Z77a-g43 cold boot overclock issue

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.

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.

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?

Z77A-G43 Issue - Bios not working

Dear Forum,
I have a quite strange issue with my brand new system.
Specs first:
MSi Z77A-G43 BIOS 2.2/2.3, i5 3570K, Win7 Professional 64 bit
G.Skill Value Series 8GB DDR3-1333 Kit
be quiet! Straight Power E9 580 Watt CM
Gigabyte GeForce GTX560 Ti
OCZ Vertex 120GB SSD
Western Digital Caviar Blue 500GB
LG GH24NS70
Problem description:
All parts are brand new. Machine was assembled (antistatic wristband used), Display connected to PCIE-Nvidia gfx card.
Display showed post codes (99, A2) in low resolution and got stuck with a blinking cursor in the top left corner.
After some cable checking I switched to the built-in gfx (from CPU) and the machine booted into bios (v.2.2) after showing the MSI logo.
Whenever I tried to change or even view the bios settings, the machine froze and had to be hard reset.
I installed Win7 without a flaw and updated the bios to 2.3 using Live Update. No errors.
Now whenever I trie to access the bios (hitting DEL) the bios image (blueish) pops up for a short moment and the machine reboots. Nothing else I can do there. It still booted though into windows.
I did the CMOS-reset which showed the initial "settings have been reset, hit F1 for setup or F2 to continue" message but when hitting F1 it again flashed the bios image for a microsecond and rebooted.
Windows still booted normally, when starting Click Bios II application it showed the loading screen but nothing happened. So I decided to reflash 2.3 Bios.
--> Nothing changed
I then flashed the Bios down to 2.2 using the MSIHQ-Flash utility (awesome tool) which lead to the same effect as before:
I could access the bios but could not change any settings, the machine froze. The click-Bios application started though.
Now I have two questions:
1) What's the matter with the board/bios? I can still return the mainboard to the vendor but would rather like to see this issue fixed
2) Any ideas with the non-running PCIE-graphics card? Could this be related to the mainboard/bios as well? PSU has 580W and all cables were connected properly.
Thanks for any input that might help..

Wouldn't even bother trying anymore with v2.2 since it needs v2.3 to fully support the CPU you have. Recommend to stay with v2.3 since it updates the Management Engine. Going to v2.2 may be causing a chip corruption of some kind.
Not sure what kind or brand of keyboard is involved here, but try with a generic USB one. I had to enable F-Lock on my keyboard to make it go to the UEFI/BIOS using the Delete key. Test with one RAM stick only in the primary dimm slot. Depending on the manual revision, that is either DIMM1 or DIMM2. Update to v2.3, remove the PSU power cord, remove the battery for awhile, clear CMOS and reset, and test again.
I did use another keyboard, I did a CMOS reset, I have only one module in DIMM2 as stated in the manual. I guess I went through all usual troubleshouting steps. some things in my system don't like each others.
what I did not do so far is comparing the serial of the old and new mainboard. will do that tonight - I srsly hope they didn't send the faulty one again..

Z77A-G43 Computer Reboots after Shutdown Issue

I recently built a new PC using the MSI Z77A-G43 motherboard and installed Windows 7. Everything seems to work fine except one thing - the PC immediately restarts itself after It shuts down through the normal Windows shutdown process. I have read many forums on this similar problem and have tried a few things such as 1) unchecking automatic restart in the system properties dialog box. 2) Changing the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon "PowerdownAfterShutdown" to a '1'. 3) Updated Windows fully as well as installed the latest drivers for everything. 4) Made sure that in BIOS all of the Wake Up Events are set to Disabled. In fact I even changed Wake Up Event By [BIOS] to By [OS]. 5) Cleared BIOS by taking the battery out for 5 minutes, as well as updating BIOS to the latest version 2.2. 5) The only IO card is the graphics card and I switched that out too and it did not make a difference. None of these options seems to correct the problem. I am convinced there is something wrong with this motherboard. Has anyone else had this issue with this or another motherboard? Anyone have any other solutions?

Sometimes a short within the chassis can caused such issue as well.
I suggest that you try booting and shutting down the hardware out of the chassis and see if you can replicate the issue.

