Frequency drop on C-60

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Apply a change to voltage.

What is the expected output? What do you see instead?
PState and frequency should be unaffected.

What version of the product are you using? On what operating system?
1.0.7
Windows 7 x64

Please provide any additional information below.
When I hit apply after adjusting a voltage, the reported PState on both cores 
drops to "P3" and 444MHz. Changing the Power Plan resets the cores back to a 
valid PState.

Also, when attempting to calibrate P0, the cores constantly bounce between P0 
and P1, even with a minimum processor speed of 100%

Thanks!

Hi,

thanks for the feedback and the screenshot. That is always helpful. You can 
also click on "Log now" and cut and paste from the opened text, if you like 
that more than uploading a picture. Could you just do that and paste the output 
here. It is possible, that there are more than 3 PStates in newer APU's, which 
I just don't know yet.

I've got two questions:
1. What APU is built into your system?
2. Did you use a previous version of BrazosTweaker, where this didn't happen?

Regards,
Sven

Hi Sven,
Thanks for making this program. I've got the AMD C-60 APU. I never tried a 
previous version with this APU, but I'll download one and let you know.

While trying to get the Log Now output, I realized this only occurs if I am 
running with the "Power Saver" profile. Hope that helps. Here's the output 
after making a small change to P2 voltage:

Disregard what I said about it only happening in the Power Saver profile. 
Happens with any profile, as long as the max frequency is below 100%

Thanks for the input. Can you please do the following:
1. Uncheck the "make permanent" box in the service and switch off the system 
(don't restart).
2. Switch on the laptop
3. Start BrazosTweaker
4. Do another "Log Now" and paste it here. Save the log somewhere, since 
another click is going to overwrite it.
5. Do some tuning and click "Log now" again (after having copied the first 
one), if the P3 settings are coming from BrazosTweaker.

I'd like to know, where the entries from Pstate P3 are coming from. That looks 
strange to me. With your help, I might find out and can help. 

Thanks,
Sven

It looks to me, as if the settings for P3 are coming from the chip itself, but 
P3 is actually not activated. Btw, P3 is actually set to run at 615MHz, which 
is little different than what the tool reports (444MHz). I'm wondering, why the 
APU goes to that PState, because it is actually not supposed to do that by 
"P-StateMaxPState: 2". 
Many, many thanks for your time. Please uncheck all options in the service tab, 
if you think, it doesn't work as needed. I'm not considering this as any risk 
for your system, but it might influence the time you can run on battery.

I will to fix that problem as soon as possible, but due to not having this 
piece of hardware you have, it can be hard to find the root cause.

In addition to encountering the same issue above (dropping into P3), I 
additionally found that modifying the voltages for P1 (P2 at default and P0 
changes seem to have no bug) causes the C-60 to lock into P2. This might be 
some kind of (thermal?) failsafe since stopping the workers on prime95 allowed 
everything to return to normal operation. I think thermal might be the culprit 
since this condition is not consistently triggered at the same voltage drops 
and restarting the p95 workers doesn't necessarily cause it to return to the 
P3/P2 locked state.

As far as the bouncing between P0 and P1 as noted in the OP, I don't think 
there's anything we can do to control this since entering the "turbo" P0 state 
is (in theory)  controlled at the apu level based on some predefined thermal 
envelope. Effectively, windows treats P1 and P0 as the same 100% state and the 
apu decides for itself which cores have the capacity to run at P0...

Hi,

Since you are talking about thermals. What are the temperatures, while seeing 
the CPU being locked in P2? 
The next thing, I'm wondering is, why there are P3 settings available, but 
actually they are not supposed to be used, since P3 is not activated (see Bit 
63 P-State0 0067).
I'm curious, if the CPU goes into P3, without having the BrazosTweaker service 
running (uncheck everything on the service tab and power off the system - power 
on). I would like to know, how the CPU Pstates behave, if BrazosTweaker is just 
monitoring (CPU-Z can be used too).
As I said, I'm not owning a C-60 or any APU with turbo, so I can't test. What I 
know, is that the turbo works completely different than in Phenoms or Llano. 
There are no Boost states.

I have (most likely) the same Acer 722 with a C-60 as original poster and am 
not experiencing these problems, even after running prime-95 for 10+ minutes 
and thermals not seeming to go above 65C. This is with combinations of CPU 
cooling set on either active or passive, and CPU frequency at either 90% or 
100%.

