Z77 mpower mainboard giving me a code FF, but only sometimes?

I've just built my new PC and it's working almost perfectly except that sometimes when I switch it on all I get is code FF. But trying it again and it will come back as normal and give me no problems at all
I understand from reading posts that it's to do with the CPU and bent pins or an over-tightened heat-sink, but I've checked the board and cpu twice now with a magnifying glass and I can't see any problems in that regards. I've also tried adjusting the heat sink tightness. But I'm still getting this error, probably about 5 times out 10.
Main system specs are;
Intel i7 3.50Ghz 3770k idle temp is 34C
MSI Z77 MPower (MS-7751) updated to the latest BIOS
2x 8GB Kingston HyperX Blue dual channel DDR3 DIMMs @1600Mhz
Gigabyte GTX760 OC
Windows 64bit Ultimate on Toshiba 128GB SSD
My thinking is that it's a MB fault rather than the CPU due to it working perfectly once I get it to boot.
Any help would be greatly appreciated.

My best guess is the PSU may be going flaky. Double check all the connections, especially the JPWR2. What is the PSU by the way? Model, brand, specs, etc..
Hi, thanks for the response,
I've got an older model Enermax Galaxy 1000w modular PSU with two 12v CPU connections, 1 is an 8 pin the other is two 4 pins that can be connected together to make an 8 pin. I have tried both leads but get the same results. All connections are fully clicked in place. Hope it's not the PSU but I'll try a feed via the molex connector and see if that helps

Z77 MPOWER stuck at A2 fault code

Hello!
Ive been working on this issue since yesterday morning and thought I would post here to see if the is a simple solution I am missing.
Completed the build about 4 months ago. Have had no problems. Computer was running fine, then it was left over night and it restarted and froze seconds into the boot showing A2 in the lower right hand corner of the screen. (it also reads on the motherboard LED panel) It is not finishing Post, entering BIOS or OS
What I've tried so far:
1 Cleared CMOS via button on back. got to a screen that said everything had been reset to default values and to press f1 to set up or f2 to continue. When I press F1 it says "entering Setup..." on the bottom of the screen but goes no further. Sometimes the computer shuts off then comes back on, once back on it stops at displaying A2 on the screen. When I press f2 nothing happens.
2 Tried switching to other BIOS with MULTI-BIOS switch, Same issue.
3 I got a wired keyboard to make sure it was getting a signal. Issue remains.
4 I unplugged everything except Ram, PSU, GPU, CPU. Issue remains
5 got a PSU tester, tested the PSU-was bad- so I replaced it. Issue remains.
6 Read that A2 was a VGA fault-Tried with onboard video. Bought a cheap Video card to see if that would work, Issue remains.
7 created bootable Bios memory card using tool from this forum and could not get it to boot from The thumb drive.
Any ideas?
System
Z77 MPOWER motherboard
Intel 3770K i7 processor stock cooler
Evga Geforce GTX 660 ti
Corsair 16 GB DDR3 1600
Antec HCG-750 psu (replaced the Cougar CMX 1000w)
1 & 2 TB HHD for data and media
228gb SSD for boot and data
PCI-e USB 3.0
Any suggestions would be super.
Tim

Here is the list of codes;
http://www.ami.com/support/doc/AMI_Aptio_4.x_Status_Codes_PUB.pdf
0xA2 IDE Detect It's got nothing to do with VGA.
Use just one of the RAM sticks in the primary DIMM slot for testing (DIMM2). Clear CMOS again, PSU power cord removed, battery removed. Was this a migrated OS or fresh install? Z77 defaults to AHCI Mode, if the OS was originally installed under IDE, it will not boot.
A2 may be a failed HDD/SSD.
Added: We have seen it many times that a PSU may even pass a test but still be faulty. Just saw it here at the forum yesterday. Exactly what did you replace the failed PSU with? Brand and specifications please. Cougar 1000 in your sig? I will look up specs for it.
2nd add: Not too impressed with that multi +12v rail design. +12V1@24A, +12V2@24A, +12V3@24A, +12V4@24A, +12V5@28A, +12V6@28A
This suggestion would be plenty of power for your system configuration and much better being a +12v single rail model;
>> TX750 V2 <<
Best troubleshooting thought I have is it is a failed SSD that has the OS on it.

