Hello all,
I have this weird issue with cold booting while overclocking. I've tried very hard to diagnose the problem but have been unable to find the culprit.
So I'm using an i5-2500k with the mobo in the subject. I have flashed the BIOS to the latest (2.4). So everytime I try to overclock by using a different multi (it can be as subtle has x34) the system will fail the overclock while cold booting. What I mean by that is if I do the overclock from the bios then save&reboot it will load in windows and be totally stable under IBT. I can achieve any kind of overclock up to 4.7 Ghz and it will be totally stable.
BUT, as soon as I do a shutdown of the system, upon booting (cold boot), the computer will try to boot but fail at it. I'll be prompted by the bios to reload default.
I've tried various combinaisons to no avail. I even tried to underclock the processor to sub x33. I don't understand what could be wrong. It seems as soon as I switch to anything else then auto on the ratio, it won't boot from shutdown. Weird.
Thanks in advance for your inputs.

As you know I got exactly the same issue, but mine does boot when manually set at a lower ratio.

  • MOVED: Z77A-G43 no SpeedStep with manually set multiplier

    This topic has been moved to Overclocking, Undervolting.
    https://forum-en.msi.com/index.php?topic=165305.0

    I was told that Z77A-G43 should be just fine for my needs. Couple years ago I bought high end MB and it was a mistake, they are putting there so many useless stuff for which I need to pay ... (like firewire which I never used).
    Z77A-G43 is fine for me but I was not aware before buying about all of its limitations. It is quite ok now when I figured out in UEFI where the needed options are hidden. Probably on better board I would be able to get from 200 to 400 Mhz more from CPU but to do that I would need to take off the IHS and pay almost 2 times more for the motherboard. (and pay for useless stuff like two quick PCIE ports (I am not planning to have a SLI/Crossfire), dozens of SATA ports etc.) If there were good board in decent price I would bought it but I do not need a motherboard for a homemade datacenter
    Regarding Lucid earlier I had Abit (also the lower end) and I am not used to be virtually limited by having minimazed bios options or lack of software support. Of course this was different vendor with different business approach.
    Asus cheap boards like P8B75-M have support for Virtu MVP ... so it's doable and affordable but MSI wants to have an argument over selling more expensive boards. Now I totally get their marketing strategy.
    Thank you all for help, this topic can be closed.

  • P67A-GD80 B3 "cold boot" (RAM issues?)

    Hello everyone,
    First of all, my native langage is not english, so please excuse my grammatical mistakes. 
    Second point, i'm a noob, so if you could try to vulgarize your answer, would be really appreciated !
    So, there is my problem :
    I bought a computer with a P67A-GD80 B3 motherboard. It worked very well since the beginning, but I noticed sometimes it takes me one, two or several attempts to boot my computer (it turns on, immediately turns off with a "click", turns on, etc. And when it turns on, all the led and fans are ok).
    And recently, I started having windows warning messages : "please close X programmes, not enough memory".
    note : my RAM is G.SKILL Ripjaws X F3-12800CL9D-8GBXL 8GB 2X4GB DDR3-1600 CL9-9-9-24 Memory
    and finally one night I made the mistake to put my computer on sleep mode. Since I am unable to start it again (always that loop : turns on, turns off, turns on, ...)
    I looked on several forums and saw the cold boot issue, so I tried different things :
    - clear the cmos
    - move my RAM, tried with one stick, changed the plot
    nothing. And i'm uncomfortable taking off the components to test them or other stuffs since I don't want to break anything.
    So my question is : can it be my RAM which is dead (weird, because it doesn't work even with one stick and the other removed)
    I ordered a new RAM, but is there something else I should do, i'm quite lost actually.
    Thank you very much.