I do recall something like this in a previous version of BrazosTweaker that I 
tried to use (1.04 I believe) and ended up not using it because of this. Fast 
forward a bit and I tried using 1.06 and didn't have this issue. Upgrading just 
now to 1.07 and testing more, I still can't replicate this. Might it be AMD 
driver (Catalyst Control Center) related in any way, as I now have this turned 
off. I can plug the original hard drive back in and run it on an OEM system if 
that would be of any help to you.

Much appreciated for the work you put into this, hope I can be of some help.

Another thing that I noticed is that in the main program window, there is P0-P2 
and NBP0, NBP1 (pic). When I click the service tab, I see P0-P4 and no NB 
values (other pic), and one of these values is set at 444, the other being 333 
as in the first posters image of the NB frequency. The voltage values of NB P0 
and P1 are the same as P3 and P4 in the service tab, and change when I change 
them in the main window and update. Might this be related?

Might be off topic but after playing with CCC and AMD drivers, my NB seems to 
be stuck in P0 state at max (first pic), and my temps have risen 10C+. This is 
happening independent of BrazosTweaker service running or not.

Hi Alex,
I noticed you are using version 11.10 catalyst drivers. I'm still using the 
original drivers that came with the computer (8 something). Maybe that is part 
of the problem. How did you get 11.10 to work with the C-60? I searched AMD's 
website, but they don't list any drivers for the C-60.
Thanks,
Jerry

Hi Alex,

thanks for the feedback. Always appreciated. 
To your question about P3 and P4 looking like NB P0 and NB P1. That is actually 
right. On the service, the NB Pstates get handled internally like the CPU 
Pstates (has to do with the programming), thus the numbering is just increasing 
(could be cleaner, I know ..).
Question about NB P0: Take a look into the advanced power options under 
Powerplay. You will find the settings for battery and plugged-in. Play around a 
bit there and keep in mind, how the NB Pstate switching is doing with the 
different settings.

Furthermore, it is very possible, that CCC is playing a role regarding the 
reported behavior, which that issue was opened on. Please update to the newest 
version.

Regards,
Sven

What I did:

Insert OEM harddrive, system restore to OEM state.                    -> Had P3 
Bug
Uninstall all bloatware and any non microsoft services.               -> Had P3 
Bug
Install Catalyst 11.10 Drivers and turn off CCC                       -> Had P3 
Bug
Change power options of power saver to match balanced.                -> Had P3 
Bug
Open BT-> Service-> Make permanent-> Update-> Restart Comp->
  Open BT again and attempt to make changes                           -> No P3 Bug

Removed OEM Drive and install SSD (one with no bug                    -> No P3 
Bug
Open BT-> Service off-> Restart comp-> Power saver-> Change values    -> Had P3 
Bug
Open BT-> Service on-> Restart comp-> Change values                   -> No P3 
Bug

So apparently the driver versions I had made no difference, nor did 
uninstalling CCC. I simply always had the service running. When you start 
BrazosTweaker without the service first starting, and being in either 99% CPU 
max limit in any power state, or in power saver mode (with oddly enough 100% 
CPU max), it bugs out. When you have the service running already at windows 
start, it seems to do fine, and can make changes without it sticking in P3. It 
does however jump from time to time into P3.

Thermals don't appear to matter, as it happens even after CPU idle for a while, 
hardware monitor showing sub 60C (52C tested).

The stick at 444Mh NB P0 state happens whenever I choose Maximize Performance 
as the ATI graphics power setting, and drops to NB P1 when I choose Maximize 
Battery Life. Running furmark does not seem to make it jump to P0 if in Max 
Battery mode. Not sure if this is useful info to you but just noting that it 
doesn't work like a turbo core.

jbud2: The drivers are simply the AMD mobility drivers. If you go to the amd 
website, and click "support and drivers" just above "find a driver", then on 
the next page there is a link available for AMD Mobility Radeon / 64 Bit 
Windows, and click download on the next screen. It will download an installer. 
I believe that's the one I used that recognized the card.