MSI Z77 MPower - Boot issues (A2 debug code and more)

Hey guys,
I've been trying to get my new computer build working but I have encountered several issues when trying to boot the computer.
Before putting everything inside my case, I tested the motherboard + CPU + 1 stick of ram to make sure everything was working. I had issues in the past where I had to remove everything once I had things mounted.
Everything seemed to work and I got into the BIOS and looked like everything was good.
I mounted it in the case with the same configuration and I was able to get into the BIOS again. So I thought everything must be ok.
Fast forward a couple hours later after I finish plugging everything in, I try to turn it on but it just gets into this boot loop.
Turn on > Fans spin for a couple seconds > turns off > repeat. This just kept going on and on and I wasn't exactly sure what was going on.
I started to unplug components and when I only had the Mobo + CPU + 2 sticks of ram in I was able to get into the BIOS.
I plugged things in one at a time and when I plugged in my SSD it would work.. but when I added another drive I would start getting the A2 Debug message on my board.
I would continually get this A2 debug message and I am not sure what to do to get it to work.
I have updated my BIOS to the latest ones and it is still not working.
Could this be an issue with my PSU? I really hope it's not the MOBO..
My System:
i7 3770k
CoolerMaster 212 Evo
MSI M77 MPower
16GB DDR3 Ram
7870PCS+ Tahiti LE
Corsair HX650 PSU

Quote
I've tested it with one stick and 2 SSDs and it doesn't give me the A2 debug code.
Do you have any different ram to test with?
What ram exactly are you using?
You may perhaps be able to set the ram timings in bios to JEDEC standard 9-9-9-24 1600 perhaps

Z77 mpower debug code 62

hi everybody,
i have this motherboard for a few weeks now.and recently it will not boot, but give a error code 62 ,
fans will be spinning etc, but no post.
i have noticed loads of other users having this same issue from different websites, and i can not pin point the problem,
i still do not know what the error code means, as its not listed in the manual.
i am having this problem with intergrated graphics intel cpu. this happens when pc is switched off,not restart.its an intermitant issue,meaning it will work fine at times on boot,but not always,
i have to put pc off, and then it will boot up again fine. what is causing this issue on our z77 mpower boards ?
system specs :
no gpu ( using cpu gpraphics )
cpu i7 3770
mobo z77 mpower on bios version v17.11
psu seasonic 750w evo m12
2x 4 gigs ram
sata hard drives....
can anybody help ?

Quote from: badboy2k on 05-February-14, 15:18:43
if the CPU is seated badly it can cause the issue if its not contacting the pins properly in the socket!
ok, but the cpu can only fit one way tightly in socket, there's no movement or looseness when inserted.
whats strange is that this is a problem experienced by many, just google z77 mpower error 62
thnx for advise btw but i think its something else though any advise would help. i will reseat tonight.

MSI Z77 mpower fan controll

MB: MSI Z77 MPower
In bios the auto option is avaliable only for CPUFAN and SYSFAN1 SYSFAN2. At the same time in ControlCenter it is possible to enable System Smart fan controll for each fan.
Is there any way to save selected options in Controll Center and automaticly apply them on sturtup?

Hi
CC shows very first settings taken from BIOS. So whatever its set in BIOS, CC will show this by default. And sadly cannot be changed to be applied differently. Yet you can change settings in BIOS and you should not need to use CC for fan control.

MSI Z77 Mpower Code A0, and wi-fi not detected ...

Hello, from about 20 days I use the new mainboard MSI Z77 Mpower.
My system is composed as follows:
MSI Z77 Mpower, PC1500 DDR3 1866MHz 16GB Corsair Vengeance
1.5V CL9 (2x8GB), CPU Intel i5-3570K 3.4 GHz, SVGA ASUS GTX660 TI, Samsung SSD 128gb 840pro.
I installed windows8pro in UEFI mode with ssd disk partition gpt.
As bios setup is everything default except xmp profile enabled for the Rams, and UEFI boot-legacy because I have linux in another disc.
It all seems to work fine, but I have a few doubts_troubles !
1) Sometimes in debug LEDs, instead of the temperature appears the code A0 ... is it normal or it indicates a problem ?
2) I've never tried the Wi-Fi, it is normal that it only works if the LAN cable is disconnected ?
The problem I had with wi-fi is that sometimes the sistem said that the hardware was not found or not connected ... I tried to install the latest drivers without any success, after several attempts, I think I found the problem ...
Wi-Fi is connected to the mainboard, I think in the USB port, and for some reason it does not make contact, after pulling back slightly the 1 mm. module it started to work.
If instead I press slightly forward, (the pressure that normally is used to attach the antenna) it loses the link ... Do I have to leave it like this or can I do something to resolve the problem ?
3) Normally the steps to open and close the PC are very fast, in some cases, the PC takes a long time to shut down, and once gave me the same problem at the start, after a long wait I rebooted and it started without problems .. .
Normally, the computer is stable ... Do I have to try the thorough ram test ?
I apologize for being longwinded and thank you in advance for the answers.

The wifi adapter is removable?
In case it is, without losing the guarantee.
If you give me confirmation, I try to see if it is just a matter of contacts.
I need specific instructions!
for now it seems to work properly.
If ask rma, mainboard or complete one module wi-fi?
Wi-Fi, it is normal that it only works if the LAN cable is disconnected ?
Thanks pikka68
No, the adaptor isn't removable. Perhaps I misunderstood, you were saying that when you hook up the Ethernet cable, the mainboard shuts off the wifi. You can check in the bios for an option in regards to this or it could be the OS I am not sure. If they are both working when needed, is there really a problem?

