I have the BIOS set to clock at 44x multiplier, so my P-states are just 16 and 44, there are no states in between.

[MacFaulty]

Tried this tool on my Core i5 430m (don't know if this is a sandy bridge CPU).

 

Does not work for me I only get CoreMulti(0) with PstatesReached: <nothing displayed>.

I did dump my SSDT from chameleon with pstates=yes and cstates=yes (got message that SSDT was dumped fine).

 

Can anybody enlighten me if there is a fix to show whether speedstep is working or not?

I also tried MSR Tool in x86 mode, there it says my freq is changing (but program shuts down very quickly).

 

I use 64-bit Lion 10.7.3

 

Thanks!

MSRDumper working.

 

Specs:

P8H67-M PRO B3

Core i5-2400 3.1Ghz -System reports 3.2Ghz - with turbo so it should go to 3.4Ghz

Generate C&P-states in com.apple.boot.plist

Using patched DSDT

Are these values correct? I only see the above generated lines.

Don't know if it enters 3.4Ghz?

 

Thanks.

I found a solution for my problem. So I thought to post it here for anybody else this workaround may work.

 

I downloaded IntelCPUMonitor.kext and SMCMonitor app and could check my frequencies and P, C states.

Good news! Speedstep is working

 

Nice job on the MSRDumper.kext though! Keep up the good work!

[Käsesocke]

Hi

How do I unload MSRDumper? Speedstepping is working well but since I ran MSRDumper sleep isn't working anymore. Just the Screen goes black and nothing else happens.

From the directory where MSDumper.kext is located, run sudo kextunload MSRDumper.kext

Hi Insanely MacSage, My birthday's coming up and I'm going to get the hardware for a hackintosh (thanks Dad!). Aside from Xcode, what other languages should I learn to use MSRDumper and RevoBoot? Thanks.

[iLeopod]

For RevoBoot you should especially learn ACPI Source language because RevoBoot is mainly about high customized DSDT/SSDT tables.
