PhenomMsrTweaker: Cool and Quiet customized

[Glaucous]

Hello.

I recently installed Windows 6 64 bit and now the program works!
However, I want to use three states or more, because my overclocked state got some higher vcore than the unclocked one, obviously.

W7 x64
Phenom 2 x4 940

I downloaded this modded version:
http://www.hardwareluxx.de/community...&postcount=171

Seems to work well, however, I don't understand the "Overall CPU load threshold" options, here they arem the different states are called Low, Middle and High:

Overall CPU load threshold (%) high/low: 24
Overall CPU load threshold (%) high/middle/low: 24
Overall CPU load threshold (%) middle/low: 24

Could someone explain the differences? Right now my states are at 800 MHz, 3 GHz and 3.6 GHz, and when idling or just using the webbrowser it constantly jumps between state 1 and 2, which shouldn't be needed.

I used K10Stat before, which I rarely had to jump to state 2. And it doesn't make sense that it should, 800 Mhz is plenty for that.
Anyone who might have an idea?

Hello Glaucous,

I have tried the 3-states modded version and I have the same problem as you except that I have toned it down a little bit.

I did not fully understand the way the 3 CPU load thresholds work since I have tried many settings and I was not able to conclude anything major.

I am running a Phenom II X4 720, and my settings are the following:

High:15x, 1.3250v
Middle: 8x, 1.1000v
Low:4x, 0.8250v

Overall CPU load threshold (%) high/low: 60
Overall CPU load threshold (%) high/middle/low: 55
Overall CPU load threshold (%) middle/low: 45

Let me know what do you think.

Also, what about K10Stat? any good?

I registered pretty much solely to say thank you to Kink for this terrific program.

My gaming framerates in WinXP tripled compared to stock CnQ with a recent Regor 240 system. More details here.

I do have two questions/items for Kink (or others) (and apologies if they were answered already in the six-page thread):

• First off, MsrTweaker seems to work fine whether I disable CnQ in the BIOS or not. I am assuming the only potential problem with NOT disabling it would be that if I accidentally selected minimal power management in display properties, the official CnQ and MsrTweaker could conflict, correct?
• Secondly – MsrTweaker really shows relative values - for example, I wanted a voltage of 1.2 and 1.1 for CPU Vcore. MsrTweaker does fine with my Regor if I don't mess with the BIOS voltage - it drops the stock 1.425 by 0.225 to set 1.2 at the CPU. However, at one point, I had the BIOS voltage lowered by 0.15 or so, and setting MsrTweaker to 1.2, it still dropped that by 0.225, resulting in 1.05 at the CPU - bottom line, any BIOS voltage correction will be added or subtracted from MSRTweaker's selected value.

Finally, I have not tried and have no reason to try the tri-state version that was asked about above and Kink said on the previous page the labels were confusing, but I have a WAG as to what the settings should be – but I could be totally wrong.

For tri-state, you really only need two transition values – i.e. low to medium at 40% CPU load, and medium to High at 75% CPU load (Kink’s file only has one value for low to high).

A previous post said the default values were 32, 32, and 32 – which comes pretty close to adding up to 100% - but not quite.

I am thinking those values would make the processor transition at 32% and 64% usage, and if you wanted my example above of 40, and 75, you would set the values from top to bottom at 25%, 30%, 40%.

I.e. – I suspect the bottom number is processor load before the medium transition, the middle number is additional load until the high transition, and the top number is just 100 minus the other two values.

But I don’t speak or read German, I am not the author, and I haven’t tried the program, so be careful with anything I said.

Again - thanks to Kink for the original version.

[xsever]

I have switched to K10Stat, and it allows for far more customizations, and 4 states. Had MSRTweaker had that, I would have sticked to it.

K10Stat also has the option to choose which load method to consider. Highest core value, average value above all cores, lowest value...

[bobruto]

Kink, that is a nice little program you wrote.
It is certainly more user-friendly than the other one I've been trying to use.

