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).

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

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".

> MSI employees rarely come here and post even more rarely.
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<<

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.

Thing is i dont know how to enable CPU fan control/regulation ifd possible. Doesn't realy see anything anything in the mobo manual except mentioning AMD Cool’n’Quiet.
This fan i have installed is running fine but i thk it runs full speed all the time and that makes a lot of noise - not needed.
Thx for any advice/tip/hint

40 °C is fine. The minimum fan speed can be set is a % of the full capacity.
Start with 12.5% and if the fan needs to adjusts it's fan speed too often and it get's annoying you can raise it to 25% or more.

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.

Msi z68 gen 3(gd 80) cpu phase lights

I just put together my pc about 4 days ago, everything worked fine, I turned it on about an hour ago and realize my primary bios failed(i never flashed) it came with bios version 18.5b1. I cleared the cmos and removed the battery and unplugged my psu cord and placed them back the way it should be. I now realize my cpu phase light is constantly blinking and I am not running any program the desktop is just sitting there idling.
Should it be doing that? I don't remember my previous board every doing this.

I don't see the eup2013 and as far as this being an oc failure...it was at 4.2 but i only changed the cpu ratio and everything was all good...I ran prime for 10 +hours and no problem...I am looking for this other test that i saw some guys use to do stability test besides i think it might have been called lightwave or some sort... I ran occt for 5 hrs and i was good, turn my pc on yesterday fine and today bios failure and like i stated before this was stock bios.
I think I remember seeing that in the gd 65 but I don't see it here in the 80...also i have the ballistix ddr3 2000, I am unable to run it at its rated speeds of that I am stuck at 1866. Any comments on that one?
http://www.techpowerup.com/gallery/3152.html that is my pc there...aside from a few upgrades i believe that still shows the gd 65 and the corsair h60 i have since gone with the gd80 n h100 was also thinking of changing the case to the corsair carbide 500r white/black but the only think i don't like is it not having an external hdd dock

P55-GD85 CMOS Pin #s and CPU Phase LEDs

Howdy, folks.
Looking for some information that isn't in the manual.
I have a brand new P55-GD85 that won't POST. Could be a lot of reasons, but I wanted to check that the CMOS jumper on JBAT1 was properly across pins 1/2. The problem: The manual doesn't orient the jumper on the board, and the board doesn't label the pins. Does anyone know whether pin 1 is closest to the battery or furthest from it?
The jumper came from the factory sitting on the pin closest to the battery (plus the middle pin). I assumed that the jumper was properly set at the factory, so I powered down the board and moved the jumper to the other pair for 30 seconds or so, and then re-seated the jumper where it started. Before I did this, powering up the board turned on all of the blue LEDs on the CPU Phase panel, plus LED #1 on the CPU_VTT Phase panel. Now, none of the LEDs lights at all (except CPU_VTT #2 blinks once if I use the reset button on the board). The problem: the manual does explain which LEDs are supposed to light up on boot, normally. Does anyone know? Was all of the LEDs lit a good thing or a bad thing? Now that none light up, is that good or bad? Is there any documentation for this?
The board came with a plastic cover across one of the two, 12 volt 4-pin ATX JPWR2 CPU power plugs (the one closest to the center of the board). Nothing in the manual explains why or whether to use one, two or none of the JPWR2 plugs. Anyone know why one had a plastic cover? I plugged in both halves of the plug, anyway.
Here are the specs on the machine. No overclocking, no tinkering, nothing changed on the board, and no peripherals. I haven't even hooked up the USB headers. Just the front panel power, which I unhooked once I had these problems.
* P55-GF85 w/ i570-LGA1156 (on the supported CPU list)
* 2x2GB G-Skill F3-12800CL9D-8GBRL (correctly seated in DIMMs #1 and #3 -- testing with 1 stick at a time = no change. This memory suggested by NewEgg and reported to work with this board)
* Rocketfish 500W RF-500WPS2, which is not a great PSU long term, but at the moment the board isn't running a single HD or peripheral except some fans. The PSU has 2 12v * 18A rails, and 18A on each of the +5 and +3.3. The manual says "at least 18W" so this may be a problem.
* An old GeForce 6500 card, which may not work, although it gets power.
Thanks, in advance, for any insight.