Z77 MPOWER - Debug code A2

I've been using this motherboard for a solid month until last Saturday when I shut down my pc and I walk away being done for the day.
To my surprise the motherboard boots itself as I'm walking away and it's refusing to go post bios and keeps giving different error codes depending on what I pull out. Having switched all parts and taken everything out the only debug code that remains is A2.
Specs
Z77 MPOWER
3570 @ stock with h80 cooler
2 x 8 gig ram 1600
2x 7950 @ stock
2 ssd's, 1 hdd and 1 DVD drive.
Corsair ax 750.
What I've done.
Pull out memory cards 1 by 1.
Pull out the Graphic Card, tried different as well.
Pull out all SATA cables and connectors.
Pull out everything hooked to the backplate.
Reset CMOS (Will boot, when prompting to go into bios to change settings it will shut down and go back to A2)
Switch to DUAL BIOS (Will boot, when prompting to go into bios to change settings it will shut down and go back to A2)
I've RMA'd the motherboard but the shop said a pin was bend and refused to fix the motherboard. Having received the motherboard back and inspected the socket I did indeed notice a slightly bend pin.
However this pin is so slightly bend that it's not touching any of the other pins and it took me a "whole" 2 minutes to bend it back in line with the rest. Whatever this was caused by me or them I'm unsure, hell the pin is so slightly bend that I doubt it would interrupt with normal operating procedures.
The motherboard however is still not functioning and stuck on the A2 error code. The CPU debug leds show all lights as a "go"
I wonder if it's even possible for the pin to become damaged while in usage for over a month and cause it to be stuck at A2 debug code? Having looked up the code it seems related to SATA,IDE and the likes which where not plugged in.
I was forced to buy the same motherboard from another store to actually use my pc again, the CPU itself is working fine so it's definitely the motherboard. Love the mobo, just not the store support
Needless to say, having spend 360 (180x2) euro on this board and receiving virtually no support from the shop, I'm not amused.
Any support or advice on this matter would be greatly appreciated.
Many thanks in advance,

Quote from: badboy2k on 08-November-12, 01:50:54
ok have you asked to return the original board to the shop for RMA or a refund?
also did you have MSI live update installed when it all went bad?
I have returned the original board to the shop for RMA. They refused to accept it claiming MSI would not accept the board due to the slightly bend pin.
I did not have MSI live update installed at that time as I reformatted my pc recently so bare essentials were installed. I however do have it installed right now and used it update my new mobo to the latest bios firmware.

MSI Z77 Mpower error code "B2"

Hello,
I had just bought a Z77 MPOWER board to fit with my Core i7 -3770K.
When i try to boot i got the code error "b2" and nothing more...
Many people seems to had got the same problem, so i tried few "solutions".
When i downgrade my GPU card (7970 Radeon) to an old 8800 GTS, i can boot, but Keyboard and DVD and one of my HDDs are not activated (so i can't install MSI drivers from CD) the mouse works.
I had Already install the last BIOS from MSI support, that don't change anything.
I will be glad to get help , i barely going to send back all stuff to seller
and go back to Asus Board...
Thx for the help
Configuration:
Msi Z77 Mpower
Core i7-3770K
8 Go GSkill Sniper
7970 Twin FRoz GHZ edition
2 x 2to GREEN CAVIAR Sata III
1 X 1To BLUE CAVIAR Sata II
1 x 256 SSD OCZ Agility Sata II

thx for your advice always nice to get a good advice
but as i had repair the original PSU i will save few bucks and keep going with it.
i go sleep i pray for new idear about the "B2" problem.
in anyway i will be oblige to contact my seller , i only have 10 days to change the board if i can't solve the problem :(
Good night all.

Z77 mpower led error code 64 after long POST

Hey guys. I am new to this forum, But I have been having a frustrating issue with my new mpower board.
everything seems to be working fine... runs fine recognizes all of my hardware. plays games and the whole works. however there is one problem. the board takes forever to POST. it will stick on b4 on my screen and on the debug led with a 64, I looked in my manual and found that error code 64 means late CPU initialization. what does this mean I tested my ram by testing each stick in different dim slots and it makes no difference I tried putting my hdd's in different SATA ports and nothing changes. I am running the latest bios I checked. is this an issue I should be worrying about or being everything is running fine not to fuss about it? I just want to make sure everything is running like it should any help is much appreciated being my pc knowledge is limited.

the B4 is a USB hotplug issue. remove the front pannel USB 2.0 header connectors and see if that stops. if not remove 1 USB device at a time!
the 64 may be related to the USB hotplug issue and its stoping the CPU to hold the post till it leaves the USB and skips it.

