785GM-P45 noise from CPU APS LED

Hi, I am experiencing the same problem as https://forum-en.msi.com/index.php?action=printpage;topic=131620.0
I did a quick search online, and it seems to be a common problem with MSI motherboards. Is there any way to fix it? the high frequency noise is really annoying!

That may be an error showing support for those two 125W CPU's. If 125W/140W CPU's were actually supported then the others would be in the list list also and as you can see they are not. There are some other MB's that only show those two CPU's supported and not the other 125W. It would be best for you to check with MSI to confirm/deny 125W CPU support.

I contacted them using the link you mention. Their answer is really slow. Finally, I got their answer today. But there is nothing really helps.

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.

G72-b57cl notebook mic noise from CPU fan

g72-b57cl notebook mic noise from CPU fan
At first I bought this laptop, mic setting was disabled. I enabled this, and then I can't talk through the mic because of noice from CPU fan. how can I solve this problem?

See, I'm not entirely sure it's the fan. I can just hear it more easily the closer I get to the fan, which leads me to believe it's somewhere around there. As in, not the HDD on the other side of the computer, though I suppose it could feasibly be it. I also think I could have described the noise a bit better. It seems to sound like the CPU when it's under strain, but...not the same, I can't quite explain it. The computer will heat up and spin the fan independently of this. If it is the CPU or GPU, then I don't see what's generating this extra load separate from the nvidia-utils, which I already had earlier.

MSI z77A-G43 C1E enabled and strange noise from cpu area ?

MSI z77A-G43 C1E enabled and strange noise from cpu area ? What will be the problem? When I disabled it there is no sound. BUt when I enabled it there is a strange noise while moving my mouse cursor or when there is some CPU activity, sounds like a squeeking or scratching, a bit like hdd activity, but barely noticeable. It looks like it's coming from the area around the cpu socket, must be something on the motherboard. is there a solution other than just disabling it? I want to be able to make C1E enable but cant bare this noise so I have to turn it of....

Sound like some electrical sound produced by current going through that area.
Try contacting MSI support for more help.

Weird noise from CPU

A few nights ago I awoke to hear my P-book G4 making a loud crackling noise so I freaked out and shut it down. After restart the next day it booted fine and then just booted up to a blue screen. I Waited until today and I tried to reboot off of the startup disk, and it spit that out and then all of a sudden it restarted normally but made those crackling noises again. THe noises have now stopped and I am running disk utility on it to see if that helps but does anyone know anything about this issue and if so could I have some help. Thanks

Denny: Replace your hard drive. The optical drive can't possibly make crackling or grinding noises without a disc in it, and it can't slow the operation of the computer to a crawl or prevent a normal startup from the hard drive. A failing hard drive would account for all the symptoms you've experienced, including the awful noises. Replacing the HD is easy; instructions for doing so are right in your Powerbook owner's manual.
I hope all your data is backed up, because any grinding noises you've been hearing could have been the read-write heads in your hard drive plowing furrows into the surface of the platter where your data used to be. You'll be very, very lucky if you're able to recover everything important from that drive. The more you try to use it, the smaller your chances of salvaging anything from it will become.

Mac Pro 2010 and Lion: buzzing noise from CPU board when idle

Hi all,
I have a 2010 Mac Pro with the 3.2 GHz quad core. I recently installed Lion and now whenever the CPU load falls below a certain threshold (approx. 10-20%) something on the CPU board starts to make a buzzing noise. It sounds like a capacitor or coil. Sometimes it is nearly impossible to hear but most of the time it is quite annoying.
Removing the CPU board and putting it back in, solved it yesterday. But after waking up the system this morning, the buzz was back again.
Also, this does not happen when running Snow Leopard or Windows in Bootcamp.
Does anyone experience the same issue?
Best,
b.lam

Then I would do a clean Lion install. Hopefully you saved the installer DMG.

Quote from: gilbert1019 on 14-July-15, 07:07:03You can disable "INTEL Speedstep" feature in BIOS and see if that would make the symptom disappear.
Sorry, I confused sides. It is actually coming from GPU area...

Alert from CPU led

Can someone tell me why my Macbook pro 13 inch Machine keeps saying Alert From Cpu LED on boot up?
I still have 110 gigs free space left on my hard drive..
Thank You

That question would be better asked/answered by someone at Symantec as they are the makers of Norton Internet Security.