Google for pictures of the board (large/high-resolutioin images) to compare jumper positions.
The "keep data" position is usually just a parking position that does not much else electrically. So, taking the jumper off the pin header altogether would also make sure that it is not wrongly placed.
Remove the board from the case and test it on an non-conducting surface in barebone configuration (just CPU, one stick of RAM, video card & power connectors [24-pin ATX, 12V CPU power, PCI-Express power connector]). Reseat CPU and heatsink as well and check for broken or bent CPU socket pins while you do that.

Test a video card that works for sure and also test a different PSU if nothing changes,

Big Bang XPower CPU phase Led is constantly moving

Hi, I just put my box together today and I noticed the CPU phase led array is constantly moving. Is this normal behavior? The pc is essentially just idling. Thank you in advance for your help!

Under light/medium loads a few of them will cycle on and off as power requirements vary depending on the CPU load, under a heavy CPU load I'm sure you will see that all of them will light up.

MSI Z77A GD65 - CPU Phase LED Solid State when OC / Hard to boot up

Problems:
1. All settings are at stock and I having the difficulties to boot up. When I press the power button, all my fans light and CPU phase LED lights on and off.No more booting. Need to press several times on the power switch then it only will boot up.
2. Whenever I tried to OC by changing the Vcore from auto to manual, all the CPU phase led will in solid mode. No more blinking. When I set the Vcore back to auto, it starts to blink.
Approach taken:
1. Have tried to disable EUP setting on bios. Results still the same.
2. Have tried to disable all the power saving settings ,results still the same. CPU phase LED keep in solid mode.
3. have tried to clear CMOS several times but still facing boot up difficulties.
In addition, previously when I am using the same hardware with another brand,it boots up normally. No issue.
To add, I am using Vantec Ion 750W plus modular PSU.
tq

If it wasn't such a mission to remove that monster cooler of yours, I would recommend you remove the CPU for a proper socket pin inspection. You may just have to do that as a bent pin or two can cause such anomalies.
I would also test with another known working PSU.
Beta BIOS versions are available here https://forum-en.msi.com/index.php?topic=158257.0 and I have been using the .A67 with no apparant problems. works great.
Always use the forum flasher . see here https://forum-en.msi.com/index.php?topic=119375.0

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.

MSI 870A-G54 (FX) CPU Core control unlock setting error

Hello,
My motherboard MSI 870A-G54 (FX) has strange issue: CPU Core unlock option is not working properly. I've switched in BIOS Cell Menu the setting "CPU Core Control" - Enabled, and after the restart, there is error message about RAM chek - till 3325 MB instead 16 GB, and after that windows7 Ultimate x64 tries to load, but unfortunately displays the Blue Screen of Death. After disabling CPU Core Control option windows start normaly. Also after using MSI LiveUpdate5 and installing BIOS Code unlock Technology 1.0.106, I got the following message: Error Message
PC Hardware details:
CPU - TripleCore AMD Phenom II X3 Black Edition 720, 2800 MHz (14 x 200), Codename:Heka, Core Stepping: RB-C2

VGA Sapphire Radeon HD 4830, Codename: RV770
Windows 7 Ultimate x64, SP1

I'll be glad to have some of your ideas how to handle it...

I also have an X3 720BE. Mine will not unlock, some do not... it's not a built in feature on 'All' CPU's.
That said.. I have owned mine since the beginning of AM3. It has been a great CPU with 3 cores. I have had OC settings at or above 3.4GHz stable.
If you search you can find a lot of OC information. This was an early release AM3, and a lot of owners, forums, test websites etc.. have information available. I still use it in my HTPC.
Owners who have been able to 'unlock' thier CPU's do get extra core(s).. but it's not as stable. I would rather have a stable, able to OC CPU than an unlocked one that can't obtain the OC stable numbers. It's a mind game.
Good Luck