However, for some reason it doesn't work flawlessly on my hardware (PII x3 710/Gigabyte ma-790x-ud4/WinXP x86)
What I want is to enjoy benefits of both overclock and CnQ. OC set up in BIOS right now is HT 255 / 13x / Vcore 1.375 - it boots up and works 24/7 in this mode if I want it to. There're a few lower power modes that also work fine, the lowest being 4x / Vcore 1.0

However, PhenomMSRtweaker (and neither the other program, cnqsvcOC) seem to be able to switch between these modes without a hitch.
I've entered the numbers into the program, but when I try to activate either, it only seems to change the voltage and not the multiplier:


cnqsvcOC had the same problem: voltages switched just fine when it switched p-states but the multipliers went haywire and the CPU never ran at 13x.

Ideas / advice will be greatly appreciated

[Tiger-Heli]

I'm an Athlon novice, but a couple of things I noticed:

You have to click "Apply" on the main screen and then "Make Settings Permanent" and "Apply" on the Service screen for it to work properly.

If you don't have a Black Edition CPU and 13x is more than the stock multi, it probably won't work.

[bobruto]

13x is stock, I wrote that I have it set up like this in BIOS
It's running at 13x255=3.3GHz right now

[Tiger-Heli]

Not positive on this, but ...

Make PMT takes over for CnQ, so first make sure you have something besides Laptop on Minimal Power Management in your Windows power settings.

The first screen looks correct, so click Activate on P0 and then Apply, then click Activate on P1 and Apply. Then click Service and click "Make Settings Permanent" and Apply.

Now if you right-click and select High-Performance you should should be at 13x, Power Saving you should be at 4x, and Balanced, it should shift with CPU load.

If that fails, I'm not sure what to tell you to try ...

Do you have CnQ enabled, and does CnQ work normally without PMT loaded?

[bobruto]

Both activating customized pstates manually ("Activate" buttons) and allowing the service to do it only switches
Vcore and not the multiplier (once it's down to 4x). The program isn't that hard to master


> Do you have CnQ enabled, and does CnQ work normally without PMT loaded?

I keep it disabled, but just checked to refresh my memory and it doesn't work (likely because I increased Vcore in order to overclock the CPU)
Of course it worked with the stock numbers and I believe it worked with an OC which didn't involve increased Vcore, but that wasn't
high enough

[Tiger-Heli]

I don't think I can help you more - I ran stock clock and decreased voltage to keep the PC cool. PMT worked fine for me, but other than dropping back to the stock clock and testing if PMT works with that, I don't know what to suggest.

[kink]

@bobruto: If I understood correctly, the multi is actually changed - at least once, down to 4x, but then raising it back to 13x fails. Try to use 'Auto' as multi in the BIOS menu and see if that works, if I recall correctly there were some reports about C&Q not working correctly if the multi is set manually. Always depends upon the BIOS implementation...

@Tiger-Heli: Thanks, glad to hear there's another happy user. About your questions:
1) You almost got it right. The problem is that if the active power scheme allows CPU throttling (such as the default 'Balanced' scheme, not just the powersaving one), standard C&Q is active if enabled in the BIOS, conflicting with custom C&Q and resulting probably in a mess (haven't tested it myself).
2) It's not about absolute or relative voltages - you change the voltage IDs (VIDs), not the actually delivered voltages. They may correspond to the actual voltages (more or less), but that depends upon your BIOS and mainboard. In your case, the BIOS adds a fixed offset to the voltage IDs; my BIOS (ASUS M3A78-T) alters the voltage IDs for P0 (but does not allow to customize the other P-states). This topic has already been covered in this thread, I think.

[Tiger-Heli]

Multiplier - That makes sense as I think mine was set at Auto.