GE70 2PE Buzzlike noise from Fan/CPU area

Greetings fellow dragon army. My newly bought(been 3 weeks or so) has started to create excessive buzzlike noise from the fan as if theres a little string hitting the fan while its working especially when turbo boost is on making it very very annoying but also making me troubled. I've not hit the laptop to any surfice and theres no problem whatsoever affecting the performence at all. Any ideas what might cause this?
Thank you for your replies, Have a good day.
Best regards, Berkcan.

this could be a defect fan where fan is spinning right but making a noise unless it's from speakers.

P67A-GD53 stuck in APS LED 1, No Beep and Black Screen

Hi,
I just got my full new gaming Pc, I mount all component and when I press PWR Button, fans, leds, GPU, HDD and all items switch on, but my APS led 1 stuck in LED 1, no beeps black screen, and it can stay all night on without changing...
My Components:
MOBO: P67A-GD53
CPU: Intel 3rd Generation Core i5-3570K CPU (4 x 3.40GHz, Ivy Bridge, Socket 1155, 6Mb L3 Cache, Intel Turbo Boost Technology 2.0)
GPU: Asus nVIDIA 3D GeForce GTX 560 TI DirectCu II TOP Graphics Card (1GB)
PSU: Corsair CMPSU-700GUK Gaming Series GS700 High Performance 700W Power Supply
RAM: Corsair CMZ8GX3M2A1600C9 8GB 1600MHz CL9 DDR3 Vengeance Memory Two Module Kit
I read some things over internet and they say lot of things, I have some ideas, Maybe PSU (My CPU fan stops at 5 seconds after power on, that's normal?), maybe corrupted MOBO or maybe CPU.
Any suggestions are
Thanks, and sorry for my bad English

Quote from: XFM on 13-September-12, 17:00:14
I know for sure you will have more questions when you get the Z77 but one thing is when you do get it is don't assemble it in the case right away. Do initial assembly outside the case with MB on a sheet of plain brown cardboard or on a cardboard box. That will save you time and extra work until you get it running properly.
One hint now is for initial start up use only 1 stick of RAM in the black slot nearest the CPU, do not put all of the sticks in right away. Also take note that the green LAN LED will probably not light up on the first start up, that's normal and will be OK after it is started a 2nd time. That will happen every time you remove power from the MB such as unplugging PSU or turning off the PSU switch. We'll be here waiting for you to answer any more questions you may have.
Thanks for the information!
It will arrive tomorrow, I will tell you how is it going.
Greetings

Unlocking cores on 785GM-P45

i'm trying to unlock 2 different Phenom II X2 560 BE on 2 different 785GM-P45 boards but am running into trouble. im following the standard guide (https://forum-en.msi.com/index.php?topic=132314.0) but when i select cpu core control, i only see the option for Core 1 and Core 2.
I am using the latest BIOS.
Does anyone know how to get this working?

after enable the Unlock CPU Core function and Enable the ACC (Advanced Clock Calibration) function, you leave the core control to auto. reboot and see if it is stable. if not stable, come back to bios, and set core control to manual, try to disable one of core 3, and core4. if stable, you get a good X3. if still not stable, then you cpu is still a good x2.

785GM-P45 16gb issue

I have installed 4 4gb corsair dual ram sticks 1333mhz in my pc (785GM-P45) but after maxing 16gb I am having issues with extracting files, as soon as I take out 1 ram stick everything is ok, can anyone share some light on my problem, I have updated to the latest bios & I am running an AMD Phenom II X4 945 cpu 2200mhz, 4core processor:confused2:

with 4x sticks you may need to drop memory freq. to 1066MHz and also ensure that you use 2T