    Regarding your last post,you should pull out the battery for a few minutes.Cannot help any further as I'm new here and just beginning to understand hardware troubleshooting.
    Don't worry! Users here are very active and smart too! They will definitely help you with your problem.
    One thing I can make out with your problem is that as it is a memory issue then either your RAMs have gone wrong or its the CPU/Socket.
    I wrote CPU because the CPU has memory controller.So,check for some bent pins on the motherboard socket maybe?
    P.S. : Always keep a 2 GB DDR3 spare RAM (normal ones : 1333 Mhz) as it helps to troubleshoot the PC much easily.It just takes one component out of the suspected hardware failure :P(This was suggested to me by one of the moderators in here)

  • Z77A-G43 Gaming boot issue

    Alright, I'll make this as concise as possible as this board has, quite frankly, tried my patience all week.
    However that's another story for another time, to my current issue!
    The situation: I've recently bought a new mobo, CPU and RAM and in the process did a fresh Windows install just to clean everything up. No problems there so far. I have downloaded a game from a digital platform this afternoon and so, due to the fresh install, installed the official driver for my Microsoft controller. The restart dialogue box pops up as per usual and I close down what I'm doing and restart. I wait for my PC to boot and...it doesn't. It now just hangs at a black screen with a flashing cursor. (This screen comes after the splash screen, just in case it's relevant)
    The things I have tried thanks to Google-fu: I have removed all of my USB devices that are plugged into my PC.
    I have disabled legacy USB.
    I have changed the boot order, even making it so that my hard drive was the only enabled bootable device at one point.
    I have cleared the CMOS to use default settings.
    I have used a single RAM stick in Slot 2.
    I have attempted the flash a new BIOS using Mflash, however Mflash doesn't detect any BIOS files on my USB.
    I have tried to boot using a BIOS on my USB stick. They're detected, but then an issue pops up about the system data map being different from the BIOS data map so it won't boot.
    None of the suggestions above have gotten me past the flashing cursor. Has anyone else got any ideas? I'd like to not have to return the board as that would leave me without a PC for a few days, but if I have to then I have to.

    Sorry, I realised that more information would be required so I returned before checking out for the night.
    CPU: i5 3570K (stock speeds)
    PSU: XFX Pro850W Core Edition - Overkill now, but I had big plans when I ordered ha! Mice and men...
    RAM: 2x4GB of Corsair Vengeance (running at 1333MHz at the moment as that's what the mobo defaults to until XMB is turned on/voltage increased)
    Windows HDD: Seagate Barracuda 1TB
    GPU: Gigabyte 560Ti 1GB OC Edition
    OS: Windows 7 Home Premium x64
    I can't think of anything else that's relevant at the moment.
    Yes, it is the MS Xbox Wired controller (I tried to not use other company names here as I know some forums don't allow it).
    I had a look at that before, but the installer gave me the impression that it is to be used on the system you are trying to flash to, and therefore need to boot into Windows for it on the actual machine to then update that machine.
    The issue I had before was that the system was just not overclocking. I spent two days doing a huge amount of research trying to get my multipler to stick, but CPU-Z would always just report a stock speed so I returned my mobo to it's stock settings to make sure nothing went wrong by accident and decided to just try again at another time when I had more time to figure it out and play around. I read an obscene number of different posts from different forums, and each one had differing information but none of them worked.

  • P67A-G43 select boot device issue with GTX 970

    I recently tried to install a new GTX 970 and ran into an issue where I am asked to select the boot device every time I boot the pc. I uninstalled the driver for my video card before installing it. The system appears to be stable once it boots into Windows. However, when I swap back to the GTX 760, that was in the system previously, it boots straight into Windows without having to select the boot device? I have seen lots of issues on the forum about the 970 and older boards but nothing specific to mine. I am currently have BIOS version 1.A0 installed. Any help with this issue would be greatly appreciated. Thank you.

    Yes, you need to update. Following the below updates to latest official bios (5.4 aka E7673IMS.540)
    >>Use the MSI HQ Forum USB flasher<<
         A.) Download >>this archive<< and place it on your desktop. Do not decompress.
         B.) Download and install the Forum flash tool.
         C.) Insert your FAT32 formatted usb stick.
         D.) Make sure that all win 8 options are disabled. (Fast Boot etc) Also make sure the legacy USB is enabled.
         E.) Start the forum flash tool and select option 1. Then point the tool at the compressed archive we downloaded earlier. Then to your USB Flash Drive.
         F.) Boot to the USB 
         G.) Now follow the directions and let the tool flash
         H.) After flashing reinstall ME drivers in Windows: http://download.msi.com/dvr_exe/intel_amt81_win78_xp.zip

