What is CPU Phase control?

In my P67A-C45 green power menu the first option entry is CPU Phase Control and there are two option: what is difference from APS and Intel SVID Mode?
Thanks in advance!

CPU Phase Control refers to the load-dependent automatic CPU PWM Phase switching logic (the number of phases used varies with CPU load). APS is the board's control logic and Intel SVID is the CPU's own control logic for this kind of phase control. Use whatever works best for you.

CPU phase control by default after wake up (Z97 Gaming 3)

Hello,
I've juste bought a MSI Z97 Gaming 3 to replace my MSI Z87-G45.
I want to inform you that when CPU phase control is set to "optimized", this setting is restored to default mode after waking up.
I made many tests to confirm this :
- with optimized before sleep and wake up, my IDLE consumption is 37W
- with optimized after sleep and wake up, my IDLE consumption is 42W
- with default setting, my IDLE consumption is always 42W
Changing Windows energy settings didn't fix this issue. Changing wake up settings in the BIOS didn't correct this issue.
Could you fix it in your next BIOS ?
Moreover, I didn't get what it exactly came from but my system crashed few times. It seems that it is a problem with fast RAM boot setting.
Thanks

CPU Phase Control

My cpu phase control led lights no longer works. None of them are on, even when I load the default settings. The question is it just the lights or the whole phase control? Did I turn these on/off accidentally? I just bought this board on Dec. 26th from NCIX but it is a revision 1 board. I think I read somewhere rev. 1 boards seemed to have the phase control problems but not sure if this is true or not. Please advise on a solution or solutions to try before I RMA this board. Also can you let me know the differences between rev. 1 and revision 1.1?

Please unplug your PSU from A/C power and >>Clear CMOS<<. Then load "Optimized Defaults" in BIOS Setup and check your APS Settings.
Also, please tell us your current BIOS Version. >>Posting Guide<<

Usually only minor changes, that are generally not documented anywhere. So no, I have no idea what the exact differences are. Sometimes it is just a different type/brand of capacitor that will make them changes the revision ID (which on the other hand does not mean that there was any problem with the original layout -> so, rest assured, the fact that you do not have a revision 1.1 board does definately not mean that the revision you have was found to be "faulty" in any way).

P67A-GD55: "Adjust CPU Ratio" disables "CPU Phase Control"

I'm using P67A-GD55 (BIOS ver.1.7) and i5-2500K.
I changed "Adjust CPU Ratio" and I found "CPU Phase Control" was disabled automatically.
1. Click "Green Power" and set "CPU Phase Control" to "APS Mode".
2. Click "OC" and set "Adjust CPU Ratio" to "33"
(It's a default value, but please click the number "33").
3. Click "Green Power" and check "CPU Phase Control".
It is changed to "Disabled".
Please keep "CPU Phase Control = APS Mode".

Thanks for the info.
I had another account and I reported a BIOS bug a few years ago.
MSI fixed it soon.
I remember that, so I bought the MSI mainboard.
I hope this post would help other P67A-GD55 users and the MSI developers.
Note for users:
MSI will upload the latest BIOS to the Taiwanese site first.

Green Power CPU Phase Control + C-STATE + Turbo Boost ?

Does anyone know if we can turn on MSI's Green Power CPU Phase Control + Intel C-STATE + Intel Turbo Boost in BIOS all at the same time? Any problems with doing this? Does MSI's Green Power CPU Phase Control override or conflict with Intel's C-STATE? And will Turbo Boost kick in if turned on when a core needs it even if Green Power CPU Phase Control and C-STATE are switched on?
I really like the idea of the PC running cool and quiet when doing lite work, but would like full power on demand as well.
Thanks.

I'm using Intel speedstep (EIST) but i disabled c-state because this brings a unstable PC for me.
I'm using also the greenpower genie and it works very well.
When i don't need the power my PC falls back to 50% 2154MHz (this you can choose in the energy configuration of windows), when i play games or decode movies it goes up to 100% 4130MHz. And it is stable as a rock tested 24/7 prime 95 and OCCT and Intel burn test.
My settings are=
Eist enabled
Turbo enabled
C-state disabled
Greenpower auto
My CPU temp in idle is 24° cores 38° and this on aire (room temp 21°-22°) Load 100%=CPU 60 and cores 70°-72° ( prime stressing), gaming CPU 42°-45°.
For more info on my sys. follow link and see my overclock and voltage settings.http://www.hardware.info/nl-NL/usersys/cm9xZ51mk2yd/view/
I also changed cpu skew and ioh skew to 200ps so i don't get BSOD that says :cpu did not receive clock on time , but this is only necessary when i go above 178 MHz BCKL.

P67A-GD65 (B3) CPU phase LED always on

After BIOS update to the latest 1.C0 (I think), on-board CPU phase LED operates wrong. All 6 lights are always on, regardless of actual CPU phase state. MSI control center reports variable (depending on load) LED state meanwhile.

