MSI Z77a G43 boot loop

Hi,
I have read all issues about boot loop problems, but nothing fit mine.
I bought MB MS Z77A G43 and Core i5 3570K. After building it, the computer is restarting again again.
I clear the CMOS, boot and in the monitor it says, that setting was reset to default, it shows my CPU,RAM,HDD etc. and it gives me 2 choices:
1) Press F1 to run setup
2) Press F2 to continue.
I tries several times both option, but after pressing the button F1 or F2, the computer starts to boot loop again. I cant go to the bios. Dont know if the problem is CPU or MB. I tried another power supply, but it didnt solve it. Any ideas?
Thx for helping

Hello again,
I have change CPU and MB for the new ones, but problem still occurs. I found an information on the web, that i5 3570k supports only RAM with power consumption max 1.5V. I have Zeppelin DDR3 4GB kit (2x2GB) 1600Mhz, but when I clear the CMOS and boot, the MB says that I have only 1333Mhz. That means the RAMS has more then 1.5V?
What do u think? The problem is RAM, which are not supported by CPU?

MSI Z77A G45 boot loop

Hi everyone!
I just tried to flash my MSI Z77A G45 today from the bios version 2.1 to 2.A.
I had blackscreens all the time when i tried to flash it with the M-FLASH utility from my bios.
Then everything just started normaly (after each blackscreen), but there wasn't any update, i tried to force the update with LiveUpdate.
And now when i try to start the computer, i just get a blackscreen (no signal for the monitor) and a boot loop.
It just stops and reboot after 10s.
My hardware is working perfectly, i think this is from a corrupted bios issue.
Which things i tried:
- Doing a clear CMOS (nothing happens)
- Removing the CMOS battery for 10 minutes (the reboot loop stopped, but there was not any display, i restarted the PC then and the reboot loop started again)
- Cleaning my PC (from dust and things like that), it was not efficient at all
- Booting from a USB key with the bios in, and formated as FAT32, nothing happens too. It doesn't recognize the USB key and anything else (keypad etc.) so the blackscreen was there again.
My Hardware:
CPU: Intel Core i5 3570 3.4 Ghz
Motherboard: MSI Z77A G45
GPU: None (Intel graphics 4000)
RAM: 2x4Gb Corsair Vengeance
HDD: Crucial M4 SSD 64Gb
Power supply: Corsair 850W
Do you think that i need to send my mother board back to the RMA?
I hope you will be able to help me, or find a solution
Thanks in advance

You can try the steps found here https://forum-en.msi.com/index.php?topic=119375.0
Otherwise, it is RMA time.
Next time use the forum flash tool and archives found on the forums.

MSI Z77A-G45 Boot Loop problem

Hi,
I recently built my computer 2-3 months ago. It worked fine until a couple days ago it started boot looping. It doesn't even get to BIOS. I think it's my motherboard gone bad. I switched CPU and memory with another computer and it works fine but when i put it in my computer it boot loops again. before i go through this whole warranty ordeal does anyone have any ideas i could try? Thanks!

>>Posting Guide<< please list all the components in your system!
Motherboard?
CPU?
RAM?
GPU (if you have a dedicated graphics card)?
PSU (Power Supply Unit - please list the +12v rail/s amperage rating/s on its data sheet)?
what you have described is usually either a Bad Motherboard or a Inadequate/overstressed PSU! so the components list of what you used to build the system is Very important to determine what exactly has gone wrong.

Re: MSI Z77A-GD65 Boot loop

ok then if you have tried other memory then its either the CPU (its not impossible and i have seen 5-6 dead CPU's recently) or Motherboard that has failed and both are possible! (unless you can test one of the 2 you have to blindly either get a RMA on ...

Black screen at boot MSI Z77A-G43 with HD7850

Hi,
I've tried everything You suggested in this topic. I've upgrade and downgrade bios (official 2.3, 2.4, 2.8, 2,9 / beta 256, 281,296) few times but still is black screen at boot. Now i'm on the newest beta bios 296 and still same issue on Sapphire HD 7850 with my Z77a-G43 board. I know for sure that sapphire working well because I've checked on other mobo with even worst PSU (400W instead 550W Volcano). Before hd 7850 I had gtx460 and swith those few times and always gtx460 works fine, so I don't understand anything right now.
Tried different slots, also clear cmos.

