{990FXA GD-80 v2} Phase LED noise

I hadn't notice this before. There is a frequency pitch that corresponds to the Phase Switching LEDs in the top right corner of the board. It isn't loud enough to be much of an annoyance and the system runs stable. My bios version is 13.1 and I've enabled CPU and DRR Phase Control settings. Doing so didn't mute or stop that noise, though...just made the LED lights flash when my CPU was being active. I've read other sites and watched youtube vids of people complaining about that noise but there's no clear answer as to whether it's a faulty symptom or just normal/harmless.
MY Set Up:
Board...gd80v2
CPU...8350
RAM...4x4gb 1600 Vengeance
PSU...HX650
GPU...MSI 7770oc
CASE...C70 (Xig Dark Knight II HS)

How loud is that noise? I have a GD80 V2 and 8350 and can look down through a top fan and see those LEDs, and can put my ear next to the case and only hear the fan.

Re: {990FXA GD-80 v2} Phase LED noise question

Hmm i dont mean to HI-Jack a thread, but i didnt know the lights were meant to go on an off ? .. my lights above the ram all stay permanently on .. is that a good or bad thing ? .. also there is no noise coming from mine.

well if i have a computer with Phases i do not like the frequancy to bounce around through states so i make it so its at full Phase all the time from a few seconds after boot as i disable all power savings options (i do not care about saving money on my bill so i hate power saving features as they just annoy me)
if you have C&Q or any other power saving features on it will be very erratic, as for the phases increasing when you type that is normal because your drivers are dumping computations for the inputs into the CPU so it spools up to decipher the data and send it into the I/O on the board to go on its way (same thing for your browser as that is then running a EXE that is a compressed archive that needs to be decrypted as it opens using the CPU so it runs at full speed as its under load at that point)!
so nothing your reporting sound wrong with whats happening!
(open task manager and see what your CPU is doing to understand why its jumping around alot) (the CPU Phase lights were suppose to just let you know at what strength level your CPU was currently in - load effects the Phases as it actually ramping up the clocks in bursts when any program or load is being applied so more Phases are brought online to prevent instability happening as the CPU is increasing its clocks to stop it choking)
as you have had no BSOD's or crashes it all sounds like it functioning correctly!

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.

Phase LEDs won't go to max anymore

I used to have the phase LEDs vary from 1 (if idling in windows) to 5 (if I had all 8 cores working hard - using BOINC for example). I had a problem with my Radeon graphics card (a very fast one) so removed it and put in an older geforce. This was very sluggish when all cores were busy and 3 phase LEDs were lit always whether it was processing or not. So I removed the card and got the fast radeon working again, but I'm still stuck with 3 (although occasionally 4 now) phase LEDs. I note the old geforce didn't have a PCI express power connector. It couldn't have overloaded the pci express slot could it? Damaged the phase controller? I do get 5 LEDs when the PC is switched on before the OS loads.

Quote
I've made the changes in the BIOS, and removed 3 memory sticks, and hey presto the phase lights behave correctly and windows is much more responsive!
A good start.

Why is it now not liking my faster settings?
Looking at your SPD profile, you will see that these are overclocked and overvolted 1333 chips ( 667 in the Max Bandwidth specs). The worst part is that they expect 1,9V to actually operate at 1600. This is way beyond the normal operating specs. All DDR3 boards are built to JEDEC standards which specifies 1,5V. Overclocked mem modules on most Intel boards can accommodate up to 1,65V. Thus if these modules actually applied 1,9V in the BIOS you ran the risk of damaging your CPU's integrated memory controller. Lets assume that did not happen, but it is not inconceivable.
Quote
The faster settings were not actually made by me anyway! They are the BIOS defaults!!!! I had to manually slow it down to change to what you suggested.
We don't know if you enabled XMP or not. If you did, it probably applied the XMP profile. Applied DRAM voltage remains a mystery for now.
If your PC behaves normal at the 1066 settings, then add the other 3 modules and retest. You should even be able to run at 1333 8.8.8.23 according to the SPD, but once you decide to go there, first set the timings to 9.9.9.24 for a start and testing, before applying tighter timings.
A stable system at 1066/1333 is the main concern for now.
If ever you want to OC your RAM get other modules that can do it at 1,5V or max 1,65V.