At this time please provide your full system spec. >>Posting Guide<<

785GT-E63 and cpu core control

In BIOS 7551vS4 MSI removed cpu core control, ie, I can't disable the broken kernel, if what some Athlon II X3 is not critical, I can use old BIOS, but for the Phenom 960T is a problem. This CPU supported just starting S4 bios
How I can use 5 cores? I want to return this option or add processor microcode in the old BIOS.

All cores are enabled by default (Auto). The other settings are meant to limit the enabled cores.

Cpu fan control problem

I hope maybe somebody here can help me out, I dont know where else to try, please be gentle with me, just a newbie!
I have a Medion 1918 desktop pc purchased in nov. 2004 and I was very happy with it until it quit working about 8 weeks ago. The machine would not post, and subsequently was returned for repair to the manufacturer. Making a short story long, it took almost 8 weeks to get it back in my hands and its just not the same as it was when it left here..
The motherboard was replaced with a ms-7041, and all I can tell you is its a 865pe, but I cant find any info or documentation on the msi site for this model. I do not even know if this is the same board model that it replaced.
The problem is the computer now sounds like a 747 taking off, I mean this thing is so loud now. The fan spins at full speed all the time now, whereas before it would throttle up or down depending on what the cpu was working on, or if it was just idling. I have also noticed I dont have a "pc health status" when I go into the bios, so I cant even tell what the cpu temps are or what the fan speeds are currently running at.
I probably will need to give more info, but I dont know what else you guys might need to know to help me out.
If there is anyone who can help steer me in the right direction to rectifying this noise, I would be greatly appreciative.

Thanks Danny, after much reading in these forums, and other similar questions, I had a feeling you were going to say that.
I realize now its an oem board and theres not much help from msi. But I was hoping somebody might have some ideas why its so loud now and wont vary the rpm anymore like it did. Also, what about the pc health status? Shouldnt there be one on a current cpu/mobo of this speed?
On the downside, so far, its not been too easy of a go with the folks at medions customer care, which is why I was looking for other opinions here.
I just cant run this machine like this. If I had a meter, I would bet the noise is above 80decibels. You cant even turn up the pc speakers loud enough to watch a dvd. Medion tried to tell me they probably changed the fan, cuz its only a three pin connector, and that the variable rpm fans are four pins and that this replacement mobo wouldnt connect to the old fan, but it looks like the same fan got put back on to me, cuz its dirty and got some dust bunnies stuck in there. So I dont know what or who to believe.
A few more questions to add to the pile...
What controls the variable fan speed on these p4's, bios?
Is it unusual that there is no pc health in the bios settings?
Thats all I can think of right now, I must shut this thing down for a couple hours cuz I'm going deaf and cant hear myself think.

P45-C51 - Noise from CPU Phase LEDs

Hi,
I've just finished setting up a new PC based on the MSI P45-C51 (MS7519) mainboard (see full specs for the system in my signature).
Everything works fine, but.. The CPU Phase LEDs LED1, LED2, LED3 (the three blue LEDs in the upper right corner of the mainboard) emit some kind of very annoying high frequency noise as they flash (in sync with the hard drive activity LED on the front of the cabinet/tower).
It's very important for me that I have a silent PC, so I've gone into great detail choosing the most low-noise components for this specific machine. Everything on this machine is very silent - except for the motherboard, which I would have expected would be the least of my problems when creating a low-noise PC!
So my thoughts and questions are:
- Is there any way I could turn off the flashing of CPU Phase LEDs (in BIOS, jumpers, software)?
- Could it be a PSU issue (is 400W not enough for this setup)?
- Or is it just a faulty mainboard (has other users experienced a similar noise from these LEDS)?
I don't even see the reason for why the LEDs are there. The mainboard manual only has a very short and practically useless explanation of the LEDs. It only says what power modes they show (1 and 3 phase power mode) - not when and what to use them for..
Hoping that someone can shed some light on this issue, and hopefully help me solve the problem..

Now that I found out that the problem wasn't related to the LEDs on the MSI mainboard, I shifted my focus towards the CPU - The Intel Core 2 Duo E8400.
From searching/reading about this specific processor on various pages found via a Google search, it sounds to me like a lot of other users have this issue to - it's called CPU whining - some kind of piezo vibrations caused by the extra power (that would normally be used by the CPU) which is being thrown back into capacitance when SpeedStep throttles down the CPU (no load). So it's not the CPU per-say, but the capacitors and voltage regulators that generates the noise (at least from what I am able to read). I guess it's not directly related to the MSI mainboard, and so maybe this post isn't even relevant in this forum any longer..
When I write it's not directly related to the MSI mainboard, I mean that perhaps if I mounted this CPU in another mainboard, maybe the problem would go away - so I think it might be the combination of this specific motherboard and this CPU that creates this noise. A lot of other Intel Core 2 Users doesn't seem to have this problem, while others again complain about it. I guess it's also a very subjective question about how sensitive your ears are to high-frequency noises (probably in the 15.000-18.000 KHz range). Some write that they hear the sound, but don't care, while others hear it (and like me, are annoyed by it) from across the room through music, conversation and/or other background noises.
Long story short, the users of the MSI HQ Forum (especially Jack t.N. - a lot og appreciation and thanks goes out to you, my friend ) should not use more time and effort on this issue..
Except if there's something that I might still have missed in the BIOS settings, that you think I need to try out first, or if this "newfound knowledge" raises any other questions or inspires a possible solution!
I will leave the post open for a few days just in case.