Do you see the same problem on bios 2.90?
The Z77A-G43 seems the have difficulties accepting HD7xxx AMD VGA cards lately.
It seems that the problem is gone. I thought of it being an ATI driver issue ~ but not even the latest didn't fix it. But since I flashed to BIOS 2.9 I haven't encountered the problem anymore. So I believe something is fixed between 2.3 to 2.9.
However my problem was a bit different that the OP has.
Oh, and I said this on other thread so I say it here too: MSI and Asus 7xxx cards haven't faced the kind of issues Sapphires are having. I'm so glad to my choice... as I almost picked Sapphire but then read comments on Newegg which weren't in favor for Sapphire.

Three beeps when booting new computer with MSI Z77A-G43 Mobo

I just built this pc and pressed the power button. Nothing happens for a few seconds and then I hear 3 beeps from the PC speaker. It powers off by itself and opens again, with 3 beeps again, and repeats this until i press the power button to close it down forcefully.

3 beeps is a memory failure!
try each stick in slot 2 individually as you may possibly have a bad stick?
if the first suggestion doesn't work remove the CPU and check the socket as you may have a bent pin in there causing the issue?

MSI Z77A-G43-memory problem

Hello
I bought lately new cpu,mb and memory. When i turned it on it was still rebooting after few seconds after start. So i treid to put just one memory in slot. It worked but only if memory is in bank 3 or 4. In 1,2 computer is still rebooting. Also it works with two memory modules, but putted in 3,4 slots only. And just in single channel. I saw that many people have the same problem and shop service wrote them that it works like that. First You put memory in slots 3,4 and then in 1,2. It is strange for me. I don't have two another memory modules to check if this is true and I want to that it works in dual channel, not single. So, is this true or mb is broken?

Hello. I have the same problem, except, I use 4 Dimms in 4 slots on my MSI board. I installed speaker on MB to see if there are any beep sounds during the booting, but all seems ok. The problem is the PC keeps still rebooting after about 5 sec. from the start. There aren´t any visual information on screen, since the start is so short. I tried to install dimms in 2nd and 4th slot first. Then to 1st and 3rd. In both cases the problem was still the same. When I put all rams in all 4 slots, the result is the same (restart for ethernity). The only way that goes is the PC runs with only 1 dimm in either 1st or 2nd slot. I tested all the memory modules and all of them work fine. I even tried this on a differennt mainboard from ASUS P8Z77-V LX. Now I tested it on MSI Z77A-G43. Both mainboards are new. There is a very slim change that both of them would be defective. Before I got MSI MB, I ran couple of days on the ASUS MB and everything was perfect, so I don´t think that CPU is defective. I even ran a few benchmarks on it. But I still don´t understand why can´t I run the system with all 16 GB of RAM instead of 4 GB in one slot. Please help me.

MSI Z77A-G43 and mixed drive types

Hi,
I have an own-built desktop using a MSI Z77A-G43 motherboard. The OS boots from an SSD but all documents, media, etc, are stored on 2x1TB HDDs, configured as RAID.
However, having performed a benchmark on my SSD I'm finding that it's speed is half what it should be. It's connected to the SATA 3 connector on the MB.
I'm wondering if the issue is that, because of the RAID drives, I have the SATA mode as RAID in the BIOS. Is it falling back to IDE for non-RAID drives? Is there a way to force it to use AHCI?
Any thoughts/help on this would be greatly appreciated.
David.

Well, checking you manual will clear up your confusion. SATA 3 is the connector number while SATA III is a terminology for SATA 6GB/s. Some say just SATA 3 meaning SATA III but that's just wrong terminology. The SATA 3 connector and all others but SATA 1 & 2 are 3GB/s (1-22 of the manual by the way)

MSI Z77A-G43 - extreme memory profile problem

Hello everyone,
I’d really appreciate a piece of help here. I’ve bought the MSI motherboard MSI Z77A-G43 and currently I’m having problems with my memory (slots 1 and 3). My PC has following specs:
-   MSI Z77A-G43
-   Intel Core i5 2500K (not overclocked)
-   RAM Patriot 2x4GB DDR3 1600MHz CL9 (PGD38G1600ELK) G2 Series
Everything is set to default values and works fine. But when I enter the BIOS, I see that the memory is automatically set to 1333 MHz. The memory has the XPM. But when I set the XPM (agressive timing, 1600 MHz) support (no other changes) and reboot the PC, it doesn’t work (endless reboot looping). Is there any way how I can make the XPM modus work? The memory is OK (tried on other MBs, XPM without problems), the CPU too. I tried overclocking, with slightly increased voltage I can easily reach 4,8 GHz on CPU, basically everything else is fine. The PSU is also sufficient (700W, OCZ). I can too set the memory on 1600 MHz manually, but the timing isn’t that good.
It’s actually a failure I can live with, but since it’s a brand new PC, I’d like to get the best out of it.
Many thanks
V.K.