  • Z77a g43 boot issues

    We'll start with specs
    z77a-g43 motherboard
    560 gforce video card
    kingwin mach 1 psu
    wd caviar black 1tb hdd
    kingston 4gb ddr3 ram x2
    razer mouse and keyboard
    and then I don't remember the exact cpu but it's an i7 @ 3.4
    I having issues with the system booting. Every so often when it gets turned off it would get hung up on an A2 error during post and a restart or two would fix the issue, but it is no longer doing the trick. Reading around a little bit I tried unplugging just about everything in an attempt to just get it to boot. Having just the cpu, psu, ram, and mobo going I get an A0 error. Plugging the hdd back in I get a B4 error and with the keyboard added in I get the A2 error. After removing and reinserting a stick of ram it actually booted to windows. I cannot recreate this though so I am thinking it was a fluke. I tried plugging the gpu back in to get an A2 error and then the mouse to get a B4 error.
    I checked the cpu for signs of damage to see none, and I've flashed the cmos. When it hangs on one of these errors during post I can press tab and it will say that it is entering setup but then never does. I have never updated the bios so it is still sitting at the default.
    I've read a few posts talking about various compatibilty issues that can arise with an un-updated bios, but it has been running fine for just around a year. This only happens from a cold start and is the worst case of the issue to date. Any advice would be appreciated.

     With  both sticks in I was getting A2 and with each individually plugged in I get the same error.  Intermittently I  will see  the B4. Clearing cmos  let's me into the bios,  but if I haven't just cleared it,  entering the bios  just hangs forever. Bios  is showing all 8 gigs  of memory being read with system temps fine.  Voltages all looked fine too.  Attempting to save changes and reboot will leave me with a black screen. Discarding changes  will get me to Windows.  Also bios  reminded  me that  my cpu  is the i7-2600k if that helps.

  • MOVED: P6N Sli Plat. weird cold boot issue

    https://forum-en.msi.com/index.php?topic=116740.0

    yeah well if I set the timing to like 5-5-5-15 or something I'm sure it'll work fine.    But that's not the point...  Cuz if I have to set my timings to 5-5-5-15 just to get it up to the 889mhz that I need it.  I might as well just run the run in async mode at 4-4-4-12 800mhz.
    Seriously I have the weirdest ram.  I can run it at 4-4-4-12 800mhz with like 2.0 volts.  So There's like 0.2 volts of overclocking there.  But it just won't work at 889mhz.  And it not like it doesn't pass memtest or orthos.  The weird part is that it passes both at 889mhz at 4-4-4-12 timings at 889mhz.  The problem is that it won't start cold boot.    I'll have to press the power button and then press the reset button to get it to boot.  I guess that's not a really big problem, but having to press that reset button each time I cold boot is just really annoying. 
    If I set them to 4-4-4-12 at 800mhz, the computer turns on fine.
    I think the problem is the precharge for the ram.  I'll bet loosening the timing will make it work, but I just don't want to loosen those timings... 
    I just bought new ram so we'll see if that solved my problems.  :-P
    It might be the electron migration thing though.  I hear electron migration damage to things show up as random unpredictable problems.
    I would say my problems are random and unpredictable. 
    By the way, I just got a couple of fans for the ran slots.  They're sort of just jammed in there.  Kind of not elegant really.  But I now have TEN fans in the computer.  I hope that helps my ram overclocking. 

  • 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.
    Board: MSI Z77A-G43
    Bios: Version 296
    VGA:   Sapphire HD7850 1GB
    PSU:   Modecom Volcano 550W
    Intel Core i5-3570k
    MEM: Kingston 4GB 1600MHz
    HDD: 2xSSD
    Without OC
    OS: Windows 7 64bit Professional
    Can You help me somehow, maybe I did not check something else?

    Quote from: The CPU Whisperer on 22-April-13, 16:06:05
    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.

  • 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?