Not booting/no signal (CPU Phase LED's)

I was at a LAN recently, were my computer worked as normal. I tidied some of the cable management, and when I turned it on, there was no signal to the monitor. I noticed only 1 of the 4 CPU Phase LED's were lit. (MSI Z77A-G45) I've tried without GPU, different memory configs, another PSU, without drives. Still no signal.
Any help would be appreciated!

>>Clear CMOS<< and retry with one stick of ram. Did you run Live Update lately?
Cleared CMOS and tried with 1 stick of RAM. Same results :/ Does is matter what DIMM-slot the RAM is in? I can't remember anything about Live Update, as I said it worked perfectly at the LAN-party before I got home. What does it mean when only 1 of the 4 CPU Phase LED's are on?

Want to know what exactly is flow control in odi

Hi Experts
I want to know what exactly is flow control in odi.can anybody explain with an example.i have created a simple interface ie using contol append km .in this both the tables are in one data server ie in different schemas.in this interface i have set the flow control as false.in what circumstances we will use this flow control.
Regards
sree

Hi Sree,
Couple of points u need to aware.
There are two ways of Constraint checking in ODI (PK, FK, Condition, NOT NULL etc) using CKM.
FLOW_CONTROL: If u enable this in ur IKM all the constraints checking will be done at I$ table (before target table loading).
STATIC_CONTROL: If u enable this in ur IKM all the constraints checking will be done at TARGET table (after target table loading). In this case u need to DISABLE the constraint first and once STATIC_CONTROL is done then u need to ENABLE it.
So all the violated/errored record will be moved to E$ table in both approach.
Makes sense?
Thanks,
Guru

I don't know if that guy at the Apple store is stupid because frankly, I don't know him.
But seriously, if he can work better with a mouse then he should use one. I'm sure there are still some people out there who don't like to send email and type a letter with a typewriter then put that piece of paper into another piece of paper (envelope), carry that to the post office which puts those pieces of papers from one truck to another to finally get it to their destination. You get the idea.
The bigger issue is that people don't realize that they get accustomed to a device that is a a compromise to begin with, the mouse. Just think about it what it takes to scroll down in a window on your screen.
In perfect world: You would take your hand and scroll down the window (or tell the computer the command)
Instead, you take your hand, grab a thing (A) that has nothing to do with the window. Now you move that thing A and you see that it corresponds to another thing (B) on the screen, the cursor. No you have to move that second thing on to a third thing ( C), the scrollbar. And now, instead of moving down the scrollbar, you have to move it up in order to move the actual page down. How many un-intuitive (or counter-intuitive) steps does the brain have to learn and process? This is insane.
People are used to it and they don't question it as long as there is no better solution.
Instead of moving a thing that moves a thing that moves another thing. You just move THE thing. The original solution is touch the thing that you want to move. That's why kids use the iPad or iPhone with no problem. It is intuitive and you don't have to learn a compromise. The Trackpad is at least half way there.
Remember when Apple changed the direction of the scroll bar recently. Another great example, where people get p**** when something get easier but they want to keep their old way "moving something up in order to move something down".
I don't say that the Trackpad is perfect (it has other issues) and yes it requires some "un-learning" of old habits. It is still a compromise. My first computer was a Commodore64 about 25 years ago and I used mice all those years but I didn't' have a problem dropping that "thing" in a second.

What are the phases in requirements gathering process?

Hello
What are the phases in requirements gathering process?
Lets say we start from meeting with business , several workshops , etc
Is business Blueprint the final phase of this process?
Whats the difference between Business Blueprint and functional spec?
Thanks

Hi ,
Blueprint is the starting phase of the project. First there would be requirement gathering according to the client requirements. Then according to these requirements functional specs would be made. Based on these functional specs technical spec would me made and once approved from the client development would start.
This is just an overview. Hope it helps.

P55-CD53 Phase Control

I run all 4 cores of an i5 at 100% at 2.66GHz 24/7 without Turbo Boost and without any other overclocking. I have DDR3 1333 memory running at 7-7-7-21 that is not overclocked either.
The MSI Phase Control can't make up it's mind if it needs 3 or 4 phases so the first 3 lights are on constant and the 4th light blinks very rapidly all the time.
Is this okay? Do you think I would be better off disabling Phase Control so that all 4 phases are always on?
Thanks.

What happened to the controls in QuickTime?

I like the new look of QuickTime, but what happened to the controls for editing video? I used to be able to hit the "I" key for inpoint, and the "O" key for endpoint, and then hit delete to remove that section. Now, I have to drag the selection tool around to do the cut. This is very awkward, especially when I need to fine-tune the areas where the cut is to be made.
Are there any tips on doing some more fine-tuned edits in QuickTime?

I second SwagMeyer's request. He's not asking for any advanced trimming feature that would make things more difficult for the simple user: the IN and OUT shortcuts were presents and "invisible" also in QuickTimePro 7 and they would not affect that easiness of the application.