Z77 MPOWER - Debug code 55

Hi I just finished building my new rig with a mpower Z77 booted it and all the fans spin up but then on the debug LED it shows code 55 then just reboots and keeps cycling like that till i pull the power.
Anyone got any ideas?
Case : Fractal Design Define R4
PSU : Corsair AX750
MotherBoard : MSI - Z77 MPOWER
CPU : Intel Core i5-3570K 3.40GHz (Ivy Bridge) Socket LGA1155
Memory : Corsair Vengeance 16GB (2x 8GB) [CML16GX3M2A1600C10]
VGA : MSI GTX 660 Ti Power Edition 2GB GDDR5

Got response from MSI this morning

For MSI bent socket pins aren’t a reason to declare the warranty void.
According to the serial number you sent me, your motherboard is still in warranty.
Please contact your reseller, Aria Technology, again to ask them to send your motherboard in for RMA Service, if necessary showing them this email.
If Aria Technology still won’t help you, please contact me again.
So have messaged Aria again, going to be interesting what they say.

All you can do is try with each stick of ram alone in DIMM 2 w/ a barebones set-up. (Only ram, PSU, CPU & Cooler)
Re-seating the CPU may help but since this occurred when overclocking / changing bios settings w/ no physical adjustment it doesn't seem like that would help.
Assuming it doesn't work either way as recommended above, I would rma the CPU & mainboard at the same time. It's likely one or the other.

Z77 Mpower boot issue - won't POST

Hi there
Got a question regarding a PC build that isn't working as well as hoped. Doing this on behalf of my friend but I've been helping him while he builds it so have a good idea of what's been going on.
Set up is as follows:
Processor: Core i5 3570k (stock, not overclocked or anything)
Motherboard: MSI Z77 Mpower
RAM: 8GB Corsair Vengeance memory (in 2x4gb)
PSU: Corsair 800W Gaming PSU
Storage: OCZ 240GB SSD
Cooling: Zalman water cooling (can't remember the exact model off hand I'm afraid, will try and get that later)
Graphics: HD 4000 integrated (for now, haven't got the graphics card yet)
We built the machine and got it going no problem. When it was first built it booted no problem, so we set up boot priorities and then installed the Windows 8 Enterprise 90 day trial. All good so far. Installed no problem at all at lightning speed and we got into Windows fine. Installed lots of drivers and so forth with no such trouble either. CPU was reporting a steady 25C average temperature on idle and everything seemed to be going smoothly.
Then we hit a stumbling block. We powered off the machine to make a minor adjustment in the case (all while static protected with a wristband), and after doing this we then powered the machine back on. We're now getting a dim red LED (almost seemed half powered) in the DrMOS overheat warning and then two bright blue LEDs next to it indicating the CPU power phase. The fans will spin and case LEDs come on, but nothing else happens other than that and the LEDs. No POST screen or anything like that. It might also be worth noting that now when you plug the computer in, the green LED on the internal power button no longer lights while the machine is off - when the machine was working it would.
I've spent hours trawling through the forums and can't seem to find the same problem happening. We're getting a bit worried that there could be a fault on the board but wondered if we could get some advice from here first. I tried resetting the CMOS with no avail and trying the other BIOS.
As a last resort, we've now removed the cooler and CPU to check the CPU hasn't melted or anything drastic like that and it's absolutely fine - no visible damage. We've left it like that for now until I can get back over there with some more thermal paste to reseat the processor and cooler so until then we're stuck anyway.
If anyone has any ideas or knows of the problem, it would be really appreciated as we're a bit worried! What should we try?
Thank you!

Many thanks, will give that a try. Is it an RMA to MSI if that fails then? Forgive me for not totally understanding consumer rights - but it was only bought around a week ago - could we get the supplier to exchange it or would it have to go to MSI for repair?
Quote from: xmad on 27-December-12, 05:16:31
Next, remove the main board and place it on a non-conductive surface and test it with a single stick of ram in dimm 2, cpu & cooler. You can try switching the ram ram sticks and dimms, but the last few times I saw anything about the drmos alarm it was a defective mainboard.
While it is out and the cpu is removed though, take a good look at the cpu socket pins and count all the stand off to make sure there are not extras.

Z77 Mpower & x16 SLI

Hi,
I'm running 2 x 670's on an Z77 Mpower mobo and the mainboard tab in CPU-Z is showing the cards running SLI in x8
What is all that about. I thought they are suppose to run in x16? How do I fix that?

no you are wrong as your 1155 socket CPU (as all have the same) has 16 PCI-E lanes total so x8/8x is normal for 2 cards as the board has no PLX lane splitters so can only use what PCI-E lanes the CPU has!

Z77 mpower mainboard giving me a code FF, but only sometimes?