  • Z68A-GD80 B3 Random cold boot issues

    No mater if system is set to optimized defaults or Overclocked I randomly get odd boot behavior ranging from slow boots to no boots
    Symptoms:
    delays at post on blank screen with exception of "A2" and or "B3" displayed in the bottom right hand side of the screen.
    Generally after stops looking for a floppy to boot to, which makes no sense at all there is not even a floppy header or bios option to disable.
    I can have three days in a row with no boot issues at all.
    Note: PC and all peripherals are connected to My Tripp Lite 1200w UPS which is connected to a dedicated 20 amp circuit with hospital grade receptacle. 
    I have the board speaker attached to the board to broadcast the beep codes.
    When a good boot happens I hear three beeps and a final short beep all in fairly quick succession.
    During a failed post the beeps come slower with a greater duration between beeps and one less beep
    Sometimes it sounds like 5 beeps in total but that is with a good post 4 quick beeps and a final marginally longer beep.
    Since their is no post code display with this board I'm left with wondering what these beeps mean on the Z68 boards.
    Also of note the Corsair H70 CPU cooler I have attached to the mobo CPU header for the pump and the Mobo fan 2 header for the H70 fans, so I can monitor the RPMs start very slowly not unlike a jet turbine begins slowly and gradually builds momentum. I only mention this because it does not act this way on other boards I have tried the cooler. Especially when bios setting were set properly which bring me to what I have tried to resolve the situation.
    I've been able to stabilize the board with OC genie and manually at 4.8, 4.7, and 4.6 MHz with 1600 and 1866 memory speeds. To be clear I consider, 20 pass max mem of LinX, 10 hrs prime 95 w/o error and 200% coverage HCI design Memtest (two instances "usable" and "all remaining") with no errors stable.
    Further more I've been able to stabilize Turbo Boost at x49 1core, x48 2cores, x47 3cores and x46 4cores with little more than a Vcore adjustment away from default settings.
    The issue remains intermittent cold boot issues.   
    I haven't had a system pass these test and have cold boot issues since the NF2 days.
    What I've tried:
    bumping Vcore way past minimum required to boot to any given clock down to 4.2 (1.2v)
    bumping CPU I/O same as above
    running at default
    running at default with XMP
    running default manually set RAM timings and volts
    running with the above with EuP 2013 disabled
    Smart Fan disabled and enabled
    disable a boot devices except actual boot drive
    tried two different Corsair 850 watt PSU.
    Questions:
    What are the beep codes for this board?
    When will we see a bios update to fix the multiple UEFI interface problems and possibly this issue as well?
    I thought I bought an enthusiast motherboard yet RPMs from motherboard fan headers are only monitored 1&2 headers.
    I use Aida64 Extreme to monitor temps and voltages but conspicuously missing are things like VTT, SA and PLL voltages and the temps for same.
    Is this normal?
    are they lacking sensors on this board?
    or do I have a defective board?
    Final Q
    When Aida64 is running CPUz current an previous version will not run on this board. I have spoken to the developer of CPUz Franck and Aida and for the moment it seems to be related to this board only but the failure is consistent even after format and reload. CPUz and Aida64 are known to work/coexist on similar Z68 boards. So my question is, Is this a known issue for this board?
    Amendment to the system specs below
    I have two opt drives attached to the SataIII (white) headers in AHCI mode the Blue Ray drive is not discoverable in IDE mode. Blue Sata ports 3,4 are configured in a Raid-0 array and 5 & 6 have WD 640 Caviar Blk drives respectively port 7 is empty.

    My apologies for posting this in the wrong section. Can a mod move it to the appropriate forum. TY

  • K8N Neo4-F 1.D BIOS cold boot issue

    A couple of months ago I flashed my BIOS to the latest version for this board, 1.D. Since then, I've noticed that sometimes on a cold boot, the computer won't complete a POST. I have to hit the reset button and warm boot for the machine to POST normally. Once the computer POSTS it otherwise works fine, so this is a minor annoyance at most. However, sometimes after the warm boot, the BIOS will warn me that overclocking has failed, and that the BIOS has reverted to default settings (although I am NOT overclocking), although hitting the DEL key and entering CMOS it's clear that the BIOS has not been reset to defaults (nor would I want it to be). After hitting F1 to continue, the computer boots as normal. Is this a known issue with this BIOS version?