X58 Pro Phase LED Question

Hey all,
I had a question about the CPU Phase LED's that I was hoping someone would be able to answer. As the subject line states, I have the MSI X58 Pro motherboard. The i7 920 is OC'd to 3.96ghz with the usual throttling features disabled in the BIOS. My question relates to the CPU Phase LED's. They were previously all on, no automatic phase switching but I just recently noticed that the left-most (2) LED's are flashing?!?! According to the manual, those are for "Phase 2 Power Mode". The other 3 LED's are lit continuously. What gives? What is that telling me? I thought that I had disabled throttling so they should be on all the time, right? Anybody know why? Thanks for any assistance!

mine's all lit, running at stock speeds... don't have any idea what this "phasing" all about. <a href="http://www.sweetim.com/s.asp?im=gen&lpver=3&ref=11" target="_blank"><img src="http://content.sweetim.com/sim/cpie/emoticons/0002041D.gif" border="0" title="Click to get more." >[/url]

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-GD65 Power Phase LED Question

I had a question regarding both the power phase LEDs and the actual power phases themselves.
I noticed that the power phase LEDs light up and change according to the currently active power phase for the CPU based upon load using stock settings.
However, when I applied a mild overclock, increase the bclk from 133 to 160, the power phase LEDs stopped changing. They are all lit all the time. Does this mean the power phase is not changing, so I am losing the power savings benefit? Or is the power phase still dynamic, it just stops registering and reporting with the LEDs?
With the mild overclock applied and all power phase LEDs lit up, in BIOS under the green powere menu, I can see the efficiency number fluctuating, which makes me think the dynamic power phase is still in effect.
Does anyone have any insight into this?
Thanks,
--MrAnt--

The interesting thing I noticed, is that apparently APS worked with overclocking enabled in older BIOS versions. I am running BIOS v1.5, I know current is v1.8. Can anyone confirm whether or not APS is enabled with overclocking in BIOS v1.8?
I do not have MSI Control Center installed, but I will do that as soon as I can to see if I can re-enable the LEDs and check if APS is working or not.
If APS is working just fine and it is only the LED display that is broken, I have no problem with that. I actually would like the LEDs turned off, but I want to confirm that APS is working before I do.

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

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?

Help with motherboard cpu phase leds.

i had to turn off c1e and c states to stop a high pitch whine that my pc was making but i noticed that ever since i turned then off only the first light stays sold and the other dont flash anymore.i also checked bios and the option for motherboard leds is on.so i was wondering does turning those two off also turn off the lights?

You mean the LED above the memory slots?
It's CPU_PHASE LEDs.
These LEDs will change according to CPU loading. The higher the power phase number,
the more reliable the power flow to the processor.
It should be normal turning off c1e and c-states will also turning off the lights, no need to worry.
yes those are the light i meant.i just didnt kno if it was turning off because of the settings i turned off or a defect.

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,

In case your problem boils down to a CPU that is not supported, there is no point in returning it to the reseller. He will test the board and probably find out that it works just fine once a proper processor is installed.

P55-GD65 Wont start Phase 4 LED wont come on

I just got a P55-GD65 and i got every thing on i have to say my PSU isint very good but i want to make sure that its a PSU problem before i go out bouying a 120$ PSU. The components are 2x2GB 2000MHZ OCZ memorys, an HD 4850 as video card and a i5 as the CPU, when i turn on it starts all the Phase LED's go on except for the Phase 4 LED, at first i tought it was a memory problem, i solved it puting both memorys in the black slot and it stoped beeping 3 times. but now it just turns on, all the leds go on except for the 4 phase led and after 4 seconds it goes off agian and goes back on and keeps doing the same thing over and over agian( going on and off on and off).... can someone help me ???!? its not the video card i tested it in a friends pc, might be memory havent tested it cuz i dont have another DDR3 supporting mobo.. PLZ HELP! im going crazy!! plz someone tell me its PSU!!!!
PS i tryd it with a 450 wats Seventeam PSU

You have inserted ur RAM on the very first slot (The blue one) right?? ...... Insert that in the first black slot on left side, thats the 1DIMM slot..... If you wanna use ur 2nd ram as well, then insert that in the 2nd black slot.... I don't think its ur PSU.

Aha! I did plug in the video card, but it seems I hadn't seated the connection correctly. Everything boots fine now, thanks!
However, I'm having another problem. It seems like the OS (Win 7) isn't recognizing the PCI slot, which is where my wireless card is installed. (At the same time Windows can't find an ethernet controller driver.)
Is this likely a hardware issue, or the OS?