1) We might be saying the same thing here, but from what I could test of it, the Windows (XP) power saving state made a difference. i.e.:

• CnQ enabled in BIOS, non-throttling state (Home Office, Always On, Presentation), PMT worked fine whether in Balanced, Power-Saving, or Perfomance.
• CnQ enabled in BIOS, throttling state selected (Laptop, Minimal power usage), you might have conflicts - IMS, the Windows CnQ would over-ride PMT, so you might not have all cores locked, etc.

Since there is little reason to select a power saving state with PMT running, it didn't make much difference, but better safe than sorry.

2) It probably was covered in the thread and the distinction was lost on me. With BIOS VCORE (VID?) set to normal, CPU-Z values are VERY (0.002) close to PMT requested values.

[kink]

1) Yep, I forgot that you're using WinXP
2) Your BIOS VCore entry should actually be named 'VID offset' as you actually set an offset applied to every requested VID (difference between the selected VCore and the default one). Mine, on the other hand, should be called 'P0 VID' as that's what it controls. It would be nice if open-source BIOS implementations replaced the two monopolists; the community could deliver excellent stuff (see projects like openwrt for routers). But artificial product differentiation by castrating available BIOS options and the like seems to be one of the most important aspects for mainboard producers, sadly.

[Tiger-Heli]

Open source BIOS would definitely be interesting - I'm amazed for example, how much better your app works than AMD's CPU throttle handling.

[bobruto]

changed it to Auto, same thing
Once it dropped down to 4x, I made the 2 states in PMTwkr the same, setting them both to 13x/+0.1V but to no avail.

Where do I look now? In Gigabyte's customer feedback section?

UPD: went to the gigabyte site, typed in a long post describing the situation, but before submitting it, decided to try
other multipliers for P1.
And what do you know, it works just fine if you use anything above 5x!
So apparently 1.27GHz @ 1.0V is stable, PMT works like a charm and I'm a happy man
Thanks everyone for listening!!

[Stabwound]

Hey, does anyone have any idea how to get this to work in Windows 7 x64 RTM? The older version without the service works fine, but the newer versions with the installer just instantly close with a "phenommsrtweaker has stopped working". Any ideas? =(

[Veacheslav]

Stabwound, I am also using Win7 x64 RTM, and I have no problem with Tweaker v1.2.2. Maybe something is wrong with your windows installation?

[Bkobe7]

Another happy user. Works great in WinXP 32-bit. Thanks, kink!

550BE @ X4 (B50)

# consec samples for P0: 8
seems to control jumping from P-state to P-state fairly well. Is it harmful to the CPU/mobo to have it fluctuate between the 2 states, say, twice every second? If not, then it's probably better to lower the # of samples for P0 back to default.

3.3Ghz @ X4 1.328V idle
800Mhz @ X4 0.992V idle

[haraakiri]

Do we have an intel equivalent tool which runs on windows 7/vista 64? I tried RMClock but that doesnt work, perhaps requires me to login as admin. I tried disabling UAC but still didnt work . For my AMD system I use k10Stat.

[Bladesinger7x]

I was wondering ...is it possible to make 2 or 3 icons on desktop for each
p-state so that I could manually select the p-state

[Bkobe7]

What I do in WinXP is put a shortcut in the 'startup' folder and set the program to run minimized. Then you can right-click the icon in the task bar and select the desired p-state.

Thanks ...this seems to work ...at least in theory (I'm using the
3 p-states mod with Vista x64).

When set in this way (BIOS C&Q disabled, custom C&Q disabled), and
set to PowerSaver the system starts in Performance mode

What I would like is that the system starts in PowerSaver mode and
only when manually set enters Performance mode. Can this be done
...also is it possible that the PowerSaver mode is applied only once
Windows starts (to avoid any possible crashes dorring boot up)?

Damnnnnnnnnnnn lovin' this new 555:

I can't get it working on PII 955 + GA-790FXTA-UD5 + W7 x64. When i start program windows pops this stop error:

Yeah I couldn't get it working on an early Win 7 beta build as well. It may have to do with drivers or something. Many users report the same issue.