NF750-G55 won't power up, almost no APS LEDs activity

Hi there,
Just purchased a brand-new NF750-G55 mobo and a Phenom II X3 720.
Installed mobo, cpu, stock heatsink and thermal compound, ram, psu and monitor only. Everything is powering up properly, shutting down, plugging everything in the case, with drives, gfx card... Power-on the computer with no problem, start a Win7 installation, and I leave when Windows disk is copying data.
When I come back a half an hour later, the computer is off. Pushing the on/off button leads to the power led to blink every second without stopping until I unplug the power cable.
Checking mobo, when I push the power-on button, the 1st of the 4 APS LEDs lights blue for half a sec and instantly powers off. Then nothing will even happen, even when pushing the power button again. Have to power off/unplug the psu and power back on to see the same thing happening.
Switched ram, psu, removed everything but cpu and heatsink (actually removed the cpu, cleaned it, applied thermal compount again...)...and ultimately, removed mobo from the case, nothing will work. The power button on the mobo lights up but won't power on the computer, and the heatsink won't even start working.
With I had a spare AMx mobo and a spare CPU and heatsink, but it's not the case, so I can't cross test...
Removing the cmos battery didn't help either...
Also, no beeps at all. And CPU looks perfectly fine, no bent pins, and put and removed from socket without any difficulty.
So, what do you guys think?
Thx!
edit: seen on another topic:

I found it on standby with the power LED flashing but it would not restart. Just the blue LEDs for <0.5 secs. I even reset the BIOS.
Could there be an Electrical Overstress on mboard damaging CPU?
Quote from: Bas on 29-July-11, 18:18:40
Could be 2 things: 1 PSU underpowered or broken (or both)...2 CPU overheating (something wrong with the heatspreader of cooler).
The blinking led shows it did an emergency shutdown to prevent damage.
I already tried with 4 different PSUs, Antec, CM, Corsair and OCZ, from 450 to 600W. All had the exact same behavior. So what is this freaking emergency shutdown caused by? Tried with Kingston and Patriot ram, so the only parts that haven't been cross tested are the mobo, the cpu and the heatsink...but again, it worked well for half an hour!

I have seen thousands of boards myself, but can still count the bad ones on two hands.
(if you forget the bad-desinged ones, but those show up in the forum in big numbers, like the last Intel 67 series before B3)
Me too, 2 bad boards in a year probably makes 2011 the worst year since I built my first computer back in '98. And unfortunately, these two boards are the same brand...
Quote from: Fredrik on 07-November-11, 22:08:19
It worked till you put it in the case. User related. Probably a stand-off too many and/or motherboard under-side got scratched in the procedure.
nope...check my writing again: worked for 10min out of the case, then for an hour into the case. THEN it stopped working.

Bizarre High-pitched noise from K8N-NEO *I have read the other posts*

Hello.
I just got a new system to build, but it has decided to pee in my Wheaties.
Here are the specs:
MSI Neo Platinum
Nvidia 6800 video
Athlon64 3200
Kingston Hyperx PC3200
Antec Tru430 - 430watt
+5 +12 +3
36A 26A 28A
The board, CPU, memory, and video are installed in a new Antec case. The CPU is installed properly and I am using some ArticSilver 5 paste.
When the board posts, I hear a horribly loud and high pitched squeal. It sounds like a smoke detector going off.
I have read a number of posts regarding loud noise from the MOSFETS or from a loose chipset heatsink or as a result of a poor power supply. I think that this power supply should be adequate and the noise seems to be too loud to be a result of a loose component.
The board appears to go through the post procedure and stops on the "processor initialization" stage. After about 2 seconds of being powered on the video fans stops spinning. The HS Fan (which is the one that came with the retail package) does not appear to be spinning at full speed, neither is it running too slowly. As a result, I have not put power to the board for more than a few seconds (fear of heat damage, though the HS never gets warm...)
I am at a loss here. I have reseated everything several times, if this is a defective board then I am really irritated that it would pass QA and be sold. Any suggestions that you could provide will be greatly appreciated. If you prefer you can send me an email at [email protected]
Thanks again!
Moe

Cheers !

Constant Fan Noise from Hard Drive

My power book runs with a constant 'fan' like noise from the hard drive (front left of pd)
My friend has same machine and has No sound,
checked with display models in Apple Store (ear right necxt to pb) - No sound
I have had this low level noise from new.
Anyone else have the same problem.
John

hello there!
When I upgraded to 1.4.0 and I notice that ear piercing noise and it was quite annoying. I called Apple and they advised me to look into the activity monitor. And YES, it ws the anti virus that came with .mac that 1.4.2 for some reason did not like and the process was running for such a long time consuming the resources including of course HD. I removed the anti virus (which at this point was useless) and the machine was just wonderful again.
I think what I may say is that you may want to look for a process (using the activity monitor) which is eating the cpu alive - if you can remove it the better, else try to deal with. Good luck - an OSX convert!