Sometimes manually setting them works when XMP refuses to.
I don't know what the XMP SPD profile for that memory is, and a screenshot of your SPD and memory tabs would help.
However try the following.
Disable XMP and reboot so they are back at 1333.
Manually set it to 1600 and ensure manual setting of the timings to 9.9.9.24 see if that works.
If not set your DRAM voltage to 1,575V and see if that works.
It may be that your memory requires 1,65V, in which case, that is what you have to set. You should be able to see that in CPU-Z SPD tab under the XMP profile column.

Can i crossfire two radeon 7950's with msi Z77A-G43

Im looking to buy MSI's version of the Radeon 7950 twin Frozr to complete my system but im not sure if i will eventually be able to crossfire two of these cards in the future. I know that this MB only has one PCIe3 slots. Does this matter in crossfire? or will I have to replace the MB in order to corssfire?
MSI Z77A-G43
8gb Corsair Vengence
600 Watt Corsair PSU
Intel Core i5 3770k Oc's at 4.2 ghz
500 gb Western Digital HDD
Cooler Master hyper EVO 212

that should work but at PCI-E REV 2.0 speeds just make sure you have gen 3 support turned off or it will not allow crossfire!

I bought a MSI Z77A-G43 and 1st PCIE(3.0 I guess) slot doesn't work?

I bought a MSI Z77A-G43 and 1st PCIE (3.0 I guess) slot doesn't work? I mean when I put my gf card in it , my screen wont start. BUt when I put it to other blue Pcie (2.0 I guess) it works. What will be the reason? Do I need to do anything in bios ?

I had a similar situation recently.
1.) Check the cpu/ socket for damage
2.) Remove the mobo and make sure there are no extra stand off's under the board.
3.) Check the pci/e slot for obstruciton or debris
Other than that it's probably going to be an rma issue.

MSI Z77A-G43 GAMING LGA 1155 MOTHERBOARD

Does anyone know where I can get one of these in the UK, everywhere I look it says out of stock/discontinued..... I mean everywhere
I have no choice to get a z77 version of the motherboard as im running an i5 3350p ivy bridge which is a 1155 socket.
any help or location of this product would help.... I wish MSI would just sell their stuff too.

was easy as just typing it in on amazon enjoy!!!!
Thanks for the reply I did see that one but I was looking for the red and black dragon emblem one, its seem everyone of these I find is somehow discontinued.
prefer the red and black as its goes with the colours scheme I have also matches the 2 msi GPU's I have, just wondered if anyone knows of a UK retailers of this version
As a side note the blue and black doesnt look as impressive XD

MSI Z77A-G43 UEFI Overvolt+Intel Exteme Tuner Overvolt combo

Hey all,
I just wanted to run past you an experiment I did and I think worked.
I currently overclock my i5-3570k with an every day overclock of 4.4 at no offset voltage and a benchmark overclock of 4.7 at +.14V - however my benchmark overclock isnt exactly stable.
I noticed in Exteme Intel Tuning Utility There's a slider there for additional mV turbo voltage. I'm multiplier overclocking for my benchmark overclock with no power saving features and my voltage tops out at around 1.34V but when I add additional mV on Intel Extreme Tuner it goes to 1.38V. It also made me pass my 3dmark at 4.7 which is hit-or-miss but now worked every single time and also passed IBT.
Could this truly be modifying my input voltage on the CPU beyond the motherboard's limited offset mV overclocking?
Is this super dangerous and should I never do it again?
thoughts/opinions
also obligatory 3dmark link

1.400v's on the CPU is the industry recommended limit for an everyday machine, so whatever way it gets there shouldn't make any difference.

If not doing a 'Turbo' OC, I don't see the connection with mV turbo setting. If raising the mV on the Intel utility raises the voltage to the CPU, and it is confirmed, then it must work as you have described.