Hi Alex,

thanks for trying all this. 
At which point did you install BT on your OEM harddrive? Right in the 
beginning? 
Just for information: Before activating the service ("Make permanent") or 
changing a setting, BT is really just monitoring and doesn't write anything to 
the registers. If the P3 bug was already apparent before enabling the service 
or changing any voltage, the issue can not be caused by BT. Btw, I'd like to 
know, what CPU-Z is reporting as frequency, while seeing the CPU in P3.

Let me know your thoughts,
Sven

I installed BT right away on the OEM drive, but did not have the "make custom P 
states permanent" checked. To test each variable I simply changed the voltage 
and clicked apply on the main window. It doesn't jump into supposed P3 just 
from changing the number for the voltage, but from hitting apply.

CPU-Z shows it dropping from an 8x to a 6.15x multiplier when clicking "apply" 
on the main window in BT, roughly 624 Mhz (picture attached).

Once you hit "Apply" BT will write to the registers, which can possibly lead to 
having a fourth (P3) pstate being set up (not sure how, but maybe). The thing, 
I like to know is, if there is a P3 pre-defined before hitting "Apply" or 
enabling the service. I believe, this can be checked by disabling the service 
and switch off/on the system. On restart start BT and do a "Log now", without 
anything else. If I know, that BT is creating the entries for P3 and I can 
debug the code, but until now I'm not convinced, that BT is the culprit. 
Currently I have no clue, how this could happen.  

Ok, at least I know now, where the 444 comes from. It's equal to the NB 
frequency from NB P0. This is because, I'm not considering getting a fourth CPU 
Pstate and pointing in the frequency array on the value for NB P0.

To be clear, I'm not actually disabling the service in windows 
msconfig/services/registry, I'm simply checking/unchecking make P states 
permanent.

Also, on a fresh restart with the service off, even if i move P2 voltage from 
say 1.0250 down to 1.0125 then move it back up to 1.0250 and only after hitting 
apply, it still does it. So I didn't really change the values at all.

So I did these things in order...

Unchecked make custom P states permanent and hit apply.
Made sure power plan was set to power saver.
Close program and restart computer.
Opened CPUZ and saved log [noservice-cpuzlog]. (dunno if you may need it)
Opened BrazosTweaker and saved log [noservice-BTlog].
Changed value of P2 voltage up one notch, then down one notch, then clicked 
apply (no theoretical voltage change).
BT now showing 444Mhz and CPUZ roughly 630Mhz.
Saved logs of CPUZ and BT [apply-log].

Let me know if you need anything else.

Hi Alex,

Thanks! The logs you saved from CPU-Z and BT match in regards of the MSR 
0xC0010067 register. This one stores the values for P3. This PState seems to be 
pre-defined within the C-60 APU, but not activated. It tells me, that BT is not 
writing to this register as you haven't done anything with BT before logging 
with CPU-Z. 
What I really need to do now, is trying to figure out, why after hitting apply, 
P3 is activated. At least, I know now, that the register writes (P3) are not 
from BT.

Btw, the service gets activated/deactivated by checking/unchecking "Make 
Pstates permanent".

Regards,
Sven

Enabling the service allowed me to stay out of P3. Thanks Alex and Sven.

Enabling the service wasn't helpful in my case.

This also happens to me: "When I hit apply after adjusting a voltage, the 
reported PState on both cores drops to "P3" and 444MHz". 

But only when using Cool 'n Quiet in the BIOS. After I disable it, I more or 
less don't have this bug. 

Thing is, I really-really thing there's a HUGE NEED for a forum for this 
project. There are too many variables and different hardware/vendors, so I see 
a need to open up a forum and/or mailing list, in order for us to communicate 
and help us each-other. 

Please Sven, do open up a forum and a mailing list. Thanks in advance!

Hi henrique,

I totally agree with you. We are DESPERATELY in need for a FORUM for this 
project in order to help may of our users. Hope Sven can consider about this.

I found a solution for this problem. When the 444 MHz situation appears, just 
go to "Super Hybrid Engine" and choose "High Performance". AFAIR, The P-State 
comes back to P1 and the Mhz goes to 1333. Then you can try changing back the 
frequencies and choosing "Power Saver".

Hi myboy.myboy,

Just start a discussion for instance on http://forum.notebookreview.com and put 
a reference in here. I can set a link on the homepage to it later on.