Z77A-G43 issue with SATA drive

This is wierd
I have 4 Hitachi drives all of 1TB, perfectly working on old PC.
Today have decided to transfer them into new PC:
MB: Z77A-G43
BIOS: 1.20
CPU: Intel g2020
Primary drive is Intel SSD 120G series 330
I have attached 3 HITACHI drives successfully, they are all working fine.
but particular one forces MB to reboot before BIOS screen, last code seen on screen is A2?
Then I have decided to put dedicated controller 1st I took SilImage 3512 SATA/RAID Controller
- no changes computer reboots before post screen
After I took VIA VT6421 SATA/RAID Controller
- no changes computer reboots before post screen
searched web, found nothing useful.
any ideas what might causing this?
EDIT: tested controller SiI3512 on old PC and trouble HDD, everything works just fine :/
read AMIBIOS codes:
0xA0 IDE initialization is started
0xA1 IDE Reset
0xA2 IDE Detect
0xA3 IDE Enable
0xA4 SCSI initialization is started
0xA5 SCSI Reset
0xA6 SCSI Detect
0xA7 SCSI Enable
0xA8 Setup Verifying Password
A2 is ide ? what ide ? I give up.
it seams to me that this board is broken in several ways
- non working DVI
- faulting with valid SATA drive
what else awaits me on this road

Quote from: flobelix on 07-May-13, 04:27:27
using IDE previously and now AHCI might trouble Windows but system would none the less post. At least you should get past IDE detection but hanging at A2 means it doesn't.
I'm wondering about your statement you had been using SilImage 3512 SATA/RAID Controller and VIA VT6421 SATA/RAID Controller. Are these PCI add-on cards? Did you try all SATA ports controlled by the Z77 chipset. Are the drives used are all identical? Is the issue only happening with one particular drive or anytime you attach a fourth hdd no matter which one it is?
About the performance difference from AHCI to IDE the differences are minimal. Should be almost irrelevant for the hdds.
My discoveries:
Using sata mode IDE with windows installed in AHCI mode == windows hangs during loading (BSOD), probably missing drivers or similar.
Also I am unsure what A2 code means but I have noticed it is displayed while bios post screen shows up with the list of installed drives during normal boot.
And is also last code I see when I attach problematic drive resulting in reboot loop.
To be honest I haven't tried all SATA ports on board for sure I haven't tried SATA 1 (1st white) as there is my SSD drive.
But I have tried almost all other ports. I can try them all, but I don't think this will solve the problem.
I don't think problem is in what slot I put my drive, since same behavior is with SATA/RAID controllers.
And whit this SATA/RAID controllers this drive is working perfectly normal on other PC.
No not all drives are identical but I have exactly same drive as this one, and all drives are hitachi:
* HDT721010KLA330 working fine
* HDS721010SLA360 working fine
* HDS721010CLA332 (1) working fine
* HDS721010CLA332 (2) problematic drive == reboot loop (when its single drive or with others).
True I haven't tried to detach Intel SSD and leave problematic drive as only drive in system, I may try this tomorrow)
funny part is that HDS721010CLA332 (2) is working fine when I hot plug it.
Checked firmware version on both drives, and both drives have identical firmwares.
Only difference I know off is that working drive has 1 partition, and problematic drive has 2 partitions.
EDIT: forgot to say it passed SMART test, everything was green (hitachi sw), while hdd sentinel reported 1 bad sector but saying estimated drive working days > 900 days and degree was 98% I am guessing because of that 1 bad sector and too many working days (years) behind him.

MOVED: P6N Sli Plat. weird cold boot issue

This topic has been moved to Overclockers & Modding Corner.
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.

Internet Network Issues on Z77A-G43

I'm not sure what the issue is. Could be a BIOS setting or software but my network has been problematic. At first it would be a situation where I wouldn't be able to see other networks after waking from sleep mode. Now it seems my internet connection keeps stopping but I can still see other PC's on the network. When I disable the network device and re-enable the network it works again. Sometimes it will be stable for hours, sometimes it stops working after 30 minutes. I've tried reinstalling drivers, disabling energy saving and I'm already on the latest BIOS.
My system is as follows
MSI Z77A-G43
Intel i5 3750k
2 x 4Gb GSkill Sniper DDR3 1600 1.25v
Sapphire Radeon HD 7850 2Gb OC
Transcend 64Gb SSD
Corsair HX750
Really not sure what to do. I've tried running virus scans, spybot scans and registry scans but all come up clean.
Please help.

Check the mac address and make sure that it matches the sticker on the NIC.
Update the drivers to the most recent:

There are newer Beta bios as well if you scroll down from the official one.
